HP 8500 unable to sense ink levels in two of three cartridges replaced. Tools panel shows yellow triangle with exclamation mark in it. Will return them all.

Beware of the power issue on HP 8600.  I have had it close to 2 years using it occasionally and then the power light starting blinking with a weak light.  I could not print from any device.  I turned it off and then on and it worked but after a few minutes the power would fade off.  The only way I can print is to turn it off and wait a few minutes to turn it on.  I am happy with the quality of the print but the power issues are very disappointing,  I changed all my ink a few weeks back so I hope it works long enough to use the $80 worth of HP XL ink.  The HP help site was not very useful and others had a similar problems.  As i was typing this the power went off the printer again.

HP 95 is not compatible with printer.  Will not accept the cartridge. printer message reads installed incorrectly, and that is not the case.

In spite of the advertisement and instructions for this product, I could not get my HP 8500 printer to accept the cartridges
A waste of money!.

It looks like my whole batch of 951s and the 950 XL that I ordered December 24, 2017 is incompatible.  I notice these are Malaysian made, labeled z10 for use in USA and Canada but they are rejected by my 8630 printer.  The previous China-made ones worked.

How do I get replacements for these that work on my USA-purchased printer?

My HP 8600 did not recognized them. I kept getting a mssg saying cartridges were not inserted and cartridge carriage would not move fully back in place.

I am currently using these ink cartridges in my HP Photosmart C4580. The ink works just fine, but the cartridge doesn't always register with my printer. This results in the common "low ink" message you get with a lot of refurbished/refilled cartridges, which is not really a problem. What's annoying is that I have to reseat the cartridges to get the printer to accept them. I think this is just when I turn the printer all the way off, so maybe I can remedy the problem by never unplugging it. However, twice now I have had to spend extra time fussing with these cartridges just to get a page to print.

Ruined by Epson XP-850 printer.  After initially working, they started printing only one color at a time.  After Epson had me had me clean the nozzles 4 times, now the printer says it does not recognize the C, M, and Y cartridges!  Absolutely terrible!

My printer does not recognize the new printer cartridges.  I am unable to print using referbished cartridges in my Dell computer

I have had nothing but problems with these and the J6520DW.  Can't recognize them and when it does it shows the ink being low.

I had the same results as others suggesting counterfeit ink.  Worked fine for awhile and then stopped as printer could not recognize cartridges.  I gave Epson support a hard time but finally bit the bullet and bought three color cartridges from Office Max and voila, problem solved.  Fortunately before I bought a new printer.

I am a prospective buyer of a HP 7660 printer and after reading the reviews, I noticed that
most them were favorable, however I was concerned about the comments of Dr. Tug, who was disturbed that when he used a refilled cartridge, that he kept getting a warning of a
low ink level whenever he went to print a document. I checked this out with P.S. Ink of Northfield, NJ, who I have used for refills on my present (now defunct) printer and was told that there are work around solutions to the problem. Altho I do not have the complete details, one involves rotating 3 different cartridges.

Worked great, printer recognized as non-hp but showed correct ink levels.

I recently wrote a bad review for this, I want to apologize.  It was the settings on my printer that was the problem, not the ink.  I just wanted to set the record straight.
Thanks!

Used it maybe 5 times to print out less than 20 pages and printer will not print due to low ink.
