REMANUFACTURING OKIDATA B410/B420/B430 IMAGE UNIT & TONER CARTRIDGE By Enrique Stura, Daniel Reyes and the Technical Staff at UniNet

The five models of the B400 series are particularly different from other printers on the market. The electro-photographic system uses LEDs instead of laser diodes for the creation of the latent image in the OPC. They also come standard with automatic duplex printing - a feature many other similar market printers would offer at extra cost. Other features include USB and parallel-port connectivity, which do not exist in competing models. Ultimately, the DN models are thus standard-equipped to allow connection to Okidata's own network called "Okilan." Print speeds in these models are rated up to 30 ppm. These models operate with a system of two consumable parts (i.e. toner cartridge and separate imaging unit), the resolution is 1200 x 1200 dpi. The LED heads are warranted for five years, and the rest of the printer is for 1 year. The B410/420/430 models have suitable monthly cycles of up to 50,000 impressions using 250-sheet capacity paper tray + 1 bypass, and a 500-sheet optional tray. The Okidata B400 series toner cartridges contain chips for both 3,500 and 7,000 pages.

Given that the toner supply slots at the bottom of these cartridges are very narrow, cleaning and refilling is very cumbersome. In this case, we recommend drilling a hole in the flat top section of the cartridge. From there, carry out the cleaning and refilling process.
