After I cleared the paper the printer still keeps "detecting" the paper jam.
Have tried unplugging power and shaking and they didn't work.
I saw the post about exiting paper sensor:
But E525W's structure is different so I cannot find the counterpart.
I also read about the diagnostic mode of other models but there's no information about how to run diagnose on E525W in user manual or the knowledge base. I don't understand why Dell doesn't provide these.
Anyone knows how to solve the problem? Thanks a lot!
To Dell workers: please save you time from pasting the standard "how to remove paper" guide in the reply.
Solved! Go to Solution.
For that error its the registration sensor that has been obstructed for the timeout length tripping this error code.
The regi sensor is at the back door side of the bottom of the printer so to get a clear view of it you have to remove the paper tray also and look from both the rear door of the printer and the bottom of the printer. This is easiest to do if you tip the printer on its side. You are looking for a small black bar which is beside a white plastic bar attached to a spring.
If the paper tore as you removed it to clear the jam there could be small pieces remaining at the regi sensor bar that can trigger this sensor to thinking there is a whole sheet there.
If you can see the small black lever that actuates the sensor and it is moving freely and you are still getting the error then it can be a problem with the sensor itself.
If the sensor is moving freely and you are still getting the code then I would try cleaning all near the base of the lever with compressed air as a very small peice of paper stuck in the sensor can cause this. If it still is not working after that then its most likely a problem with the registration assembly, the wiring harness or the MCU which you would have to replace the printer for.
077-900 code. There never was a paper jam. Just quit in middle of a print job and got paper jam error. Have tried everything suggested on this forum. I use quality high-white 24# paper so the printer is quite clean inside and low page count. I am retired now and this printer has an easy job with home printing.
Dell already replaced this printer under warranty. The 'refurbished' replacement came with the small output tray extension completely missing, the toner door won't stay shut (I have to tape it shut).
I love Dell computers; have had dozens over the years. I currently have three. But the printers are junk. Is there a solution to this poor service, poor replacement on warranty (it should have been a new one, not a half put together second hand printer).
