Service Checks
Carrier Transport Service Check
FRU 1 System Board Action Unplug the printer and disconnect the carrier transport motor connector (J4) from the system board. Plug in the printer and check for approximately 12 V dc between (J4-1) and ground. If the voltage is incorrect, replace the system board. If the voltage is correct, check for carrier transport motor pins shorted to the housing. If a short is detected, replace the carrier transport motor. Check the motor for binds, or loose motor pulley. 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 carrier transport mechanism. With the carrier transport motor cable disconnected from the system board, check for zero to ten (0 - 10) ohms between the following pins on the motor: J4-1 and J4-2 J4-3 and J4-4 If the readings are incorrect, replace the motor. 3 Carrier Guide Rod Clean the carrier rod. Note: Lubricate the rod and the carrier rod bearing surfaces with grease P/N 99A0394. 4 Carrier Transport Belt Idler Pulley Parts Carrier Frame Check for worn, loose or broken parts.

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 cap to rise and seal the printhead. Carrier movement to the left uncaps the printhead. The wiper cleans the printhead nozzles as the carrier leaves the maintenance station. The wiper cleans the printhead 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 wiper to lower. Check the maintenance station for worn or broken parts. 2 Wiper Worn wipers cause degraded print quality just after a maintenance cleaning. Check for loose or worn wipers. Worn caps cause the printhead nozzles to dry and clog. Check for loose or worn caps.

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.
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 machine. 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 machine. 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 machine 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. Machine 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 machine covers when you are not working on the machine, 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.
