I'm getting blue streaks on both sides when printing in color HP color LaserJet cp1215.
No blue streak if I print B&W. Or if I want to print a color pdf of the Paris metro system or any Google map, it prints a grey -black area where the street map should be.
I have HP Pavilion PC , windows 7.
Have done windows printer test page and the Microsoft Office Basic Colors test; tried printer troubleshooting tools. No results. I'm not a techie. Just average person trying to make my printer work as it did before.
Any help?
