The ink in this cartridge is retained because the cartridge has an internal sponge. However, the sponge only fills the lower half of the cartridge. The upper half is an open ink reservoir.

On the CLI-8 and PGI-5 series cartridges, there is an electronic counter embedded in a small computer chip/board. This counter starts at a high number and decreases for every character printed. Eventually, the counter reaches zero. At this point, an error message is generated by the printer. If you click "OK" to the error message, the printer will continue to print. However, the ink level display will not show correctly with that cartridge. But that is something we have to live with. For most people, it is a small price to pay for a vastly lowered cost of printing.
