Envelopes

Most envelopes designed for laser printers 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.
We recommend that you print a test envelope to make sure the print results are what you want.
