Chapter 6. Print Gap Control716. Print Gap Control6.1 Control Panel Keys – Print GapPRINT GAP – (Minus)Pressing this key once causes the print gap adjust menu to display. If six seconds have passed andno key is pressed, the print gap adjust menu will disappear and the display will revert back to thecurrent online/offline status. Pressing the clear key will also cause the gap adjust menu todisappear.Additional key presses will decrease the print gap by approximately 0.3mils, . Each print gapadjust (+ or -) key press rotates the platen by 0.9º which is one half step of the motor. Since theprint gap is determined by the rotational position of the platen, the gap change for each motor stepfollows a sinusoidal curve. About the center of the platen rotation, the gap change from step tostep is fairly linear and is approximately 0.3mils. At the rotational extremes the change from eachstep, however, is much less. Within the usable rotational range of the platen, the print gap rangesfrom 4.5mils to 44mils. If printing does not commence within 6 seconds of the last key press, theplaten will return to the fully open position.Once the platen control system has detected that it cannot decrease the print gap anymore, theminus key will be disabled. This condition arises when the platen is in contact with the form andit 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 willincrease the print gap by approximately 0.3mils.
