Maintenance station service check
The maintenance station has three functions: 1. Wipes the printhead nozzles to clean them of dirt. 2. Provides a place for printheads to fire all nozzles, keeping them clear prior to printing. 3. 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. Do not wipe 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. Replace if needed. Go to the "Maintenance station removal" on page 4-17. 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.

3. Diagnostic aids
Theory of mechanism
Scanner mechanism
The scanner mechanism consists of components which feed, scan, and eject the documents that are to be copied or transmitted to a remote facsimile unit. These components and their functions are explained below.
Drive feed roller assembly
The drive feed roller assembly, consisting of various rollers, rubber pad, and springs, automatically separates and feeds the pages of a document over the scanning area and stacks them on the document exit tray. Documents up to 15 pages can be placed in the drive feed roller assembly for scanning. The leading edge of the document moves the document detect sensor lever when the operator slides the stack into the drive feed roller assembly. The scan motor starts to rotate when the document detect sensor detects the leading edge of the document. The roller feeds the first page of the document into the feeder. The scan motor stops when the leading edge of the page actuates the document scan sensor. The page is now in the scan position. The drive feed roller assembly rubber pad prevents multiple sheets from being fed. A spring provides force that the pad places on the document pages for proper separation. The scan motor is turned on when the machine is ready to scan the document and drives the feed roller at a speed determined by the resolution selected. The scan motor stops after a set period of time when the trailing edge of the page releases the document scan sensor. If another page is detected as the trailing edge of the page releases the document scan sensor, the next page feeds to the scan position. The exit roller pushes the page out onto the document exit tray where it is stacked.
Diagnostic aids 3-1
4413-XXX
Contact Image Sensor (CIS)
The contact image sensor unit consist of LEDs, rod lens array, and a photo sensor. The LEDs illuminate the document to be scanned when the leading edge is detected by the document scan sensor. The LEDs turn off when the document exits the scanner mechanism. The LEDs illuminate the document to obtain an image from the document through the rod lens array, where the image is translated into voltage levels.
Document sensors
There are two document sensors in the scanner mechanism; the document detect and the document scan sensor. The document detect sensor, detects whether or not a document is loaded, and the document scan sensor detects the scan position of the document. The scanner mechanism consists of components which feed, scan, and eject the documents that are to be copied or transmitted to a remote facsimile unit.

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; 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 ESDsensitive 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. Repair information 4-1

Removals
General precautions on removals
When you disassemble and reassemble components, use extreme caution. The close proximity of cables to moving parts makes proper routing a must. If components are removed or replaced, any cables disturbed must be replaced as close as possible to their original positions. Before removing any component from the machine, note the cable routing. When servicing the machine:
· · · · · · ·
Check to verify that documents are not stored in memory. Move the printer cartridge to far right to cap the nozzle. Unplug the power cord. Use a flat and clean surface. Replace only with authorized components. Do not force plastic-material components. Make sure all components are in their proper position.
