Paper does not feed through, gets crumpled, jams

Check for Overload:
Ensure that you haven't exceeded the shredder's maximum capacity. Overloading the shredder can lead to jams.
Feed the paper in a steady and consistent manner, avoiding sudden force or crumpled sheets.

Switch to Reverse Mode:
If a jam occurs, switch the shredder to reverse mode. This will help dislodge any stuck paper.
Gently remove the jammed paper from the feed slot.
Inspect the Feeding Entry:
Make sure the feeding entry of the shredder is not blocked or jammed.
If there's any debris or paper stuck, carefully remove it.

Check the Cutting Blades and Gears:
The gears driving the cutting blades may be stripped or worn out.
If you suspect this, consider contacting technical support for assistance.

Impossible to answer without 'make model (what is is)' which should be written as the first three words! Fixya scripts should offer the correct category.

You can Edit that in and the question will be put back to the top of the list.

Or you can just Google

Depending on the make and model of the machine any of the following may be your problem.
Check that the jammed sheet is complete and not torn or missing fragments. Any small piece can catch in a paper feed sensor and registers a paper jam. Check that the paper pickup rollers are "tacky" to touch and do not slip easily on the fingers. If your machine is duplex capable, check the duplexer tray. If it is a laser printer, remove and return the toner cartridge and re-check function. Check the fuser is clear and look for a crumpled sheet of paper leading to the fuser. If your machine will feed paper then reports a jam look along the leading edge for marks indicating where the jam may be occurring. If you have an inkjet machine, try feeding a strip of light card BACK through the paper feed path. Above all - be patient and work it through from the paper tray to the output tray one step at a time.

Replace the Fuser.

If I load my paper at the 'proper' height, it will not feed. If I push the paper down too far, I get a 'paper jam' message. What works for me (even though it's a royal pain) is to feed 1 sheet of paper at a time. Put 1 sheet in so it's level with the top of the feed tray, then gently push it down 3/4 of an inch. That works for me. Good luck.

drum drive gear is broken that is why it is jamming

For duplex the paper feeds into the bottom paper tray, you need to make sure that paper is not stuck in the bottom area.

sounds like you have something obstructing your paper path,before inserting the tray check to see if the sensor is freely moving,hope this helps

Normal 0 I suggest you get a sheet of Card Stock (Heavy paper) and place it in the feed way. Then press the print button applying a slight amount of pressure on the Card Stock so it will feed through the printer. The reason for this is in some cases I have been able to clear the paper track of debris that was deposited there over time.
Worth a try, as I have fixed a number of printers this way, saving costly repairs.
Hope this helps. Bud

Over time the rollers get slick and hard. If one side is slick and the other edge is not, it will grab paper sideways and you get a paper jam. Get some rubbing alcohol and rub the rollers (completely all around) to get some debris removed. Some rollers require a slight rubbing with an abrasive pad.
