Error "Service req E521"

Hello, I'd like to know if anyone has seen this particular error or knows the meaning of it on the CX11NF. I am unable to clear the error. I beleive it may be an engine type error based on the noise at startup.

    Thanks for your help INKY. I've tried that website but didn't see the manual for CX11nf there. I'll have to look around for it. Thanks again.

Same issue here ! Had the printer 15 months. Printed out a 60 pages color doc with a lot of blue in it and dust went all over the inside Have tried cleaning up but it now works a few times then stops. Tech support is worthless! It keeps also asking for a new black TOner - I tried it but stills happens

Epson Acculaser CX11NF Error 'Service Req E527'

Hi.. To fix the E527 error, close the front panel (cover A) and open the top cover (cover B). With the photoconductor unit removed, the toner carousel will rotate. It only rotates if cover A is closed all the way. You can easily rotate the carousel to a position where you can remove/reinstall the toner cartridge if stuck.

ADF Jam... Service req c2011


Can be a tough one.

1st - Open the ADF & make sure that the 2 little Sensor tabs move freely.

2nd - Lift the ADF & check that the White Plastic Paper Guide is "down in the slot" & not resting on edge of the white flat bed scan pad or overlapping the scan pad.

For some C Error Codes

Check for electrical interference from external devices.
Disconnect the Printer from all devices, and run a test print..

Here are the "c2011 error" fixes per the manufacturer:

Replace the Automatic Document Feeder.
Replace the Scanner.
Replace the Main Board.
You might try unplugging the ADF & see if you can operate without it.

If you unplug the scanner, the printer might not function.


Service Req C0302

CPU Error. Mainboard is faulty.

Service req E527 error thank you it helped - the cartridges are still difficult to manouver - do you know if the plastic strips (with sticky tape) are meant to be there or not?

I imagine not. Usually, those sticky plastic strips are there for shipping purposes. Where exactly are the strips? Knowing that will help me advise you further.
