Press the button on the chip-reset tool for several seconds until the LED light on the device goes off. Then, unlock the reset tool from the cartridge. Use the resetter with other cartridges and install them back into the corresponding slots in your printer. Voila!
InkRecycling.org is an online service that lets you recycle your empty cartridges for cash. Our team encourages you to take part in a worldwide movement to help our environment and earn some extra money while doing so.
Ideally, you should recycle them as soon as they`ve been used, as this stops the ink residue left inside the cartridge from drying out, making them easier to clean. The cartridges can then be refilled, re-sold and reused.
When you send a print job from your computer, the computer tells the printer where to deposit the ink or toner. If there isn`t enough ink or toner left in the cartridge, the printer will display a low or empty sign to indicate you should replace the cartridge soon.
Check the LCD print notification screen on your printer. Often, you can press the center button, or “OK” to bypass the low print warning and continue printing.
The most straight forward way to recycle your ink cartridges is to bring them to your local office supply store. Places like Staples, Best Buy and OfficeMax/Office Depot all provide cartridge recycling programs where you can earn rewards.
After all, expired printer cartridges from HP can be used without any problems even one to two years beyond the expiration date without any restrictions. However, once the printer cartridges are even older, you should overlook using them. This is especially true if your printer has a standalone print head.
1. Can you use other ink cartridges in an HP printer? It will depend on what type of “other” ink cartridge you intend to use on your HP printer. If it`s a third-party or generic compatible/remanufactured ink cartridge of the same model number, then yes, it will work.
You may clean the copper part and the contact points with rubbing alcohol. Power ON the printer and re-install the cartridge(s). Reset the printer to factory`s default configuration. If it is still not working, please re-install the CD, printer software and driver on your computer again.
The most common reason a refilled ink cartridge does not work is that you didn`t reinstall the cartridge properly. Check the cartridge and make sure it is not dislodged or misaligned. If there is no visible sign of misinstallation, remove the cartridge and reinstall it.
Many places accept your used ink cartridges for recycling. Several of the major “big box” retailers have ink disposal containers near where they sell their ink. Office supply stores also have recycling boxes or stations that accept almost every type of inkjet and toner cartridge.
Cartridge World is the leader in remanufacturing and refilling printer cartridges. We provide replacements for all major brands including HP, Dell, Canon, Lexmark and Epson. We refill ink cartridges for most home or small business printers, whether they are multi-function, color or black and white.
Disable the Cartridge Policy feature

In the Device Management pane, select the printers (or printer group) to configure. In the bottom navigation pane, select Config, and then select Supplies. In the Cartridge Policy section, select Off. Click Apply.

There are chips inside the original cartridges to record how many pages were printed and they cannot be reset. As a result the printer reads the chips and tells you that the cartridges are empty, even though they are not. This is why you are getting the “ink low” message even though the ink tank is at full capacity.

Toner cartridge full, printer displays: "empty needs replacing"
ANSWER : I once went to a customer who had a similar issue. They had installed new cartridges and judging from the box, they looked OEM. Strange thing was they felt empty when lifted and they were missing the chip on the outside that tells the printer it is installed and keeps track of how many copies were printed with that cartridge. The printer has no other way of knowing if the cartridge is full or empty.

run with empty ink cartridge
ANSWER : The only way is to buy a chip resetter and reset the chip on the cartridge. You can find them online for about $5. You just hold it against the cartridge until the light turns green. You do run the risk of damaging the printhead due to overheating because of no ink in it.

Waste Toner Cartridge is empty but printer is still telling me to replace it
ANSWER : All of the ones I’ve seen are optical. Light shines through a transparent section of the waste box onto a photocell. If toner builds up past that area, it gives a warning to replace it. Possibly toner dust has gotten on the photocell.
