Sometimes, you need to upgrade or downgrade your firmware or reset to a factory setting. Of course, this apology letter was titled "Dedicated to the Best Printing Experience." Thanks for the experience, HP! So, there is always a way you just have to know it. Here is their apology letter ( HP's apology for not letting customers use refilled cartridges). They issued an apology immediately and released firmware to enable the use of non-HP cartridge chips. In 2016, HP accidentally killed off all non-HP chips in the 934, 935 and 950 models. Otherwise, they will be in contempt of a court order. Not all the chips can be reset or overridden, but HP will always leave a refill solution for you. To summarize, all (or almost all) HP's cartridges are refillable. You could also use a third party refillable cartridge or Continuous Ink Supply System also known as a CIS.

On BCH’s website, there are detailed instructions on how to do just this. You can simply refill the original HP cartridge. There are two ways to move away from expensive HP ink. Paying for a new cartridge for more ink is wasteful when the cartridge is perfectly reusable and is also expensive if you consider HP prices for a brand new cartridge. There is a lawsuit claims that HP mixes color inks to print black, so customers cannot just print blacks and do not buy color inks, detailed information can be found at Consumer Reports and. After losing both lawsuits and paying millions of dollars, HP now allows the cartridge to keep printing with “empty” chips, but consumers must figure out how to turn off the ink level monitor on the printer. A second class-action suit claimed that HP shut down cartridges even when ink remained. In 2010, a class action lawsuit accused HP of making printers showing low on ink even when they weren't. How nice is that? HP wasn’t so nice earlier. However, HP will allow you to refill their cartridges.

To counter this problem, HP used to make 564 and 920 cartridges with little windows on the sides. On the other hand, you may have no ink, but HP says you still have some. Therefore, you may have plenty of ink when HP says your cartridge is empty. For example, if your 564 magenta cartridge is supposed to print 300 pages, and your cartridge logs 150 pages, then the printer will say it is half empty. It is simply calculated by counting how many pages the printer has produced, which is logged by the chip. The cartridge has no “ink gauge” or “ink sensor,” even for advanced printers like 6700, 8610, or 8620. Chip's primary function is to count the number of pages printed and guess how much ink is left in the tank. If you transfer the cartridge into a second printer, the printer will estimate the same ink level. Then, the chip saves the information, and an estimation is made. The printer estimates the ink level by counting printed pages. A printer has no “ink gauge” or “ink sensor,” even for advanced models like 6700, 8610, or 8620. One function is to count the number of pages printed and prevent the printer from running out of ink. Most HP Inkjet cartridges come with embedded chips, such as the older model 564, 920, or newer 932, 933, 950, 951.
