Oki 320 Turbo data light does not turn off alarm?

I have a Okidata 320 Turbo 9-pin printer and alarm light started blinking for no reason and not be quenched. What could have caused this? It was the impression that it happened.

Or you have a paper jam, but since you said "no reason" probably not be the case. If you are still able to print, probably means you're low on ink and it's time to buy a new cartridge. If you can not print everything that is out of ink. It could also mean that using refilled cartridges. Hope this helps
