6.2.2 MASTER CLAMPER OPENING MECHANISM

Clamper Mechanism

Clamper motor [A] - opens the clamper at the master eject position

↓

Gears [B]

↓

Link [C]

↓

Drum guide [D] - moves and engages the pin on the rear flange of the drum

↓

Lifts the clamper lever [E], and engages the drum pin [F]

↓

The lever [E] lifts the master eject arm [G] to release the master's leading edge [H]

from the clamper.

NOTE:

1) After the master making key is pressed and before the clamper motor

starts, the master eject position sensor [I] is checked (the drum must be

at the master eject position).

2) The sensor actuators on the link [C], the clamper open sensor [J], and

the clamper close sensor [K] determine the clamper open and close

positions.

3) The master clamper uses a magnetic plate to clamp the master's

leading edge.

4) The drum guide catches the drum at the master eject position while the

master clamper is being opened. When the clamper motor turns on in

reverse direction to close the clamper, the drum guide also disengages

the pin and the drum can turn.
