3. OPERATION AND TIMING
b. Transfer Cleaning Blade
The transfer cleaning blade is used to remove toner from the transfer during image position correction.
(See Chapter 3. IV. G. Image Position Correction.)
The cleaning blade is set to its cleaning position by the drive of the transfer cleaning blade solenoid
(SL6) only at the time of image position correction.
Once set to position, the cleaning blade remains as is but moves away from the transfer belt (released)
over the seam.
The transfer cleaning blade solenoid is a latching type, which can keep its steel core out or in to suit
either of two drive signals without the need for retention current.
