cartridge has a total of 208 nozzles and installs on the left. The color
cartridge has a total of 192 nozzles and installs on the right. The
printer is capable of printing in two directions from either cartridge.
Power Consumption
• 13 Watts - Idle Mode (power on - not printing)
• 21 Watts - Printing (average)
Maintenance Approach
The diagnostic information in this manual leads you to the correct
field replaceable unit (FRU) or part. Use the error indicator charts,
symptom index, service checks, and diagnostic aids to determine
the symptom and repair the failure.
This printer can be serviced without being connected to a host
computer. The user is directed, in the Printer Control program, to
perform the head to head and bidirectional alignment adjustments
after replacing a print cartridge.
After you complete the repair, perform tests as needed to verify the
repair.

Test on the Diagnost ic Menu when a problem is suspected either
with the hard disk adapter board or with the hard disk.
Note: The Quick Disk Test is a non-destructive test and indicates
Pass or Fail. If the test fails, replace the hard disk, refer to the

Paper Lifters Operation Theory
As the carrier applies pressure against the clutch lever, located in
the gear box assembly, the left and right paper lifters engage,
positioning the media into the printer. Media is then pulled through
the printer by the combination of torque action between the paper
feed motor and the large feed roller, and friction between the paper
feed motor and the media.

4. Repa ir Informa t i on
This chapter explains how to make adjustments to the printer and
how to remove defective parts.
Note: Read the following before handling electronic part s. 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 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 st r ap on you r w ris t. C on nect the wris t b and 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 pluggable module, use the correct too l .
• 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.
