Top of Form (TOF)
Important!
If you turn the platen knob when the printer is on, the Top of
Form misaligns. Always shut the printer off before turning
the platen knob!
Note: The factory default setting for the Top of Form (where
the printing should begin) is 1" down from the top of the
page.
Top of Form sets the print start position for the printer. It is
adjustable in increments of 1/144 of an inch. The amount of
adjustment is limited to avoid paper jams.
The first line prints at the red line of the plastic paper shield (1)
on the printhead.
Top of Form (TOF) and Forms Tear-Off
Note: Your software may print the first line of print above or
below where TOF is set. You may need to adjust the
TOF to meet your software’s requirements.
The Top of Form and Forms Tear-Off settings of your printer
interact. How you set the Top of Form depends on whether
Forms Tear-Off is On (set to 500 ms, 1 sec, or 2 sec) or OFF
(the factory default setting).
