ADJUSTING THE PRINTING GAP
The distance between the print head and the platen can be adjusted to accommodate different paper thicknesses. To make this adjustment, remove the top cover. The adjustment lever is located at the left side of the printer mechanism. Pushing the adjustment lever backwards narrows the gap; pulling it forwards widens the gap.
There are five positions, and you can feel the lever clicking into each position. The second position from the rear is the one most commonly used for single sheets of paper. Try different positions until you get the best printing results. (Do not set the lever out of the marked positions.)
