The HP LaserJet MFP M436n and M436nda monochrome multifunction printers (MFPs) have OEM-rated print speeds of 23 pages per minute (ppm) and monthly duty cycle ratings of 50,000 pages. The only difference in the two machines is that auto duplexing and an auto document feeder are standard features on the M436nda model.
Both models share the same toner cartridge and drum unit SKUs. Replacement cartridges are available in 7,400 page standard yield and 12,300 page high yield versions. Drum units yield 80,000 pages. Both models ship with one 4,000 page yield introductory cartridge and one drum unit.
Both cartridges and drum units require a chip for correct printer operation.
