MS.R C9345 PXMB9/C12C934591 Ink Maintenance Box Replacement for ET-8550 16600 5850 5800 16650 8500 5880 WF7840 WF7820 WF7310 ST-C8000 C8090 Printer(1 Pack)

After reading the reviews on a lot of these for the 8550 I was very nervous so I ended up ordering a maintenance box from Epsom itself, but it wouldn’t be here in time that I actually needed it so I ordered this one as a back up and thank the Lord it actually worked. if you have an ET 8550 and time crunch definitely get it. I’m still happy I have the original factory maintenance box on its way, but I’m very glad that this worked as well

Works great

Exactly what I expected.

Works as described, thanks!!

After installing it as per the instructions, the printer did not respond, Repeating the instructions again did not work, I do not recommend purchasing this product.

Not useful, waste of money.

This maintenance box replacement for my printer is working great!Installation was quick and easy and it works perfectly with my printer, keeping it running smoothly.The box efficiently collects excess ink, preventing any mess and ensuring my prints remain clean and high quality. It’s a reliable and essential part of printer maintenance, helping to extend the life of my machine.The replacement process was hassle free and I’m thoroughly impressed with its performance.

Don't let the plane appearance fool you. These things work great and they go in and snap into place just like the original cartridges. There's been no problem with these whatsoever that I can see.This is a printer that we use daily even if we don't necessarily print a whole bunch. So these are going to last as a good long while is what it seems like because at about a month later it's still going strong.These appear to be a pretty good value to longevity ratio in my opinion
