Note More detailed specifications are in the HP LaserJet 5Si and 5Si MX User’s Guide, and the HP LaserJet Printer Family Paper Specification Guide. (See “Related Documentation and Training Media” later in this chapter.) Paper To achieve the best possible print quality and avoid paper jams, follow these guidelines for selecting paper: • Use only copier grade paper that meets all specifications in the paper specification guide.
Adhesive Labels Use the following guidelines when selecting labels: Caution Tray 1 is required for printing adhesive labels. Print labels to the Face-Up Bin only. This printer does not support use of labels with any exposed spaces. Do not attempt to print on label sheets after any of the labels have been removed from the sheet. Damage to the printer may result. • Labels must be arranged on the carrier sheet so that there are no exposed spaces on the sheet.
Storing Print Media • Store paper in its ream wrapper until ready to use. • Re-wrap partially used packages of media before storing. • Stack each carton upright and squarely on top of the other. • Store envelopes in a protective box to avoid damaging the envelope edges. • Keep stored media away from temperature and humidity extremes. • DO NOT store cartons or reams directly on the floor where they will absorb a higher moisture content. Instead, place cartons on a pallet or on shelves.

Repair of the printer normally begins with a three-step process: • Step 1: Isolate the problem to the major system, i.e. the host computer, the network and/or server, or the printer system. • Step 2: Determine if the problem is located in the accessories or in the printer engine. • Step 3: Troubleshoot the problem using the procedures in Chapter 7. Once a faulty part is located, repair is usually accomplished by assembly level replacement of Field Replaceable Units (FRUs).
Consumables The printer has two consumables, the toner cartridge and staple cartridges, which may be ordered directly from Hewlett-Packard. Refer to Chapter 8 for ordering information. Toner Cartridge Life The Toner Cartridge (C3909A) is designed to simplify replacement of the major “consumable” parts. The toner cartridge contains the printing mechanism and a supply of toner. At 5% page coverage, a toner cartridge is guaranteed to print approximately 15,000 images (see Figure 1-6).
While Hewlett-Packard does not prohibit the use of refilled toner cartridges and non-HP staple cartridges during the warranty period or while under a maintenance contract, their use is not supported for the following reasons: • Repairs resulting from the use of refilled toner cartridges and non-HP staple cartridges are not covered under the Hewlett-Packard warranty or maintenance contract.

This warranty entitles you to standard warranty services for your printer and accessories and is available from HP worldwide. However, there may be local variations in the level of warranty service. You should contact the local HP Service Center to check for the applicable local warranty in your country or province. One-Year On-Site Limited Warranty Hewlett-Packard warrants its computer hardware products against defects in materials and workmanship for a period of one year from purchase by the end user.
Note The use of non-Hewlett-Packard toner cartridges alone does not affect either your warranty or any maintenance contract you may have purchased. However, if an HP LaserJet printer failure or damage is found to be attributable directly to the use of a non-HP toner cartridge, HP will not repair the printer free-of-charge. In this case, standard time-and-materials charges will be applied to service your printer for that particular failure or damage.

4-2 Maintenance and Adjustments
Cleaning the Printer and Accessories To maintain the print quality and paper performance, thoroughly clean the printer and the paper handling accessories: • Every time you change the toner cartridge. • After printing approximately 15,000 images. • Whenever print quality problems occur. Clean the outside surfaces with a lightly water-dampened cloth. Clean the inside with only a dry, lint-free cloth. Use the guidelines listed in Table 4-1. Observe the warnings and cautions below.
Cleaning the Printer 1 Before you begin these steps, turn the printer OFF and unplug all cords. 2 Open the top cover of the printer and remove the toner cartridge. WARNING! Avoid touching the adjacent fusing area. It may be HOT. Caution Do not touch the transfer roller (A). Skin oils on the roller can reduce print quality. If toner gets on your clothes, wipe it off with a dry cloth and wash your clothes in cold water. Hot water sets toner into fabric.
Table 4-1 Cleaning the Printer Component Cleaning Method/Notes Outside Covers Use a water-dampened cloth. Do not use solvents or ammonia-based cleaners. Inside General Use a dry, lint free cloth. Remove all dust, spilled toner, and paper particles. Paper Pickup, Feed, and Retard Rollers Use a water-dampened lint-free cloth. Separation Pad Use a dry lint-free cloth. Registration Roller Use a dry lint-free cloth. Transfer Roller Use a dry, lint-free cloth. DO NOT TOUCH with your fingers.
Preventative Maintenance The user-conducted preventive maintenance cycle for this printer is every 350,000 images. The part numbers for the preventive maintenance kits are C3971A for the 100V printers, and C3972A for the 220V printers. The kits contain the following replacement parts: one Fusing Assembly, one Transfer Roller Assembly, and six Feed/Separation Rollers (two each for Trays 2, 3, and 4).
Tray 2 and 3 Adjustment Procedure The paper trays are mechanically aligned to the printer chassis at the factory. Perform this procedure ONLY if a paper tray has been replaced with a tray other than the original factory installed unit, or if the top margin of the image area is off-center more than 0.5 mm (0.02 in.) The adjustment procedure is identical for Trays 2 and 3. Note Before performing this procedure, check that the margins in your software application are properly set.
Note Refer to Figure 4-2. Each adjustment notch changes the physical position of the tray by 0.5 mm (0.02 in). Moving the lever counter-clockwise moves the tray inward and increases distance A. Moving the lever clockwise moves the tray outward and decreases distance A. Figure 4-2 Tray 2/3 Position Adjustment 4 If distance A is greater than distance B by more than 0.5 mm (0.02 in), move the adjustment lever clockwise one notch. 5 If distance A is less than distance B by more than 0.5 mm (0.
Tray 4 Adjustment Procedure In some cases, the registration from Tray 4 (HCI) causes print to start too close to the edge of the paper. This situation is not a typical occurrence. In most cases the Tray 4 offset is fine. Although this may or may not be within specification, it is unacceptable to some users. Perform the following adjustment procedure to correct the situation. 1 2 3 4 With the HCI stand-alone, remove left, right and rear covers from the HCI. Remove the vertical transfer unit.
10 Tighten both screws. 11 Reassemble the vertical transfer unit. 12 Make sure all the cables (vertical transfer unit and paper deck drive assembly) are reconnected. 13 Reinstall left, right, and rear covers to the HCI. Note The locating pin position at the middle could still be unacceptable for some customer’s applications. If so, repeat the procedure by moving the locating pin further back and testing the margin obtained.

Basic Printer Functionality This chapter presents a functional overview of the printer and the printing processes.
Printer Functional Block Diagram Figure 5-1 is a functional block diagram of the printer showing the basic paths for signal, control, and media.
Power Distribution System The AC and DC power supply circuits are contained in the Low Voltage Power Supply (LVPS). The high voltages required for image formation are generated by the High Voltage Power Supply (HVPS). The Low Voltage Power Supply and Distribution System is illustrated in Figure 5-2. Refer to the Reference Diagrams at the end of Chapter 7 for more details.
AC Power Distribution The AC power circuitry supplies AC voltage whenever the power cord is connected, and the power switch is ON. A toner cartridge must be installed and the top access door must be closed before AC voltage is supplied to the DC power circuits or the Fusing Assembly. Overcurrent/Overvoltage Protection There are two overcurrent/overvoltage devices in this printer: The resettable circuit breaker (CB101) shuts off AC input power to the LVPS in case of an AC overcurrent condition.
High Voltage Power Distribution The High Voltage Power Supply (HVPS, see Figure 5-4) applies a DC biased AC voltage to the primary charging roller and the developing roller, and a programmed DC voltage (depending upon the phase of the printing process) to the Transfer Roller. Refer to the General Timing Diagram (Figure 5-22) at the end of this chapter for HVPS timing information.
Formatter System The Formatter PCA is responsible for the following: • Controlling the PowerSave mode. • Receiving and processing print data from the various printer interfaces. • Monitoring Control Panel inputs and relaying printer status information (through the Control Panel and the Bi-Directional I/O). • Developing and coordinating data placement and timing with the print engine. • Storing font information. • Communicating with the host computer through the Bi-Directional Interface.
Note Printer error messages override the PowerSave message. The printer will enter PowerSave mode at the appropriate time, but the error message will continue to be displayed. Resolution Enhancement (REt) The Formatter PCA contains circuitry for Resolution Enhancement technology (REt), which modifies the standard video dot data on its way to the DC Controller to produce “smoothed” black-to-white boundaries. REt is user-controllable (ON or OFF) from the control panel, or from some software applications.
DC Controller System The following systems and functions are controlled by the DC Controller PCA: • • • • • • DC Power Distribution (+5V DC, +12V DC, +24V DC) Laser and Scanner Drive Paper Motion Monitoring and Control (photosensors and flags) Clutches (registration, tray pickup, and Tray 1 feed) Engine Test Motors (Main Drive, Scanner, and Fans) Figure 5-2 shows the Low Voltage Power Supply and Distribution System.
Engine Test Microswitch The Engine Test Microswitch, located on the DC Controller PCA, is activated manually through the square access hole at the right rear of the printer (see Figure 6-4). This switch causes the print engine to perform an internal self test diagnostic which bypasses the Formatter PCA and then prints a full page of black parallel lines. This test is useful for troubleshooting printer problems because it isolates the print engine from the Formatter PCA.
Image Formation System Laser printing requires the interaction of several different technologies (such as electronics, optics, and electrophotographics) to provide a printed page. Each process functions independently and must be coordinated with the other printer processes.
Toner Cartridge The toner cartridge is the “heart” of the Image Formation System. It houses the cleaning, conditioning, and developing steps of the process. The toner cartridge contains the photosensitive drum, primary charging roller, developing station, toner cavity, and cleaning station. Including the components that wear, degrade, or are consumed in a customer replaceable toner cartridge eliminates the need for a service call when replacement is required.
Drum Cleaning The cleaning blade inside the toner cartridge is in contact with the surface of the drum at all times. As the drum rotates during printing, excess toner is removed from the drum surface and stored in the waste toner receptacle inside the toner cartridge.
Drum Conditioning After the drum is physically cleaned, it is conditioned by applying a uniform negative charge across the surface of the drum with the primary charging roller, located in the toner cartridge. The primary charging roller is coated with conductive rubber, charged with an AC current which erases any residual charges, and produces a uniform drum surface potential. The AC current is centered around a negative DC bias which changes according to the Print Density setting.
Image Writing During the writing process, a modulated laser diode projects a beam onto a rotating six-sided scanning mirror. As the scanning mirror rotates, the beam is directed through a set of focusing lenses to a direction changing mirror which reflects it through a slot on the top of the toner cartridge, and onto the photosensitive drum. The beam sweeps across the drum and discharges the negative potential wherever it strikes the surface.
Image Developing The developing process changes the latent electrostatic image into a visible image by depositing negatively charged toner particles on the exposed areas of the drum. The developing station is located inside the toner cartridge and consists of a metallic cylinder that rotates around a fixed magnetic core. The developing cylinder is charged with an AC current that is centered around a negative DC bias.
Image Transferring and Media Separation During the image transferring process, the toner image on the drum surface is transferred to the media. A positive charge applied to the back of the media by the transfer roller, causes the negatively charged toner particles on the drum surface to be attracted to the media. The small diameter of the drum, combined with the stiffness of the media cause the media to separate easily from the drum. The static eliminator teeth also help separate the paper from the drum.
Image Fusing The Fusing Assembly bonds the toner particles into the media with a heated fusing roller and a soft pressure roller. There are two levers on the Fusing Assembly which adjust roller pressure for single sheets (down position), or envelopes (up position). Both levers must be set to the same position. The fusing roller contains two quartz-halogen lamps that provide heat for the fusing process. Fusing temperature is monitored by the DC Controller PCA, via thermistor TH1.
Paper Paths and Components Printer, Duplex Unit, and Envelope Feeder The components of the printer paper path are illustrated in Figure 5-14. Figure 5-15 and Table 5-1 illustrate and describe all of the printer sensors, solenoids, clutches, motors, and fans.

2000-Sheet Input Unit Operation All communication and control of the 2000-Sheet Input Unit (and the Multi-Bin Mailbox/Mailbox With Stapler) is through the External Paper Handling (EPH) PCA mounted on the Formatter Assembly. These instructions are sent to the 2000-Sheet Input Unit controller PCA located behind the back cover. The main components of the 2000 Sheet Input Unit and their functions are listed in Table 5-2.

Multi-Bin Mailbox Operation All communication and control of the Multi-Bin Mailbox (and the 2000-Sheet Input Unit) is through the External Paper Handling (EPH) PCA mounted on the Formatter Assembly. These instructions are sent to the Multi-Bin Mailbox controller PCA located at the bottom of the frame. The main components of the Multi-Bin Mailbox and their functions are listed in Table 5-5.
trailing edge is sensed by PSFaceUp. The Flipper Roller motor (M3) then reverses and feeds the sheet down between the transport belt and the metallic tape into the delivery head at the accellerated speed of 500 mm per second. There is a magnetic strip on the guide behind the transport belt. When a sheet of paper is fed down the transport belt, the magnetic attraction between the metallic tape and the magnetic strip holds the paper against the transport belt as it is pulled downward to the delivery head.
Stapling Unit Components The components of the Stapling Unit paper path are illustrated in Figure 5-20. Figure 5-21 and Table 5-6 illustrate and describe all of its sensors and motors.

the left wall of the Stapling Bed. This cycle is repeated until the amount of sheets to be stapled is reached (with a maximum of 20). Stapling Cycle The Sliders move the stack of sheets to the stapling position. The Registration Pusher applies slight pressure to the stack of sheets toward the left wall of the Stapling Bed, where the stapler is located. Then the stack of sheets are stapled. Eject Cycle The stapling bed sliders offsets the stacks or jobs.
Printer Input Sources Paper Size Switches The paper guides in Trays 2 and 3 operate four levers at the back of the trays which activate the size sensing switches (SW1601 through SW1604) mounted in the printer chassis. Table 5-8 compares paper sizes to switch conditions.
Printing from Tray 1 The presence of paper in Tray 1 is detected by the Tray 1 Paper Present Sensor (PS1301). The lifting plate pressurization solenoid (SL2) is then activated, releasing the plate which applies upward pressure on the paper, causing it to contact the Tray 1 pickup roller. The Tray 1 Feed Clutch (CL3) turns on at this time and feeds the paper from Tray 1 to the registration position. The remainder of the Tray 1 print process is identical to the Tray 2 and 3 process, described above.
Paper Jam Detection The PIU Sensor (PS2), the Registration Sensor (PS1), the Fuser Delivery Sensor (PS1403), and the Face-Down Delivery Sensor (PS1402) detect when paper is moving through the printer (see Figure 5-15 for sensor locations). If a paper jam is detected, the DC Controller immediately stops the printing process and causes a 13.x PAPER JAM message to be displayed on the control panel.

Troubleshooting Process The troubleshooting process is a systematic approach that addresses the major problems first and then other problems as you identify the causes for printer malfunctions and errors. The Troubleshooting Process, Figure 7-1, on the following two pages, illustrates the major steps for troubleshooting the printing system. Each heading depicts a major troubleshooting step. A YES answer to the questions allows you to proceed to the next major step.

7 Troubleshooting Figure 7-2 HP LaserJet 5Si / 5Si MX / 5Si Mopier Troubleshooting Process Troubleshooting 7-5
Power-On Overview It is important to have the printer’s Control Panel functional as soon as possible in the troubleshooting process so that the printer’s diagnostics can assist in locating printer errors. Table 7-1 Power-On Problem Action 1. Is AC power available at the printer’s power receptacle? Verify. See Table 1-7. 2. Is the printer’s ON/OFF switch set to ON? Push the switch to the ON position. 3.
Figure 7-3 7 Troubleshooting Fan Location and Airflow Note When the printer is in PowerSave mode, the fans are off. Table 7-2 Fans Fan Number Fan Name Fan Location 1 Laser/Scanner fan Exhaust air flows from the back of the printer, on the left-hand side of the fusing assembly. 2 Low-voltage Power Supply Lower right-hand corner of the printer. 3 Formatter (intake) Intake fan directly above the input power receptacle.
Engine Test The engine test verifies that the print engine is functioning correctly. The Formatter PCA is completely bypassed during an engine test. This test is very useful for isolating printer problems. The engine test prints a full page of horizontal lines across the entire printable area, and is also useful for checking and adjusting registration. The engine test prints from Tray 3 only, and can be activated with the Formatter PCA removed.
Display Overview Use the printer’s Control Panel to access the error log to troubleshoot the printer. With the printer’s test menu, you can access the printer’s error log to display more information about the current error. The error log retains the printer’s last 50 error messages. Display and Evaluate the Error Log If the printer cannot print or move any paper, follow these steps to display the error log: 1 2 3 4 5 Press [Menu] until TEST MENU appears. Press [Item] until SHOW ERROR LOG appears.
Configuration Use the configuration pages to verify the proper installation of accessories, options, and personalities. When you print the configuration pages, the printer checks its internal controller and I/O interface, then prints two pages. One shows the overall printer configuration, and the other one shows the current menu settings. Refer to Figure 7-5 and Figure 7-6 or information about interpreting the configuration page.

Communications Link (C-Link) Cables Figure 7-7 Communications Link (C-Link)Cables, Supported Daisy Chain Connections All C-Link cables have a single dot molded into the device output connector cable end, and two dots molded into the device input connector cable end. The devices may not be recognized by the External Paper Handling Controller if the cables are not connected exactly as shown in Figure 7-7.
Image Quality When you are working with customers, obtain a print sample before you begin troubleshooting their printer. Ask the customer to explain the quality they expect from the printer. The print sample will also help clarify the customer’s explanation. Table 7-4 Image Quality Action Obtain a print sample from the customer. 2. Does the problem repeat on the page? Use the Repetitive Defect Ruler in the "Reference Section." 3.
Check the Toner Cartridge Image formation defects are often the result of toner cartridge problems. If there is any doubt, always replace the toner cartridge before troubleshooting image defects. Use the following check list to ensure that the toner cartridge is still operable. • Ensure that the toner cartridge has toner. • • • • Note Full toner cartridge weight =3000 grams (106 oz) Empty weight = 2200 grams (80.5 oz) Check the expiration date of the toner cartridge (stamped on the cartridge box).
Error Log Use the error log to diagnose and troubleshoot printer errors and intermittent failures. Also, you can use "Show Error Log" under "Display and Evaluate the Error Log" discussed earlier in this chapter. Print and Evaluate the Error Log The printer’s internal error log stores the last 50 errors and can be printed. To print the error log: 7 After printing the error log: • Check the error log for specific error trends in the last 10,000 printed pages.
Whenever a 13.xx appears on the Control Panel, a good practice is to clear all the paper from the printer, take the printer offline, and print the error log. If you cannot print the error log, you can still display it on the display panel. Write the error next to the last error logged. The last error is the error at the top of the error log printout with the highest number in the leftmost column.
Communication Ask the customer to run a print job from the host system. If the print job is successful, proceed to the following step, “Verification.” Verify Communication Print the PCL configuration page and study the HP MIO block. The MIO block will appear on the bottom portion of the configuration page. An example of a properly operating MIO block appears in Figure 7-9.
• The "Novell Status" block should state the Novell printer server name to which the printer is connected. If the node name reads "NPIxxxxxx" (xxxxxx=last six digits of the MIO’s LAN address), the MIO card has not been configured for a Novell server. This could indicate that the card is operating under a IPX protocol other than Novell. Consult with the network administrator if the Node Name is not present. • In the TCP/IP protocol block, the default IP address is "192.0.0.192.
Verification Paper Path Test Using the error trend information from Step 5 (Error Log), you may verify a specific printer paper path with the paper path test. You must first set the desired paper destination in the configuration menu and then select the paper path test. The paper path test menu will allow you to select the desired paper source and number. Note Multi-Bin Mailbox and Stapler are not supported with the LaserJet 5Si HM (C3124A).
Figure 7-10 Paper Path Test Source and Output Selection Customer Print Job Ask the customer to send a print job from the problem source(s) to the problem destination(s). Try to recreate the paper jam errors by having the customer do typical print jobs and the type of print job that has been causing the paper jams. Note When verifying print jobs, ensure that all of the settings are selected as desired.
Reference Control Panel Messages and Errors Printer messages displayed on the control panel provide five categories of information. Each message category is assigned a priority. If more than one condition occurs at the same time, the highest priority message is displayed. When it has been cleared, the next priority message will be displayed, and so on.

Drum Rotation Functional Check The photosensitive drum, located in the toner cartridge, must rotate for the print process to work. The photosensitive drum receives its drive from the Main Drive assembly. To verify whether the drum is rotating: 1 Open the top cover. 2 Remove the toner cartridge. 3 Mark the cartridge’s drive gear with a felt-tipped marker. Note the position 4 Install the toner cartridge, and close the top cover. The start-up sequence should rotate the drum enough to move the mark.
High-Voltage Power Supply Check The High-Voltage Power Supply PCA provides the necessary voltages for the electrophotographic processes. A method for verifying the high-voltage system is given below: Toner cartridge connection points Visually inspect the four connection points on the inside right end of the toner cartridge. If they are dirty or corroded, clean the connections. Clean using alcohol only. If damaged, replace the toner cartridge.
Troubleshooting Checks Paper Jams Paper jams occur most often when: • Paper trays are not correctly loaded. Make sure the paper is loaded with the arrow pointing UP in Tray 1, and DOWN in Trays 2, 3, and 4. • The print media does not meet the specifications listed in the HP LaserJet Printer Family Paper Specifications Guide. The printer monitors the timing of four sensors to determine that a paper jam has occurred: PS2, PS1, PS1403, and PS1402 If a paper jam occurs, the printer will display a 13.
Figure 7-27 shows the possible locations for most of the paper jams. Figure 7-27 Paper Path Jam Locations 1. Toner cartridge area 6. Front Door 2. Tray 1 pick-up roller and feed area 7.

Clearing Paper Jams Note: Open and close all printer covers to clear the paper jam message. After removing a sheet of paper, you may need to check other areas to ensure that all paper has been removed. Whenever a sheet of jammed paper becomes badly shredded, it is a good idea to carefully piece all parts together to be sure you haven’t overlooked some small part. All portions of a jammed piece of paper must be removed or you may run into repeated jams.
General Troubleshooting Information Miscellaneous Problems and Solutions The following lists symtoms and typical solutions to those problems. Abnormal noises are evident; grinding or chattering when main motor energized. From EP Area: 1 Replace Toner Cartridge. 2 Replace Main Gear Assembly.

B I/O Information IEEE 1284 Parallel Cable Information The IEEE 1284 parallel interface is compatible with Centronics parallel interfaces. To take advantage of its enhanced capabilities such as bi-directional communication between the computer and printer, faster transmission of data, and auto configuration of printer drivers the customer must have: • Support in software applications for these features. • A parallel cable with the correct pin configuration (see Figure B-1 on the following page).
Parallel Cable Pin Configuration For best results, use the C2951A cable, or equivalent. Caution Ensure that all power and interface cables on the printer and host computer are properly grounded in compliance with local codes.
Connecting to LocalTalk Networks The printer does not come with a LocalTalk network cable. Use a standard LocalTalk network cable and connector kit, such as the HP LocalTalk Network Cable Kit, part number 92215N. You will need one connector kit for each printer on the network, and another for each Macintosh computer on the network. Connecting to the END of a LocalTalk Network Figure B-2 Connecting to the END of a LocalTalk Network 1 Disconnect the printer from its power source.
Connecting to the MIDDLE of a LocalTalk Network Figure B-3 Connecting to the MIDDLE of a LocalTalk Network (1 of 2) 1 Disconnect the printer from its power source. Insert the new connector box cable into the LocalTalk port of the printer. 2 Insert one end of the new cable into the connector box. 3 Place the other end of the new cable next to a connector box on the network. 4 Unplug one cable from the connector box on the network.
Connecting to a Network. The printer supports up to four different cables: IEEE 1284 parallel, (Figure B-5, callout 1), BNC (ThinLAN) (Figure B-5, callout 2), 10Base-T (RJ-45) (Figure B-5, callout 3), and DIN-8 (LocalTalk) (Figure B-5, callout 4). Select the appropriate interface cable from those shown below for the system and connect the cable or cables to the printer.
DIN-8 (LocalTalk) Interface Plug the end of the DIN-8 cable into the LocalTalk port on the HP JetDirect card. If you are using only the LocalTalk port, 18 MIO NOT READY will appear every time you turn on the printer. This message will automatically disappear after 5 minutes. Note Optional Network Configuration. The following is for HP LaserJet 5Si MX printers only.
Configuring Novell NetWare Frame Type Parameters. Normally selecting a NetWare frame type is not required. The HP JetDirect card automatically selects a NetWare frame type, and only when this selection is incorrect do you have to set the NetWare frame type through the HP LaserJet 5Si MX control panel. The NetWare frame type is displayed on the self test page. To manually configure Novell NetWare parameters: 1 2 3 4 5 Table B-1 Press [Item] until CFG NOVELL=NO * appears.
Configuring TCP/IP Parameters The HP JetAdmin utility for UNIX (sold separately) may be used to configure TCP/IP parameters.
Configuring Apple EtherTalk Phase Parameter To configure EtherTalk parameters: If you do not want to configure the phase parameter, Press [On Line]. Press [Item]. CFG ETALK=NO * appears. Press [+]. CFG ETALK=YES appears. Press [Select]. CFG ETALK=YES * appears. Press [Item]. Phase=2 * appears. Press [+] to change the phase parameter. Phase=1 appears. Press [Select] to save the new value. Phase=1 * appears. Press [On Line]. You may want to configure the AppleTalk name and assign a preferred EtherTalk Zone.
Disable Network Protocols (Optional). 1 2 3 4 5 6 Press [On Line] to take the printer offline. Press [Menu] repeatedly until MIO MENU appears. Press [Item]. CFG NETWORK=NO * appears. Press [+]. CFG NETWORK=YES * appears. Press [Select]. CFG NETWORK YES * appears. Press [Item] to scroll through each network protocol. NOVELL=ON * appears. To Disable Novell NetWare: 1 Press [+] to change to NOVELL=OFF. 2 Press [Select] to save the new status. NOVELL=OFF * appears. 3 Press [Item] to continue configuring.
