Photocopier adjustment presets

You seem to be considering substituting a physically different toner/drum/etc cartridge. Why?

Toner can be bought in bulk for most machines...along with instructions for re-filling the cartridge and refurbishing (within limits) the drum (if it is in the cartridge). (ex:

It would seem so because these sites mention "photocopier" toner but they're all geared up for laser printers and barely mention of any photocopiers unless they are the combined printer/fax/copier sort. It would be nice if a toner source company like Katun published a compatability list of their bulk toner types. But of course that is commercially sensitive info, so the "value added" companies down line can decant into the machine specific bottles. I've plenty of these bottles which incidently also show that this particular machine must be coming to the end of its supported life. The bottles must be recycled because the archimedian screws are getting more and more prone to jamming presumably due to wear in all the previous machines. I've decided to get a technical manual anyway to be sure what preset does what but there is a complete lack of info toner types as far as I can find so it will still be suck-it-and-see what happens. I cannot even find a way of testing toner to determine its characteristics outside of a machine, eg dustiness, oiliness/silicones (affects the amount of corona/transfer voltage required , as far as i know only added to makesure the fuser and associated pressure roller stay clean ), fuser/melt temperature ,conductivity (for triggering refil and full surplus bottle switches) - those are just my guesses for some of the characteristics. anyone know of how to do such testing especially dustiness/oiliness/claginess test, I don't even know what its called - If you blow on a small pile of such toner it will blow away but not as easily as if it was totally dry dust of the same particle sizes.

Twiddling presets when you dont know what youre doing is not smart. Nor does it have much to do with toner types. Toner can be hot fuse or cold fuse, with most machines thus most toners being hot fuse. Just try another toner, or more sensibly buy the right toner from a replacement supplier. There are various companies that supply toners etc, and they dont take the slightest notice of manufaturer EOL dates.

As for all this 'end of supported life' twaddle I wouldnt take too much notice. There are always companies around wiling to repair used machines, and availability of parts from sources other than the mfr usually goes on for a good decade after their so-called EOL dates. And you'll probably find them far cheaper than Tosh.
