Hi,

Please print CMYK, not RGB. In my opinion there is a problem with cyan (imaging unit or laser),

Hi,

When this problem appears, I ordered and changed the Image Unit. So it's a fresh one. I add two prints with cmjn colors. It's the same image with a 180° rotation. You can see the same effect on black and cyan rectangles. Not visible on magenta and yellow. I changed my black cartridge with my backup one, I got the same problem. I tried all appropiate functions on maintenance menu, clear developper, uncharge toner, nothing works. It's a big mistery.

It would be very sad to not use this phaser anymore , it's a good machine

Thanks for reply.

Hi,

Behind the imaging unit there are 4 little windows (laser windows). Try to clean them with a dry cloth.

Hi Gaby,

I done it. I carfully removed the unit.  Behind, I found 4 large spaces and 8 smaller. I carefully clean them with a dry cloth, I used a pen with a gum to help the cloth to gon on the spaces.

But the result is exactly the same. I don't understand what can be wrong.

Thanks for your help.
