Hi again,
1. documents from Word print also with strips
2. printing from another computer with MS Windows 7 makes the same troubles;
printing from another computer with MS Vista prints ok, there are no troubles at all
3. usually I use normal paper for printing anything
printer is printing not black strips but colour off strips in 2 colours: red and blue. Yellow and black seems to be ok.
If I print just red without any diluting shade, it prints ok. As soon as it is bit lighter, it makes off colour small strips (also in Word).
I was sending some informations to HP support, so we will see what they will find out.
Thanks for help!
