Contact-Release Mechanism

[A]
The transfer-belt cleaning unit [A] is kept away from the transfer belt when not
performing transfer belt cleaning. The transfer-belt cleaning unit remains in contact
with the transfer belt while cleaning takes place. The following steps illustrate this
process and the components involved.
• The cleaning unit solenoid [B] moves the front lever [E].
• The front lever engages the front latch of the camshaft [J].
• The rear lever engages the rear latch of the camshaft [F].
• The cam then lifts the cleaning unit interface [D].
When the cleaning unit solenoid is de-activated (off) [H], the front lever [I] releases
the front latch [J] on the camshaft. At this time, the rear lever [G] engages the rear
latch [F] on the camshaft. 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 is
moved away from the transfer belt.
When the cleaning unit solenoid is activated (on) [h], the front lever [i] engages the
front latch [j] on the camshaft. At this moment, the rear lever [g] releases the rear
latch [f] on the camshaft. 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.
