Stops or starts printing, if any print data exists in the input buffer. (Turns
pause mode on or off.)
Advances the paper line by line according to the set line spacing while the
printer is ready to print or paused by the PAUSE button. Holding down the
button for about one second advances the paper to the next top of form
(TOF) position. This button is also used to load the paper from the push
tractor of the selected paper path when the printer is in the paper-out state.
Enables tear off mode and advances the paper to the tear off position. This
button functions only when the printer is in pause mode. The tear off
position can be adjusted using the MICRO FEED buttons. The adjusted value
is stored in the EEPROM on the main board when the printer is turned off.
Adjusts the paper position, including the top of form (TOF) and tear off
positions. The forward MICRO FEED button (A) advances the paper in 1/216
inch increments and the backward MICRO FEED button (v) feeds the paper
backward in 1 /216 inch increments.
Enables top of form (TOF) setting mode, so that the TOF position can be
adjusted using the MICRO FEED buttons. This button functions only when
paper is loaded into the printer using the LF/FF LOAD button and the
printer is in pause mode. In TOF setting mode, the PAUSE LED is lit and the
TOF LED blinks.
Selects a character pitch of 10,12, or 17 cpi.
Selects the front or rear paper path. If there is paper in the current path and
the printer is in pause mode, the paper is fed backward to the tractor. Then,
the selected paper from the other tractor is fed to the
TOF position. If all the
paper in the current path is not fed backward to the tractor by the single
22-inch (55.9-cm) backward feeding sequence, make sure your previous
print job is tom off and press the PAPER SELECT button again until the
current path is empty.
