Note the following points when using the stack bypass tray:

• Paper Quantity: one to approximately 100 sheets (20 lb (75 g/m²)).
• Paper Size: 3" x 5" to 8 1/2" x 14" (76.2 x 127 mm to 216 x 356 mm )
• Paper Weight: 16 to 47 lb (60 to 176 g/m²)
• Paper which has been rolled or curled must be straightened out prior to use, to allow the paper to feed smoothly through the stack bypass tray (allowable curl amount: less than 3/8" (10 mm) for normal paper, less than 1/4" (5 mm) for heavyweight paper).
• Depending on the paper storage conditions, it may not be possible to feed some paper into the stack bypass tray. In this case, set the amount of paper to less than 50 sheets (20 lb (75 g/m²)).

Do not load different size/type paper at the same time.

If you load multiple sheets of heavyweight paper into the stack bypass tray, a paper jam may occur depending on the type of heavyweight paper. If this happens, load only one sheet of heavyweight paper at a time.

When printing on special types of paper, such as heavyweight paper or transparencies, make sure to correctly set the paper type, especially if you are using heavyweight paper. If the type of paper is not set correctly, it could adversely affect the quality of the image. Moreover, the fixing unit may become dirty and require a service repair, or the paper could jam.

If you are printing on envelopes, do not allow more than 10 envelopes to accumulate in the output tray. Always empty the output tray once 10 envelopes have accumulated.

If you select <Custom Size> for copying, you cannot use the 1-Sided to 2-Sided, 2-Sided to 2-Sided, N on 1, or ID Card Copy mode.

If you select <COM10>, <Monarch>, <DL>, <ISO-C5>, <ISO-B5> for copying, you cannot use the 1-Sided to 2-Sided, 2-Sided to 2-Sided, N on 1, or ID Card Copy mode.

You cannot use <Custom Size> when you print from a USB memory (Direct Print). (Only for the Color imageCLASS MF9280Cdn)

Envelopes may be creased in the printing process.

For high quality printouts, use paper recommended by Canon.

• If the paper drawer is not set, you will not be able to print or copy from the stack bypass tray.
• If the paper size you are going to load into the stack bypass tray is different from the paper size stored in stack bypass tray Standard Settings, set stack bypass tray Standard Settings to 'Off' in Common Settings (from the Additional Functions screen).

If <Stack Bypass Paper (Std.)> in <Paper Settings> is set to <On>, you can load only the specified size and type of paper.

• When loading paper into the stack bypass tray, align the paper stack neatly between the slide guides. If the paper is not loaded correctly, a paper jam may occur.
• If you are printing on heavyweight paper or envelopes using the stack bypass tray, and find that the paper or envelopes are not being fed smoothly or evenly through the stack bypass tray, remove the paper or envelopes, curl the feeding edges upward approximately 1/8" (3 mm), and then reload the paper or envelopes. Curling the feeding edges enables the rollers to grip the paper or envelopes as they are fed into the machine from the stack bypass tray.
  
  

• If there are instructions on the paper package about which side of the paper to load, follow those instructions.
• When the paper is loaded into the stack bypass tray, the side facing down is the one printed on.
• If problems, such as poor print quality or paper jams occur, try turning the paper stack over and reload it.

Take particular care to spread the envelopes out in the direction that they will be fed.

• 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 stack bypass tray.
  

• The stack bypass tray can hold 10 envelopes at a time.
• Envelopes may be creased in the printing process.
