6.2 Menu Structure
To configure normal platen operation, Print Gap has been added as a category under the Operator
menu. Within the Print Gap category are the following parameters: Detect, Adjust, Reset, Mode
and Detect Distance.
To calibrate the platen system, Platen, Print Gap and Gap Verify have been added as options under
the Cal-Engine parameter. These options are only accessible when tech access is enabled.
To test the platen motor, Print Gap has been added as an option under the Motors parameter.
6.2.1 Basic Platen Parameter and Option Descriptions
6.2.1.1 Mode
The two options within this parameter are auto or manual.
In auto detect mode, the adjustment range about the calculated optimal gap will be restricted. The
minus adjustment will be limited to a range that does not allow the gap to get tight enough to stall
the shuttle system. The plus adjustment will be limited to a range that does not allow for
excessive missing dots.
In manual detect mode, the adjustment range of the platen is 0 to 190.
If auto is selected, print gap detection will be preformed during the first platen close operation
after a paper-out condition.
The following events will cause the platen to close: TOF key press, detect key press, print gap
adjustment key press or the start of a print job. Subsequent platen closings will not trigger a print
gap detection operation until the next paper-out condition is detected. The calculated optimal gap
setting for each print gap detection is compared to the value stored in the current configuration. If
it is not significantly different, the previous gap setting with adjustment will be retained.
In the zero-tear printing mode, print gap detections will be tied solely to the TOF key. This is due
to the fact that the paper-out sensor is non-usable in this print mode.
The resulting optimal print gap setting and adjustment range will then be stored in the current
configuration. From this point on, when the platen is commanded to close, it will go to this stored
setting.
If the platen is unable to close down to this gap setting, either a print gap fault or a platen motion
fault message will be displayed. This scenario can be caused by a paper jam within the print zone.
