How do I get my Epson XP-635 to accept compatible ink

Customer Question

How do I get my Epson XP-635 to accept compatible ink cartridges?

Hi, I'm Nathan.
Sorry to hear that you're having trouble with this but I'll do my best to help you.

What cartridges are you using? Are all of them being rejected?

Customer: replied 1 year ago.
The cartridges have come from several different suppliers and all of them bar one black cartridge have been rejected.
Expert:  Nathan replied 1 year ago.

That is, unfortunately, quite common.

This isn't so much a matter of the printer as it is the cartridges. Those generic cartridges, though listed as compatible, have poor quality control and very high failure rates. On average they work only about 60% of the time right out of the box. You may have just had a bad batch, though some are better than others.

If the printer will accept some, or will accept the genuine epson ones, then it is not a printer issue, it is a matter of faulty cartridges/chips on the generics.

Have you tested or successfully used the proper oem cartridges recently?

Customer: replied 1 year ago.
they all worked. In the past with my other Epsons, the only printers I have used, the failure rate was very low. With the XP-635 it just refuses to recognise them.

This is a newer model than some of your printers likely, and that may have something to do with it as well, they purposely try to deny the use of other cartridges if they aren't an exact fit. The "faked" cartridges won't work in most cases, if it is a cartridge that was an original epson one that was just refilled, or a new cart with an oem chip in it, that is a different story though.

I still believe this to be just bad cartridges, and eventually you'll likely find a brand/model that will work.

Just to be safe though,

What we can try are some cleaning and reset steps.

First remove all of the ink cartridges, then clean the metal electrical contacts on the back, as well as where they mate up inside the printer, using qtips and rubbing alcohol. Dry well, then reseat the cartridges.

Then reset the machine:
unplug power at the wall outlet
wait 5 minutes
press and hold the power/on button for 60+ seconds
keep holding while plugging back in, and for another 60 seconds after, then release

Let me know the results, and I'll advise further if needed.

Nothing changed except that I now have a message to replace an ink cartridge.

The only one I have is a "compatible" cartridge.
Expert:  Nathan replied 1 year ago.

Thanks for trying,

unfortunately at this point, there is nothing more that can be done to force the printer to work, the remaining options are to replace the printer with a different model that more readily accept those cartridges, switch to a new model printer that utilizes a CISS system with separate tanks, replace with genuine epson cartridges, or keep experimenting with another brand of generics until you find one that is accepted. I'd be happy to recommend some other printer models that would work better for you, if you'd like to go that route.

Best regards, ***** ***** for the news,

Thanks for your effort. I have my eye on another printer that charges so much a month for ink and it sounds a good buy.
Expert:  Nathan replied 1 year ago.

That could be an option as well, if you print in sufficient volume for it to work for you financially.

If you wish to have a better quality and longer lasting printer, that comes with years worth of ink up front, consider the Epson ecotank models instead:

Alternately, for a more business/commercial grade product that will be rated for a 5 year life, consider a laser printer. Lasers cost more up front also, but a toner cartridge can last for thousands of pages. A black only all in one laser is around $125:

while a color model is about twice that:

If you have any other questions, just let me know. Otherwise, please take a moment to rate my service using the stars at the top of the page; hopefully I have earned 5 Stars. I also invite you to contact me directly with any future support needs at and ask for Nathan.

Thank you, ***** ***** a nice day,
