Paper fed won't catch the paper - Brother DCP-7020 All-In-One Laser Printer

sometimes copiers have problems if the paper got damp, the paper may have a slight curve to it and when the paper is fed into the rollers it doesn't feed straight and it gets hung up or if there was a previous jam, there could be a small piece of paper hiding and catching the new sheet,,,,, or possibly a bad batch of paper.

Receipt Feeds,
But Nothing Is
Printed On It Not using thermal paper. Ensure thermal paper is being used. Thermal paper loaded upside down. Ensure thermal paper is being fed from underneath the roll, as it will only print on one side of the paper.

Feed the paper through the slot located just under where the roll is sitting. Once you have fed it through as far as you can, press the arrow button (the up arrow) on your calculator until it catches the paper & feeds it through the machine.

open the printer tray and remove the paper jam

...look at the printer manual to remove jams. Some time you may have to remove the difuser to get rid of them. Depending what type of printer you have. Remember you can go on line to download the manual if you don't have one available. Check if the paper is catching excesive mousture and that the roller that catch the paper have been given proper maintenance. Tks.

clean the rollers that help the paper feed into the machine with a clean cloth and rubbing alcohol...

The paper is not feeding from the paper tray. The loud click is alarming, but not the problem. Check the adjustments in the paper tray. The left and right guides should be snug, but the rear guide should give between a 1/16 inch and a 1/8 inch of free play.

To check, press the purple lever at the right front of the tray. The leading edge of the stack of paper in th etray should rise out of the tray so that the top piece of paper can be fed into the drum assembly. If the stack does not rise evenly, or will not rise, the rear adjustment is the problem.

You can inspect the springs in the paper tray by removing the plastic cover that is above the white translucent roller in the tray. To do this turn over the tray and release the catches with a little screwdriver. I do not think there is a missing spring. While you have the cover off clean the lnt from behind the roller.

what do you mean too tight ?????????
check the path and make sure there is nothing catching the paper

If your location is too humid, paper can stick together. If it's too dry, static electricity can also hold paper together.

Incorrect paper thickness / weight can also cause this.

It's a good idea to 'fan' the paper before inserting it, and make sure the paper thickness/weight & room humidity levels agree with those in the specs at the back of the printer manual.

You can see into the feeder area on some printers. If it looks like the rollers are moving on both sides, use clean, flat paper, and avoid humid conditions. Sometimes humidity can cause slight curls on the edge which interfere with the grippers.
If the grippers are not working on both sides, you may need a repair.
