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 1/180 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).
