Question about Xerox Phaser 8400 Laser Printer

1 Answer

Paper Jam detected. None found.

My Phaser 8400 seems to detect a paper jam. The message is "Paper Jam - Open front cover to clear." I have opened everything on this machine that appears to be accessible, removed the paper tray and checked all the visible areas of the paper path and cannot find any paper. I'm thinking that a sensor may be causing the problem but, if so, I'm not sure how to resolve it.

Here is the Xerox support page for your printer. It even has a movie on removing paper jams.

Hello, I always rcv a message that said that there is a "jam paper problem", but really there is not paper jam in the printer. I did all the solution that I read in the instruccions, but the same...


This seems to be fault in the transport of the paper in the rollers. So if you have used any adhesive sticker printing, it is possible that some glue has got clogged into the rollers. If not there can be some jammed paper in the rollers or the mechanism.
So start this work only if you are mechanically able with the right tools.
Remove the covers to get access to the mechanism . Remove the motor drive assembly , the fitting of the motor to the mechanism. Once this is removed the rollers can be turned manually so that you will be able to feed a paper to see the progress of the movement while studying if there is any obstruction or damage to the paper.
There is a in-detect sensor, usually an opto-coupler , make sure this is not clogged or dirty as this IR detection feeds the signal to the processor for starting the motor drive feed.
Reassemble but make sure the rollers are aligned to be in equal gap to feed the paper without a side pull. Now you must print and see if the fault has changed. If not repeat the above work to confirm the area of obstruction.

It said to open from cover and remove paper I did and It dont work


If you receive an "Open front cover" error message the solution is to open the cover and remove the paper and any remnants of the paper jam. If there is no obvious paper remnants jamming the printer and you continue to receive an error message I would suggest unplugging the printer from the power source.


After 5 - 10 minutes plug in to power source.


Turn on printer.


See if this has resolved error message. If not you will need to check more carefully for paper remnants that would be causing the printer to detect a jam.



Trust this is helpful. :)

I'm getting Jam at Reg Roll on my Phaser 6180, and I think there may be a bit of paper in the paper path, but i can't see it. The machine says Open Door A, which I've done a few times, but it isn't...


Had exactly the same problem... today actually.

Found the solution with another model's manual - I removed the paper from the top, but hadn't realised there was a jam in the paper tray. It was only when pulling it out completely that I found it as below...

Jam at Registration Roller

1. Remove Tray 2 completely.

2. Clear the jammed paper from the printer's

intake slot.

3. Re-insert Tray 2.

4. Open front door A.

5. Remove jammed paper if present.
6. Close front door A

Recurrung jam message


if there's no paper jammed then a sensor might be dirty, the printer has several sensor along the path of the paper to detect its flow.

Paper jam and still won't print


Hi

Thanks for using FixYa. Before you can clear the error message, you must locate where in the unit the paper is jammed.

Unplug the machine for safety. Now follow these instructions based on where the paper jam is located.

1. Pull the paper tray out of the machine.
2. Pull out the jammed paper.
3. Reset the machine by opening the Upper Jam Clear Cover and then closing it.

If you cannot remove the jammed paper from the front of the machine, or the error message still appears on the LCD after you have removed the jammed paper, please go to the next step.

4. Remove the Lower Jam Clear Cover from the back of the machine. Pull the jammed paper out of the machine.

5. Put the Lower Jam Clear Cover back on. Make sure the cover is set properly.

6. Open the Upper Jam Clear Cover. Make sure that there is no jammed paper left in the corners of the machine.
Note: If the paper is jammed under the print head, unplug the machine from the power source, then move the print head to take out the paper. 7. Close the Upper Jam Clear Cover.

8. Close the output paper tray cover and slide it forward, then push the paper tray firmly back into the machine. While holding the paper tray in place, pull out the paper support until it clicks and unfold the paper support flap.

Please do rate the solution and revert for further assistance.

Thanks

Phaser 8400 paper Jam


The preheat entry assembly has paper detectio arms/sensors that will get brittle and break off, leading the machine to think there is a paper jam. This problem usually will require a trained technician to diagnose & repair.
