Yes that did it. It doesn't show the wrong size anymore and not jamming so far.
In case others have the same problem....
Printed about 200 of 3 different 2 sided images.
First the black didn't come out so eventually found it was the toner was getting clogged in the cartridghe because it had not been used for over 2 years.
With a thin piece of plastic like a straw I opened the cartridge and loosend up the toner and did that also in the cartridge bed where the ink goes into the printer. It was clogged there too a bit.
Then created a A4 image for each of the primary colours and printed them on about 20 sheets each.
Eventually each sheet got better until it was solid colour.
Then printed off a some full colour fliers and they were perfect.
Thank you to gabiene who suggesed the Win 7 driver. I had tried many drivers but not that one.
Thanks, will do tomorrow..
As I have 2 machines the same, I have used the 2 image units and get the same result. One of the uinits is virtually brand new.
I have a feeling it is the driver that is causing it as both machines got the same problesm at teh same time. I can't recall what drivers I got down for them but I would like to get a 6250 DP drive from years ago so I could see if it would work better. I don't know where I could find a driver though.
You have any ideas?
It looks like the black developer unit which is part of the Imaging unit is the problem. So replace the Imaging unit.
For a while the black does not show or maybe extremely lightly at times.
I set up a black filled A4 page on CorelDraw and printed off a copy. It was virtually blank.
In Printer PropertiesI changed it from CMYK to RGB and it came out a very black sort of green.
I went back to CMYK and it was blank again.
Back to RGB I printed 10 hoping it woud get darker but it didn't.
I printed the Colour Help pages from the Printer LED but no black came out at all. Other colours were fine.
Any help please?
