Printing on Special Paper

For printing on special types of paper, see the table below. When the paper thickness lever is set to position 4 or higher, the MULTI- PART light comes on and the printing speed is reduced.

The following table gives you general guidelines for selecting the right paper thickness lever position to match your paper:

To make sure that the printing fits within this area, always perform a sample printing test using a normal single sheet of paper before printing on envelopes.

The factory settings for International character sets (DIP switches 1-1 to 1-3), the Character table (DIP switch 1-4). and Page length (DIP switch 2-1) vary depending on the country, and are not shown in the tables above.
