LaserJet 4050TN Print Quality

[i12av82]

I've done a few searches, and part of the problem is I do not know how to describe the issue well - so here it goes!

Lately my 4050TN has been printing some lines normal, then other lines of text lighter - here's a picture (I apologize for the quality):

Any ideas where I should start for this? Most of the documents I print out are now unreadable.

Thanks!

Picture looks great.
Have you looked at the fuser?
If it looks good, try the half test

Two most common sources of print defects are--
The Toner cartridge, then the fuser...

Here is a quick tutorial on doing a halfway test to determine where in the print process the defect is occuring:

If not the toner cartridge, the transfer roller might need replacing.
