How can i get my pixma mp 620 printer to print on both sides of the paper

I have a problem cannon Pixma MP 287 print paper can not enter when printed , if the paper can be rolled up

printer supports it. just you have to goto printing preferences or printer properties and set rear tray to accept glossy paper. it will accept size of paper ur using. so give the actual size.

Go into maintenance tab in the printer file.( Control panel, hardware and sound, printers, your printer, select printer preferences, maintenance) Select roller cleaning and follow instructions. That might help.

mine is the same. did you find a solution to this problem?

Hi there,

Loading Paper into your Canon MP 160 Pixma.

A) Loading Paper :
Follow this procedure:
1) Open the Paper Support, then pull out the Paper Support Extension.

2) Place a stack of paper (print side up) in the Auto Sheet Feeder, pinch the Paper Guide and adjust it to the left side of the stack.
* Set the Paper ThicknessLever to the correct position for the paper.
Note : Set the Lever to the left for most paper. When the Lever is set to the right, the confirmation message appears before the machine starts printing.
Important : Make sure the stack does not exceed the Load Limit Mark.


B) Loading Envelopes
Follow the following steps:
1) Open the Paper Support, then pull out the Paper Support Extension.

2) Prepare the envelopes for loading.
Important : * Press down firmly on the edges of the envelopes to make the folds crisp. Also, press firmly on the area that corresponds to the edges of the back flap.
* Remove any curling by holding the edges diagonally and bending them gently.
* If the edges of the envelopes are inflated or curled, place the envelope on a flat surface. With a pen, press down while moving it from the center toward the edges of the envelope.
* Ensure that no curl or puff exceeds 1/8 in. (3mm).

3) Place the stack of envelopes (print side up) in the Auto Sheet Feeder, pinch the Paper Guide and adjust it to the left side of the stack.
* Load the envelopes in the Auto Sheet Feeder with the short side down.
* Set the Paper Thickness Lever to the right.

Important : Make sure that the stack does not exceed the Load Limit Mark.

Hope this helps. PLease rate my response.
Thanks
Have a good day.

I removed a paper jam.

Had the same problem. Turn off the printer (completely) and turn it on again. That fixed the problem for me (without even touching the paper tray!)

Download the manual for the MP 620  instruction. 
780 and 620 models use second link and look up  your own.

This is definitely a mechanical problem. You might want to at least partially take the printer appart and inspect it very thoroughly if you haven't done so yet. Did you have any paper jams before? Sometimes when you remove a paper jam the sheet rips and you end up with some shreds of paper lodged in the printer mechanism causing more jams. Another possibility might be cracked or bent paper guides, or simply dirty rollers (these you can clean with alcohol).

i have a canon pixma mp 500 and a new computer misplace my disc and can install
