Operating Principles

2.2.2.1 Platen Gap Adjust Lever

The platen gap adjust lever, which is attached to the carriage unit, needs to be set to an appropriate
position for the paper thickness. To change the platen gap, put the printer in the PAUSE state; then
press the Font button, while holding down the Alt button. The carriage unit moves the platen gap
position automatically.

2.2.3 Paper Feed Mechanism

This printer's paper feed mechanism can feed paper only from 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 feed mechanism (paper advancing operation, paper pickup 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 sequence
(2 W1-2 phase).
