Adjustment Item Purpose Method Outline Tool
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
USB ID input
This 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
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
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
First dot position
adjustment
This 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
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
Bi-D adjustment
This corrects print start timing in bi-directional printing to improve the print
quality.
A Bi-D adjustment pattern is printed. Black and color patterns are
printed for each of the five dot sizes (ECO, VSD1, VSD2, VSD3,
VSD4). So, there are 10 groups. Examine the patterns and enter the
value for the pattern with no gap and overlap for each mode.
• Adjustment Program
Initialize PF
deterioration offset
This 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 tis maximum value (10000).
• Adjustment Program
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.
