Hello,
The story starts with IU printing with poorer quality. It works though, jst not to expectations see pdf oldIU610BK-sample.
So I have ordered brand new one and put it in it came as a failure to produce correct sample as if the HV leaks to one side and I had a toner band arround the Bk crum far back in machine. OK maybe faulty Imaging unit. Replacement came in and ditto the same just different approach see newIU610BK-sample
Have taken the print head out and found smoe dev drop on the slit glass, did a complete clean up inside out where the print head sits. No joy. Changed ITB and TR. Full stabilisation, background reset, gradation adjust, even with the fault, still no improvement. Played with 1st fine adjustments. No Joy. Put the OLD IU back in place and just had the same worn mark as per sample oldIU610BK-sample. Checked all grounding contacts and cleaned them on door, IU's, ITB, TR.
I am suspecting HV unit, just not sure 100% before I order one. Has anyone came across on of these problems? Thanks for any heads up. Cheers
Happy St. Nicolas Day to everyone, have plenty of chocolate!
