Where are the paper path sensors?

It could be a damaged or defective jam sensor but more likely a tiny scrap of paper stuck in an inaccessible part of the paper path. You may have to open up as much of the paper path as possible and shine a bright light inside to locate the culprit.

There are lots of reasons for paper jam...
... Take a look where it always happen.. There might some paper stuck on its path why its always Jam.. or the sensors are blind... get a paper.. roll it and blow it on the sensors... and sometimes broken parts..

hi did u have cheq all the paper path sensors may be any one of them stucked or may be if you have old machine may you have clean whole paper path sensors thanks

Usually when you see this the problem is just the paper or the tray isn't quite inserted correctly. There is a paper sensor arm that expects the paper in a certain position and place. It's not a real smart sensor so all it will say is no paper. You want to makre sure the feeder tray is inserted properlly. If you have used it a lot it may have some wear or movement and this will be enough to give the error. So check that it is seated properlly (straignt and secure). For the paper you want to make sure it is inserted to the stop. You don;t want to force it in but make sure it is in far enough.

Those might seem rather obvious but about 99.9% of the time that is the problem and just taking the paper out and putting it back in very carefully, clears the error. Having said that there is of course a chance that the paper sensor has failed. This is where it can get tricky. The sensor is fairly easily replaced but if you can't do that yourself you should consider that the cost of labor and the part will add up to a bit of money. This is covered under warrenty so make sure you check if you still are covered by factory or a store warrenty.

is a small finger plastic, stucked on the paper path, release-it and problem solved. (Is very fragile, so use a small tool to release)

there a small plastic sensors on paper path, normaly you have some sensor stucked.

you can check all paper path inside printer, there is a paper door nearby power input. open-it and locate the sensors small plastic finger check for free mooving operation.
normaly is one of three sensors (one for no-paper, 2nd for middle of paper path and one for paper position nearby print-head, test path with a paper, for free path.

You probably have a small piece of torn paper jammed right up against the paper jam sensor. You'll need to open it up and check the entire paper path for it. Even a small piece of paper can trip the sensor if it's in the right place. If you can't get at the entire paper path, you may need to take the printer to a qualified computer repair shop and have it done. Most shops won't charge you a lot for this job, and it can usually be done while you wait.

prior to the issue ,basically is your paper path sensor .1)firstly try to check all the sensor lever ,it must be at home position .i guess one of the paper path sensor lever activated paper present.this usually happen when removing jam paper incorrectly causes the lever sensor spring came off .2)it can also be the clutch and solonoid rotation timing issue.good luck ,pls rate me if u satisfy wih my clarification.!!!!!!!

1: Remove Cartridge
2: Unplug the AC Power Cord
3: Hold down the RESUME button
4: Release RESUME after plugging in the AC Power cord.
5: Press the RESUME once within 5 seconds and release the RESUME .
6: Press and HOLD RESUME for two seconds or more and release it.
7: Press and HOLD RESUME for two seconds or more and release it.
8: Unplug AC Power Cord to set data.
Try this I found it doing a search on your machine, that foam was called a blotter, and it should work without it, good luck

please check if all paper sensor arms are present and not blocked.
Sometimes on of then will be missing or broken.
The center sensor just below the separation pad is the paper end sensor. If this sensor don't work, the scanner do not stop feeding.
It means you scan on sheet, the scanner eject it and then the feed motor do not stop because the paper end sensor don't record a paper end.
Another case may be a driver error. In case you are using XP and installed a new service pack please check your SCSI driver versions (ASPI32 and so on) and TWAIN resp. ISIS driver and update them.
