The printer generates coarse test patterns using hammer lead times from several shuttle

Step 7. Examine each line of the printed output for each lead time and select the one that has
the best dot placement, then scroll to that setting on the Control Panel and depress the
ENTER
key to select it.

times and the calibration routine is over.

heavy forms installed on the printer.
2.3.3.1.2 Shuttle Stroke
Guides the operator through a procedure used to calibrate the shuttle stroke so that the space
between hammers is optimal.
2.3.3.1.3 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.
