Even if the cartridge is refilled to full, the printer will still remember the old page number.

HP protected the chip data with 128-bit encryption, making it impossible to reset the page number.

The chip's other function is to prevent a cartridge refill. 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.
