Oki 390, 391 manual Expanded Printhead Gap

Expanded Printhead Gap

Your printer can be used for dedicated bottom-feed printing on extra-thick multi-part forms. Extra-thick multi-part forms range from 0.017-inch (0.43 mm) to a maximum of 0.03 inch (0.79 mm). To print on extra-thick multi-part forms, you engage the expanded printhead gap feature. This expands the head gap settings for extra-thick forms and heavy card stock. It also increases the impact strength of the pins in the printhead.

!CAUTION! Once the expanded printhead gap is engaged, you cannot print on single sheets without

changing the gap back. If you try to print on single sheets without adjusting the printhead gap, you can damage the printhead and void your warranty.

To disengage the expanded printhead gap, reverse the following steps.

To engage the expanded printhead gap:

1Turn the printer off.

2Remove the access cover and the pull-up roller assembly.

3Move the printhead to the center of the platen.

4Remove the ribbon cartridge.
