Common questions
What does the 544 error mean on a OKI printer?
A toner cartridge is missing, not seated, or not the type this printer expects. The number after the code identifies the colour. Refit the cartridge until it clicks and check the part number against the model before assuming it has failed.
Is the 544 error serious?
Not usually. Codes at this level normally clear once the condition they describe is dealt with, and a printer that carries on working afterwards has nothing further wrong with it.
Different code or problem?
Switch off and unplug a printer before reaching inside it. If a fault involves the power supply or internal electronics, or the machine is under warranty, contact the manufacturer or a qualified technician. Full disclaimer.
