Hi -
According to the user's guide, the CM2320 supports the following sizes in Tray 1, Tray 2, and Tray 3:
- Envelope #10 105 x 241 mm (4.13 x 9.49 inches)
- Envelope DL 110 x 220 mm (4.33 x 8.66 inches)
- Envelope C5 162 x 229 mm (6.93 x 9.84 inches)
- Envelope B5 176 x 250 mm (6.7 x 9.8 inches)
- Envelope Monarch 98 x 191 mm (3.9 x 7.5 inches)
With the following limitations:
- Up to 90 g/m2 (24 lb)
- Tray 1: up to 10 envelopes
- Trays 2 and 3: up to 30 envelopes
- Side to be printed on faceup, with the stamp-end at the back of the tray
and the following guidelines on media handling:
DO
- Store envelopes flat.
- Use envelopes where the seam extends all the way to the corner of the envelope.
- Use peel-off adhesive strips that are approved for use in laser printers.
DO NOT
- Do not use envelopes that are wrinkled, nicked, stuck together, or otherwise damaged.
- Do not use envelopes that have clasps, snaps, windows, or coated linings.
- Do not use self-stick adhesives or other synthetic materials.
With the printer driver and application, one can select a specific envelope size and source tray to match the media loaded into the device.
Does that information help? If not, a more detailed description of the issue or capabiity information is needed for would be helpful.
Thanks!
