C9345 Maintenance Box Compatible for ET-5800 ET-5850 ET-5880 ET-8500 ET-8550 ET-16600 Pro WF-7310 WF-7820 WF-7840 EC-C7000 WF-7830 ST-C8090 ST-C8000 Printer

I received this product a day early which was a super pleasant surprise. I just purchased the epson 16650 and haven't had great luck with clean nozzle checks thus why the maintenance tank needed to be replaced so soon. Epson has been out of stock which basically left my $1200 printer useless. I was a bit skeptical since this seller didn't have any ratings or reviews. I know how hard it is in the sales business especially when no reviews are shown so I wanted to be the first to state this product did exactly what it was supposed to do and now my once useless printer has now been given life again no thanks to Epson lol. Will def order again.

I thought there might be an issue, but removed the Epsom box, installed this replacement, and printing like new. I was unable to print for 2 days so it's nice to buy a 2 pack.

Although I was a little irritated that a "non- Epson" version was priced higher than the actual Epson brand, I must say that it was at least available to purchase for immediate delivery and I can now print again. Like others, I was nervous to buy an off-brand, but pleased that everything is printing correctly and I have not had any issues since installing.

Update 1/2 hour after reviewing. Out of curiosity, I checked the service level on my maintenance box, and it appears to indicate 75% full, after 1 week. So I anticipate, this box will soon fail. I'll contact vendor to see if there is a way to reset. Otherwise, I advise DO NOT BUY THIS.It works. That's the bottom line. I love the Epson 5850 Eco-Tank printer. Ink lasts a LONG time and the replacement bottles of ink are reasonably priced. What I don't like is this maintenance box design. Once mine filled up, I took it out, opened it carefully, disposed of the filled ink sponges, cleaned it and cut new sponges to fit. I put it back in and my printer was working well for about 2 months, until the chip ratted me out, reporting end of life. It's good that it tells you it's full, avoiding an ink waterfall, but it's easy enough to clean and add replacements sponges. Anyway, this after market replacement works, and I was able to clean my print heads and get back to work. I'll update if it doesn't last as long as the original (about 2 years)

A+ Seller A+ Product

Looks like the original and fits perfectly. Printer shows box reset so good to go for awhile

I ordered 2 of these because my original box was full and wanted a spare. I loaded the replacement into my WF-7840 and the status indicated the box was still full. I contacted Epson directly and they determined this was a 3rd party product and cannot determine its effectiveness. Is it working? No clue.

Installed in 5850.
