Probable Cause
CLEAN UP SCANNER
In the scanning compensation data list printed by the mainte-
nance-mode function code 05 (refer to Chapter V, Section 3.2),
less than fifty percent of the white level data is faulty.
(This message may appear only in the maintenance mode.)
COOLING DOWN
The controller, which monitors the internal resistance of the in-
casing temperature sensor (thermistor) and heater thermistor,
has detected that the temperature inside the machine or the
heater temperature exceeded the specified level. If either
temperature exceeds the preset level, recording is no longer
possible.
COVER OPEN
The cover sensor detects that the front cover is not closed.
DOCUMENT JAM
n
Document jam
(1) The document length exceeds the limitation (400 or 90 cm)
registered by firmware switch WSW16. (Refer to Chapter V,
Section 3.5.)
(Both the document front and rear sensors stay ON after the
document has been fed by the registered length.)
(2) The document rear sensor detects no trailing edge of a
document after the document has been fed by 400 cm.
(The document rear sensor stays ON even after the
document has been fed when the document front and rear
sensors were OFF and ON, respectively.)
n
Document loading error
(1) The document rear sensor detects no leading edge of a
document within 10 seconds from the start of document
loading operation.
(The document rear sensor stays OFF even after the
document has been fed when the document front sensor
was ON.)
(2) The loaded document is too short.
(Since the document is shorter than the distance between
the document front and rear sensors, the document front
sensor is turned OFF before the document rear sensor is
turned ON.)
MACHINE ERROR XX
"XX" indicates an error code. Refer to [ 2 ] on pages VI-4 and
VI-5.
PLS CLEAN DRUM
In either of the following cases, this message appears,
prompting the user to clean the corona wire of the laser-
sensitive drum.
- When the specified number of pages has been printed after
the replacement of the laser-sensitive drum.
- When the corona wire abnormally emits ions. (This happens
if the corona wire becomes dirty, superimposing noise
components on toner sensor signals.)
