An apparatus and method for taking up the slack in the web material between
the supply roller and the take-up roller in the web cleaning assembly of
an electrophotographic apparatus. A clutch mechanism is positioned between
the drive gear on the take-up roller and the hub of the motor that drives
the drive gear. A spring-biased pawl on the hub engages a tooth of an
inner gear on the drive gear to provide a driving connection between the
hub and the take-up gear when the motor drives the hub in a first
direction but effectively releases the driving connection when the take-up
gear is manually rotated while the motor is idle. This allows the take-up
roller to be rotated to take up the slack in the web without having to
rotate the motor.
