What type of toner are you using? As far as I know, most
toners for xerography or laser printers use about 50%
iron oxide and the rest is plastic and other binders. The
toner needs to be magnetic because it depends upon
being moved around by a magnet to deliver it precisely
to the copier drum. Some formulations are purported to
be more magnetic than others, for use in printing checks
with magnetic tracking numbers, but as far as I have been
able to tell this is mostly a scam to charge a higher price...
regular toner is pretty much the same thing and is supposed
to work just as well.
Anyway, the toners I've tried firing come out brown, and fairly
light at that. I was hoping to be able to laser-print onto transfer
paper and make my own decals, but so far no luck. Haven't
gone to cone 10 though, only cone 6.

Back in the early 90's I worked for a company that developed one of the first PC check printing software packages to be used with desktop HP Laser printers. While there is a small amount of magnetics in a regular toner cartridge there wasn't near enough to be read properly by the MICR readers. We had to buy special toner that could be be read by the MICR readers and use it in our cartridges. We also had to have our own readers to test the ink to ensure that our cartridges could be read by the banks and other financial institutions so I know for a fact that there is a difference in the cartridges used for printing checks compared to standard toner cartridges and that it is not a scam. Of course there could be some business that may be selling regular toner cartrdiges as MICR toner cartridges but the users of those cartridges would be getting back unprocessed checks and nastsy letters from their banks along with some extra bank charges.
