HP 218 error messages: what they mean

Start with the physical checks: remove the cartridge, make sure all packing tape and the protective cover are off, and reseat it firmly in the slot whose color chip matches the cartridge. A dirty or damaged chip contact can also cause it.

If it is a compatible or remanufactured cartridge that stopped being accepted after an update, the likely cause is dynamic security — contact the seller for a replacement or refund. An Original HP cartridge that is still rejected needs HP support.

They are estimates from the cartridge chip. HP calls the levels "estimates for planning purposes only" and says you do not need to replace a cartridge until print quality becomes unacceptable — "low" is a reminder to have a replacement ready. Gently rocking a cartridge near the end can redistribute the toner for a while.

Remanufactured cartridges that reuse a reset HP chip may not show toner-low messages at all (Staples says so for its 218X).

Levels come from the cartridge chip, so a remanufactured cartridge with a reset or reused chip, or a compatible chip, may report nothing or something inaccurate. With an Original HP cartridge, reseat it, then update the display by restarting the printer. If the level stays wrong, print by quality: replace when output fades.

A chip problem shows up as a message before or right after installing: "not recognized", "unsupported", "used or counterfeit" or a cartridge problem — often while the print itself looks fine. A toner problem shows on paper: streaks, faded areas, a missing color — with no chip message.

Test it: install a cartridge you know is good (preferably Original HP). If the message disappears, the previous cartridge's chip was the problem. If print quality stays poor with a known-good cartridge, work through HP's print-quality steps (cleaning page, paper, settings) — the problem may be in the printer.

Often, but with a real risk. HP labels the 3201dw and 3301 models "dynamic security enabled": HP says such printers are intended to work only with cartridges that have new or reused HP chips, and that firmware updates can block other cartridges — including ones that work today.

Remanufactured cartridges that reuse an HP chip (Staples, Clover) and compatibles with their own chip (Swift Ink, True Color Toner, INKFUN) are sold for these printers. We have not tested any of them; we report what each seller states and what its return policy is.

The chip tells the printer which cartridge is installed and tracks the toner level. On dynamic-security printers it is also what the printer checks before it accepts the cartridge.

For compatibles we show four chip states from the listing: chip included; no chip; move your old HP chip over; chip not stated. Only "chip included" counts as ready to install, and none of them guarantees the cartridge survives a later HP firmware update.
