MACHINE WILL NOT PICK UP PAPER AND FEED IT. MANUEL FEED WORKS OK.

If your Canon IR2520 is jamming in the exit tray after initializing the machine, it could be caused by a few different issues:

• Paper tray: Make sure that the paper tray is loaded correctly and that the paper is not jammed or loaded incorrectly. Also, check if the paper tray is not overfilled or if the paper is not wrinkled.
• Pick-up roller: The pick-up roller is responsible for picking up paper from the tray and feed it to the printer. Check if it is dirty or worn out.
• Exit guide: The exit guide is responsible for directing the paper out of the machine. Make sure that it is not blocked or bent, which could cause the paper to jam.
• Fuser: The fuser unit could be malfunctioning. The fuser is responsible for heating and fusing the toner to the paper. If it is not working properly, it could cause paper jams.
• Feed rollers: The feed rollers are responsible for feeding the paper through the printer. Check if they are dirty or worn out.
• Paper jam sensor: The paper jam sensor may be malfunctioning. If the sensor is not working correctly, it may not detect a jam and the printer will continue to try to feed paper through.
• It is recommended to check the copier's manual or consult with the manufacturer's technical support to troubleshoot the problem. They may provide more specific instructions for your specific model and can guide you through the process of finding and fixing the problem.

These are general suggestions and your specific case may require different actions.

Try doing a machine self test to ensure that it is working properly.
Press OK/return to "Machine Info"
Then down arrow once to "Test Print" and OK/Return.
The machine should produce a self test printout. If the machine does not give a print out, try cleaning the paper pick up rollers at the back of the paper tray cavity. Be careful, the machine is heavy.
If a full test print happens - Your printer is working fine and the problem is at the computer end.
It's possible driver installion is faulty or incomplete and you should try re-installing the printer driver. Is it also possible that your printer paper settings are either incorrect or do not match the paper in the printer. Check and match your paper settings in the printer preferences and the paper tray.

Try cleaning the rubber paper feed rollers. If it fails to pick up the paper in a pre determined time it will show paper jam. The pick up tires must pick up paper when turning, if not the paper will not feed into the machine and it will show paper jam with no jammed paper.

Hi Margaret
Ok,the problem normaly with this model is in the feeding of the paper.For some or other reason the paper is moving to slow threw the machine and then the machine detect it as a longer size paper.

• Clean the rollers that pick the paper up and clean also the sepatation rubbers under neath the paper pick up rollers.This rubbers is called the separation pads.
• To clean this rollers,remove the cartridge and you will see the feed roller at the back.

I think what happened with the move the machine might collected dust and now the rollers are slipping.

Thanks for you support

Try cleaning the rollers located around the paper feed and making sure there is no obtructions in the way of the paper.

OK it seems to be a problem with pick up clutch and vertical feed rollers ( When you open the left door and hinge in level of cass you will see axis with the tree little rollers- clean it with alcohol or water).Pick up clutch is better to replace it FK2-1068 (europe code).

On the control panel for the printer, there's a Feed Switch button that's easily touched by accident. Ensure the Feed Switch is set to the paper source you're using (e.g. either the back or front). The graphic of the printer next to the Feed Switch button will light up to indicate the paper tray it's attempting to use.

base tray is mainly for up to 90grm paper,anything heavier
can feed for a time but tends to fault.also try and clean the
paper pick up rollers regularly.

That is the problem, machine will show printer jam if paper feed rollers fail to pick up paper when requested, your machine sounds like it needs new paper feed roller or you can clean the paper feed roller with a slightly! damp cloth.

If no jam light shows when power is turn on and machine comes to ready and then you send a job to printer and it then shows jam then it is the feed roller or sometimes the feed clutch

If on the other hand it always show jam then there is or a switch is stuck.

You have a possible paper jam or foreign matter in your roller area or feeder area, get a torch and thoroughly check inside unit, near carriages, roller and paper feeder.
