14. MALFUNCTION CODE
14.1 Trouble code
•The copier’s CPU performs a self-diagnostics function that, on detecting a malfunction,
gives the corresponding malfunction code and maintenance call mark on the control
panel.
14.1.1 Trouble code list
A0XXF4E502DA
Code Item Description
C0211 Bypass tray lift-up failure • When a print cycle is completed, a jam is fixed, or the
power switch is turned ON, if the bypass lift sensor (PS4)
does not change from the unblocked to blocked condition
after the lapse of a given period of time after the bypass
pick-up solenoid (SD1) is turned ON, the machine retries
the depressing motion.
This trouble code is displayed if the PS4 is not blocked
after the retry.
• While the bypass lift sensor (PS4) is blocked, if the PS4 is
not unblocked after the lapse of a given period of time after
the bypass pick-up solenoid (SD1) is turned ON, the
machine retries the lifting motion.
This trouble code is displayed if the PS4 is not unblocked
after the retry.
C2351 Suction fan motor
malfunction
• The fan lock signal remains HIGH for a predetermined con-
tinuous period of time while the motor remains stationary.
C2557 Abnormally low T/C ratio • The T/C ratios detected by the TCR sensor board (TCRSB)
are below the threshold for the detection of abnormally low
T/C ratio for three successive times.
However, if a toner empty condition is detected, this abnor-
mality is not detected.
C2558 Abnormally high T/C ratio • The T/C ratios detected by the TCR sensor board (TCRSB)
are above the threshold for the detection of abnormally
high T/C ratio for three successive times.
•The connector between TCRSB to PRCC is disconnected.
C255C TCR sensor adjustment
failure
•When [SERVICE MODE]→[FUNCTION]→[TCR AUTO
ADJUST] is performed, the difference between the TCR
sensor output voltage determined by TCR AUTO ADJUST
and the standard voltage is greater than the given value.
C2702 Abnormal image transfer
voltage
•The image transfer voltage remains more than 100 V con-
tinuously for a given period of time while the drum remains
stationary.
