Power-On Sequence - Epson Stylus NX510 Service Manual

Epson Stylus NX510/515/SX510W/515W/TX550W/NX415/SX410/415/TX410/419/NX215/SX210/215/TX210/213/219/ME OFFICE 510

2.2 Power-On Sequence

This section describes the power-on sequences in two conditions. The sequences for
these three series are basically similar with the exception of the CR lock setting
sequence (operation 8); therefore, they are described based on NX510 series in the
following conditions.
Condition 1: Normal power-on sequence
Turning on the printer after turning it off without an error.
Completing ink charge.
No paper on the paper path.
The Printhead is capped with the Cap of the Ink System.
The Carriage is fixed by the CR Lock.
NOTE: For SX410/SX210 series, the CR lock setting sequence (operation 8)
differs from the sequence for NX510 series.
Condition 2: Power-on sequence after recovering from a paper jam error
(refer to Table 2-5)
Turning on the printer after turning it off with a paper jam error.
There still remains paper on the paper path out of the detecting area of the PE
sensor.
NOTE: For SX410 series, the detecting remaining paper sequence (operation 6)
is not implemented.
Table 2-4. Condition 1: Normal power-on sequence
*1
Operation
1. Checking waste ink overflow
*3
2. Avoiding deadlock sequence
2-1.The carriage moves to the 0-digit side slowly and confirms it
touches the CR lock.
2-2.The carriage slightly moves to the 80-digit side slowly.
2-3.The PF Motor rotates clockwise, and releases the CR lock.

Power-On Sequence
Table 2-4. Condition 1: Normal power-on sequence
Operation
2-4.The carriage moves to the 0-digit side slowly and confirms it
touches the Right Frame.
2-5.The carriage returns to its home position.
3. Releasing the CR lock
3-1.The PF motor rotates clockwise, and releases the CR lock.
4. Seeking the home position
4-1.The carriage moves to the 0-digit side slowly and confirms it
touches the Right Frame.
4-2.The carriage slowly moves to the CR lock set position.
4-3.The PF motor rotates clockwise, and releases the CR lock.
4-4.The PF motor rotates counterclockwise, and sets the CR lock.
4-5.The carriage moves to the 80-digit side slowly and confirms it
touches the CR lock.

4-6.The carriage slowly moves to the 0-digit side to the CR lock set
position.
4-7.The PF motor rotates clockwise, and releases the CR lock.
4-8.The carriage moves to the 80-digit side slowly and confirms it does
not touch the CR lock.
4-9.The carriage slowly moves to its original position, and the home
position is fixed.
Afterward, the carriage position is monitored according to the
signals from the CR Encoder.
