2. Cleaner solenoid ON/OFF timing
NOTE:The top edge of the image in the 2UP mode is defined as the
top edge of the first page on the IBT 1 surface.
(a) Normal cleaning
Table 2-13. Normal Cleaning On/Off Timing
ON timing Comes ON G1 second before the top edge of the image
(printed area) on the IBT surface after the 2nd transfer
advances to the position where the Belt cleaner assembly
cleans the belt.
OFF timing Goes from ON to OFF G2 seconds before the top edge of
the next image (printed area) on the IBT surface advances
to the position where the Belt cleaner assembly cleans the
belt.
NOTE:The time specified above only applies to the standard
speed mode. The time required for the half speed mode will be
doubled.
NOTE:If there is not sufficient time for the Cleaner Cam
Solenoid to switch from OFF to ON—because there is not
enough time between the bottom edge of the previous image
and the top edge of the next image (for example, in a continuous
printing in the standard speed mode or B/W mode)—the Cleaner
Cam Solenoid stays ON and the Belt Cleaner Assembly
continues to be in the advanced condition.
NOTE:The time required for the Belt Cleaner Assembly advance
operation is 1.0 seconds (standard speed mode) and 2.1
seconds (half-speed mode) since the Belt Cleaner Assembly
receives the Cleaner Cam Solenoid ON signal. The time
required for the Belt Cleaner Assembly retract operation is 0.9
seconds (standard speed mode) and 1.8 seconds (half-speed
mode) since the Belt Cleaner receives the Cleaner Cam
Solenoid OFF signal.

(b) Irregular cleaning
Table 2-14. Irregular Cleaning On/Off Timing
ON timing While the IBT is driven, the solenoid comes ON G3 seconds
before the top edge of the image (printed area) on the IBT
surface advances to the position where the Belt cleaner
assembly cleans the belt.
OFF timing Goes from ON to OFF G2 seconds before the top edge of
the next image (printed area) on the IBT surface advances
to the position where the Belt cleaner assembly cleans the
belt.
(c) Error cleaning
Table 2-15. Error Cleaning On/Off Timing
ON timing While the IBT is driven, the solenoid comes ON G1 second
before the top edge of the image (printed area) on the IBT
surface advances to the position where the Belt cleaner
assembly cleans the belt.
OFF timing Goes from ON to OFF G2 seconds before the top edge of
the next image (printed area) on the IBT surface advances
to the position where the Belt cleaner assembly cleans the
belt.
3. Belt Cleaner Assembly end of life detection
The life of the Belt Cleaner Assembly is the same as the printer life.
Note the number of printed sheets (=IBT cleaning times) is counted
but not to detect the end of life.
