Objective: Left margin of 116.8 mm ± 0.5 mm (4.6 ± 0.2 inch)
measured from inside Side Frame, Left.
Adjustment Procedure
1. Set the 1, 5 or 10 sheets of paper in the tractor, and load the paper by
pressing the [Load] button.
2. From the Adjustment Program, select the Left Margin Adjustment.
3. Click Print in Mode A to print the left margin check pattern with the
adjustment value currently saved in EEPROM.
4. Refer to Figure 5-30, and measure the distance between the printed
left line and the left frame. Check whether the distance matches the
specification: 116.8 mm ± 0.5 mm.
5. If the line needs adjustment, type an adjustment value for each mode
into each of the input boxes, where 1 step = 1/480 inch.
A negative (e.g., “-12”) value moves the print position to the right,
and a positive value moves it to the left.
6. Click Write to save the new parameter for next print test.
7. Click Print again to print the left margin check pattern with the new
parameters.
8. Repeat Step 4 to Step 7 until the margin is within specifications.
9. Make the same adjustment for each print mode, and each paper
thickness.
