Contact-Release Mechanism

[A]
The transfer-belt cleaning unit [A] stays away from the transfer belt when not
cleaning the transfer belt. The transfer-belt cleaning unit stays in contact with the
transfer belt when it cleans it. These components do this procedure:
• The cleaning unit solenoid [B] moves the front lever [E].
• The front lever engages the front latch of the cam shaft [J].
• The rear lever engages the rear latch of the cam shaft [F].
• The cam lifts the cleaning unit release pin [D].
When the cleaning unit solenoid is off [H], the front lever [I] releases the front latch
[J] on the cam shaft. At the same time, the rear lever [G] engages the rear latch [F]
on the cam shaft. In this position, the cam stays in its upper position [E] and
pushes up the cleaning unit release pin [D]. As a result, the cleaning unit stays
away from the transfer belt.
When the cleaning unit solenoid is on [h], the front lever [i] engages the front latch
[j] on the cam shaft. At the same time, the rear lever [g] releases the rear latch [f]
on the cam shaft. In this position, the cam stays in its lower position [e] and does
not push up the cleaning unit release pin [d]. As a result, the cleaning unit stays in
contact with the transfer belt.
