Print GapPrint Gap Category
This category has the parameters for
setting the different aspects of the print
gap mechanism. Use the Arrow and
Enter keys to select Menu => Operator
Menu => Print Gap to get here.
Detect
When the enter key is pressed to select this parameter, the platen squeezes
against the paper at the current paper position. The resulting optimal print gap
setting is stored in the current configuration. The platen opens up fully after
this operation.
Adjust
This is where the print gap may be set, if Mode is set to Manual, or fine-tuned if
Mode is set to Auto. The final print gap value may be saved in a configuration
associated with this paper form.
Fine-Tuning when Mode is set to Auto
The upper right region of the LCD shows a number1 corresponding to the
optimal print gap determined by the detection process (the gap separating
the hammer impactors from the platen). The lower right region displays an
adjustment offset number associated with fine-tuning. When the operator
presses the “-” or “+” Print Gap key on the control panel, this number will
get smaller or larger, respectively. The range of allowed change is restricted
by the auto gap firmware. The lower left region of the LCD provides a
graphical indication of the adjustment being made.
1. This number is for general reference. The precise relationship between the displayed number and
physical distance is complex and beyond the scope of this manual.
Perf Skip
This parameter will enable the automatic perforation skip feature that will
cause the print gap to automatically increase significantly between the last line
printed on the current form and the first line printed on the next form. This
feature is useful when using heavy forms that have a large perforation “tent”
that can get hung up in the print station. The options for this parameter are
Enabled and Disabled (default).
When the Perf Skip parameter is enabled, the printer throughput will be reduced due to
the time required to automatically open and close the print gap.
