I'm having the EXACT same problem. The unit has not been used for about 3 years, and it worked fine before storing.
Now, it prints all colors on all color prints - even if I print a test page from the printer's menu.
I have discovered that if I print something grayscale from the computer, I only get gray lines.
Any help is GREATLY appreciated.
Hi, i bought a new xerox phaser 3 years ago, used most of the toner from the cartridges and retired the printer until now.
I did the maintenance mode like 3 times already, did the Auto-Correct the color registration, clean developer, a toner refresh for each one (twice), and a drum refresh.
I have pictures of a blank page print where it shows the lines, and also a color test page.
Thanks for any help.
