ir7095 duplex

[jiongpao]

Hi everyone,

Its about 3 days ago one of the ir7095 got blur only printing or copying in double sided mode using platen glass. Theres no problem with single sided even in few hundreds copy. But when it came to double sided, it blur horizontally on beginning of B side and almost in every pages.

This problem remain same when i changed HVT-DC/AC, pre-transfer assy, transfer assy, separation assy, dust proof glass, developer rear clutch,
Can anyone please help me on this.

Re: ir7095 duplex

The Mashine alters the transfer and sep currents in duplex mode, for me it looks, like you are working in an almost damp area. Try the following: lower the two sep wires 1mm each and raise the transfer wire 1mm, that should do the trick. You will have to try out the position of the sep wires, if they are too low, you will get three black marks at the front of the page, because the sheet will flap up and touch the drum separation claw assy.

Service Mode :
COPIER - OPTION - BODY - TRNSG-SW ENTER 2 OK (default = 3).
I have done this and minimize the blur.

Hi, i tried on lower the two sep wires 1mm each and raise the transfer wire 1mm and the result is fine till now but i will going back tomorrow to monitor again and try on enter the value 2 for TRNSG-SW and see hows the feedback.

Re: ir7095 duplex

Hi, the problem still the same even i played around with transfer and separation highness but it solve when i set value to 2 at COPIER - OPTION - BODY - TRNSG-SW. How does it work with TRNSG-SW?

Re: ir7095 duplex

It is just an experience with the old IR105 which is identical with IR7105.
If TRNSG-SW is set to 2, the Transfer Guides is biased at only 200VDC causing the weaker attraction of the Separation Coronas, giving more chance for the toner transfer to paper.

Re: ir7095 duplex

There is one thing i forgot to mention, as you replaced the corona assys, did you reset the counters in service mode too? this is very important, because the mashine adjust its corona currents in depending of the counter value.

I did not know that, although I zero my counts to make it easier to know what to replace

I did'nt reset any counter after replacing every corona wires. How do i do that?
