Power service check

Step

FRU

Action

1

Power supply

If the carrier does

not

move to the left after turning the printer off and then back

on, be sure the line cord voltage to the power supply is correct and the power
supply outputs are +40 V dc at J15-1, +40 V dc at J15-2 and +5 V dc at J15-6.

If the voltages are incorrect:

• Check the internal fuse before replacing the power supply. Generally if F1 is

blown, it is due to a short-circuit in the printhead; replace the printhead and
the fuse before turning the power on again.

• Be sure the power supply cable from the power supply to the logic board is

not damaged and is correctly installed.

2

Operator panel
Operator panel cable

If there is still a Power LED problem, check the operator panel cable continuity
and replace the cable or the operator panel.

3

Carrier motor

Disconnect the carrier motor from logic board J2, and turn the printer off and
then back on. If the Power LED lights correctly only with the carrier motor
disconnected, replace the carrier motor.

4

Paper feed motor

Disconnect the paper feed motor from logic board J19, and turn the printer off
and then back on. If the Power LED lights correctly only with the paper feed
motor disconnected, replace the paper feed motor.

5

Printhead
Printhead cables

Disconnect the printhead cable from the logic board, and turn the printer on. If
the Power LED lights correctly only with the printhead cables disconnected from
the logic board, there is a short-circuit in the printhead or printhead cables.

Disconnect the printhead cable from the logic board, and be sure none of the
leads on the cable are shorted to ground.

6

Logic board

If no problem is found with the other components, but the power problem still
remains, replace the logic board and reset the bidirectional print adjustment. Go
to

“Bidirectional print adjustment” on page 4-3

.

CAUTION

Always unplug the power cord before doing any continuity measurement.
