Persistent paper jam message

Most larger printers now-a-days have compartments that open to give access to the internals of the printer. Open up these doors and see if you can see any pieces of paper stuck in the feed path.

13.10.00 jam inside lower left door or 13.10.00 jam inside duplexer Description A media jam has occurred in the duplexer area of the printer. Action

Hope this helps.

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. Step 2 Turn off the printer.
   
3. Step 3 Remove any paper trays. Inspect them for wrinkled or damaged paper.
   
4. Step 4 Open any other doors that give access to the printer's paper path and to the toner or ink cartridge.
   
5. Step 5 If necessary, remove the toner or ink cartridge. Place it in a bag or away from light to avoid damaging it.
   
6. 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.
   
7. Step 7 If the paper does tear, try rotating the roller gears manually to free the paper (see B). Don't force anything, though.
   
8. Step 8 Replace the toner or ink cartridge and paper trays, close any doors you opened and turn the printer back on.
   
9. Step 9 If the printer paper jam message still appears, then there is still some paper in the printer. Reinspect the paper path.
   

try realigning the paper into your printer. the paper may not be able to to feed directly into the printer.

1. try reinstalling the driver
2. reboot the printer.
3. try to feed the paper into the printer by looking for the feed button on your printer. or you can enter the printer settings and look for the maintenance task components.

pm me if you still experience problems. I will give you another options. Thank you. :)

Acording your explained you need do
1) clean the input tray roller surface, to make sure it has enough grip force.
2) looking for a sensor around the roller rear, it could be cause the paper jam there, because if the sensor does not detect any input paper go throug there then should be stoped at roller rear.
3) if you find a optical sensor there, please use a slft cotton stick to clean its surface. (maybe open some cover needed)
hope you fix it , ask me any time please!

Buy a new one!!

In response to a question by Fixya. I solved it by searching throgh all references to paper jams on Fixya. I found a solution which I have already described. This is a very helpful site.

I have a similar but different model B4300. Several others, & I have found that a small piece of paper 1/2 square may lodge under a plastic guide, holding open a switch. This is very difficult to notice if you don't know where to look.
Open top lid
Remove the ink cartridge/roller drum as a single unit.
Look in the printer at the metal roller in front.
A Plastic strip on top & in front of the roller covers 2 square holes which should look dark. On your LEFT, as you face the unit, there is a small magnetic switch, to the LEFT of the LEFT square hole, under the plastic.
In my case, the paper was seen as white in the hole, and extended under the switch. I was able to grasp it with a small medical forceps, next to the switch. By gently twisting, I pulled it out without taking the unit apart.
The printer then worked perfectly after the paper under the switch was removed.

If your oki is like the 4300 we use it may be as simple as making sure the extention for the back tray (where the paper is printing to now) is pushed all the way in. This actually selects the tray option. If this tray extention is pulled out at all, your printer will print to the back tray.
