Paper Does Not Feed Properly

Content Id: 8201023400


Issue

Cause and solution

Check 1: Make sure of the following when you load paper

When loading two or more sheets of paper, flip through the paper before loading.

When loading two or more sheets of paper, align the edges of the sheets before loading.
When loading two or more sheets of paper, make sure that the paper stack does not exceed the paper load limit. However, proper feeding of paper may not be possible at this maximum capacity depending on the type of paper or environmental conditions (either very high or low temperature and humidity). In such cases, reduce the sheets of paper you load at a time to less than half of the paper load limit.
Always load the paper in portrait orientation, regardless of the printing orientation.
When you load the paper on the Rear Tray, load the paper with the print side facing UP and slide the Paper Guides to align with the both sides of the paper.

Loading Plain Paper / Photo Paper

Caution

If you cut plain paper into small size such as 4" x 6" / 10 x 15 cm, 4" x 8" / 101.6 x 203.2 mm, 5" x 7" / 13 x 18 cm, or 2.16" x 3.58" / 55.0 x 91.0 mm (Card size) to perform trial print, it can cause paper jams.

Caution

We recommend Canon genuine photo paper for printing photos. For details on the Canon genuine paper, see [ Media Types You Can Use ].
You can use general copy paper. For the page size and paper weight you can use for this machine, see [ Media Types You Can Use ].

1. Prepare paper.

Align the edges of paper. If paper is curled, flatten it.

Caution

Align the edges of paper neatly before loading. Loading paper without aligning the edges may cause paper jams.
If paper is curled, hold the curled corners and gently bend them in the opposite direction until the paper becomes completely flat. For details on how to flatten curled paper, refer to [ Paper Is Smudged/Printed Surface Is Scratched ].

2. Load paper.

(1) Open the Paper Support, and open the support as an extension.

(2) Open the Paper Output Tray gently.

(3) Slide the Paper Guides (A) to open them, and load the paper in the center of the Rear Tray WITH THE PRINT SIDE FACING YOU.

(4) Slide the Paper Guides (A) to align them with both sides of the paper stack.

Do not slide the Paper Guides too hard. The paper may not be fed properly.

Caution

Always load paper in the portrait orientation (B). Loading paper in the landscape orientation (C) can cause paper jams.

Caution

Do not load sheets of paper higher than the Load Limit Mark (D).

Caution

The machine may make operating noise when feeding paper.

If the paper tears in the Rear Tray, see [ Paper Jams ] to remove it.

If there are any foreign objects in the Rear Tray, be sure to turn off the machine, unplug it from the power supply, then remove the foreign object.
