Recovery and Cleaning Routines
Recovery Routine
The Recovery Routine allows the printer to return to normal operation after a
print cycle interruption. The routine switches ON the main motor and signals the
HVPS to switch ON CR (DC) and TR (AC) voltages.
The printer uses the Recovery Routine after the following interruptions:
• Interlock Switch deactuation
• Paper Cassette removal
• Exit Sensor acuation
The printer does not perform the Recover Routine if either the Exit Sensor or the
Registration Sensor are actuated when you actuate the Interlock Switch, install
the Paper Cassette, or switch ON the power.
Cleaning Routine
The printer starts the Cleaning Routine when power is switched ON, when the
CRU Switch is switched ON, and between printing cycles (except during
continuous printing).
During the cleaning routine, the Main Motor and HVPS are ON.
There are two types of Cleaning Routines:
Warm-up cleaning Starts whe the main power or CRU switch are switched on. Warm-up cleaning
works only in ESS (Controller) Mode . The printer is READY when the Warm-up
cleaning is finished and the fuser is at operating temperature.
Cycle-out cleaning Starts at the end of each print cycle.
You can stop the Cleaning Routine by deactivating the Interlock Switch,
removing the Paper Cassette, or actuating the Exit Sensor. To restart the
Cleaning Routine, activate the Interlock Switch, replace the Paper Cassette, or
deactivate the Exit Sensor.
