Misfeed location
• The 2nd image transfer retraction position sensor is
not activated (retracted position) within a given period
of time after the retraction sequence of the 2nd trans-
fer roller has been started.
• The 2nd image transfer retraction position sensor is
not deactivated (pressed position) within a given
period of time after the pressure sequence of the 2nd
transfer roller has been started.
• The polygon motor does not rotate evenly even after
the lapse of a given period of time after it has been
started.
• The motor lock signal remains HIGH for a given
period of consecutive time while the polygon motor is
being rotated.
• The SOS signal is not detected within a given period
of time after the output of the laser has been started.
• The thermistor /1 does not detect the specified tem-
perature and the warm-up cycle is not completed
even after the lapse of a given period of time after the
cycle has been started.
• The temperature detected by the thermistor does not
reach a predetermined level even after the lapse of a
given period time after the warm-up cycle has been
started.
• The difference between the temperature detected by
thermistor/1 and that detected by thermistor/2
exceeds a predetermined value.
• The temperature detected by the thermistor /1
remains lower than the specified value for a given
period of time or longer.
• The temperature detected by the thermistor /1
remains higher than the specified value for a given
period of time or longer.
• The heater lamp remains ON for a given period of
time or longer.
• It is determined that the LED and photo receiver are
faulty through a check made when a new imaging
cartridge is detected.
• A communication error occurs in print control board
(PRCB).
• The printer determines that EEPROM is yet to be
mounted when the main power switch is turned ON.
• An undefined malfunction occurs in the engine sec-
tion (PRCB, etc.).
• Contact the responsible people of KONICA MINOLTA
when not returning in power switch OFF/ON.
• Flash ROM writing is found faulty during a check.
