    By Mike Josiah and the Technical Staff at Uninet

    The HP LaserJet PRO M203 series of printers are based on a monochrome 30ppm, 1200DPI with HP fast Res or Pro Res). The first page out is stated to be under 6.6 seconds, and all “W” models so far come with Wi-Fi, Apple AirPrint, HP ePrint, Google Cloud Print 2.0 built in.

    All machines released do far come standard with 256Mb (fixed) memory and have a duty cycle of 30,000 pages per month.

    As with the M102, this engine is a big change for HP Monochrome printers in that there are separate Toner and Drum cartridges. Typically HP/Canon have used “all in one” type cartridges for monochrome printers. Both the toner and drum cartridges are small and not rated for many pages so even though this is sold as a low volume machine, I believe there will be a decent demand for the cartridges. The cartridges are simple and fast to remanufacture.

    There are two toner plus the drum cartridges available for this engine. The toner (CF230A, CF230X) and the drum cartridge (CF232A). The A toner is rated for 1600 pages, The X is 3500 pages. The drum unit is rated for 23,000 pages. The starter toner cartridge that comes with the printer is rated for 1000 pages.

    The drum units in this series do not have a conventional waste chamber. There is a coated felt cleaning brush under the PCR, but that’s all there is. Under the brush there is a chamber but the clips for the PCR and cleaning brush clip run through the outside wall and are not sealed. This system is almost a Zero waste system.

    These drum units also come with an internal erase lamp assembly. This lamp erases any residual charges from the drum
