Chapter 6. Print Gap Control

6.2.2.3 Gap Verify
This option allows the technician to verify that the correct gap setting has been set. Before this
operation is run, paper and ribbon are removed and a sheet of plastic shim stock is inserted into the
print zone area. The platen will close down onto the sheet and display the value of the crush point.
Using a conversion table, this crush point value can be changed to a print gap distance in inches.
If the gap is set correctly, this print gap distance should be very close to the actual thickness of the
plastic shim sheet.
6.2.3 Platen Motor Option Description
6.2.3.1 Print Gap
This option rotates the platen between the fully open position and the gap position stored in the
current configuration. The enter key operates as a toggle switch between these two positions.
6.3 Configurations
The following parameters have been added to the savable items within a given configuration: print
gap setting, detect mode setting and the detect distance.
6.4 Print Gap Display Description
One way of thinking about the display bar graph is to visualize it as a horizontal cross-section of
the print zone. The fixed left arrowhead denotes the hammer tip. The other arrowhead and
associated block characters denote the platen. The dashes in between the arrowheads denote the
print gap. As the platen closes down, the arrowhead and blocks fill in from the right. More
dashes indicate a wide gap and few dashes indicate a narrow gap. See the control panel display
examples in appendix A for further clarification.
If auto detect mode is selected, the arrowheads touching will indicate that the maximum minus
adjust range has been reached. When the rightmost arrowhead is in the middle of the display (5
blocks behind it), this indicates that the platen is at the calculated optimal print gap position (+0
adjust). When the rightmost arrowhead has no blocks behind it, this indicates that the maximum
plus adjust range has been reached.
If manual detect mode is selected, the arrowheads touching will indicate that the platen is closed
down to the absolute minimum gap (0). When the rightmost arrowhead is in the middle of the
display, this indicates that the platen is in the middle of its usable range (95). When the rightmost
arrowhead is all the way to the right, this indicates that the platen is at the largest printable gap
(190).
