Motors

The DC Controller controls the Exhaust Fan, the Main Motor, and the Laser/Scanner Motor. The remaining motors and solenoids are controlled by State Machines on the motor’s assembly. The condition of these motors and solenoids is monitored by the DC Controller through serial data lines.

The Main Motor (M1) rotates after any printer door is opened and closed, during the Warm-up period, the Initial Rotation period, the Print period, or the Last Rotation Period. The Scanner Motor (M5) is controlled and monitored by the DC Controller PCA. M5 operates during the Initial Rotation period, the Print period, and the Last Rotation period.

The Paper Feed Assembly Drive Motor (M2) runs during the Print Period. This motor provides the drive to pick paper from the PC tray, and deliver it to the Input/Registration Sensor (PS1). The LC Assembly Motor (M3) provides the drive to pick paper from the optional 500-sheet Lower Cassette, and deliver it to the Input/Registration Sensor (PS1). M3 is mounted on the 500-sheet Lower Cassette. The Envelope Feeder Drive Motor (M4) provides the drive to pick envelopes from the envelope feeder and deliver them to the Input/Registration Sensor (PS1). M4 is mounted on the optional Envelope Feeder.

The Exhaust Fan Motor (FM1) is controlled and monitored by the DC Controller PCA. The Exhaust Fan Motor operates at low-speed during the Warm-up period, Standby period, and during PowerSave. It operates at high-speed during the Initial Rotation period, the Print period, and the Last Rotation period.

The Paper Feed Assembly Motor (M2) is controlled by the Paper Control PCA. The Paper Feed Assembly Motor drives the pickup rollers through SL1 and SL2. These rollers pick media from either the PC tray (Tray 2) or the MP tray (Tray 1), and deliver the media to the Paper Registration Sensor (PS1).
