What I have done so far: Run Clean Fixing Assembly multiple times, Run Clean ITB multiple times, changed toner cartridges, updated firmware, hard reset to factory settings, printed from different computers
I'm not the original poster, but same problem, same printer, only my stripes are black only. It's not the toner, I changed it plus the stripes are completely random. I'm running Windows 10 and cartridges are 045.
Same problem here, mine look just like yours but only black. It is NOT the toner. I changed the toner, plus it's totally random. It will print two pages clean, then several with these streaks. Same printer, running Windows 10.
