Adjustment; Platen Gap Adjustment - Epson LQ-510 Technical Manual

4.3 ADJUSTMENT

This section describes the adjustment procedures necessary when the LQ-510 printer is reassembled or
when parts are reinstalled or replaced. These procedures are necessary to ensure the correct operation of
the printer.

4.3.1 PLATEN GAP ADJUSTMENT

Following the removal of the carriage guide shaft or carriage guide shaft levers, or if printing is abnormal,
adjust the gap between the platen and the printhead.
1. Remove the printhead. Using tweezers, remove the ribbon mask by pulling it slightly forward,
then lifting.
2. Reinstall the printhead.
3. Set the head adjust lever to the second position.
4. Set the release lever to the friction-feed position (back position).
5. Manually move the carriage to column 10.
When positioning the carriage guide shaft lever, do not try to insert tabs A and B into the notch at
the same time. The design allows only one of the tabs to enter.
