Diagnostics and Print Tests

Adjusting the Printhead Gap

If the print from the test is light, the gap between the printhead and the paper may be too large. If the print is smudged, the gap may be too small. You can easily adjust the printhead gap.

1.Open the cassette cover and remove the ribbon cassette.

2.Move the anti-rotation bearing to the right to decrease the gap, or move it to the left to increase the gap.

3.Put the ribbon cassette back in the printer and place the cassette cover back on the printer.

4.Run the general print test again to be sure that the adjustment is correct. Repeat steps 1-3 if necessary.

See “General Print Test” earlier in this section.
