Clearing counter
The counter indicating "current number of prints and driving time" used for the PM display function is
reset by entering "0" in it or clearing it in the PM support mode.
Notes:
Even if "0" is entered in the PM management setting value of the setting mode (08), the
corresponding counter for the PM display is not reset. Be sure to clear the counter in the PM
support mode when the maintenance is finished.
The reset condition of each counter is as follows:
• 08-6194: Current value of PM counter [process unit (K)]
• 08-6195: Current value of PM time counter [process unit (K)]
When the current value of "CLEANER/DRUM" on the main screen or "DRUM" on the sub-screen in
the PM support mode is cleared, the counter is reset.
• 08-5568: Current value of PM time counter [developer material (K)]
• 08-5569: Current value of PM time counter [developer material (K)]
When the current value of "DEVELOPER" on the main screen or "DEVELOPER" on the sub-screen
in the PM support mode is cleared, the counter is reset.
• 08-5576: Current value of PM counter [parts other than the PM parts of the process unit]
• 08-5577: Current value of PM time counter [parts other than the PM parts of the process unit]
• 08-6225: Number of output pages (Thick paper 1)
• 08-6226: Number of output pages (Thick paper 2)

• 08-6247: Counter for envelope
When the current value of "FUSER" on the main screen or "FUSER ROLLER" on the sub screen in
the PM support mode is cleared, the counter is reset.
Notes:
The following counters are cleared by executing the EPU replacement mode.
08-6194: Current value of PM counter [process unit (K)]
08-6195: Current value of PM time counter [process unit (K)]
08-5568: Current value of PM counter [developer material (K)]
08-5569: Current value of PM time counter [developer material (K)]

What sort of machine is it? Refrigerated, Ducted, Gas? To do a full reset correctly, you must switch off at the main isolator next to the unit or at the meter box and leave it off for at least 15 minutes. A quick on / off does not reset it properly. If the unit is a refrigerated split system , and the outdoor is running but the machine is not blowing cold outside and hot inside (On heating mode) It could be due to a gas leak / shortage.

Disassemble fuser unit and inspect thermistor and thermostat for dirt or damges, and heater lamp for damages.

Good luck.
