Envelopes

Most envelopes will be suitable for your machine. However, some envelopes may have feed and print-quality problems because of the way they have been made. A suitable envelope should have edges with straight, well-creased folds and the leading edge should not be thicker than two sheets of paper. The envelope should lie flat and not be of baggy or flimsy construction. You should buy quality envelopes from a supplier who understands that you will be using the envelopes in a laser machine.

Envelopes can only be fed from the MP tray. Do not print envelopes using duplex printing. We recommend that you print a test envelope to make sure the print results are what you want before you print or purchase a large quantity of envelopes.

Check the following:

„Envelopes should have a lengthwise sealing flap.

„The sealing flaps should be folded crisply and correctly (irregularly cut or folded envelopes may cause paper jams).

„Envelopes should consist of two layers of paper in the area circled in figure below.

„Envelope joints that are sealed by the manufacturer should be secure.

„We recommend that you do not print within 15 mm of the edges of envelopes.
