Service checks and adjustments

Automatic Forms Thickness Adjustment (AFTA)

Follow this procedure to set the correct print gap without using a feeler gauge. This procedure applies to printers
NOT yet disassembled. If a printer has been disassembled (shafts have been removed, and so forth) perform the
Print Head Gap Service Checks before using this procedure.

Preparation

CAUTION:
<2-25> High temperature; switch off the printer and allow at least 20 minutes for parts in this area to cool before
handling.
v If needed, with a dry cloth or toothbrush, clean the white surfaces around the print head needles to clear away
any excessive ink.
