Epson Stylus SX415 - 2.3 Printer Initialization

Epson Stylus NX510/515/SX510W/515W/TX550W/NX415/SX410/415/TX410/419/NX215/SX210/215/TX210/213/219/ME OFFICE 510 Revision A
OPERATING PRINCIPLES Printer Initialization 55
Confidential
Note : The power-on operations of SX410 series in condition 2 differs from the above
sequence since the detecting remaining paper sequence (operation 6) is not
implemented for SX410 series.
Note *1 : “Paper exists” is detected when the carriage touches the paper. When “paper does
not exist” is detected, the power-on sequence of condition 1(Table 2-4) is executed
from No.6.
*2 : If the paper jam error cannot be solved after repeating the power-on sequence on
condition 2 (Table 2-5) twice, the printer turns into the paper jam fatal error for the
third time.
2.3 Printer Initialization
There are four kinds of initialization method, and the following explains each
initialization
1. Hardware initialization
This printer is initialized when turning the printer power on, or printer recognized
the cold-reset command (remote RS command).
When printer is initialized, the following actions are performed.
(a) Initializes printer mechanism
(b) Clears input data buffer
(c) Clears print buffer
(d) Sets default values
2. Operator initialization
Initialization when resetting the USB software, and the following are performed.
(a) Clears input data buffer
(b) Clears print buffer
(c) Sets default values
3. Software initialization
The ESC@ command also initialize the printer.
When printer is initialized, the following actions are performed.
(a) Clears print buffer
(b) Sets default values
4. IEEE 1284.4 “rs” command initialization
The printer recognized the IEEE 1284.4 “rs” command.
When printer is initialized, the following action is performed.
 Initialization when an error occurs.
(a) Initializes printer mechanism
(b) Clears input data buffer
(c) Clears print buffer
(d) Sets default values
 Initialization in normal operation
(a) Clears input data buffer
(b) Clears print buffer
(c) Sets default values
Table 2-5. Condition 2: Power-on sequence after recovering from a paper jam error
Operation
Carriage/PF Roller
movement and position
Executes No.1 to No.5 on the normal power-on sequence (Table 2-4).
6. Detecting remaining paper
6-1.The carriage moves to the 80-digit side and confirms there is no
paper.
*1
6-2.The carriage quickly returns to its home position, and displays on
the LCD that the paper jam error occurs.
When the user removes the paper and releases the paper jam error by panel operation, the normal power-
on sequence from No.1
(Table 2-4) is executed again.*
