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 (see Figure 1)
• Envelopes with transparent windows (see Figure 2)
• Envelopes that will melt, discolour, 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%.
High humidity may cause the envelope to curl and pick up excess toner.
High humidity may also cause the envelope to seal.
• 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.
