Operation
9.3.1
IU life control
• Each IU has EEPROM board that detects a new IU and keeps track of the service life of
the IU.
A. New IU detection control
• New IU detection control is activated under the following conditions
While the front door is closed, the main and sub power switch is turned ON.
The front door is opened and closed during normal operation.
The machine is reactivating from the sleep mode.
B. Operation after a new IU detection
• When a new IU is detected, an automatic adjustment is made of TCR sensors.
C. When life is reached
• The IU life counter is used to keep track of IU life.
• When the life value is reached, a warning screen appears to prompt the user to replace
the imaging unit.
• After the life value is reached, when a predetermined number of pages is printed, the
machine stops printing and displays IU replacement screen to request the unit replace-
ment.
D. Warning screen display
• The warning screen display that appears when the IU life value is reached can be
changed in Consumable life reminder in the service mode.
• When Consumable life reminder is set to YES, the full-screen message that requests IU
replacement is displayed when the life value is reached.
• When Consumable life reminder is set to NO, the message that requests IU replacement
is displayed when the life value is reached.
