We have a code JOO..can't find paper lodged in it...I can open side panels but can't see how to take anything out to find a piece of paper..

that happened to me once and upon close inspection I found a staple lodged in it...check for anything lodged inside

The flashing error code that indicates a jammed printer is the digital-age equivalent of a flat tire. Sooner or later it happens to everyone, so you'd better know how to get things moving again if you want to finish your print job.

1.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.

2.Turn off the printer.

3.Remove any paper trays. Inspect them for wrinkled or damaged paper.

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 in a bag or away from 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 (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.

7.If the paper does tear, try rotating the roller gears manually to free the paper (see B). Don't force anything, though.

8.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.

HI,I had the same problem today. I ended up taking a piece of paper and from the back side started lightly forcing the paper in the back slot. I had the top cover open where you replace the ink cartridges. Towards the back you can see the paper start coming into the printer next to some rollers. On mine there was a small black switch about an inch from the right in the middle of the plastic piece above the rollers. Once I started pushing this paper in I could see this switch was stuck in the down position. After several minutes of pushing the paper in and out the switch moved up and out of the paper path. I then pulled out the paper and hit the ok button and it came on line. This may work better with a piece of card stock.
That switch is the issue. I ended up finding an object lodged against the switch. Needed a flashlight, plastic giftcard and a tweezers to get it out. Works great now.

Also,open the printer where the paper for printing is put in.
At the back left hand side there is a white long piece and either side a white piece with a small square on it.
Use a longingish screwdriver and push this gently down. It will click back into place quite easily.
Note: this tops the paper from feeding in and needs reseting after a jam.You will know all is OK when a sheet of ordinary paper is put in > touches the feed roller above the white bits, and is level across the paper feed area.

Hope it helps,,

Thanks for using fixya.....

Isn't that a paper jam? If so you may have a piece of paper somewhere lodged in your printer, Check all moving parts to see if you see anything.
Laser printers are more sensitive than Bubble Jet.

I had a paper feed problem with a Canon MP 250 and solved it this way. (not my own)

After many attempts t clean the feed rollers etc. I tried the following.

I cut a piece of card stock about two inches wide. I fed this sock from the front to rear and carefully worked the card stock in and out and from side to side (flossed it) and dislodged a drywall screw !!

I realize that having a drywall screw lodged in the paper feed is not common, however this "flossing trick may help to clear the paper feed path in other situations.

take out drum unit, look at the bottom side of it. there is a slot opening in the middle. it may have a small piece of paper lodged in that slot, preventing your sensor lever thats under the drum, from working.

hth,
razors

i had this problem, i was convinced that there was no paper stuck in it, and in my frustration i ended up tilting it backwards and banging it on the table. i found a pen was lodged in the paper feeder. I was so relieved, until the error code was still flashing. then i stuck my hand down the paper feeder (take the paper out first) and found the smallest piece of paper stuck in it. try this.

i am so relieved.

on the back side thers are two papers sensors inside the printer,they get stucked,normally they should come back

Paper Jam. Inspect paper path,maybe there is some piece of paper on the sensor actuator.Switch off machine,wait 10 seconds and switch on.Also check all doors,covers are properly inserted/closed

Have you checked the paper path for anything which might be lodged there? A small crumpled piece of paper, paper clip, or even some broken piece of plastic from inside the printer itself. Are the rubber rollers extremely dirty/covered with paper dust? Depending on the design of the printer, one set of rollers may be spring loaded, and if the spring is broken, disconnected etc, the tension on the roller of course goes away. Anything like this will prevent proper paper movement through the printer
