Re: Olivetti 4500i black copies
I'm not sure I follow you but from what I understand you have swapped developing units (300k) and still have black copies. Have you run internal prints? I am assuming OEM toner? I would make sure your process unit is grounded by using grease on the drum shaft. Sounds like an electrical issue to me. Also, TA-5500i -
Re: Olivetti 4500i black copies

Re: Olivetti 4500i black copies
Any time the machine makes solid black copies & prints, the developing unit will struggle to tone up the developer ("running on")
Fix the black copies and the running on will stop. =^..^=If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.
