A Simple Hack to Transfer HP 564, 920, 902, 934 and 935 OEM Chip into a Chip-less Cartridge
Many users want to transfer HP's chip to a 3rd party cartridge.  The new HP chips are notoriously hard to remove.  The chip is embedded in the cartridge.  Traditionally, people remove the chip by heating it up with a heat gun and melt the bonding glue. 
However, there are some drawbacks:
  1. Heating the glue may also damage the chip. 
  2. Even if you removed the chip successfully, you would need to buy a chip adapter (aka blocker or holder) to secure it on the new cartridge.  In this video, we tried a cold method. 
  3. The transferred chip may not line up correctly with the printer.

Our goal is to find a safe and easy method for the chip transfer.  We are going to show you how to transfer chips from newer HP cartridges.

How Can I Reset an HP's Cartridge Ink Level to Full?

How Can I Reset an HP's Cartridge Ink Level to Full?

Most HP Inkjet cartridges come with embedded chips, such as the older model 564, 920, or newer 932, 933, 950, 951. The chips have two primary functions. One function is to count the number of pages printed and prevent the printer from running out of ink. A printer has no “ink gauge” or “ink sensor,” even for advanced models like 6700, 8610, or 8620. The printer estimates the ink level by counting printed pages. Then, the chip saves the information, and an estimation is made. If you transfer the cartridge into a second printer, the printer will estimate the same ink level.
