6400 'out of paper' but paper IS in tray

"Paper Jam" issues are common with printers. They most often occur right after there has been a paper jam. Most people (not necessarily YOU), don't take the time to read how to properly clear a paper jam in their printers and often yank the jammed sheets backward thru the paper tray. Most times you should remove the cover in the back and pull the jam FORWARD out the rear, or if the jam made it close to the output tray, then FORWARD thru to the output tray. Pull sheets backward can cause two issues. It makes tearing the paper easier. This can result in tiny pieces being caught in places where the printer detect them as a jam. The other issue is that pulling backward can damage the feed rollers that pull the paper into the machine, as well as the mechanical sensors that detect paper jams. If you cannot find ANY shards of paper in the machine, you may have printer damage that results in the jam indication.

You have a pick up roller that needs replaced. If you pull the tray out, take a flashlight and look up into the printer. You will see a black roller. It probably is covered with white paper dust and slick looking. This needs replaced. That is all that is wrong.

Your best method of troubleshooting is the manual sensor test as this is a generic paper jam error.

on your sensor tests:

0 = off
1 = on

A = TOP OF PAGE SENSOR
B = PAPER LOOP SENSOR
C = N/A
D = FUSER PAPER SENSOR
E = DELIVERY-TRAY PAPER-FULL SENSOR
F = FUSER PRESSURE-RELEASE SENSOR
G = MEDIA SENSOR
H = N/A
I = MP TRAY SENSOR
J = CASSETTE SENSOR
K = DOOR OPEN DETECTION SWITCH
L = DEVELOPING ESTRANGEMENT SENSOR - CLR
M = DEVELOPING ESTRANGEMENT SENSOR - BLK
N = MP TRAY MEDIA POSITION SENSOR


A-F are paper path sensors - you can toggle them and watch if they change from 0 to 1. If they do, the problem is not in that area.

G can have states from 0-7 each one representing a different type of paper - shouldn't have anything to do with jamming.

hope this helps. probably a tiny piece of paper or toner somewhere. could also be a torsion spring out of position on a flag.

Hi,

The problem is that the printer thinks that there is a paper jam inside the printer. What could be happening is that there was a paper jam the paper was pulled out but the actual sensor that detected the paper probably got damaged, either broken or malfunctioning. In this case try the following, turn off the printer and open the front cover. Then press and hold down the two front buttons while having the cover open and turn the printer on. Then wait untill the bottom light stays on solid then release the buttons that should reset the printer. If after that the paper jam error does not go away then you are probably looking at a damaged sensor. To fix that you will have to take it in to have it service.
Hope it helps.

Hi there,

Here is the most important thing to understand about paper jams in any printer....

The printer does not know if there is a paper jam anywhere in the printer.

What it does do, is respond to sensors ( optical sensors, either open or closed, by plastic flags). These flags are moved as paper moves through the paper path.

One example of a paper jam message when there is really no paper jam, is when the feed rollers are worn and do not pick up paper from the paper tray.

When you start printing, the printer expects that first sensor to open ( paper passes the sensor ) at a very specific point in time. If the paper did not get picked up from the tray, then the printer will ASSUME that the paper must be jammed somewhere because it did not reach it on time.

Now this will also happen if in fact the paper did get picked up and then jams prior to the sensor.

So... if you get the picture of how this works, understand then too, that if the printer is showing a paper jam message at power on, then one of the flags is open when it should be closed.

If you do not actually have a piece of paper holding this flag in the open position, then the flag is possible broken.

I usually see this kind of damage occur after a true paper jam, where the paper is removed either in the wrong direction ( pulled out back the way it was going instead of the way it should normally travel ), and this breaks the flag, or it was pulled out forcefully again, catching on and damaging the flag.

All of the above pertains to ANY printer, and not just yours. you must take care to fully inspect every inch of the paper path, from the paper tray, to the exit, use a flashlight, and look for the sensors and make sure they are not blocked or broken.

Good luck,

Cory

try this, its probably a small part of jammed paper or then theres a problem with the pickup, try cleaning it.

1. Turn off the printer.
2. Remove any paper trays. Inspect them for wrinkled or damaged paper.
3. Also open the back cover of the printer if this model has one.
4. Open any other doors that give access to the printer's paper path and to the toner or ink cartridge.
5. If necessary, remove the toner or ink cartridge. Place it away from light/ sun light to avoid damaging it.
6. If you find a piece of jammed paper, remove it by holding it with both hands and pulling firmly. 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.
7. If the paper does tear, try rotating the roller gears manually to free the paper. Don't force anything, though. Do this step especially if the jam message comes up repeatedly without any obvious paper jam, there may be a small tear of paper inside.
8. Ones the printer is free of paper Replace the toner or ink cartridge and paper trays, close any doors you opened and turn the printer back on.
9. If the printer paper jam message still appears, then there is still some paper in the printer. Reinspect the paper path.
10. see alternative if the problem is still not solved.
    

alternative :
Load a piece of thick paper, for example photo paper and press the resume button (may be diffrent button on diffrent models) a few times to the printer picks up the paper and puts it through the machine.

Remove the tray and check the wire you mentioned, that it is connected to the paper end sensor.
Probably the paper end sensor has its plastic legs broken.
If so, replace the paper end sensor and you will solve the error message.

Good luck and please rate me, thanks.

Hi,

To clear a paper jam:

• Pull Carefully
  If the sheet of paper is visible at the output slot of the printer (in other word, it stopped on its way out of the printer), try pulling carefully on it. If it pulls smoothly and easily, then carefully pull it the rest of the way out. If there is resistance, then stop and go on to the next step.
• Open the Cover
  Open the printer cover and wait (in the case of an inkjet printer) for the carriage to stop moving. Carefully, slowly pull out any paper that is caught there.
• Take Care
  Do NOT pull paper out from where it was feeding into the printer (where the blank paper enters the device). The rollers on your printer may only go in one direction, and if you force them the wrong way, you could damage the machine.

Be careful of the following:

• Laser Printers
  If you have a laser printer, be very careful when pulling out the paper -- laser printers can get hot.
• Paper Shreds
  If any paper tore, either during the jam or while you were removing them, remove any appliances that you can (paper trays, etc.) and look for the shreds of paper. Try to make sure nothing has been left behind.

If you have frequent paper jams:

• Don't Overload
  Overloading your paper tray can cause paper jams. Your manual may say that your input tray can hold 250 sheets -- but if you keep getting jams, try loading 225 sheets instead.
• Check the Paper
  Check the minimum/maximum paper weights that your printer can handle. Paper that is too thick, or too thin, can cause jams.

Goodluck..
