Head Gap Adjustment
This printer has a mechanism to automatically adjust the head gap after measuring the paper
thickness. As there is variance from printer to printer, the head gap of each printer is adjusted to the
optimum setting at the factory prior to shipment.
Operating Procedure
(1) Select the rear tractor paper path and feed a 15-inch wide sheet of paper.
(2) While simultaneously holding down the [LF] and [RLF] keys, turn on the printer. The printer will
enter the head gap adjustment mode.
(3) The LCD will have the display shown below. Select Front or Rear using the [
← ] key (SPEED) or
the [ → ] key (TEAR OFF).
The front head gap adjustment setting is used for front tractor feed and manual feed.
The rear head gap adjustment setting is used for rear tractor feed and cut-sheet feed
(CSF).
(4) Press the [ ↑ ] key (LF) to display the numeric gap setting. Press the [ ↓ ] key (RLF) to select the
current setting. NOTE: the current setting is indicated with an asterisk (
*
).
(5) Press the [
↓ ] key (RLF), and the printer will print out the gap adjustment pattern.
The figures to the left of the gap adjustment pattern represent the [gap settings].
The figures on the right represent the [number of pulses from home (top)].
After the printing is complete, the LCD displays the current gap adjustment setting, as
shown below.
