Engine Non-startup Mode
This mode is to start-up the machine without using the engine. When the error related to
the engine occurs, you can ignore the error and get the error history or the other counter
information though it is impossible to print. When the machine doesn’t work in case that
the connection failure between the Main controller and the Engine controller occurs, it is
possible to update the Main controller itself to recover from the failures.
Drum Unit Cleaning Mode
This mode is to remove the dust attached on the exposure drum. When white spots
appear on the printout, perform this operation to remove the dust by using the drum
cleaning sheet.
<Operating Procedure>

at the same time.

PLEASE WAIT” appears on the LCD during cleaning.
(4) When finishing cleaning normally, “DRUM CLEANING/ COMPLETE” appears on the
LCD.
