Imagistics sx 2100 paper jamming

General tip: If the paper tears when you pull a jam out of the printer, spread the paper out and make sure you have all of the pieces. A small shred left inside can cause another jam.

"I also can the drum" - does this mean you discarded the printer cartridge? I've never seen a cartridge cause a jam. Usually an accordion-fold jam in this area is the result of the fuser rollers not turning or a torn fuser sleeve. A jam without an accordion fold indicates that the paper did not make it into the toner deposition area soon enough - this could be a problem with the pickup roller or the next set of rollers. Worn or dirty rollers can work intermittently before they quit completely.

Also, check the paper detection flag to make sure it isn't hanging up (this is a black plastic tab that sticks into the paper path just before the paper goes under the cartridge, and is pushed up or down by the paper). Look for the U-shaped optical detector that is interrupted by this flag, and make sure it isn't blocked by foreign material.

Problem: Paper jams as it exits printer, starts out as intermittent and gets progressively worse. Paper has accordion folds at bottom.

Cause: Fuser drives paper out faster than the worn out exit rollers can push it out of the printer. This causes the paper to fold up.

Solution: The rubber treads in the rollers wears down, making them smooth. Sometimes, they are aged, which also gives them a smoother rounded texture, causing jams. The quick fix is to liven up that roller with a mixture of alcohol and soap. Damp a rag with the solution and wipe the rollers clean with it. That's make them more pliable. If problems persist, the rollers need to be replaced.

That sounds like the fuser stripper fingers and or the hot roller need to be replaced.

Open the door where the toner cartridge is, and push the clear key and look at the display where it will say reset no press 1 yes press 2. That should do it.

This will happen if the belt isn't properly settled, so that the sheet of paper enters at a slight angle and jams. The roller loader will then fold it into an accordion shape.

While I don't understand how the printer let you print (the sensor should have raised an alarm), you could try extracting the belt unit and re-settling it. Verify the blue retainers have been fully rotated (one eighth turn clockwise) and the handle is completely down.

When you clear the paper from the machine at the fusing unit, you can see 8 pawls, it looks like a hook but in a flat design. They should be touching the heat roller ( each has a spring to make it flexible ). If one not touching the heat roll it will caused the paper stuck to it so you will have the accordion paper jam.

I have found that with laser printers that have an occasional "crinkle" problem that "fanning" the paper does alleviate the problem ... but it will not if there is an actual feed/hardware problem with the rollers

Hello Al_edee,

Try to look at the fuser, when it's cooled down, if there are remains of old or stuck paper in it or to exchange the fuser.

Kind regard,

I am assuming that you have an jammed paper in the back door or an accordion jam in which the paper is all folded up or crinkled. if that is the case the printer needs the output assm replaced (hp part number rg5-0886). which is pretty simple take out screws for top cover remove top cover at rear of machine once cover is off there are two taabs holding assm in place depress tabs rotate assm slighlty and lift out of place reverse process to reinstall takes less than 5 minutes to complete.
