Why doesn't paper feed from the tray to print?

Run a "half test". Put paper in the manual feed tray. Print anything. Watch the paper, when it feeds about 1/2 way into the printer, open the cover. Pull out the toner and look down at the paper. If it has the dots, replace the toner. If it doesn't have dots, the fuser is probably bad.

check on the panel of the printer if the selected paper tray is the lower tray or the upper tray put paper on both tray mark the paper so you can see which tray is being feed,

Hi the machine could be defaulted to print from the main trays if you have the same type paper being fed from the manual feed same size paper then it will automatically take it from the default trays
IF you take the paper out of the trays and put it only in the manual feed will it print and take it from the manual feed also you have to tell the machine when you use the manual feed what size and type of paper is in the manual feed once you tell it what paper and type of paper like card stock you then need to make sure when you go to print that it is set on your computer with manual feed and type of paper must match what is set on machine

I had an issue with the cassette tray paper feed. I loaded paper in the rear tray, manually used the printer properties button to make it print from the rear tray and printed from there. The next day I manually did the same thing but forced it to print from the cassette (bottom) tray. It worked fine today. It no longer thinks that there is no paper and the rollers are picking up the paper edge for proper feeding of the paper. I did not go through the roller cleaning procedure but I would do that if switching back and forth manually between trays doesn't work.

Brand New T652n lexmark printer get a paper jam every time! just opened and haven't been able to print one paper. Doesn't matter if you print from tray one or tray two. It gets stuck right after the rollers pick it up and try to send it to the toner. Any suggestions? I've tried to reseat the toner, plain paper, sized the paper correctly, I've tried just about everything I can think of! I can feed paper manually through the top tray, and it will print. But, just using the manual tray defeats the purpose of the other two trays. Anyone else having this issue?

The printer has an "alternate" feed, i.e., for envelopes and/or for special paper.

Open the door to access that "manual" tray, take some paper from the "normal" tray, and insert the paper into the "manual" tray.

Or, on the printer's controls, set the "standard" feed, rather than the "manual" feed, and press PRINT.

Could be a tab or spring broken off of the feed tray, dirty feed roller can cause that error when paper doesn't feed. Paper guide too tight so that paper can't lift to the feed roller also a possibility. Sensor above paper stack out of position.. many possibilities.

It turns out that if you read the documentation VERY carefully it says that "if the application program specifies 8.5x11 plain paper and that is what is loaded in the front cassette you cannot print from the rear tray". It turns out that this is true even if you go to the printer driver and specify "rear tray" manually. The driver disregards the setting. You can force printing plain paper from the rear tray by going to the Canon "My Printer" icon and forcing ALL printing from the rear tray. If you do this, remember to change it back. You can also print plain paper from the rear tray if you specify the "allocation" option and the paper from the front cassette runs out. You can always print from the rear tray if the application that created the print job specifies something other than 8.5x11 without resorting to the forced override, e.g. printing a .jpg or .gif or something from an application like Paintshop or Printshop, etc.

If it is not pushing the paper out of the tray, you should first try taking a soapy cleaner like fantastic or formula 109 and clean the feed rollers and see if that helps.
The paper tray also lifts up and down to feed the paper so the gear that drives the tray up and down may be broken.
Slen the rolls first. If that doesn;t last long. Say in a day or two it starts misfeeding again, the rollers will need to be replaced.

Have you tried specifying the paper type and weight INSTEAD of the tray. Set the tray properties first, then print. If you leave it on auto tray it will use the tray that matches your paper type and weight.
