1.2 Power-On Sequence
This section describes the power-on sequences in two conditions. The preconditions are as follows.
Condition 1: Normal power-on sequence (See Table 1-1.)
Turning on the printer after turning it off without an error.
Initial ink charge has finished and every cartridge has sufficient ink.
No paper on the paper path.
The Printhead is capped with the Cap Assy.
The CR Unit is normally fixed by the Change Lever.
Maintenance error recovery has never been performed.

Note 1: The rotation directions of the PF Motor are as follows.
Clockwise: |
Paper is fed normally |
Counterclockwise: |
Paper is fed backward |
*2: The conditions of the CR lock are as follows.
Red |
CR lock is set |
White |
CR lock is released |
*3: The fatal error occurs if there is a problem such as the fuse blew. *4: The empty suction operation may occur depending on the situation.
*5: Executed when the detected temperature is under 5 oC (41oF) by the thermistor on the Printhead.

Condition 2: Power-on sequence after recovering from a paper jam error (See Table 1-2.)
Turning on the printer after turning it off with a paper jam fatal error.
There still remains paper on the paper path out of the detecting area of the PE Sensor.
Maintenance error recovery has never been performed.

4-3.The CR Unit quickly returns to its home position, and displays on the LCD or with flashing LEDs 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 1-1) is executed again.*2
Note *1: “Paper exists” is detected when the CR Unit touches the paper. When “paper does not exist” is detected, the power-on sequence of condition 1 (Table 1-1) is executed from No.4.
*2: If the paper jam error cannot be solved after repeating the power-on sequence on condition 2 (Table 1-2) twice, the printer turns into the paper jam fatal error for the third time.
To recover from the maintenance error, the dedicated software that can be downloaded from the web site which can be accessed from STM3 is required.
The printer operation related to the maintenance error recovery is as follows.
•When the waste ink counter reaches the threshold value (1) for the first time and the maintenance error occurs, the counter threshold of the maintenance error is changed to threshold value 2 after performing recovery from the maintenance error.
•After the threshold value (2) is enabled, the warning; to notify the possibility of ink leakage out of the printer, is displayed every time the waste ink counter increases by 1%.
•If the waste ink counter reaches the threshold value (2), the maintenance error occurs. Then, the waste ink counter is changed back to the threshold value (1) after recovering from the maintenance error, and the warning is displayed repeatedly according to the increment of the waste ink counter until the maintenance error occurs when the threshold value (2) is reached.
(Recovery from the maintenance error can be performed up to the specified number of times.)
