Appendix
Do not attempt to print on any of the following types of envelopes. These
may cause damage to your printer.
•Envelopes with clasps, snaps or tie strings (as illustrated on left below)
•Envelopes with transparent windows (as illustrated on right below)
•Envelopes that will melt, discolor, scorch offset or release hazardous
emissions when exposed to 200°C (392°F) for 0.1 second
•Envelopes that use encapsulated types of adhesive that do not require
moistening but rely on pressure to seal them
Always test a sample of the envelopes you are thinking of buying. Confirm
that the envelope performs acceptably.
■ For best printing results
•Avoid printing in high humidity i.e., above 70% RH.
High humidity may cause the envelope to curl and pick up excess toner.
High humidity may also cause the envelope to seal.
•Avoid printing below 10°C (50°F) with less than 30% RH.
Low temperature with low humidity may cause light printing.
•Print only one envelope at a time.
Envelope storage is very important. Store them away from moisture and
humid air, where they can lay flat and their edges won’t be bent or
damaged. The humidity should not exceed 70% RH.
The bidirectional parallel interface is based on the IEEE P1284-C standard.
If your computer has a bidirectional parallel port, the printer driver and
printer can take advantage of faster data transfer.
