When the Power Supply Board, the CR Motor or the Carriage Shaft has been replaced individually or when the correction value of the EEPROM cannot be read out with the main board replacement, the correction value cannot be recalculated since the condition is the different from when it’s new, therefore, enter the worst value (on which heat generation limit is easily imposed).1. Select this function in the Adjustment Program. 2. Select the replacement parts and execute this function to measure automatically the variations and write the measurement values to the EEPROM on the Main Board. PF motor heat protection control When replacing the Printer Mechanism, this adjustment is made to measure manufacturing variations of the PF Motor and the Power Supply Board to make the most of the motor capabilities in motor heat generation control.

Maintenance Functions Function ItemPurposeMethod Outline Ink charge This function is used for Print Head replacement to drain Shipping Liquid of the after-sales service part in the head flow path and simultaneously fill ink in the head flow path to make all nozzles printable and stabilize the ink in the Print Head.1. Select this function in the Adjustment Program. 2. Transfer the factory-set command (CL execution command (Initial Ink Charge) is used as the command) to the printer to make the printer perform Initial Ink Charge operation. Head cleaning This function is used to execute cleaning 3 (CL3) when ink is not delivered from the Print Head properly, e.g. dot missing or skewed injection.1. Select this function in the Adjustment Program. 2. Execute CL3. Consumables maintenance counterThis function is used to read and reset the Protection Counters. 1. In the Adjustment Program, select value read or reset from this function. Make sure to replace the Waste Ink Pads managed by the protection counters before resetting the counter. Table 5-1.

If you have removed or replaced multiple parts, make sure to check the required adjustments for the all parts. And when multiple adjustments must be carried out, be sure to carry out them in the order given in the “Priority” row. Note *1 :When only removing the ASF Assy, you do not need to perform the adjustment. In that case, mark the installing positions before removing them, and make sure to align the markings when installing. See ?4.4.6 ASF Assy? (p96). *2 :Replacing the Waste Ink Tray Assy is necessary when resetting waste ink pad counter. *3 :When only removing the Carriage Shaft, you do not need to perform the adjustment. In that case, mark on the Parallelism Adjust Bushing (Left/Right) before removing them, and make sure to align the markings when installing. See ?4.4.5 Carriage Shaft / Carriage Unit? (p88).

Check the correction value by energizing it in the same way as for Stylus Photo R1800. 6PF Tension Measuring Tool1294120Measuring toolUsed to check whether or not the tension of the PF Drive Belt is within the specified value. If load is greater than the specified value, the PF Motor may generate heat, burning off the coil. Reversely, if load is less than the specified value, the paper feed position may shift. 7PF Roller Shaft Position Adjustment Jig1304993Adjusting jigUsed to check whether or not the deflection amount of the PF Roller Shaft is within the specified value. Adjustment values are confirmed in a pair with the level block. 8Level Block1304994Adjusting jigUsed to check whether or not deflection amount of the PF Roller Shaft is within the specified value. Adjustment values are confirmed in a pair with the PF Roller Shaft Position Adjustment Jig. 9Spanner (M3)Commercially availableToolUsed to loosen the screw that secures the Center Support Bushing when performing PF Roller Shaft Center Support Position Adjustment.

The lines on the top are printed while the carriage moves from the home to the other side (from 1 to 80 digit), and the lines at the bottom are printed while the carriage returns to the home (80 to 1 digit). Figure 5-1. Head Angular Adjustment Printout Pattern How to Judge Examine the printout patterns and enter the value (-10 to 10) for the most straight lines.Additional information In the following cases, reassemble or replace the Printhead and carry out the adjustment again. The difference between the adjusted values of 1 -> 80 and 80 -> 1 exceeds 8. The larger the difference is, the more the Printhead is tilted in the front-to- back direction. (Not parallel to the paper surface.) The average of the values of 1 -> 80 and 80 -> 1 falls outside the range from - 4 to +4. The further the value is beyond the range, the more the Printhead is tilted in the left-to-right direction.
