6-2.The PF Motor rotates clockwise while monitoring
the PG sensor.
Any
position
6-3.After the PG sensor switched from Off to On, the
PF Motor rotates clockwise by the specified step
until it detects the PG-- (APG home position).
↓
6-4. After detecting the APG home position, the carriage
slightly moves to the 80-digit side.
↓
6-5. After the PF Motor rotates counterclockwise by the
specified step, it rotates clockwise to confirm the PG
sensor is set to On-state.
PG--
6-6.The carriage slowly returns to its home position.

7. Setting the APG to PG++
7-1.The carriage slowly moves to the Right Frame and
stops there.
↓
7-2.The PF Motor rotates clockwise and sets to PG++.
PG++
7-3.The carriage slowly returns to its home position.

8. PF initialization
8-1.Checks if paper exists by the PE sensor

and the
PF Motor rotates clockwise for one second.

9. PF Motor measurement
9-1.The PF motor rotates clockwise for four seconds,
and performs a load measurement.

10-1.The PF Motor rotates clockwise, and releases the
CR lock.
↓
10-2.The carriage moves back and forth between CR
lock and the 80-digit side for two times.

12.CR measurement and PW sensor initialization
12-1.The PF Motor rotates clockwise, and releases the
CR lock.
↓
12-2.The carriage slowly moves to the 80-digit side.
↓
12-3.The carriage performs a load measurement while
moving to the VHCheck position, and records the
detected voltage of the PW sensor at the specified
three positions, then stops.
↓
12-4.The carriage detects the voltage of the PW sensor
at the carriage stop position (the black area at the
Paper Guide Front).
↓
12-5.The carriage performs a load measurement while
moving to the 0-digit side, and stops.
↓
12-6.The carriage performs a load measurement while
moving to the VHCheck position, and records the
detected voltage of the PW sensor at the specified
three positions, then stops.
↓
12-7.The carriage detects the voltage of the PW sensor
at the carriage stop position (the black area at the
Paper Guide Front).
↓
12-8.The carriage performs a load measurement while
moving to the 0-digit side, and stops.
