General guidelines Some media might meet all of the guidelines in this manual and still not produce satisfactory results. This problem might be the result of improper handling, unacceptable temperature and humidity levels, or other variables over which Hewlett-Packard has no control.
Media that can damage the device In rare circumstances media can damage the device. Avoid the following types of media to prevent possible damage: ● Do not use media with staples or paper clips attached. ● Do not use transparencies designed for inkjet printers or other low-temperature printers. Use only transparencies that are specified for use with HP LaserJet devices. ● Do not use photo paper intended for inkjet printers.
Guidelines for using media The following sections provide guidelines and instructions for printing on transparencies, envelopes, and other special media. Guidelines and specifications are included to help you select media that optimizes print quality and avoid media that can cause jams or damage the device. Paper For best results, use conventional 80-g/m2 or 20-lb paper.
Colored paper ● Colored paper should be of the same high quality as white xerographic paper. ● Pigments used must be able to withstand the fuser temperature of 200°C (392°F) for 0.1 second without deterioration. ● Do not use paper with a colored coating that was added after the paper was produced. Custom-size media Use the main input tray for multiple sheets. CAUTION Make sure that the sheets are not stuck together before you load them.
Envelopes HP recommends that you print envelopes from the priority input tray. Envelope construction Envelope construction is critical. Envelope fold lines can vary considerably, not only between manufacturers, but also within a box from the same manufacturer. Successful printing on envelopes depends upon the quality of the envelopes. When selecting envelopes, consider the following components: ● Weight: The weight of the envelope paper should not exceed 90 g/m2 (24 lb), or jamming might result.
Envelopes with adhesive strips or flaps Envelopes with a peel-off adhesive strip or with more than one flap that folds over to seal must use adhesives compatible with the heat and pressure in the device: 200°C (392°F). The extra flaps and strips might cause wrinkling, creasing, or jams. Envelope storage Proper storage of envelopes contributes to good print quality. You should store envelopes flat. If air is trapped in an envelope, creating an air bubble, the envelope might wrinkle during printing.
Letterhead and preprinted forms Letterhead is premium paper that often has a watermark, sometimes uses cotton fiber, and is available in a wide range of colors and finishes with matching envelopes. Preprinted forms can be made of a broad spectrum of paper types ranging from recycled to premium. Many manufacturers now design these grades of paper with properties optimized for laser printing and advertise the paper as laser compatible or laser guaranteed.
Supported media weights and sizes For optimum results, use conventional 80 to 90 g/m2 (20 to 24 lb) photocopy paper. Verify that the paper is of good quality and is free of cuts, nicks, tears, spots, loose particles, dust, wrinkles, curls, and bent edges. NOTE The device supports a wide range of standard and custom sizes of print media. The capacity of trays and bins can vary depending on media weight and thickness and on environmental conditions.
Printing and storage environment Ideally, the printing and media-storage environment should be at or near room temperature, and not too dry or too humid. Remember that paper absorbs and loses moisture rapidly. Heat works with humidity to damage paper. Heat causes the moisture in paper to evaporate, while cold causes it to condense on the sheets. Heating systems and air conditioners remove most of the humidity from a room. As paper is opened and used, it loses moisture, causing streaks and smudging.

Basic functions This chapter presents a functional overview of the HP LaserJet M1005 MFP.
Basic sequence of operation The microprocessor (CPU) on the ECU controls the operation sequence of the device. The following events take place during normal device operation: Table 5-1 HP LaserJet M1005 MFP ENWW Period Purpose Remarks WAIT. After the device is turned on until Ready appears on the control-panel display. To perform the firmware initialization. Tests RAM and establishes communication with the control panel. READY. From the end of the WAIT period until the user initiates action.
Formatter system The formatter coordinates the major systems.
RAM The device contains two types of random-access memory (RAM): ● One bank of nonvolatile RAM (NVRAM) stores parameters. ● Dynamic random access memory (DRAM) provides temporary storage of the device program code along with copy, scan, and print data. Universal serial bus (USB) interface The formatter receives incoming data through its USB interface.
Device functions Device functions are divided into five groups: ● engine control ● formatter ● image formation ● laser/scanner ● pickup and feed The following figure is a block diagram of the device: To external device (host computer, etc.
NOTE In other HP LaserJet devices, the ECU and power functions are combined onto one PCA known as the controller PCA or the DC controller PCA. In the HP LaserJet M1005 MFP, the control functions are primarily relegated to the ECU PCA and the power functions to the powersupply assembly PCA.
Overcurrent/overvoltage There are two overvoltage devices in this device: ● Fuse F101 provides overcurrent protection for the fusing system circuitry. ● Fuse F102 (110 V devices only) provides overcurrent protection to the device dc power supply circuitry. You can check or replace the fuses by removing the left cover. NOTE If either of these fuses fail, replace the engine power supply. See Power supply on page 91.

6. Fusing stage—During this process, the heat and pressure fuse the toner into the media to produce a permanent image. The media passes between a heated fusing element and a soft pressure roller, which melt the toner and press it into the media. 7. Drum-cleaning stage—During this process, the cleaning blade is in contact with the surface of the drum at all times. As the drum rotates during printing, the cleaning blade wipes excess toner off the drum and stores it in the waste toner receptacle.
Figure 5-5 Device paper path Jam detection in the device The top-of-page sensor (PS801) and the paper-delivery sensor (PS803) detect media moving through the device. If a jam is detected, the ECU immediately stops the printing process and the Attention (Cancel) light illuminates on the control panel. Conditions of jam detection 54 ● Pickup delay jam—Paper does not reach the top-of-page sensor (PS801) within 1.
ENWW ● Delivery-delay jam—The paper-delivery sensor (PS803) does not detect the leading edge of media within 2.1 seconds after the top-of-page sensor (PS801) detects the leading edge. ● Wrapping jam—The paper-delivery sensor (PS803) does not detect the trailing edge of the media within 1.5 seconds after the top-of-page sensor (PS801) detects the leading edge and within ten seconds after the paper-delivery sensor (PS803) detects the leading edge.

7 Troubleshooting This chapter provides information about the following topics.
Basic troubleshooting When the device is connected to a grounded power source, the words Hewlett Packard appear with moving cursors to indicate that the firmware code is loading, and the device motor rotates for approximately 5 seconds. NOTE The flashing wavy lines that appear on the control-panel display during this period are normal. Is Power-on successful? Cause Solution No power is available because of a failed power source, cable, switch. (The control panel display is blank.) 1.
The control panel should function without error messages. Is the device ready? Cause Solution An error message appears on the control-panel display. Consult the list of common messages that appears later in this chapter, to correct the error. Control panel is not functional. Verify that the control panel cable is seated into both the control panel and the scanner formatter. Also check the connections between the scanner motor controller board and the formatter.
Initiate a scan from either the computer’s basic desktop software or from the device. Does the device scan to the computer? Cause Solution Other devices are connected to the USB port. Disconnect the other devices and try again to scan.
Control-panel messages The majority of the control-panel messages are intended to guide the user through typical operation. The control-panel messages indicate the status of the current operation, and include a page count on the second line of the display, if appropriate. When the device is receiving print data or scanning commands, control-panel messages indicate this status. In addition, alert messages, warning messages, and critical error messages indicate situations that might require some action.

Plug the device directly into the wall socket. Use the power switch to turn the device on. Scanner Error Turn off then on 52.
Solving image-quality problems If the problem occurs when printing, see Solving print image-quality problems on page 116. If the problem occurs when copying or scanning, see Solving scanning (copying) image-quality problems on page 124. NOTE Some image-quality problems can be isolated by performing device functional tests. See Functional checks on page 135. Image quality problems can also be caused by using cables that are not certified USB-Hi speed cables.
Pages do not print. Cause Solution The computer cable is loose. Check that the USB cable between the device and the computer is securely connected. The tape was not removed from the print cartridge. Remove the print cartridge, remove the tape, and reinstall the print cartridge. The print cartridge has reached end of life. Replace the print cartridge. The media does not meet HP specifications (for example, it is Make sure that the media meets specifications detailed in too moist or too rough).
Characters are only partially printed (also referred to as dropouts). Cause Solution A single sheet of paper is defective. Try reprinting the job. The print density needs to be adjusted. Adjust the print density. The moisture content of the paper is inconsistent, or the paper has moist or wet spots on the surface. Make sure that the media meets specifications detailed in the HP LaserJet Printer Family Print Media Guide. The paper was damaged by inconsistent manufacturing processes.
The printed page has a gray background. Cause Solution The priority input tray is not in place. Adjust the priority input tray. The print density setting is too high. Decrease the amount of background shading. The media basis-weight is too high. Change the media to a lower basis-weight. The humidity level is too low. Very low humidity can increase the amount of background shading. Move the device to a different location, or decrease the background shading.
The toner is loose, and it does not stay attached to the printed page. Cause Solution The inside of the device is dirty. Clean the print path. See Cleaning the device on page 36. The media does not meet HP specifications (for example, it is too moist or too rough). Make sure that the media meets specifications detailed in the HP LaserJet Printer Family Print Media Guide. The driver is not set for the correct media.
Repetitive vertical defects appear on the printed page. Cause Solution The internal parts have toner on them. If the defects occur on the back of the page, the problem will probably correct itself after a few more printed pages. Otherwise, clean the device. See Cleaning the device on page 36. The driver is not set for the correct media. In the Paper/Quality tab of the printer driver, under Type is:, select the correct media type from the drop-down list. (This affects the current print job only.
Pages are skewed (crooked). Cause Solution The media is loaded incorrectly. Reload the media, and make sure that the media guides are not too tight or too loose against the media stack. The media guides are broken or missing. Replace the media input tray or the paper-pickup assembly. See, Media input tray on page 78 or Paper-pickup assembly on page 107. The input tray is too full. Remove some of the sheets.
Large amounts of toner are scattered around the characters. Cause Solution The media resistivity is too high. 1. Use a different media. Make sure that the media meets specifications detailed in the HP LaserJet Printer Family Print Media Guide. 2. Turn the stack of media over and put it back in the tray. 3. Use media that is designed for laser printers. Vertical white stripes appear.
Solving scanning (copying) image-quality problems Use the following tables to help solve problems with scanned or copied pages. NOTE Some image-quality problems can be isolated by performing device functional tests. See Functional checks on page 135. Image quality problems can also be caused by using cables that are not certified USB-Hi speed cables. Scanning (copying) image-quality problems Pages do not print. Cause Solution The device is not plugged in, or the power switch is not on.
Parts of the page around the edges are not printing. Cause Solution The device cannot print to the edge of the paper. The device has minimum margins on each edge of 6 mm (0.25 inch). To fit the image into this printable area, slightly reduce the size of the image. If copying, the reduction setting is incorrect. Copied images will be clipped if the image on the original is too close to the edge of the original. The paper size setting is incorrect. Set the correct page size on the control-panel menu.
Copies or scanned images are too light or too dark. Cause Solution The contrast is not set correctly. 1. Adjust the contrast and resolution settings on the controlpanel menu. 2. Check that the contrast and resolution settings are correct. See the user guide for more information. The original image is very light or very dark. Adjust the resolution and contrast setting(s) on the controlpanel menu. The scanned image is too light or too dark because the original was on colored paper.
Vertically-aligned black streaks or smears appear on successive pages. Cause Solution A component is damaged. (For example, the photosensitive drum inside the print cartridge is scratched.) 1. Replace the print cartridge if it is damaged and if maintenance procedures do not improve print quality. 2. Replace the scanner assembly. See Scanner assembly on page 67. Scanned images have black dots or streaks. ENWW Cause Solution The scanner glass is dirty. Clean the flatbed glass.
Scanned text is not clear. Cause Solution The contrast, resolution, or brightness needs to be adjusted before scanning. 1. Adjust the contrast and resolution settings. 2. Check that the contrast and resolution settings are correct. See the user guide section for more information. The original is on colored paper. If the original is on colored paper, including brown recycled paper, the text might not be clear. Try adjusting the resolution, contrast, and brightness settings from the scan application.
Large amounts of toner are scattered around the characters. ENWW Cause Solution The media resistivity is too high. 1. Use a different media type. Make sure that the media meets specifications detailed in the HP LaserJet Printer Family Print Media Guide. 2. Turn the stack of media over and put it back in the tray. 3. Use media that is designed for laser printers.
Repetitive image defect ruler Use the repetitive image-defect ruler to help solve image quality problems. Place the top line on the ruler next to the first occurrence of the defect on the page. Find the mark that points to the next instance of the defect to identify the component that is causing the defect. First occurrence of print defect (0.00 inches) Print cartridge 30.8 mm (1.21 inches) Print cartridge 37.7 mm (1.48 inches) Fuser (Fixing assembly) 41.0 mm (1.61 inches) Transfer roller 46.3 mm (1.
Solving paper-feed problems Use the information in this section to solve problems that are related to moving paper or documents through the device. CAUTION Always try to remove a jam in the direction that the media feeds through the device. Jams occur in the device Occasionally, media becomes jammed during a print job. Try the following remedies before you attempt to clear the jam: ● Make sure that the media meets specifications. ● Make sure that the media is not wrinkled, folded, or damaged.
2. Grasp the handle on the print cartridge, remove the print cartridge, and set it aside. Figure 7-3 Clear a jam in the device base (2 of 3) CAUTION To prevent damage to the print cartridge, do not expose it to light any longer than necessary. Place the print cartridge in a paper bag or other opaque container until you can place it back in the device. 3. With both hands, grasp the side of the media that is most visible (this includes the middle), and carefully pull it free from the device.
Print paper-feed problems Pages are coming out curled or wrinkled. Cause Solution Paper curl is inherent to the laser printing processes, and occurs when paper is subjected to heat. Paper curl tends to relax as the paper cools while resting on a flat surface. Make sure that the media meets specifications detailed in the HP LaserJet Printer Family Print Media Guide. Remove the media, turn it over, and reload it. Paper is curled or wrinkled when printing.
The device feeds multiple sheets or jams frequently from the main input tray or priority input tray. Cause Solution Replace the pickup roller. See Device pickup roller on page 75. The separation pad is dirty or damaged. Clean the separation pad. Replace the separation pad. See Device separation pad on page 73. A sensor is not operating properly. 134 Chapter 7 Troubleshooting Check the sensors to make sure that none are jammed. If a sensor cannot be corrected, replace the sensor.
Functional checks Use the following procedures to help diagnose and solve problems that occur in the print engine. Half self-test functional check The purpose of the half self-test check is to determine which image-formation process is malfunctioning.
Figure 7-5 Check the fuser connectors on the fuser Figure 7-6 Check the fuser connectors on the power supply Drum rotation functional check The photosensitive drum, located in the print cartridge, must rotate in order for the print process to work. The photosensitive drum receives its drive from the main drive assembly.
NOTE This test is especially important if refilled print cartridges have been used. 1. Open the print-cartridge door. 2. Remove the print cartridge. 3. Mark the drive gear on the cartridge with a felt-tipped marker. Note the position of the mark. 4. Install the print cartridge and close the print-cartridge door. The startup sequence should rotate the drum enough to move the mark. 5. Open the print-cartridge door and inspect the gear that was marked in step 3. Verify that the mark moved.
To check the high-voltage connector pins The assembly has three spring-loaded pins (callout 1) to contact the print cartridge. Verify that the pins are not dirty or corroded and that the spring-loading action is functional. If the pins are dirty or obstructed, clean them using a dry cloth. If they are damaged, replace the device.
Firmware update using a flash executable file The configuration page lists the firmware version of the device. On the flash-memory-based device, update the firmware code by downloading the latest flash executable file for the device and running the program according to the readme instructions that come with it (see http://www.hp.com/support/ LJm1050. Turn the device off and then on before running the executable file.
Troubleshooting tools Use the control panel to print configuration reports and demonstration pages. The configuration report shows the settings that have been selected from the control panel. Printing a configuration report is also considered a "self test" for the device, although any of the reports can serve this purpose. A printout of the control-panel menu structure is a useful reference if you alter settings in the menu. Printing a configuration report, demonstration page, or menu structure 140 1.
Service-mode functions Use the following information to perform system-wide reset procedures and to adjust certain global settings such as the country/region. Secondary service menu Use the secondary service menu to perform various tests and print service reports. The following is a hierarchical diagram of the secondary service menu. Main menu Submenu Submenu 2ndary Service Service Reports Cont.
Adjusting the country/region code parameters Three situations can occur that necessitate changing the country/region or language settings for the device: 1. The customer has moved to a different country/region from where the device was purchased. 2. The information has been erased because of an NVRAM initialization, or the parameters are set to "undefined." 3. The formatter was replaced.
