Canon PC770 - paper tray wouldn't slide in all the way
Same problem as previous users. Large spring visible near the right rear of the paper tray slot. When I turned the copier on its back, a piece of broken plastic fell out - just the right size to fit the end of the spring. Loosened the bottom cover to get my hand in and pulled out the spring. Copier is working again. I think the spring is there to counter-balance the top when you raise it to replace toner cartridge. Now I have to hold the top up with one hand while replacing the cartridge with the other.

Re: Canon PC770 - paper tray wouldn't slide in all the...
Thats right that spring help to counter balance the top,the pease of plastic is to keep the spring in place.There are 2 spings that support the top.That plastic is not so expensive but to install the new plastic and spring is a very big job and it can be expensive.It normally takes me 3 hours to replace.The mashine can work normally it is only a hassel when you want to replase the toner .

Unplug the power cord of the printer and open the cover to reveal the carriage assembly.
Squeeze the two levers beneath the paper tray together to remove the tray.
Slide the carriage assembly from the left side of the printer to the middle where you have easy access to it. If the carriage assembly will not slide.
Push down the large black bar located directly above the rollers and then release it so that it springs back up. Now attempt to slide the carriage assembly to the right again. If it still does not slide.
Locate the flat black component found directly below the rollers in the tray compartment. It should be lying flat, parallel with the base of the printer. If it is pointing upward, push it down.
Slide the carriage assembly over to the right once all of the above parts are in their correct positions.
Lift the actuator arm, which is directly above the white and/or gray gear assembly at the left side of the printer. The actuator arm is thin strip of black plastic that is approximately 1 3/4 inches long and 1/3 inch wide. Lifting it and releasing it should restore it to its proper position.
Put the paper tray back in the printer. With the cover of the printer still open, plug in the power cord and turn on the printer.
Press and hold "Resume," then close the cover of the printer.
Load the envelope against the right side of the back paper tray.
Load with the address side facing UP and the rear flaps DOWN on the left.
Pinch the Paper Guide and slide it against the left side of the envelope.
Set the Paper Thickness Lever to the right, return to the left after finishing printing.
The Paper Thickness Lever is located inside where the paper come out of printing.
Specify the settingin the printer driver.
Select Envelope in Media Type
Select DL Env. or #10 Env.
Select Landscape in Orientation.
The MX310 is a straight through printer. So you put the paper in the rear tray after opening it. Pull out the paper support and adjust the lever for the paper thickness to match your paper specifications. The lever goes to the left unless printing envelopes and T-shirt transfers. Also pull out the paper output tray and set the output tray extension.
Align the 4 corners of the paper stack (if loading more than one sheet) and bend to uncurl the paper (if needed) before inserting in the rear tray. For photo paper and other pages with a print side and a back, place the pages with the print side facing up. Align the paper against the right side of the rear tray and then pinch the paper guide and slide it to the left side of the paper stack. Make sure to adjust the paper size to match in the computer's printer properties (paper size) or in the copy settings on the all-in-one before either printing or copying.
Just fixed this problem on mine. Need to remove the covers, watch these 2 vids to see how.. http://www.youtube.com/profile?user=martop49#p/u/1/iQdHDR6po80
on the right side where the on switch is, near the hinge is a little
switch with 2 yellow wires, it's probably broke. Pull the 2 wires out
and solder or twist them together, then put everything back together.
It will now assume the door is always open. Jobs a good'n :)
After numerous attempts, the drawer finally slid in and worked --- until today.
New problem - drawer wouldn't come out and indicator showed the paper was out when machine had paper.
Removed screws from bottom of copier - couldn't completely remove the metal plate, but was able to pull it out enough to allow the paper drawer to be removed. Only thing that could be seen as potential problem was a spring hanging down the back that did not seem to be attached to anything. (heavy duty, about 7" long and 1/2 inch diament)
Removed screw, replaced screws in bottom plate - drawer slid in fine - turned on and ran copies just fine. Don't know what the spring was for - but copier is working for the moment.
