In January 1996 Xerox released the 8 ppm DocuPrint 4508 Personal Laser
printer, aimed at the "personal corporate" desktop laser market. It replaced their 5 pages per minute (ppm) 4505, which was retired in February the same year.
Instead of a Fuji-Xerox® engine, the monochrome 4508 utilized the
familiar 8 ppm QL-85 engine from the Samsung® QwikLaser 84/85 and 6000
models. The compact footprint, along with the excellent price and performance of the Samsung engine made it much more attractive than the Fuji-Xerox engines used in nearly every other Xerox desktop laser at the time.
The 4508 utilizes a single piece "all-in-one" cartridge using a non-magnetic microfine toner. The fuser is "user-adjustable", allowing the user to change the fusing temperature to optimize their print quality when using different paper stock, which can have varying heat transfer characteristics.
Remanufacturing the 4508 cartridge is fairly simple, since the 100% toner transfer eliminates the need for a waste bin and there is no recovery blade or wiper blade.
