Ok, machine was having magenta toner issues, tried new cartridge with same result, then replaced toner pump. Immediately fixed, or so I thought. After replaced the pump it showed full toner and everything was fine with td levels and my test prints. Left and after about an hour the client called back that again magenta was out! Eh??
any ideas? Maybe bad developer unit because toner pump wasn’t working? But if so why did it work fine for a little bit?
