Pantum: Toner Cartridge Not Installed
What it means
The printer cannot detect a cartridge. On a new machine this is usually the protective packaging still in place, or the cartridge pushed in but not clicked home. Remove it, pull off any tape and seals, and refit it until it seats with a click.
A full step-by-step guide is on the way
We publish guides only after checking each step against the manufacturer's own documentation, so this one is still being written. In the meantime, if the code relates to a jam or an obstruction, switching the printer off, unplugging it for a minute, and checking for anything stuck resolves a large share of cases. For a hardware fault, contact the manufacturer.
