Printers that take 30% Fe Oxide Cartridges are: HP Laser Jet Pro M102W / HP Laserjet P1102w / HP laserjet Pro M102a / HP laserjet Pro M130a / HP laserjet Pro M130fn / HP laserjet Pro M130fw / HP laserjet Pro M130nw (i.e available at NES Printer Specialists in Castle Hill for $138.00. www.nesonline.com.au. Ph +61 2 98947158. The toner cartridges are sold at TonerCity.com.au).
We recommend only Canon or HP Black-Only (mono) printers as these are the only ones that have enough iron oxide/ferrite in the cartridges (above 30%).
Canon: ANY black and white laser printers are safe to use
HP: MOST black and white laser printers are also compatible but make sure to avoid any that describe their technology as “LaserJet Flow”, “Managed”, or “Never Stop”. And the HP model numbers to avoid (as of Dec 2020): HP LaserJet 103/107/108/408, HP LaserJet MFP 131/133/135/136/137/138, HP LaserJet MFP M440/MFP 432/M437/M438/M439/M442/M443, HP LaserJet MFP M42523/M42525/M42623
The printer must also specifically be “Black-Only”, and not a colour printer set to black-only mode.
