m.
Plug in the I/O board connector ('P' / J800) in the electronics module. This
step adds the I/O board and control panel to the electronics module.
n.
Turn on power to the system.
o.
If the electronics module, I/O board and control panel are working, the error
code 34,001.43 should be displayed on the LCD to indicate the printhead is
disconnected.
p.
If the correct error code is not displayed, replace the control panel and I/O
board and verify the correct error code appears on the LCD. Retest
electronics module, I/O board, control panel combination.
q.
If the correct error code is displayed, continue with the next steps of the
procedure.
r.
If no error code is displayed, return the original control panel and I/O board
to the system, replace the electronics module and then continue with the next
steps of the procedure.
s.
If a different error code is displayed, see the "Fault Code Error Message
Troubleshooting" on page 3-8 for a definition of the problem and the
procedures needed to solve the problem.
2.
Repeat the following procedures to check all circuits connected to the I/O board:
a.
Turn off system and wait 30 seconds for power supply capacitors to
discharge.
b.
Plug in the following connectors, one at a time, and perform steps C and D
for each connector.
c.
Turn on system and wait for the error code 34,001.43. Check that the three
voltage indication LEDs INSIDE the electronics module (visible through the
vent holes of the electronics module near the AC power switch) are lit.
d.
If the proper error code and LED doesn't appear after each I/O connector is
reconnected, repair or replace the faulty circuit.
e.
If the proper code appears, repeat the procedures until all I/O board
connectors are plugged back in.
f.
If repairs are made during this step, plug in all connectors to system and
retest. If system is fixed, reattach covers to system and perform a full test. If
no defects are found in this step, continue with next step.
3.
The proper error code is displayed, repeat the following procedures to check all
circuits connected to the electronics module:

for each connector.
c.
Turn on system and wait for the error code 34,001.43. Check that the three
voltage indication LEDs INSIDE the electronics module (visible through the
vent holes of the electronics module near the AC power switch) are lit.
d.
If the proper error code and LED doesn't appear after each I/O connector is
reconnected, repair or replace the faulty circuit.
e.
If the proper code appears, repeat the procedures until all I/O board
connectors are plugged back in.
