DETAILED SECTION DESCRIPTIONS

PAPER FEED

2.5. PAPER FEED

The paper feed motor [A] drives the feed roller [B] and the relay roller [C].

The paper feed clutch [D] turns on when the unit feeds a sheet of paper from

the cassette. It transfers the motor drive to the feed roller until the paper

reaches the relay sensor [E].

If only one paper feed unit is installed:

The host machine's paper feed motor feeds the paper into the printer

mechanism after the leading edge of the paper passes the host machine's

registration sensor.

If two paper feed units are installed:

The feed motor in the upper paper feed unit feeds the paper to the fax

machine's registration area after the leading edge of the paper passes the

feed unit's relay sensor. The fax machine's paper feed motor then feeds the

paper into the printer mechanism.

Jam Conditions

A jam condition is detected when one of the following conditions occurs:

1. The relay sensor does not activate 2 s after the paper feed clutch was

turned on [error code 9-50 or 9-52].

2. The registration sensor in the fax machine does not activate 2 s after the

relay sensor in the paper feed unit was activated [error code 9-51].

3. The relay sensor in the upper paper feed unit does not activate 2 s after

the relay sensor in the lower paper feed unit was activated (when two pa-

per feed units are installed) [error code 9-53].
