Operator Codes

The following code numbers are operator instructions and
messages. In some cases, no action is required; others are
operator-correctable; and others may require service. An error code
may require up to one minute to appear. Some symptoms may not
generate an error code. Locate your symptom in the table and take
the indicated action.
Code Symptom
20 - 25 Paper Jam
When experiencing repeated or non resetable paper jam codes,
go to
26 Incorrect Paper Size
Ensure that the size of the paper being fed matches the size of
the paper selected in the paper setup menu, and the gates in the
cassette. Also check the cassette size sensing PCB and the
ejection sensing PCB. Refer to the Block Wiring Diagram Sheet.
27 Change Paper
The LCD displays the following paper sizes:
(Letter, Legal, B5, A4)
28 Load Paper
Ensure there is paper in the tray(s). If paper is present, check the
operation of the cassette paper sensor, PS301.
30 Door Open
There is only one door open switch. It is located above the LVPS.
It is a mechanical "and gate". The front door, fuser access door
and paper feed mechanism must all be closed to actuate this
switch. Remove the rear cover and EMC shield. Trace the motion
of the interlocks and repair as necessary.
31 - 34 Cartridge Missing
If all cartridges are incorrectly reported missing, check:
• The toner low detect PCB (Beam)
• The toner low detect PCB (Receiver)
• The density sensor ribbon cable
35 Cartridge Eject Handle Out
Check the mechanical operation of the cartridge eject lever. If this
is OK, check the ejection sensing PCB for damage to the ejection
sensing switch.
