ITB/ Paper Transfer
SM 7-63 D0CA/D0C9/D0C8/D0CB
7.9.4 ITB CONTACT
ITB has a contact mechanism to prevent the CMY drums from early deterioration. The color
drums are not needed for B/W printing, so this mechanism releases the ITB from the CMY
drums.
The ITB lift motor (M14) [B] rotates the ITB contact cam [A] through a gear. The contact slider
then moves and raises the image transfer roller [E] into contact with the CMY drums.
If the mechanism is defective (e.g. Paper jams), and is stuck with the CMY rollers up against the
ITB, the cam can be turned manually to lower the rollers. In order to remove the ITB unit without
damaging, turn the ITB contact cam's screw to the left until the flat part of the half moon on the
screw points to the right.
