Hi guys,

Printer is Canon LBP2900 and the operating system on computer is Windows 8 beta. Recently, when I printer some files with it, there is a black line on the left side of the paper about 5mm faraway to the edge. No matter what I do, I can not remove the line.

Do you know why? How can I fox it?

Many thanks!

According to my own experience, it is likely that the dirty printing head or the narrow distance between the printing head and the marking roll. Not the problem of your windows 8 operating system.

So just do some cleaning work to the printing head and adjust the distance!
