Action
Check for paper jams in both the envelope feeder
and the multipurpose tray. Remove any paper.
There are no paper jam sensors in either area.
There is a printer input sensor (PS1) in the registra-
tion station.
Remove the jammed paper and POR the machine.
If you still have the error code, leave the machine
on and check PS1 at J209, pin 3 (+5V) to ground.
You should get a lower voltage reading when the
switch is activated. The switch can be accessed by
removing the EP cartridge. It is under the paper
jam station 2 guide. If the reading is incorrect,
replace PS1 (13-4). If you think you may have a
mechanical problem go to the
Paper Jams Service Check" on page
Action
Remove any paper from the fuser area.
Be sure the actuator on the top, left, rear of the
fuser is not broken.
Test PS1403 (fuser PS) by checking for voltage at
J205 pin 8 (+5V), to ground. If there is no voltage
change when the sensor is activated, replace the
switch sensor board (4-18). If you think you may
have a mechanical problem go to the
Assembly Paper Jams Service Check" on page
