Adjusting TOF (Top of Form) position

Use the following procedure to set TOF to accord with the
reference position (6.35 mm (0.25 in)). The reference position
refers to the first line of the paper i.e. the position to which the
printer feeds the paper when automatically loading the paper.

Note

Adjusting the TOF can be done in cut sheet mode or
continuous forms mode.

1.

Print out the menu settings of the printer as in
“Confirming current settings” on page 32 and confirm that
the TOF (in cut sheet mode or continuous forms mode) is

6.35 mm (0.25 in).

2.

Set the Paper Type lever to the required paper type.

3.

When continuous forms are used, place the paper on the
Pin Tractor.

For cut sheet mode, do not insert the paper at this stage.

4.

In continuous forms mode, press the FF/LOAD button.

In cut sheet manual feeding mode, press the FF/LOAD
button and place the paper on the Paper Tray.

After the paper has started to be taken into the printer,
continue to press the FF/LOAD button and the paper is
taken into the 6.35 mm (0.25 in) position.

5.

Align the paper with the first print line position as follows:

In off-line mode, press the following buttons to adjust the
first printing line:

• To feed the paper forward by a small amount, hold
down the SHIFT button and press the FF/LOAD
button.

• To feed the paper backward by a small amount, hold
down the SHIFT button and press the LF button.
