How do you clean a printers rollers?

Do you need 4 different toners for laser printers or just one? + Best laser printers? (read description)?

• i've had brother inkjet printers for my whole high school life and they've always been reliable, i've had 3, don't remember what happened to the first one, the second one was fine but then we upgraded to a wireless version .. a few days ago we found out the wireless one stopped working .. not sure why but i have so many assessments to print so i got my old printer back from my cousin who bought a laser printer and recommended getting a laser one. The one he gave us is printing fine but has a vertical ink line on the back of each page .. and its so dark it goes through to the front so i pretty much can't use it any more. i've been looking at some laser printers online .. whats the best brand for laser printers? most of the ones i'm seeing are HP, brother or fuju xerox (which is the one my school uses). I had a hp laptop which failed on me so i'm leaning away hp products. leaning towards the fuji xerox Cp205 wireless printer http://www.officeworks.com.au/retail/products/Technology/Printers-and-Scanners-and-Faxes/Laser-Printers/Colour-Laser-Printers/INFXCP205W its pretty cheap compared to most of the other laser printers i've seen. has anyone had a fuji xerox laser printer? is it good? what printer would you reccomend? also .. in the information it says Consumables: FXCT201591, FXCT201592, FXCT201593 & FXCT201594 does that mean each one is a different colour toner? black/magenta/yellow/cyan ?? does it need 4 different toners or just one?

• Answer:

  You DO need four separate cartridges, my friend. There's an advert below that shows thee cartridges ... in Australia, even though you asked your question on Yahoo! Answers United States.
