ADJUSTING THE PRINTING GAP
The distance between the print head and the platen can be adjusted to
accommodate different paper thicknesses. The adjustment lever is located at
the left side of the printer. Pushing the adjustment lever towards the rear of
the printer narrows the gap; pulling it towards the front of the printer widens
the gap.
There are five positions, and you can feel the lever clicking into each position.
The second positon from the rear (marked with “•”) is the one most commonly
used for single sheets of paper.
Try different positions until you get the best printing results.
NOTE:Printing with an inappropriate gap may drastically shorten the life
of the print head.
