Samsung CLP-500 Printer Problem

[Cmitchell]

Hi, we've got a Samsung CLP-500. Everytime we print, the finished document comes out with pale faint vertical stripes. We've already emptied the toner waste tray (and cleaned, dried & replaced it). It's still doing it. Any suggestions? All sugestions much appreciated. Merry Christmas C x

It's nothing to do with the waste toner. It's most likely that the toner cartridges containing powder has not been transferred properly to paper in previous prints. The toner drum is therefore dirty with residue powder on it. Take out the toner drum which is a cylindrical greenish cartridge and use cotton buds soaked with isopropyl alcohol to clean the dirty area. Make sure everything is dry before placing back. If this doesn't work, or you again get vertical lines later after printing, you'll need to replace the whole drum which can be costly.
