I Have an hp photosmart d110a and had the cartridge refilled at costco. The printer will not work saying theta the cartridge has a problem.What can I do to get it to work?

If it is a new genuine up cartridge and not out of date contact hp and they will replace it. If it is an aftermarket unit it will always say that and may not work. There are good aftermarket brand and not so good.

hp notify I am hp tech engineer , you should not use refill ink

The HP cartridges have a chip on them, you must reset it after recharge using a special gizmo, otherwise the cartridge will be considered defective by the printer and rejected. Go back at Costco and ask them to reset it.

These types of severe cartridge errors (i.e. "refer to documentation" / "incompatible cartridges", etc.) typically indicate the internal micro-electronics of the HP #60-61 cartridge are electrically damaged. The cartridge's electrical wire runs at rear and lower side of the ink cartridge, are very delicate and are somewhat susceptible to ink attack over time, which can lead to premature failures. In addition, the older the cartridge the higher the chance of an internal electrical failure due to prolonged ink exposure and subsequent circuit corrosion. I suggest you always run a 'Tap 41' diagnostic test to check cartridges electrical health (this is a forced test); you may also bypass the error (temporarily) on C4600-C4700 models which use HP 60 cartridges.

your cartridge have not been refillied in the right way
you must replace the chips with new ones

What is a incompatible print cartridge? The printer "Thinks" that the print cartridge, is NOT an original HP PhotoSmart one. Even print cartridge have chips.

> won't accept

Error-messages? What happens? What does not happen?

Did you refill the ink-cartridges yourself, or did you take it to a company that does the refilling?

If you mean the HP DeskJet F380 cartridges (the HP 21 and HP 22 cartridges) you will have unreliable success refilling these cartridges either yourself or online, at Costco, Office Max, and Walgreens. These refillers generally don't have fantastic quality control or knowledge of printer cartridges. I suggest Cartridge World or Office Depot refills. If you mean the HP Photosmart C8180 (the HP 02 cartridges) refilling them is easy but you need to replace the chip on the cartridge for it to work in your printer. As long as a refilled cartridge has a new chip it should work in your machine. Again I recommend Cartridge World or Office Depot refills.

remove the top cover of cartridge and just use your common scence you will refill it
