Question about Epson ACULASER CX11NF All-In-One Printer

2 Answers

Worn K Dev Unit - can I get service for the CX11NF in the Greater Vancouver BC area?

Printer is out of warranty, and a call to Epson revealed that apparently the nearest Epson service centre to Vancouver BC for the CX11NF is in Québec?!?!?! I assked if they could give me any other contacts, even one in the States, but to no avail. So far there are no print quality issues, but we can't be without the printer so I'd love to solve this before it DOES become a big problem.

Please, can anybody point me in the direction of someone who can service this printer, or shed some light on what the message "Worn K Dev Unit" means? Google seems to be failing me here. I did read a thread regarding the C1100N, but am unsure if that model is similar enough that I can apply that advice.

Thank-you in advance for any help at all!

    How do I reset the dev unit. Epson has supplied one to me. But refuse to give me the reset procedure.

    Thanks for all your help. Turns out we did nothing wrong the reset we initially used was the correct one. The client dug out a two year warranty. We called Epson for them and arranged a warranty agent to go out to them. The problem was deeper. I believe in the end Epson replaced the whole developer assembly.

    Thanks Inky
    If the problem was that easy I wouldnt have asked for help. I have been doing this for 15 years. Already fitted dev unit and reset the machine through the user reset. The machine reset, but as soon as the customer turned the MFC off and on the worn dev unit sign came back. Thanks for the manual link, all I need though is how to get into the tech service mode to see if I can reset the machine from there.

    Kind regards Imagetech

If Epson have provided you with a new Dev unit ( black plastic thing with a roller and black powder in it), get a service manual so you can install it. It is VERY straight forward and if you can use a screw driver and have opposable thumbs, you should be able to do it about 20 minutes.

Try this place for a manual

I understand that Quebec may far from where you're located at having a service manual is practical but risky. It may do damage than make better. What I'm try to say is you choose to use the service manual or send it for service. Nothing can replace the hand of an expert and experience in handling such a valuable piece.

I need a serial number from someone's CX11NF printer.

Not sure about Epson but some brands chip their supplies so they only work in one country or geographical region. This is done because the pricing is often quite different based on the ecomony and competition in the area. Are you sure the unit is DOA or is it just not being recognized?

People think about it. Contact the manufacturer of your specific model for the error codes or order an manual from them. Most people seem to soft to actually do the research. If a company has fallen from grace I can see the extra outreach but look it up. I can.

Epson CX11NF-Vertical line on output of adf... Vertical line appears only on output of adf scanned docs on Epson CX11NF printer.

There may be dust or dirt on the small glass strip. Lift the scanner unit so you can see the scanner glass. To the left you will see a small glass strip. That is the area that you will need to clean. Make sure it is spotless as any stuck on dirt will cause the problem you are having.

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.

The answer to you question is "no". Epson printers do not have developer units mixed in with the toner. They are a seperate unit all together. If you look around, you might find an epson warranty service agent who is happy to sell you the developer, however dependant on the unit, they are fitted in variouse ways and may require some technicle expertise to install.

Try going to, epson's distributor. check if there is an exploded diagram for the unit. Then go to look for for the model under printers then click on manuals. I can't guarantee you will get the service manual but you will find lots of info for the printer.

Hope this helps.

No function on my printer is working

E-511 error message is related to the Photoconductor Unit. In order to resolve your issue, there 3 things that I'd like to suggest.

1. Take out the Photoconductor Unit and turn it upside down check if the white tabs restract. If it doesn't you need to replace the PCU otherwise just put it back in

2. If reseating the PCU doesn't resolve your issue, try a different PCU

3. Lastly, warranty options if your product is within the 1-year warranty from the date it was purchase contact Epson Tech support they'll be more than happy to send an onsite tech support to fix it otherwise visit their website and look for a repair center in your area
