Remanufacturing the
HP LaserJet Pro M201, MFP M225
series toner cartridge (CF283X)
Technical Guide

In December 2013, HP released the LaserJet Pro M201 series. The M201 laser printers are based on a 26ppm, 600 x 600dpi
(1,200dpi with Fast Res) Canon engine. The CE283X is rated for 2,200 pages.
The printer itself has a very small footprint. It’s a nice small ofce/home machine. The memory is xed and not expandable at
128MB and 256MB for the MFP machines. The recommended monthly volume is from 250 to 2,000 pages/month. The printer,
when new, comes with a starter cartridge that is rated for 1,500 pages at ve percent coverage.
So far there are six printers based on this engine: the Pro M201n, M201dw, M202n, M202dw, MFP M225dn, and the MFP
M225dw. Cartridge troubleshooting will be covered at the end of this article.
