Hi, how's it going ... when you have to downgrade it because the machine's firmware was updated, it turns on the same but the problem it does is that it doesn't take you the alternative cartridges, when the fault is a play of lights ... the problem is almost sure it is because the page counter or boma counter came to its useful life ... you have to reset these counters through a special program ... I leave it to you ... always remember to deactivate the antivirus when doing these processes greetings .....
