Fast checks

Start with the simple causes

Turn the printer off, remove the cartridge, inspect the chip or contact area, remove any protective tape, and reinstall the cartridge until it is fully seated.

Then confirm that the cartridge number and color slot match your exact Ricoh printer model. Small model suffixes and cartridge regions can matter.
