6.2.1.4 Reset

When the enter key is pressed, the current gap position is set to 190. The usable / printable
rotational range of the platen is 171º which equates to values of 0 through 190 on the print gap
adjust display. The reset value of 190 equates to a gap of approximately 44mils. The reset
function is useful for the user that does not wish to operate in the auto detect mode, but is unsure
of where to set the gap. Reset will put the gap at a known position (wide) where the user can then
begin honing in on the optimal gap.
If manual detect mode is selected, the allowable adjustment range will be set to –190 / +0. If auto
detect mode is selected, a print gap detection will be run the next time the platen is commanded to
close.

6.2.1.5 Adjust

This parameter works similar to that of pressing the dedicated platen adjust keys. The only
difference is that the display does not time-out after six seconds of inactivity.

6.2.2 Platen Calibration Option Descriptions

6.2.2.1 Platen

This option calibrates the platen sensor to the platen motor. In order for the platen sensor
calibration to work properly, paper and the ribbon cartridge must be removed. The software,
however, checks for the presence of these items and will display an error message and not start the
calibration until they have been removed.
When the enter key is pressed the platen motor will step through its entire rotational range. At
each step the sensor reading will be recorded. This process takes approximately 30 seconds and
its progress is indicated by an increasing bar graph on the control panel. Once completed the
platen will return to the fully open position. If errors are found in the table after the calibration has
completed, the table is erased and "Platen Sensor Fault" is displayed on the front panel.

6.2.2.2 Print Gap

This option allows the platen to be aligned to the hammer bank. When the enter key is pressed the
platen goes to a value of 54. At this point, the technician will align and distance by approximately
13mils the platen from the hammer tips. This is achieved by turning the screws on the adjust side
plates. Once this is complete, the enter key is pressed again and the platen returns to the fully
open position.
The print gap calibration and the platen sensor calibration need only be run during final assembly
of the printer and anytime a platen is replaced. If a hammer bank is replaced, only the print gap
option needs to be run.
