2.2.3 Paper Feed Mechanism
(B)
printer’s paper feed mechanism can paper only the built-in ASF (auto sheet feeder).
The paper feed drive motor is a 4-phase, 96-pole, hybrid-type stepping motor that directly drives
the paper (paper advancing operation, paper pick-up operation). This motor also
drives the pump mechanism, but only when the printer is in the cleaning state. The paper feed
drive method is driven by the 2-2 phase drive method, except the paper feed drive
phase).
