Replacement cartriges(Office Max) HP7350.

There is no resettable page count on this printer. If you are referring to the counter for the toner level, that is reset by a chip on the cartridge. That chip only works once and if you are using a refilled cartrige that chip should have been replaced. If you refilled it yourself you will need to check on Ebay to find a replacement chip. If you bought a refilled from someone else, take it back and get them to change it. If you bought an OEM HP cartridge and it does not reset the count then call HP as the guarantee their cartridges.

did you replace orginal HP cartridge? if you are change refill or any other kind of manufature cartridge , there is chip is not working properly, that's why ligh is blinking, use orginal HP toner or good quality brand

The HP 940 cartridge is the new version of the HP 88 cartridge. Both have a chip that estimates ink levels. Once the chip says the cartridge is empty it will refuse to print, no matter how much ink is really left in the cartridge. This is a safety measure so you don't get air in your ink lines. If you get air in an ink line, that color will no longer print. We can refill the HP 88 because there are replacement chips available for these cartridges. I own a Cartridge World ink refilling store and I don't refill the HP 940s yet because I don't have access to a replacement chip. If you purchased a refilled HP 940 and it's not working, I would say the chip has not been replaced. I would wait until a reputable refiller (i.e.-Cartridge World, Office Depot, etc..) offers refills for this cartridge before you try anything off the internet.

Those cartridges have a chip on the bottom front, that chip needs to be reset or replaced when you refill the cartridge or it will have constant error. Chips are available on line.

Turn the printer on. Remove the cartridges. Gently clean the electric contacts on the cartridges and the cartridge carrier. Put the cartridges back in. If the light is still flashing, and your printer won't print, one of your cartridges is faulty. I suggest you go to the refill shop and consult them which cartridges needs a replacement.
Does any message appears on your monitor when you try to print something? Usually, a message saying "problem with black/color cartridge" or something similar, that's why I am asking.

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.

The print head is fouled at this point , Did you refill the cartridge that came with the printer? if you did those are not refillable you have to buy special refillable cartrig. or you can dmage your printer.

Hello,
Have you tried to unplug your printer and plug it back in?

The counter needs to be reset most likely. I can\t locate a reset code & steps for you. Try calling samsung and ask about the toner reset you replaced the cartridge and its still showing the count from the old cartridge.

sir,
try to clean the cartridge on the copper side with tissue with and alcohol maybe the contact points doesnt meet or the cartidge itself is already defective. try also use an empty good cartridge just to to determine wich cartridge is defective.

yours,
alecz
