Paper jam My printer says it's jammed and I'm not sure how to check it? All the paper that went through it, came out. I've turned it off and back on as well as shut the computer down.

Some of the Ink Jets have a cover in the back of the printer that you have to turn a lock to remove and you could have some paper stuck back there.

Please help with cannon PIXMA MP150 printer problem, when trying to print, It reads that paper is jammed but I've checked several times and no paper is jammed. Printer will not print due to this...


Hello and Welcome to FixYa!

Paper jam means their may be small bit paper jam in side
, actually there are some "micro sensors" that detect a paper jam. There will be tiny piece of paper inside those sensors, thus tripping the sensor and paper jammed keeps coming up.
To solve this first of all Open printer cover and check to make sure no paper or foreign objects obstructing the printer feeder
, If you become sure that now really there is no paper, dust or foreign objects then Turn the printer off, and disconnect the AC power-cable. Open the printer cover & now give the printer a "blow-job" by compressed air.
If still problem exist then best & final option is to just contact to any Canon Printers service provider.

I hope this solution helps you
Thank you for using FixYa!

Our printer is not picking up the paper from the tray and is saying it is jammed. There is not jam.


Hi there !

Is your printer had jammed before and it stop printing in the middle of printing? For some reasons, paper can jammed due to printing interruptions, printer turn off, improper loading or feeding of paper, roller feeder had problem and others.

If jams before and paper have let inside the printer, please do the following first:

1. Check th paper tray, see inside if the paper is jammed inside that compartment. If there is paper jammed, remove, turn off your printer and turn on. This will solve your problem.

2. If not, open the printer cartridge door, remove the toner cartridge and look for paper jammed inside. If these is paper inside, remove it, turn off the printer and turn it on.

3. If you cannot see the paper jammed inside, the paper maybe inside the heating area. To remove paper, just turn off your printer and turn it on to roll over the paper jammed inside of it.

4. If the printer is blinking and saying there is paper jammed. You have to check the cartridge toner by opening the cartridge door, remove the cartridge and return it back but be sure it is well firmly fitted.

If following the 4 diagnostic procedure and you cannot locate the jammed paper, the problem lies on the toner cartridge itself. When toner cartridge is not rolling over, it will stop feeding the paper and it will cause printer to jammed.

To diagnose the problem, put old printer cartridge and if no toner power, just shake it well and I am sure there is still small amount of powder inside it and if it prints, the toner cartridge you purchase is defective. Reason, factory defect or improper refilling and part is not working well.

I hope it is helpful and thank you for using FixYa !

Paper keeps shifting during loading and eventually gets jammed every time


Seems like the rollers are either dirty, or worn out. Probably the latter.

Stylus CX9400 Photo Printer: paper jammed inside printer...


If paper is jammed, a Paper jam message will appear on the control panel display.

Follow these steps to clear the jam:

  1. Gently pull any jammed paper out of the output tray or sheet feeder.

  2. If the paper is stuck inside, turn off the Epson Stylus CX.

  3. Open the scanner, remove the jammed paper and torn pieces, close the scanner, and turn the Epson Stylus CX back on.

    alert_note.gif Note: Be sure to check the far left of the carriage area when checking for jammed paper. Paper that is jammed there may be hidden from view.
If paper jams inside the Automatic Document Feeder, clear the jam as follows:

  1. Open the Automatic Document Feeder cover and remove any jammed paper.

  2. If necessary, lift the document cover and remove any paper that has jammed inside.

Paper jam went try to sent a fax


Step1
Turn the printer off and on to see if it can automatically clear some or all of the jam. Many printers provide an error-code listing on the front panel display for the area where the jam occurred. If your printer shows an error code, be sure and check the printer manual to see if that identifies the area of the printer where the jam occurred. 
Step
2
Turn off the printer. 
Step
3
Remove any paper trays. Inspect them for wrinkled or damaged paper. 
Step
4
Open any other doors that give access to the printer's paper path and to the toner or ink cartridge. 
Step
5
If necessary, remove the toner or ink cartridge. Place it in a bag or away from light to avoid damaging it. 
Step
6
If you find a piece of jammed paper, remove it by holding it with both hands and pulling firmly (see A). The goal is to keep the paper from tearing. If several pieces are jammed together, try pulling out the middle piece first to loosen the jam. 
Step
7
If the paper does tear, try rotating the roller gears manually to free the paper (see B). Don't force anything, though. 
Step
8
Replace the toner or ink cartridge and paper trays, close any doors you opened and turn the printer back on. 
Step
9
If the printer paper jam message still appears, then there is still some paper in the printer. Reinspect the paper path.

Paper Jam Error 2


Hello,
Don't try a dozen things suggested by people online who's credentials are unknown. Go straight to the source.

I had the same issue and just went to www.samsung.com - looked up my model #, downloaded the PDF manual 86 pages and did a search for that error. It had step by step picture diagram of how to clear out the jam.

I just saved the company a few hundred on a service call to our printer sales/service vender.

The sensor is stuck open or closed. It needs to move back and forth between the sensor. Check the paper path for the sensors.
