2. Diagnostic Information
Use the error indicator table, symptom tables, service checks, and diagnostic aids to determine the failing part.
Start
Service error indications show as a series of flashes of the Power light. There is a pause between each series of flashes. If your printer has an error indication, locate the series of flashes in the "Error Indicator Table" on page 2-2 and take the indicated action. Unplug the printer to clear the error indicator. If an error indicator appears, go to the error indicator table and take the indicated action for that error. The printer also logs the last occurring error. If you think it may have an intermittent error, or the error indicator lights have been cleared, you can retrieve the error: 1. Run the "Print NVRAM Contents" on page 3-6. The last error appears at the bottom of the page. 2. Run "Initialize Error Log" on page 3-3 to clear the error (the error may not be the result of a current error). 3. Run the "Test Page" on page 3-7. If no error appears, go to "Power-On Self Test (POST) Sequence" on page 2-2.

Maintenance Station Service Check
The maintenance station has two functions: 1. Cleans the printhead nozzles during the print operation. 2. Seals the printhead when it is not being used to prevent the nozzles from drying.
FRU 1 Maintenance Station Assembly Action As the carrier moves to the right over the maintenance station, a slot on the bottom of the carrier engages a tab on the sled of the maintenance station causing the caps to rise and seal the printheads. Carrier movement to the left will uncap the printheads. The wipers clean the printhead nozzles as the carrier leaves the maintenance station. The wipers clean the printheads only when the carrier is moving to the left. There should be no wiping action of the printhead nozzles when the carrier is moving to the right. After the cleaning operation is complete, a tab on the maintenance station engages a tab on the carrier, causing the wipers to lower. Check the maintenance station for worn or broken parts. 2 Wiper A worn wiper causes degraded print quality just after a maintenance cleaning. Check for loose or worn wiper. A worn cap causes the printhead nozzles to dry and clog. Check for loose or worn cap.

Paper Feed Service Check
If your printer does not have paper jam problems, continue with the service check. If your printer does have a paper jam problem, examine it for the following before you begin the service check:
· · · ·
Check the entire paper path for obstructions. Be sure there is not too much paper in the sheet feeder. Be sure the correct type of paper is being used. Check for static in the paper.
FRU 1 System Board
Action With J5 disconnected and power on, check for +30 V dc between J5-1 and ground, and between J5-3 and ground on the system board. If the voltage is not present, check for motor pins shorted to the motor housing. If you find a shorted pin, replace the motor. If you still have a failure after replacing the motor, replace the system board.
2-8
4092
FRU 2 Paper Feed Motor Action A noisy or chattering motor or a motor that fails to turn, can be caused by: · An open or short in the motor · An open or short in the motor driver on the system board · A bind in the paper feed mechanism With the paper feed motor cable disconnected from the system board, check for 5 to 10 ohms between pin 1 and 4 on the motor cable. If the reading is incorrect, replace the motor. Check for motor pins shorted to the motor housing. If you find a shorted pin, replace the motor. If the failure remains, replace the system board. Although the paper feeds in a forward direction only, the paper feed motor turns in two directions. If the paper feed motor turns in one direction only, replace the system board. Binds in the paper feed motor or gear train can cause intermittent false paper jam errors. Remove the paper feed motor and check the shaft for binds. Also check for loose or worn motor gear. 3 Gears Check for binds in the gear train and paper feed mechanism by rotating the large feed roll by hand. If you notice a bind, isolate it by removing one of the small idler gears on the inside of the left side frame. Replace any worn or binding gears or rollers. At the beginning of the paper feed operation, the paper feed motor reverses momentarily to allow the feed arm pawl to drop off the home position notch in the left side frame. If the pawl fails to drop off the notch, check the feed arm assembly for binds, and worn or broken parts. Perform the "Paper Path Service Check" on page 2-10, starting at Step 1.

FRU 3 System Board Printhead Cable Rubber Backer Thermal Sensor Action · Perform the "Test Page" on page 3-7. Look for a break in the diagonal line of the test pattern. A broken line indicates one or more print nozzles are not working. Run the test again to verify the failure. If there are even breaks in the diagonal line similar to the pattern shown below, replace the system board.
If there is a single break or random breaks in the diagonal line check the following: · Check the gold-plated contacts, on the end of the cable that connect to the carrier, for dirt and wear. Use only a clean dry cloth to clean the contacts. Also check the cable for damage. You may need to remove the cable from the carrier to inspect it. · A worn rubber backer results in poor contact between the printhead cable and the print cartridge. Check the rubber backer for wear. · Refer to the test page. The temperature value in Celsius, or the message "Thermal Sensor Not Installed" is printed. If the thermal sensor is not installed or malfunctioning, and the printer is operating in a warm environment > 104F (40C), excessive ink may flow from the cartridge. Be sure the thermal sensor is connected to J7 on the system board. If the thermal sensor is connected and a "Thermal Sensor Not Installed" message prints, replace the thermal sensor. Note: Printing slows to prevent overheating and excessive ink flow, when the temperature is above the normal operating range, or when printing complex graphics. The normal operating temperature range is 60 F to 90 F (16 C to 32 C). 4 Maintenance Station Intermittent nozzle failures can be caused by worn parts in the maintenance station.

4. Repair Information
This chapter explains how to make adjustments to the printer and how to remove defective parts. Note: Read the following before handling electronic parts. When working on the printer, always unplug the printer from the wall outlet. High voltage is present in the power supply as long as it is plugged into the wall outlet.
Handling ESD-Sensitive Parts
Many electronic products use parts that are known to be sensitive to electrostatic discharge (ESD). To prevent damage to ESD-sensitive parts, follow the instructions below in addition to all the usual precautions, such as turning off power before removing logic boards:
· · · · · · · · ·
Keep the ESD-sensitive part in its original shipping container (a special "ESD bag") until you are ready to install the part into the printer. Make the least-possible movements with your body to prevent an increase of static electricity from clothing fibers, carpets, and furniture. Put the ESD wrist strap on your wrist. Connect the wrist band to the system ground point. This discharges any static electricity in your body to the printer. Hold the ESD-sensitive part by its edge connector shroud (cover); do not touch its pins. If you are removing a pluggable module, use the correct tool. Do not place the ESD-sensitive part on the printer cover or on a metal table; if you need to put down the ESD-sensitive part for any reason, first put it into its special bag. Printer covers and metal tables are electrical grounds. They increase the risk of damage because they make a discharge path from your body through the ESD-sensitive part. (Large metal objects can be discharge paths without being grounded.) Prevent ESD-sensitive parts from being accidentally touched by other personnel. Install printer covers when you are not working on the printer, and do not put unprotected ESD-sensitive parts on a table. If possible, keep all ESD-sensitive parts in a grounded metal cabinet (case). Be extra careful in working with ESD-sensitive parts when cold weather heating is used because low humidity increases static electricity.
