PG adjustment

Install the Head Nozzle surface parallel to the printing surface and set the gap between the paper and the Head Nozzle surface to the specified value.

Mechanical adjustment using the thickness gauges. Make a proper adjustment according to the result whether the manually-moved carriage (printhead) runs over or hits against the gauges placed on the platen.

• Thickness Gauge 1.15mm, 1.3mm

EEPROM data copy

When the main board needs to be replaced, use this to copy adjustment values stored on the old main board to the new board. If this copy is completed successfully, all the other adjustments required after replacing the main board are no longer be necessary.

Readout the EEPROM data from the main board before removing it. Then replace the board with a new one, and load the EEPROM data to the new board.

• Adjustment Program

Initial setting

This must be carried out after replacing the main board to apply settings for the target market.

Select the target market. The selected market settings are automatically written to the main board.

• Adjustment Program

Head ID input

This must be carried out after replacing the printhead in order to enter the new printhead ID (Head ID) that reduces variation between printheads.

Enter the ID printed on the Head QR code label attached on the printhead. The correction values are automatically written to the main board.

• Adjustment Program

USB ID input

Sets a USB ID of the printer. A computer identifies the printer by the ID when multiple same models are connected via a USB hub.

Enter the product serial number of the printer. The ID is automatically generated and written to the main board.

• Adjustment Program

Initialize PF deterioration offset

Resets the counter to maintain paper feed accuracy which decreases due to paper dust.

Reset the counter to its default.

• Adjustment Program

Disenable PF deterioration offset

When reading the counter value from the old main board is impossible in the case of replacing the board, use this to set the counter to its maximum value.

Set the counter to its maximum value (3000).

• Adjustment Program

TOP margin adjustment

This corrects top margin of printout.

A top margin adjustment pattern is printed. Examine the lines printed near the top edge of the printout, and enter the value for the line that is exactly 3 mm away from the top edge.

• Adjustment Program

• Ruler

Head angular adjustment

This must be carried out after replacing the printhead in order to correct tilt of the printhead by software.

A head angular adjustment pattern is printed. Examine the printed lines and enter the value for the most straight lines.

• Adjustment Program

For information on how to carry out the adjustments and media required for the adjustments, see the instructions displayed by the Adjustment Program.

Bi-D adjustment

Corrects print start timing in bi-directional printing to improve the print quality.

A Bi-D adjustment pattern is printed. Examine the patterns and enter the value for the pattern with no gap and overlap for each mode.

• Adjustment Program

First dot position adjustment

Corrects left margin of printout. The print start position in the carriage moving direction is corrected by software.

A first dot adjustment pattern is printed. Examine the lines printed near the left edge of the printout and enter the value for the line that is exactly 5 mm away from the left edge.

• Adjustment Program

• Ruler

PW adjustment

This adjustment is made to correct the mounting position of the PW Sensor on a software basis to adjust the detection position and Nozzle position dispersion.

A PW adjustment pattern is printed. Examine the printout patterns and enter the value for the line that is exactly 5mm away from the paper edge for each of the left, right, top and bottom.

PF adjustment

Corrects variations in paper feed accuracy when using the Microweave to achieve higher print quality.

A PF adjustment pattern is printed. Examine the printout patterns and select the value for the best pattern. The correction value is registered.

• Adjustment Program

BRS/PFP adjustment

This adjustment is made to ensure high print quality at high print speed. For more details, see "2.3 Banding Reduction System (BRS) / Paper Feed Amount Profile Correction (PFP) (p. 26)

Print the adjustment pattern to be scanned by a specified scanner. According to the scanned result, a correction value is automatically calculated and stored into the serial flash ROM on the main board. The correction value is applied when printing in the corresponding mode.

• Specified Scanner

• PFP base scale

CR motor heat protection control

This must be carried out for efficient heat control of the CR motor. Electrical variation of the motor and the power supply board are measured to acquire correction values for them.

Select the parts that you replaced. The correction values are automatically written to the main board.

Tool

Head cleaning

This function is used to execute Cleaning efficiently when ink is not delivered from the Head properly, e.g. dot missing.

The head cleaning is performed automatically. After the cleaning, print a nozzle check pattern to check if all nozzles are firing ink properly.

• Adjustment Program

Waste ink pad counter

The printer causes a maintenance error when the waste ink pad counter reaches its maximum. Use this to reset the counter after replacing the Waste Ink Pad. If you find the counter is close to the maximum during servicing, carry out the pad replacement and the counter reset to avoid the printer returned from the user due to the maintenance error.

After replacing the Waste Ink Pad, reset the counter to its default.

• Adjustment Program

Ink charge

This must be carried out after replacing the printhead in order to fill ink inside the new printhead. The printhead becomes ready for print.

Filling ink inside the printhead is automatically performed. Print a nozzle check pattern to check if all nozzles are firing ink properly.
