Theory of Operation
Tray 1 (MPT) & Registration
■ Tray 1 (MPT) Turn Clutch
The Turn Clutch transmits drive energy from the Drive Assembly to the
Turn Roller.
■ Tray 1 (MPT) Turn Roller
The Turn Roller is rotated by the drive from the Drive Assembly through
the Turn Clutch to feed paper from the Tray 1 (MPT) or duplex paper path
to the Registration Chute.
■ Tray 1 (MPT) Registration Sensor
The Registration Sensor detects paper when the paper leading edge
reaches the Registration Chute. When paper is fed from Tray 1 (MPT), the
Registration Sensor measures the paper length. The On time of the
Registration Sensor is converted into the paper length.
Note
On : The paper activates the Actuator.
■
Tray 1 (MPT) Registration Clutch
The Registration Clutch transmits drive energy from the Main Drive to the
Registration Rubber Roller, and transports paper from Tray 1 (MPT) and
the duplex path to the Print Cartridge direction. The timing of sheets
feeding from the Registration is adjusted by the duration of the
Registration Clutch operation so that the toner image on the drum can be
transferred to the appropriate position on the sheet.
