Corosol technology is older,slower sounds also too high, it is not suggestible to lubricate the moving parts because of cartrides will move while printing result lot of toner particles raises in printer chamber,if this particles deposited on lubricated area will abstract the moving spares. If you can do the periodical maintenance, use silicon grease for moving parts..
The HP Color Laserjet 2840 Is a Very Good Reliable Printer. I'm curious if you are buying American made components or cheap components from some thrid world country sold at ahuge retailer. They really should stand behind their laser drums, but if they don't then shop over at www.officeinks.com or www.wowsuperdeal.com and Purchase American Made Toner Cartridges and Laser Drums. Office Inks has a 1 year satisfaction and quality guarantee and free return shipping if their ink, toner, drums, ribbons etc, don't make you happy. Only Ships USA Though.

The front panel tells you witch toner cartridge should you replace. If a supply memory error ocures then the cartridge should be replaced or exchanged with a new one. The imaging drum unit is also consumable. for "Joe 50" - there are 4 toner cartridges in the printer.
