[Head Voltage Adjustment] Before performing this adjustment, print the stair-step pattern (Note 2) two times continuously with the old head (Note 1) or normal unit. The second print will be used as a sample of the print density.
Note 1: Only when the old head (faulty head) is not entirely damaged with black or white lines. Note 2: To print the stair-step test pattern, turn on the power switch while pressing the S1707 (CAPTURE) and S1717 (ENTER) on the SW39 board. (Press the S1707 (CAPTURE) and S1717 (ENTER) until a peep is heard.) Set the S1701 (Rotaly switch) to the position, and press the S1706 (print), then the print will start.

* VR201 is in the power block (1-468-364-11). Adjustment Location:
Adjustment Procedure: (1) To print the stair-step test pattern, turn on the power switch while pressing the S1707 (CAPTURE) and S1717 (ENTER) on the SW-39 board. (Press the S1707 (CAPTURE) and S1717 (ENTER) until a peep is heard.) Set the S1701 (Rotaly switch) to the position, and press the S1706 (print), then the print will start. (2) After printing, repeat (1) immediately. (3) Compare the second printed pattern density with that of the sample, and if the density differs, perform the following adjustment. (4) Adjust VR201 according to the print density. If darker than the sample: Decrease the head voltage. If lighter than the sample: Increase the head voltage. (5) Print the stair-step pattern two times continuously. (6) Compare the second printed pattern density with that of the simple, and if the density differs, repeat steps (3) to (6).
Note: Only one print is required after the second time.
