6. Print Gap Control
6.1 Control Panel Keys

PRINT GAP

(Minus)
Pressing this key once causes the print gap adjust menu to display. If six seconds have passed and
no key is pressed, the print gap adjust menu will disappear and the display will revert back to the
current online/offline status. Pressing the clear key will also cause the gap adjust menu to
disappear.
Additional key presses will decrease the print gap by approximately 0.3mils
,
. Each print gap
adjust (+ or -) key press rotates the platen by 0.9º which is one half step of the motor. Since the
print gap is determined by the rotational position of the platen, the gap change for each motor step
follows a sinusoidal curve. About the center of the platen rotation, the gap change from step to
step is fairly linear and is approximately 0.3mils. At the rotational extremes the change from each
step, however, is much less. Within the usable rotational range of the platen, the print gap ranges
from 4.5mils to 44mils. If printing does not commence within 6 seconds of the last key press, the
platen will return to the fully open position.
Once the platen control system has detected that it cannot decrease the print gap anymore, the
minus key will be disabled. This condition arises when the platen is in contact with the form and
it does not have enough torque to compress it any further.
PRINT GAP + (Plus)
Pressing this key once causes the print gap adjust menu to display. Additional key presses will
increase the print gap by approximately 0.3mils.
