Hi guys need some assistance please
We've changed the drum, added new black developer , change the cleaning blade for the IBT
but still no look
please check images. I was browsing the forum and I see something about toner, that's the only thing I haven't changed. But we also cleaned the lens as well.

Did you replace the black developer unit or just replace the developer powder?

just the powder

Thats why you have poor K prints.

Fit a new dev unit & a new genuine toner.

If wanding the laser slit glasses does not help, you'll need a cyan and black drums. The test patterns help diagnosing immensely. =^..^=

The link doesn't work. It goes to a page where you have to "request access" to whatever you are trying to share.

I hope that you have learnt that trying to cut corners but replacing just the black developer power & transfer blade only you causing MORE issue.

If you were using genuine only parts you don't run into all these problems.

Did you have these black lines before you replaced the black dev & transfer blade?

The paper you are using looks 'glossy' have you set the correct weight etc?

Ok let me explain how it started. We were having these faded black prints and linea and thought that the issue might of come from the cleaning blade not cleaning Bel properly. So we replaced that. Then drum then powder then replaced full developing unit.
Never had those kind of lines before.
It was one of my staff who printed that and yeah I asked her if the gsm was correctly set.
Because again never seen that on that printer. In fact Konika been pretty good. Only issues is couple jams and it's slower than the Xerox C75, and with heavy weighted stock you have to manual duplex.
I'll follow up on the GSM issue and let you know. Only genuine parts we been able to get for this machine so that's all we use.
As I said we don't have a Konika tech on Island so it's only a Canon tech who checks it. Then found great advice on here

I'm going to guess that at some stage in this saga the black developer was over-toning, dumped toner in the second transfer roller unit. You can clean the second transfer roller with water, just make sure it's completely dry before re-installing.

See the repeating pattern? Is it the same length as the diameter of the second transfer roller?
