Laser Printers are complicated machines, when they age things can go wrong - mostly to do with the Drum Unit.

If you're experiencing any of the problems listed below, it's time to replace it with a new one, there is no economical or reliable way to repair a damaged or worn out unit. See our range of Drum Units in the Toner Cartridges category on our home page.

1.) Dots or imperfections that repeat down the page.
The result of a chipped drum surface, can be caused by paperclips, staples etc that tend to find their way into office printers.

2.) Gray page with toner powder residue visible on the drum.
Drum units contain a wiper blade designed to remove excess toner from the printing process, over time these blades tend to stiffen.

3.) Light gray smears over the page, tracks down one or both sides of the page.
These are purely symptoms of wear and tear, most printers drum life is 10 times that of the laser toner cartridge itself - if you have used this many toners the drum will probably be due for replacement.

Most printers have a separate warning light for drum replacement, look for this for confirmation of the problem before replacing it as they can be quite expensive.

In the case of most entry level laser printers it is often more cost effective to just replace the whole machine so make sure you check the price of the new drum vs a new printer first!
