Adjustment Item | Purpose | Method Outline | Tool |
PG adjustment | Install the Head Nozzle surface parallel to the printing surface and set the gap between the paper and the HeadNozzle 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 1.15 mm, 1.3 mm |
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. Whenthis function is performed, the upper limit value of the ink tube ounter is automatically set. With this function, the serial number written on the main board can be checked, and also writing the serial number to the main board can be performed when replacing the board | Select the target market. The selected market settings are automatically written to the main board. When writing the serial number, enter and re-enter (for confirmation) the printer serial number, then press the input button. | Adjustment Program |
Head ID input | This must be carried out after replacing the print head in order to enter the new print head ID (Head ID) that reduces variation between print heads | Enter the ID printed on the Head QR code label attached on the print head. The correction values are automatically written to the main board. | Adjustment Program |
Initialize PF deterioration offse | 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 fromthe 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. | [1]Adjustment Program [2] Ruler |
Head angular adjustment | This must be carried out after replacing the print head in order to correct tilt of the print head 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 | 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 | [1]Adjustment Program [2] 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 | Adjustment Program Ruler. |
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. | 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 isapplied when printing in the corresponding mode. For some scanners, two PFP base scales are required | [1] Specified Scanner [2] 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. | Adjustment Program |
MAINTENANCE ITEMS
Maintenance Item | Purpose | Method Outline | 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 cleaning can be selected from the normal cleaning or the power cleaning. Whether to reflect the discharged ink amount to the waste ink pad counter or not can also be selected as an option. 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 |
Maintenance counter | The printer causes a maintenance error when the maintenance counter (for the Waste Ink Tray, Waste Ink Pad Lower) reaches its maximum. Use this to reset the counter after replacing the Waste Ink Pad and Waste Ink Pad Lower, and use this to reset the ink tube counter when replacing the Ink Supply Tube. 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 | Select the replaced parts, and reset the corresponding counters. | Adjustment Program |
Ink charge | This function is used to charge ink to the components composing the ink path such as Print head after replacing them | The ink charge can be selected from the charge to Print head only or the charge through Ink Tube, Adapter to Print head. Whether to reflect the discharged ink amount to the waste ink pad counter or not can also be selected as an option. Select the range to charge ink and options, and then press the execute button to execute the ink charge to the selected range automatically. After ink charge, print a nozzle check pattern to check if all nozzles are firing ink properly. | Adjustment Program |
Small ink counter reset | When an ink out error occurs even though some ink is still in the Ink Supply Tank Assy (in the case when the ink counter in the printer and the actual ink remaining amount do not match), this function can decrease the ink counter (resetting the counter partially) to adjust the counter with the actual ink remaining amount | If the execute button is pressed, the ink counter value is automatically set. But if no ink out error is occurring, the message which says the function cannot be executed appears and no reset will be made. | Adjustment Program |
Final check pattern print | A4 size US Letter size | Use this to check if the all adjustments have been properly made. | The all adjustment patterns are printed automatically. |
EEPROM dump | Use this to readout the EEPROM data for analysis | The all EEPROM data is automatically readout and stored as a file |
