1-3-1 Paper misfeed detection
(1) Paper misfeed indication
When paper jams, the machine immediately stops operation and the occurrence of a paper jam is indicated on the copier
operation panel.
To remove the jammed paper, open the copier conveying cover.
To reset the paper misfeed detection, open and close the copier conveying cover to turn safety switch 2 off and on.

Problem Causes/check procedures Corrective measures
(1)
Paper jams when the
main switch is turned
on.
A piece of paper torn from
copy paper is caught
around the job separator
eject switch.
Defective job separator
eject switch.
Remove any found.
Run maintenance item U031 and turn the job separator eject
switch on and off manually. Replace the switch if indication of the
corresponding switch on the operation panel is not displayed in
reverse.

(2)
Paper jams in the job
separator during
copying (jam in job
separator eject
section).
Defective job separator
eject switch.
Check if the job eject pulley
or job eject roller is
deformed.
Run maintenance item U031 and turn the job separator eject
switch on and off manually. Replace the switch if indication of the
corresponding switch on the operation panel is not displayed in
reverse.
Check visually and replace the pulley if deformed.

1-3-2 Electrical problems
Problem Causes Check procedures/corrective measures
(1)
The feedshift
solenoid does not
operate.
Broken feedshift solenoid
coil.
Poor contact of the
feedshift solenoid
connector terminals.
Check for continuity across the coil. If none, replace the feedshift
solenoid.
Reinsert the connector. Also check for continuity within the
connector cable. If none, remedy or replace the cable.
Defective main PCB.
Run maintenance item U033 and check if CN35-11 and CN35-12
on the copier main PCB go low. If not, replace the main PCB.

Check and remedy.
(2)
Abnormal noise is
heard.
Check if the job eject pulley, job eject roller
and gears operate smoothly.
Grease the bushings and gears.

2-1-1 Construction of each section
The job separator consists of the components shown in Figure 2-1-1. It switches the paper path to eject copied paper to the
job separator tray.

(1) Switching the paper path
If the job separator is selected for the copy eject location, when a copy is made, the feedshift solenoid (FSSOL) turns on and
the feedshift guide of the copier operates to switch the paper path to the job separ ator . The copied paper is conv ey ed to the
job separator and then ejected to the job separator tray.
