8 Warm-Up Failure RAP
WARNING
Switch off the electricity to the machine. Disconnect the power cord from the customer supply
while performing tasks that do not need electricity. Electricity can cause death or injury. Moving
parts can cause injury.
Description
• The machine fails to warm up.
• The voltage of the thermistor remains low for a predetermined period of time when a warm-up
cycle is started.
• The temperature detected by the thermistor remains lower than a reference value for a prede-
termined period of time for the period of time that begins 5 sec after, and ends 9 sec after, the
start of the warm-up cycle (where the temperature detected by the thermistor is 80°C/176°F
or less).
• The temperature detected by the Thermistor does not increase for a 3-sec period or more for
the period of time that begins after the lapse of a predetermined period of time after the fuser
roll heat lamp has been turned ON and ends when the lamp is turned OFF.
• The fuser roll heat lamp remains ON for a 30-sec period or more (except during the period
through which the Main Motor remains energized).
Table 7: Warm-Up Failure
Checks and Causes Solutions
1. Check the thermistor as its voltage might
remain low during the warm-up cycle.
1. Install a new fuser (PL 10).
2. Install a new Main PBA (PL 5).
3. Install a new LVPS (PL 11).
2. Check the thermostat.
3. Check the fuser.
