Verify AFTA calibration, using single-part forms
1. Set the operator panel menu item FIXED=1.
2. Load single-part, 20 lb (80 g/m
2
) forms into the printer, using the Load key. Note the wheel position.
3. If the wheel position for FIXED=1 is different than the number you noted at “A” during the procedure entitled
Verify AFTA operation, using single-part forms, run T&D08 Set the adjustment value to
0
, and STORE.
4. To verify that the wheel position is now correct, repeat the Load operation using single-part forms, with the
settings AFTA=0 and FIXED=1. The wheel must go to the same position.
Verify printhead needles
To verify that all the printhead needles are functioning, run T&D12. The use of the “Printhead Wire Test” pattern is
shown in Table 24, and is described in line 4 and line 11 of Table 23.
Line 4 - If any of the needles are not functioning or if the xxB line segments are not lower than the xxA line
segments, replace the printhead.
Line 11 - If you notice ink smearing on a printout such as with T&D12, Line 11, replace the printhead.
Note: You cannot correct these conditions by changing the AFTA print gap.
Print quality check: Perform this check only after completing the Power Off Check, then the Power On Check.
Print darkness check
This procedure creates print samples at various, increased-gap settings to disclose if the character darkness is
correct. If the print darkness is not correct, you will use T&D08 to adjust the print gap and correct for character
darkness.
1. Ensure you have a new or nearly new ribbon cartridge loaded in the printer.
2. With printer turned on, load white, single-part, 20 lb (80 g/m
2
) paper.
3. Save for later use in Analyzing samples any print samples you create during any of the following steps.
