Initial Issue

Status Indicator Repair Analysis Procedures

RAP 25 Malfunctioning LCD/LED

There is an erratic display on LCD/LED.

Procedure

Switch the printer power off. Remove any options connected to the System Controller PWB.
Disconnect P/J18 from the System Controller PWB. Switch the printer power on. On the Sys-
tem Controller PWB, check the following voltages between P/J18 and frame ground.

All the voltages listed in the column “with P/J18 disconnected” are correct.
Y

N
On the System Controller PWB, check the voltage on P/J13 between pins 1 and 2.  The
voltage is 3.3VDC.
Y

N
Switch the printer power off. Disconnect P/J13 from the System Controller PWB.
Switch the printer power on. Check the voltage between pins 1 and 2 on the discon-
nected plug. The voltage is 3.3VDC.
Y

N
On the LVPS, check the voltage on P/J282 between pins 1 and 2. The voltage
is 3.3VDC.
Y

N
Replace the LVPS (

REP 9.5

).

Repair or replace the harness between the LVPS and the System Controller
PWB (

PL 10.1

).

Replace the System Controller PWB (

REP 9.2

).

On the System Controller PWB, check the voltage on P/J13 between pins 3 and 4.  The
voltage is 5.0VDC.
Y

N
Switch the printer power off. Disconnect P/J13 from the System Controller PWB.
Switch the printer power on. Check the voltage between pins 3 and 4 on the discon-
nected plug. The voltage is 5.0VDC.
Y

N
On the LVPS, check the voltage between P/J PN1 pins 1 and 2. The voltage is
24.0VDC.

Y

N
Replace the LVPS (

REP 9.5

).

Replace the System Cont5.0VDC Power Supply (

REP 9.4

).

Replace the System Controller PWB (

REP 9.2

).

Switch the printer power off. Reconnect P/J18 to the System Controller PWB. Switch the
printer power on. Check the voltages between the pins listed in Table 1 and frame
ground. All the voltages listed in the column “with P/J18 connected” are correct.
Y

N
Replace the Control Panel Assembly (

PL 1.1

).

Switch the printer power off. Reinstall the removed options one at a time, switching on the
power and checking the voltages between the pins listed in Table 1 and frame ground
after each component is installed. Replace the option just installed if the voltage fails.
After all the options are reinstalled, the LCD display is still erratic.
Y

N
Problem solved. Return to 

Initial Actions
