    Chapter 2 c. Reversing/Moving the Original 2 The machine rotates the feed motor in normal direction and the delivery reversal motor in reverse to move sheets at the same time. The machine stops the delivery reversal motor when the originals have moved a specific distance. The machine then drives the lock motor for a specific number of pulses to lock the platen upstream roller in place.

  • Page 52: Detecting Jams

    Chapter 2 +24V MODE RESET Motor Driver REF1 REF2 ADF driver PCB F-2-39 The CPU (IC9) on the ADF driver PCB receives data (command) from the host machine on printing mode (magnification, operation mode, timing); in response, it generates drive pulses to drive the feed motor (M2). The feed motor (M2) is a stepping motor, and its direction and speed of rotation are changed by changing the order of drive pulses (A, A*, B, B*).

  • Page 53: Stamp Operation

    Chapter 2 The machine is supplied with 2 types of power by the host machine 24 V and 13 V. The 24-V power is mainly used to drive loads (motor, clutch, solenoid), while the 13-V power is converted into 5 V by IC10 (DC-DC converter) for use by sensors and the ADF controller PCB. Unlike other models, the machine will remain supplied with power even when its feeder cover is opened.
