4250N "Non HP Supply Installed"

We have (3) of these HP LJ4250N printers. One was running low on toner so I swap toners with a less-used printer in the corner.
One printer's happy, says "Ready".
Other printer says "Non HP Supply Installed. Economade disabled".
-Tried turning off printer for 5 minutes, same mssg.
-Made sure nothing was in way of 4 contacts on toner cartridge.
Both toners are genuine HP Q5942A toner cartridges, came with the printers we bought New just a few months ago.

Re: 4250N "Non HP Supply Installed"


After a toner cartridge reaches a "Low" status (as it appears on the screen) the chip on it gets written over. If you switch this toner to another printer it will indeed detect it as a non-HP supply. The reason? The printer has no way to tell at that point if the cartridge has been refilled or not.

So, the situation you see is expected behavior. You can continue to use the "Low" cartridge until out without issue. It will simpyl have the message on the display.
