Principles of Operation

Cleaning Unit Operation
For every print cycle, the home, engage, and disengage moves are required. During the nor-
mal run mode, the drive motor will first position the cam so that the sensor signal will transition
from high to low, refer to
Table 2
:
Once the cam has been homed,
Figure 31
, the cleaning unit drives to an engaged position.
There are two variables to the motor profile that will be changed as a function of the cleaning
unit supply roll age. These two variables are the penetration of the supply roll into the drum
surface and the time between blade landing and supply roll landing. The engage motion profile
is initiated by the drum position. When the drum (and the expected location of the lead edge of
the image) rotates to the required position, the engage profile described below is commanded.
The variable time and penetration will be adjusted based on the age of the supply roll in the
machine. As the roll ages, the roll penetration will have to be increased and the time from blade
engage and roll touch will be shortened.
Figure 31 Cleaning unit camshaft
The motor motion profile to disengage the cleaning unit is again initiated by the drum position.
The motion profile is the inverse of the engage and must accommodate the total engage
motion, which is a function of the cleaning unit roll age.
At ready state the cleaning unit performs an auto cleaning cycle after every IOD cycle to cap-
ture dust particles which may collect on the drum. At the end of every cleaning cycle, the CU
cam will be returned all the way to the home position. When a print cycle is started, the clean-
ing unit cam is engaged against the cam followers to minimize noise and wear on the cam and
cam followers. During print state, a cleaning cycle is performed after every image transfer
cycle. There may be special multi pass prints which do not require a transfix cycle until the vary
last pass is completed.
Fault state drives the cleaning unit cam to the cleaning unit removal position so that the cam
can be removed by the customer. The cleaning unit is locked if any of the machine doors are
open. The cleaning unit cam motor is locked away from the home position if the cleaning unit
cartridge is not detected.
