2.6 Power-On Sequence

This section describes the power-on sequences.
 Condition
 Completing ink charge.
 No paper on the paper path.

The Printhead is capped with the Cap of the Ink System.
 PG position is set to PG Typ.
 The Carriage is locked by the CR lock.
The following explains how to use the simplified diagrams in
C H E C K
P O I N T 2-6. The diagrams show the movement of each component as seen
from the front of the printer.
The rotation direction of the ASF
Motor
Clockwise:
LD Roller rotates backward
Counterclockwise:
LD Roller rotates normally (Paper is fed)
The following shows clockwise rotation.
Digit number of CR
130
The rotation direction of the PF Motor
Clockwise:
Paper is fed normally
Counterclockwise:
Paper is fed backward
The above shows clockwise rotation.
Figure 2-4. Carriage Movement
Operating Principles
PG variation by APG Motor drive
PG becomes narrower (down-arrow):
Clockwise rotation
PG becomes wider (up-arrow):
Counterclockwise rotation
The following shows when PG is narrow.

The condition of the CR lock
Red: CR lock is set
White:CR lock is released
The above shows the CR lock is set.
Table 2-6. Operation of the power-on sequence
Operation
1. Checking waste ink overflow
1-1. Reads out the protection counter value to check
waste ink overflow.
2. APG initialization
2-1. The APG Motor rotates counterclockwise until
the PG position is set to PG++ to initialize the
APG mechanism.
Table
3. Seeking the home position
3-1. The carriage moves to the 0-digit side slowly and
confirms it touches the Right Frame.
3-2. The carriage moves to the 130-digit side slowly
and confirms it touches the CR lock.
3-3. The carriage moves to the 0-digit side slowly and
confirms it touches the Right Frame, and the
home position is fixed.
Afterward, the carriage position is monitored
according to the signals from the CR Encoder.
4. Releasing the CR lock
4-1. The Pump motor rotates counterclockwise and
releases the CR lock.
4-2. The carriage slowly moves to the 130-digit side to
the CR lock check position.
4-3. The carriage slightly moves to the 130-digit side.
