3. OPERATION AND TIMING
3. Putting the Transfer Blade In/Out of Position
As shown in Figure 3-632, four transfer blades are mounted, one each for Y, M, C, and Bk. With the
exception of transfer charging operation, the blade is moved away from the transfer belt to limit its load on the
belt — as when the last paper has moved past the transfer belt.
When the registration roller clutch (CL8) turns on, the transfer blade is put in transfer position for
retention of paper and transfer.
The transfer blade is put in and out of position by the drive of the transfer blade solenoid (SL7Y, SL7M,
SL7C, SL7Bk).
The transfer blade solenoid is a latching type, which can hold its steel core out or in by switching the
drive signal without the need for retention current.
