Print quality is bad.
I started having 3 dots going down the middle of the pages. So I cleaned the inside of my laserjet with alcohol as described in the manual. Then my pages became worse. Some shadowing or light shaded lines. I've ordered a new tonor cartridge in hopes that the problem will be corrected. Any other suggestions?
3 dots are a nick on the cartridge drum. Other symptoms are a bad drum wiper blade. Replacement cartridge should fix it.
