Setting the Top of Form (TOF) Position

The factory default setting for the Top of the Form (TOF) (where the printing should begin) is one inch down from the top of the page. The first line prints at the red line on the plastic paper shield (1). 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 needs.

Determine the Forms Tear-Off Setting
How you set TOF is determined by the Forms Tear-Off setting. Forms Tear-Off automatically moves the paper from the initial printing position to the tear- off position, allowing a printed page to be torn off without wasting paper or adjusting the printer. Forms Tear-Off is factory set to OFF.

Setting Top of Form with Forms Tear-Off set OFF

1. Press SEL/MENU to take the printer offline. The SEL light goes out.
2. Press and hold SHIFT, then press LF/MICRO Feed Down or FF/LOAD/Micro Feed Up.

! For steps to set Forms Tear Off ON and adjust TOF, refer to the User’s Guide on the CD provided with your printer. See “Using Your Printer, Top of Form (TOF).”
! To avoid TOF misalignment, always turn the printer off before turning the platen knob!
