Tools Needed

 Symptoms: Your printouts have a faint smudge down the page--the heavier the paper stock, the darker the smudge. Cleaning the corona wire inside the toner cartridge doesn't help.

The problem is easier to identify when printing envelopes. After printing, the envelopes have a distinct outline of the envelope where flap and paper is folded (see picture below.)

Cause: This problem is caused by a combination of a worn Transfer Corona and the low humidity/high static electricity in the air. The high static electricity causes loose toner paticles to go where they shouldn't--especially when the paper is thick and the Transfer Corona can't deposit a sufficient charge to repel them.
Phillips Scewdriver

Workaround: In most instances, turning the Green Density dial down to 3 or 1 will solve the problem. This will increase the charge in the Transfer Corona. You can also reduce this problem by putting a humidifier near the printer.

Kit Description: The kit involves replacing the Transfer Corona assembly. It should last about 100K pages.
