Service checks

Maintenance station service check

The maintenance station has two functions:

1. Cleans the printhead nozzles during the print operation.

2. When the printer is not in use, it seals the printhead to prevent
the nozzles from drying.

Parts / FRUs Action

1 Maintenance

Station Assembly

2 Wiper A worn wiper causes degraded print quality just

3 Cap A worn cap causes the printhead nozzles to dry

As the car r ie r m oves to th e le ft over the
maintenance station, a slot on the left side of the
carrier engages a tab on the sled of the
maintenance station causing the cap to rise and
seal the printhead. Car rier movement to the right
will uncap the printhead. The wiper cleans the
printhead nozzl es as the carrier leav es the
maintenance station. The wiper cleans the
printhead only when the carrier is moving to the
right. There should be no wip ing action of the
printhead nozzles when the carrier is moving to
the left. Afte r the cleani ng operat ion is complete , a

4. Rep a ir in fo r m a t i on

This chapter explains how to make adjustments to the printer and
how to remove defective parts.

CAUTION: Read the following before handling electronic parts.
When working on the printer, always unplug the printer from the
electrical outlet. High voltage is present in the power supply as long
as it is plugged into the electrical outlet.

Handling ESD-sensitive parts

Many electronic products use parts that are known to be sensitive t o
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.

• Mak e the few er po ssi b le movem ents with your body t o preven t an increase

of static electricity from clothing fibers, carpets, and furniture.

• Put th e E SD wri st strap on your w rist . C onnect the w ris t 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 pin s . If y ou are rem oving a plugga ble module , use t he 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 careful in working with ESD-sensitive parts when cold-weather heating

is used, because low humidity increases static electricity.
