When using overlapping multi-part forms, do not use the paper select (change tractors) or tear

offfunction; to avoid a paper jam, it is important not to feed overlapping multi-part forms

backward.

Notes:

Rough multi-part form binding causes paper jams.

1.

2. The

multi-part form sheets should be bound together with spot gluing (dotted paste), paper
stapling (mechanical staking), or tape stitching. Forms joined with spot gluing are
recommended for the best printing quality.

3.

For multi-part forms joined with dotted paste, the form sheets can be joined on either a single

side or both sides. Figure 1-14 shows the recommended paste positions.

The printer detects the right paper edge and determines the right end of the printable area. This

disables printing in areas where there is no paper.

The printer measures the paper thickness each time paper is loaded. The distance between the
printhead and the platen is automatically adjusted to match the paper’s thickness and obtain the
best print quality.
