After a paper jam occurs in the rear cover of a Dell Laser Multi-Function Printer 1815N, the printer will not resume when the jammed paper is removed. This is the normal behavior of the printer as there is no sensor on the rear cover of this printer.

To open the back cover and remove any stuck paper, perform the following steps:

1. Open and close the front cover.
   The jammed paper may automatically exit the printer. If the paper does not exit, go to the next step.
2. Gently pull the paper out of the output tray.
3. If you cannot see the paper in the output tray or the paper does not move when pulled, open the rear cover.
4. Skip to step 9. If you do not see the paper, go to the next step.If you see the jammed paper, push the two blue pressure levers up and remove the paper.
   
5. Release the blue strap, the rear cover stopper, and fully open the rear cover.
6. Unfold the duplex guide fully.
7. While pushing the fuser lever to the right, open the fuser door. NOTICE: Make sure to unfold the duplex guide before opening the fuser door, or the fuser door may be damaged.
   
8. Pull the jammed paper out.
9. Return the levers, fuser door, rear cover stopper, and duplex guide to their original position.
10. Close the rear cover.
11. Open and close the front cover.
    Printing automatically resumes.

The paper jam could be in three places.
First:

Open the cover of fixing section, its above bypass, and check for jamed paper

Second:

Open the transfer cover, these cover has handle and it goes by pulling toward you, and check for jamed paper.

Third:

In hight of first paper cassette, on left sideway of copier, beaneath the bypass are small door, open it and check for paper jams. Be sure that you closed them properly because if they arent closed the check printer cover message will arrise.

Hope that helped

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.
   
   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.
   
   
   
   
3. Press OK to clear any messages on the display screen.

The tips for removing paper jam are basically universal for all laser printers so here is what I would do.

1) Open front cover remover toner cartridge, check for & remove paper. Reinsert toner and close front cover back up upon completion.

2) Pull paper tray / paper out and check for paper stuck in input paper area

3) On top backside of printer you should find a door that opens up to allow access to backside. Open this up and pull any paper out from within there.

There should not be any need to unscrew any screws and I would not recommend doing so to remove paper.

You should always be able to remove paper jam via openable doors.

I believe these steps should relieve the problem, if not please let me know & I will be glad to assist further.

Mine did the same once and although at first I was convinced it was the printer reading incorrectly, in the end, after opening all the parts that open up, I did find a sheet of paper wrapped around the rollers at the back.

Turn of the printer, and do not close any of the tray or doors before all of the jams are cleared.
1). remove the paper from paper tray, removed the tray and remove the jams.
2).open the front cover and removed the toner cartidge assembly, remove any jams in this area, and behid the toner cartridge asembly.
3).left the flap at the front of the printer adn remove any jams heneath the lap.
4).Open the rear exit and remove any james.
close all covers and reinsert the paper tray and turn on the printer.

Actually, you need to double check the back cover and front cover, open them all to check all paper jam.
Besure to check the back cover, normally all paper jam is from the back.
be sure to close the front cover at the last cover to close.
