Loading Envelopes Using the Envelope Cassette-E1 (Optional)
This section explains how to use the Envelope Cassette-E1.
IMPORTANT
The Envelope Cassette-E1 can only be loaded as Paper Drawer 2.

How to Use the Envelope Cassette-E1
You can load envelopes into the Envelope Cassette-E1. For information on envelopes that can be loaded, see "Available Paper Stock."
IMPORTANT
Do not forcefully move the front and side guides of the paper drawer in the wrong direction. Doing so may damage the paper drawer.
Do not print on both sides of an envelope. Doing so may cause paper jams, dirty prints, or make the inside of the machine dirty.
Do not load the following types of envelopes inside the envelope cassette. Doing so may cause paper jams, dirty prints, or make the inside of the machine dirty.
Curled, creased, or folded envelopes
Very thick or thin envelopes
Damp or wet envelopes
Torn envelopes
Irregularly shaped envelopes
Envelopes with clasps or windows
Envelopes that have already been sealed
Envelopes with holes or perforations
Envelopes with specially coated surfaces
Envelopes made of surface treated colored paper
Envelopes that are self-sticking, which use ink, glue, or other substances that can melt, burn, vaporize, or emit smells under the heat of a fixing unit (approximately 392°F). Depending on the materials used for the seal, the glue may melt under the fixing unit's heat, sealing the envelopes.
If you are printing on envelopes, empty the output tray when up to 10 printed envelopes accumulate in the tray.
Envelopes should be stored in a place away from high-temperatures and humidity.
If there is a temperature difference between the location where the envelopes are stored and the location where the envelopes are being printed, leave the envelopes in the printing location at room temperature before you use them.
Correctly match the [Paper Settings] in [Preferences] (Settings/Registration) with the size of the envelopes being loaded. Failure to do so may cause paper jams, dirty prints, or make the inside of the machine dirty.
If you want to adjust the width guides to load ISO-C5 envelopes, contact your local authorized Canon dealer.
Preparing the Envelopes
This section explains how to prepare the envelopes before loading them into the paper drawer.
IMPORTANT
If envelopes are not neatly aligned before being loaded, a problem with the paper supply or a paper jam may occur. Fix any curls or bends before loading the envelopes.

1.
Take five envelopes, loosen them as shown, and then stack them together.
Repeat this step five times for each set of five envelopes.
2.
Place the envelopes on a clean, level surface, and press all the way around the envelopes by hand, in the direction of the arrows, to remove any curls.
Repeat this step five times for each set of five envelopes.
3.
Hold down the four corners of the envelopes firmly, so that they and the sealed or glued portion stay flat.
* Flap
4.
Press the envelope in the direction of the arrows.
* Flap
IMPORTANT
Take particular care to spread the envelopes out in the direction that they will be fed.

IMPORTANT
If you use envelopes that have glue attached to their flaps, the glue may melt due to the heat and pressure of the fixing unit.
Do not print on the back side of the envelopes (the side with the flap).
If the envelopes become filled with air, flatten them by hand before loading them into the Envelope Cassette-E1.

IMPORTANT
Envelopes which have been rolled or curled must be straightened out prior to use.
Make sure that the height of the envelope stack does not exceed the height limit mark ().
The maximum height (quantity) of envelopes varies, depending on the envelope type and user operating conditions, but as a reference, 1 1/4" (30 mm) is approximately 50 envelopes.
