Developing roller pressure mechanism

• Generally, the Ds rollers are pressed up against the PC drum flanges, so that an opti-
mum distance is maintained between the PC drum and the developing roller. (The Ds
rollers are mounted coaxially with the developing roller and designed to be larger in
diameter than the developing roller. The developing roller therefore does not contact the
PC drum.)
• A mechanism is provided that releases the Ds rollers (developing roller) from the PC
drum to prevent the photo conductor from being damaged when the drum unit is to be
removed.
• Rotating the release lever clockwise will rotate the drum unit about the pivot, so that the
Ds rollers are pressed against the drum unit.
• Rotating the release lever counterclockwise will rotate the drum unit about the pivot, so
that the Ds rollers are released from the drum unit.
NOTE
• Whenever operating the release lever, be sure to place the PH window cleaning
tool in its home position (pushed in position). A PH window cleaning tool, with-
drawn from its home position, interferes with the release lever and can therefore
be damaged.
