Cleaning the Plotter To maintain the plotter in good operating condition, keep it free of dust accumulation, ink, and other contamination. Cleaning intervals are determined by the plotter environment and by the types of plotter supplies used. As with any precision electronics equipment, proper maintenance will help to ensure reliability and prolong product life. WARNING Disconnect the plotter from the power source prior to performing any maintenance.
Loading the Media The media load path begins with the entry platen, which provides a loading surface. (Illustration ' page 10Ć23.) When you assemble the plotter, it is important to correctly position the entry platen to ensure that the dashed lines exactly indicate the permitted rightĆedge loading area. The left side of the entry platen should be pressed up against the left sideĆplate. (Details ' chapter 6.) (Loading Instructions ' User's Guide, chapter 2, w Loading media.
The mediaĆnotĆloaded state can be summarized as follows: Media: not inserted or has not yet reached the primary flag Primary flag: vertical position (idle) Secondary flag: resting on plastic detector housing (idle) Optical sensor: optical path closed by both flags Drive roller: stopped Front panel: Load Media LED on Drive roller stopped Media inserted Primary flag Secondary flag Photo sensor window Media: inserted but has not yet reached the secondary

Advancing the Media The media is advanced by the media drive (XĆdrive) system. Components include: D Media motor (XĆaxis motor) D Worm pinion and helical driveĆroller gear D Drive roller (Illustration ' page 10Ć23.) The main component of the drive system is a fullĆwidth, 6.4Ćcm (2.5Ćinch) diameter roller with an elastomer skin. This roller directly drives the media and provides the surface that references the media to the printĆhead.
Providing a Force on Top of the Media The bail provides a normal force on top of the media. (Illustration page 10Ć25.) When the pinchĆwheels grip the media and the drive roller advances it, the plotter raises the bail. This enables the leading edge of the media to pass below the bail. The plotter then lowers the bail and advances the media to the overdrive roller. The star wheels on the bail are coated with a substance resistant to wet ink, so that they do not leave marks on the media.
Stretching the Media The overdrive roller stretches the media slightly as it is moved through the plotter. It thus reduces bubbling and media cockle caused by media expansion due to the absorption of waterĆbased ink into the media. Even though the geometry chosen for the plotters minimizes the occurrence of this phenomena, it still could occur on very dense plots.
Detecting the Media Edges The plotter detects the left and right media edges using the line sensor located on the carriage. The sensor is composed of D Red LED D Two lenses (caution required when handling) D Collector plate The sensor finds the left media edge when it detects the light from the red LED reflected off the media surface. The black surface of the drive roller absorbs the light. Excessive ink deposits on the driveĆroller can fool the sensor by reflecting the light.
Providing Ink (Carriage Illustration ' page 10Ć21) The plotters use two HP DeskJetĆtype cartridges, each containing 50 nozzles. The cartridges are staggered such that two nozzles on each one are not used. The main components of a cartridge are the D Plastic housing D SpringĆbag ink reservoir D Flex circuit The spring bag provides a negative pressure inside the ink supply to prevent ink from flowing out through the nozzles.
The geometry of the nozzle is important to maintain drop shape and direction. The distance of the head from the writing surface can determine image sharpness. As the distance increases, the drop shape and directionality degrade and are more difficult to predict. The two black print cartridges snap into the cartridge chutes (carriage snaps).
Producing an Image The plotters are raster based. They plot using dots to represent the data. Thus a line is made up of a series of dots. Vector B 95 C D Raster 45 14 A The resolution of a raster plotter is the number of dots per inch (dpi) it can place along one of two orthogonal axes. refers to the ability of the plotter to print a single dot at every location on a grid.
Each dot produced by a 300Ćdpi cartridge has a diameter of 0.0055 in. The dot size must be larger than 1/300th of an inch (0.0033 in.) so that when a singleĆdotĆwide line is printed, dots overlap and the line appears to be continuous. A 600Ćdpi grid contains four times as many dots as a 300Ćdpi grid. This means that four times as much ink can be laid down on a 600Ćdpi grid. Media cannot absorb that much ink effectively; it puddles, runs, and dries slowly.

Aligning the Cartridges The cartridgeĆalignment system is composed of D D D D D Stepper motor Adjustment linkage Adjustment cam Adjustable cartridge chute Carriage drive (Illustrations ' pages 10Ć15 and 10Ć21.) The following operation is used to align one cartridge with respect to the other in the XĆaxis (media axis). (YĆaxis and ZĆaxis realignments are done by varying the firing timing of each nozzle resistor.
Servicing the Cartridges (Illustration ' page 10Ć17.) Various important cartridgeĆmaintenance operations are performed at the service station: D Cartridge wiping D Cartridge capping D Nozzle spitting During operation of the cartridge, ink accumulates on the nozzle plate along with paper dust and other substances foreign to the cartridge. If not removed, this buildup can affect nozzle directionality and lead to nozzle failure.
Ink evaporates if you expose nonĆfiring nozzle plates to the open environment. Vapor loss changes the physical properties of the ink remaining in the area of the nozzle plate. The ink may form viscous plugs that fully or partially clog nozzles. To reduce the loss of ink vapor and thus prevent the nozzles from drying out when the cartridges sit idle, the service station automatically places a cap over the nozzle plates.

The vectorĆtoĆraster converter (VRC) or rasterĆtoĆraster converter (RRC), depending on the data format sent, rasterizes the data from the display list, swath by swath, and sends the swaths to a swath holding area. The swath holding area is part of the DRAM that is specially allocated for this purpose. The swath holding area is large enough to hold up to three swaths at a time.
Plotter Architecture The plotters have the multiprocessor architecture shown in the following diagram: Main Processor (80960KA) Internal Memory (ROM/RAM) Expansion Memory (SIMM DRAM) I/O (Centronics) (RS–232) 80960 bus Encoders Shuffler ASIC Swath RAM (256 KB) Support ASIC Motor Drivers Nozzle Timing ASIC Carriage Processor (8051) Servo Processor (8052) EEPROM (256) Cartridge Drivers Sensors Line Detector Front Panel Plotter Architecture The plotter electronics, besides sensors and cables,
Main PCA (Part illustration ' page 10Ć9.
The main processor system consists of the following: Main processor (80960) ROM Processor support ASIC Shuffler ASIC with swath memory Input/output interfaces DRAM To Servo Processor System 80960 CPU Demultiplexed Bus Interface Processor Support ASIC RS-232 Interface Swath RAM Shuffler ASIC To Carriage Processor System DRAM SIMM Socket Centronics Interface 4x8-Mbit ROM 2-MB DRAM Main-Processor-System The main processor interprets graphicsĆlanguage com
The processor support ASIC provides support for the main processor, and an interface between the main processor and the servo processor. The shuffler ASIC and the swath memory shuffle the rowĆoriented image data in the system memory into columnĆoriented nozzle data needed by the print cartridges.
The main processor controls the DTR (Data Terminal Ready) signal using a bit in the parallel I/O control register. Whenever the power to the plotter is on, RTS (Request To Send) is set active. No other modem signals are controlled or monitored. The reset state of the DTR signal is undefined. During initialization, the main processor first sets the DTR control bit to 1, which signals the host that the interface cannot accept data.
The servo processor system consists of the following: Servo processor (8052) Processor support ASIC FrontĆpanel interface StepperĆmotor driver CarriageĆprocessor interface Various sensor inputs EEROM Motor Position Encoders To Main Processor System Front-Panel Interface Sensors 8052 Servo Processor Processor Support ASIC Stepper-Motor Driver Motor Drivers EEROM To Carriage Processor System Servo Processor System The servo processor controls all of the plo
The front panel consists of nine LEDs and eight switches. The servo processor interface to the front panel consists of nine control signals and two sense signals. The servo processor controls a stepper motor used for printĆcartridge servicing and alignment. The servoĆprocessor serial port is used to communicate with the carriage processor.
The following are the power components on the main PCA: Two motor driver ICs and heatsinks. To regulate the amount of energy given to the printĆcartridge heating resistors, a precise voltage regulator controls the printĆcartridge voltage supply. The regulator power device is located on the main PCA, but the cartridge resistors and drivers are located on the carriage PCA.
Carriage PCA The carriage PCA has four main functions: The nozzleĆtiming ASIC controls the firing of the print cartridges, using data from the shuffler ASIC on the main PCA. A linear encoder senses the carriage position. A line sensor enables automatic printĆcartridge calibration. A thermistor monitors the temperature near the print cartridges. The carriage PCA is installed in the carriage assembly, componentĆside down to accommodate the operation of the linear encoder.
The carriage processor dedicates its address/data bus to interface with the nozzleĆtiming ASIC. The ASIC is also connected to the shuffler ASIC by a synchronous serial channel. The nozzleĆtiming ASIC applies the shuffled data it receives from the shuffler ASIC to the cartridge drivers, controlling the firing time and sequence of the printĆcartridge nozzles. The outputs controlling the print cartridge drivers are disabled while the reset signal is active.
Front Panel PCA The plotters use the same frontĆpanel PCA as the DeskJet 550. The frontĆpanel consists of nine LEDs and eight switches, mounted on the PCA, which is deeply recessed behind a plastic housing containing the key pad. The keys act on the switches through push rods. Light pipes transmit the light from the LEDs to the display area. The LEDs are driven by drivers on the main board, under the control of the servo processor.
Power Supply An autoĆranging power supply is located in the electronics enclosure. It accepts and automatically adjusts to an ac input of 90 V through 264 V and produces regulated voltages of +5 V, +12 V and -12 V, and an unregulated +24 V. These voltages are used as follows: Voltage Use +24 V Motor drivers and voltage regulator on the main PCA. (Regulated +20 V for cartridge circuits on the carriage PCA). +12 V Fan power and RS-232 driver. –12 V RS-232 driver. +5 V IC power and sensors.

FrontĆPanel Keys in Service Mode Pressing any single frontĆpanel key in service mode performs the same operation as in normal mode. However, in service mode, you can also use combinations of keys, to perform the various service tests and calibrations. With this intent, the Replot key acts as a SHIFT key, and the Cancel key acts as an ALT key. The following illustration indicates which service tests and calibrations are assigned to which frontĆpanel keys.
Cartridge Alignment When to Align Cartridges If you suspect that the plotter is not producing plots of the highest quality, you can run a simple cartridgeĆalignment routine that will ensure that the print cartridges are aligned. Perform this routine also after clearing a media jam. The alignment is also automatically performed after each time you replace or reseat the print cartridges. In this case, the plotter uses the first sheet of media that you load to perform the alignment.
Gap } } Left cartridge Right cartridge If any of the leftĆcartridge or rightĆcartridge lines includes gaps, then the corresponding print cartridge should be either cleaned or replaced as appropriate.
Accuracy Calibration Purpose The accuracy calibration procedure is used to correct the endĆpoint accuracy of the media axis. The cartridge axis does not require calibration and is used to calibrate the media axis.
Performing the Accuracy Calibration , Enter service mode page 7Ć2. . Plot a service configuration plot page 8Ć23. A Measure the distance between the centers of the X" marks on the configuration plot. An accuracy calibration is needed if this distance is not 500 mm (20 in) 1 mm (0.04 in) under normal environmental conditions. If the measured accuracy, media thickness, or environmental conditions vary greatly from the factory standards, recalibrate the plotter by continuing with the following steps.
When the Ready LED lights up, hold down the SHIFT key and press Accuracy Calib. Read, SHIFT The Busy LED lights up. The plotter takes about 3 minutes to read the calibration sheet, to calculate the calibration data, and to save the data in the EEROM. During this time, the plotter appears almost motionless for short intervals. The plotter then ejects the sheet. Accuracy Calib. Read Unload the sheet. Bail Calibration In this procedure, the `up' position of the bail assembly is calibrated.
MediaĆSensor Calibration The mediaĆsensor calibration measures the position of the mediaĆsensor levers with respect to the drive roller. A value is stored in the EEROM when the procedure is completed. Perform the mediaĆsensor calibration whenever: D D D D The EEROM is cleared The main PCA is replaced The media sensor is removed or replaced The leading and trailing margins of a plot are greater than 17 mm (0.67 in).
SetupĆSheet Calibration This calibration calibrates the power of the LED situated on the cartridge carriage, for better scanning of the setup sheet. Perform the setupĆsheet calibration whenever: D D D D The EEROM is cleared The cartridge carriage is replaced The optical sensor on the cartridge carriage is replaced Problems frequently occur with setupĆsheet scanning To calibrate the LED, perform the following procedure: Enter service mode D page 7Ć2. Load a blank sheet of paper.
8 Troubleshooting 8Ć0
Power On The plotters automatically perform a series of internal self tests and mechanical initialization sequences whenever the user switches the plotter on. These are completed after about 30 seconds. If a failure occurs, an error is indicated on the frontĆpanel LEDs. You can perform a failure analysis by interpreting the LED error code. (Details later in this chapter.) PowerĆOn Self Test The powerĆon self test does the following: 1 Initializes the servo processor. 2 Initializes the main processor .
Extended PowerĆOn Self Test Perform the extended powerĆon test whenever the plotter passes the normal powerĆon test, but does not function properly. To begin the extended powerĆon test, perform the following procedure: , Switch the plotter off. Access Cartridges . While holding the Access Cartridges key down, switch the plotter on. A Once the Busy LED lights up, release the Access Cartridges key.
What You Should See and Hear When you turn on the plotter, the following happens: 1 All six LEDs light up for a brief moment; then the Busy LED remains on. Busy 2 The stepper motor makes a buzzing noise. 3 The cartridge carriage knocks against the leftĆhand side. 4 The carriage moves across the plotter and knocks three times against the rightĆhand side. 5 The carriage returns to the leftĆhand side.
Errors Indicated by LEDs Error The Error LED on the front panel works in combination with the other LEDs to specify the type of error that has occurred. The three possible states of any LED are represented like this: Off On Flashing User errors are associated with user settings or user actions and may be solved by the user without calling a Customer Engineer. They are indicated by the Error LED flashing. (Further Information D User's Guide, chapter 4, .
Error and Busy flashing Error Busy Possible Causes Corrective Action The serialĆinterface settings are different on the plotter and on the software. 1. Print a setup sheet and check the plotter's current settings for Baud Rate and Parity. 2. Compare these with the current settings of the same two items for your application software. They must be the same. 3. If necessary, change the plotter's settings. The serialĆinterface cable is not correctly connected. Connect the cable correctly.
System errors are associated with plotter hardware failure that needs to be repaired by a Service or Customer Engineer. System errors are indicated by the LED lit and steady. represents the frontĆpanel In the tables on the following pages, the symbol LEDs, where, in this case, the Error, Paper and Ready LEDs are lit and steady, and the other LEDs are off.

If no service note deals with this error, report the problem to the HP Response Center. 28.Communication failure between the main and servo processors. Communication occurs through the processorĆsupport ASIC.
FirmwareĆCode Revision Level To check the firmwareĆcode revision level that the plotter is using, print a setup sheet or a service configuration plot. Troubleshooting Tips Repair + Calibrate After you have made a repair, consider if any calibrations have been affected. Print Quality You can use the user demonstration plot to look at overall print quality including smoothness and straightness of lines, arcs, circles, and characters.
Servo ControlĆSystem Failures MediaĆAxis (XĆAxis) Shutdown In the case of a mediaĆaxis shutdown, try one or more of the following corrective actions: D Clear any binding in the mediaĆaxis mechanics due to a media jam. (Do not pull the media along the carriage axis. Doing so could break the mediaĆsensor flags.) D Remove the two screws that attach the driveĆroller gear to the drive roller. This should enable you to manually spin the drive roller. If it does not, the roller is probably jammed.
Misaligned Cartridge Caps If a customer is complaining about shortened cartridge life or frequent cartridge failure, you should check the cartridgeĆcap alignment (procedure below). This is especially true if the problem is always happening to the same cartridge. A sure sign of a misaligned cap is excess ink around the cap and inside the ink reservoir. You should clean the caps and reservoir using only water. You should also clean the wiper.
BailĆLiftĆMechanism Failure Normal BailĆLift Sequence The following is what should happen during a normal bailĆlift sequence: , The cartridge carriage positions over the engagement lever. This connects the autoĆlift mechanism to the driveĆroller gear. The media motor becomes the driving force for the autoĆlift. . The media motor drives the drive roller, which in turn drives the bail autoĆlift. The bail begins raising up until the UP" position is reached.
Cartridge Carriage Rubbing against Encoder Strip When properly installed, the encoder strip should pass through the cartridgeĆcarriage assembly without touching it. Sometimes excessive rubbing may be experienced, causing the encoder strip to buckle or vibrate, and thus causing errors in the carriageĆaxis servo feedback system and poor carriageĆaxis position tracking. You can adjust the encoderĆstrip position by adjusting the position of the encoder spring bracket.
Ink Smearing Add Starwheel Mount Ink may smear in DesignJet 200 plotters and early DesignJet 220 plotters due to cockle in the media caused by the geometry of the media path. The problem is more evident when loading A/A4Ćsize media. (Solution D chapter 9, w Change in Bail and Overdrive Parts.) Change Carriage Rear Bushing Another reason for ink smearing in DesignJet 200 plotters is an insufficient distance between the cartridges and the media.
Plotter won't Read Setup Sheet; Plots Solid Black Area Fill This problem can occur on DesignJet 200 plotters with the oldĆstyle cartridge carriage. Install a new carriage. (Details D chapter 9, w .) Problems in Loading Media User's Guide The Troubleshooting section of the User's Guide lists mistakes you may be making if the plotter continually rejects your media.

ReĆinstalling Teflon Washers Normally, you should not have to reĆinstall teflon washers on a DesignJet 200. Instead, you should install a camĆgear support and the associated parts as described later in this chapter. The following note is given in case you need to reassemble the plotter while you wait for these parts to arrive. Problems can occur if the bailĆlift mechanism is too loose or too tight. Typically the number of teflon washers to install is two.
