I have changed nothing exceopt turn it off for a few days then on again and replaced the new maintenance roller kit.
The colours are much darker on the new print and there is a smudge of blue on the yellow label. Even the whole page seems to have a lint look to it.
Compare what was done a month or so ago and what is now.
Tried plain yellow 1/2 A4 and 1/2 A4 dark blue on same page and it was clear as a bell.
Why does it do this smudge on these images please?
Same image tried from CDR and also from PDF.
Even other images come out much darker. 8570/8870 Series Class
The driver is 8570/8870 Series Class.
I tried to change to a 8570 DN PS driver but it says Printer Setting could not be save. It is not supported.
Go to Solution.
Well, I took that PDF above to another PC with the same Win 10x64 OS and printed it out.
It came out correctly,. not too dark as on the initial PC.
I checked the drivers and found that the first PC had..
the Windows Class driver whilst
The correct one had CQ8570-8870_PS_x64(exe)
So I answer my own question. Each PC has it's own print driver.
Smudge gone and correct colour
