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.

Table 1-1. Condition 1: Normal Power-on Sequence

Operation*1

CR Unit/PF Roller

movement and

position*2

1.

Printhead initialization and fuse inspection

1-1.Initializes the Printhead, and checks for the fuse on the circuit boards in the printer.*3

2.

Checking for waste ink overflow

2-1.Checks the waste ink counter if the waste ink overflow is occurring.

3.

Seeking the home position

3-1.The CR Unit moves to the 80-digit side slowly and confirms it touches the Change Lever (CR lock).

3-2.The CR Unit moves to the 0-digit side slowly.

3-3.After the PE Sensor checks if paper exists, the PF Motor rotates clockwise for one second and releases the CR lock.

3-4.While checking if the CR Unit does not touch the Change Lever (CR lock) or the foreign material, the CR Unit

moves to the 80-digit side slowly until it touches the Left Frame.

3-5.The distance from the position where the CR Unit touched to the Left Frame is regarded as the standard distance

from the origin position, and the home position is fixed.

From then on, the CR Unit position is monitored according to the signals from the CR Encoder.

3-6.The CR Unit moves to near its home position quickly.

4.

PF Motor Measurement

4-1.The PF Motor rotates clockwise until the PF Roller turns five times to perform a load measurement.

5.

Detecting ink cartridge and initializing ink system*4

5-1.The CR Unit returns to its home position.

6.

Low temperature operation sequence*5

6-1.The CR Unit quickly moves back and forth between near the Change Lever and near the Left Frame for two times.

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.

Table 1-2. Condition 2: Power-on Sequence after Recovering from a Paper Jam Error

CR Unit/PF Roller

Operation

movement and

position

Executes No.1 to No.3 on the normal power-on sequence (Table 1-1).

4. Detecting remaining paper

4-1.5.The CR Unit returns to its home position.

4-2.The CR Unit moves to the 80-digit side and confirms there is no paper.*1

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.)
