In the Stack Bypass Tray
If you are making prints on transparencies, labels, nonstandard-sized paper, or envelopes, load them into the 
stack bypass tray.
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 × 127 mm to 216 × 356 mm )
Paper Weight: 16 to 47 lb (60 to 176 g/m
2)
Paper which has been rolled or curled must be straightened out prior to use, to allow the paper to feed smoothly through the stack 
b ypass 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 t
 o 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  for copying, you cannot use the 1-Sided to 2-Sided, 2-Sided to 2-Sided, Frame Erase, or Image 
Combination mode. (See “Copy,” in the e-Manual.)
I
 f you select , , , ,  for copying or printing, you cannot use the Collate, 1-Sided to 2-
Sided, 2-Sided to 2-Sided, Frame Erase, or N on 1 mode. (See “Copy,” in the e-Manual.) Envelopes may be creased in the printing process.
For high quality printouts, use paper recommended by Canon.
For more information on paper types that can be used with this machine, see “P
 aper Requirements,” on p. 2-7.

1 
Open 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). (See “Setting Paper Size and Type,” on 
p

. 2-20.)
2 
Adjust the slide guides to match the size 
of the paper.
If you are feeding large size paper, pull out the 
auxiliary tray, and extend the tray extension.
3 
Load the paper into the stack bypass tray.
Insert the paper stack as far as it will go.
When you print on paper which has logos or 
patterns already printed on it), see 
“Relationship between Original Orientation 
and P
 reprinted Paper Output Chart,” on p. 2-
24.
■  Before inserting paper
①
  When you use the stack bypass tray to 
make copies, straighten out curled paper 
prior to use, as shown below. Curled paper 
may cause a paper jam.
②  If there is difficulty in straightening out 
curled paper, curl the front edges of the 
paper upward, as shown below.

■ To print on the back side of preprinted 
paper
①

  Load the preprinted paper face up into the 
stack bypass tray, as shown in the 
illustration below.
The screen for selecting the paper size appears.
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.
