Does anyone know if one can purchase MICR toner for the Ricoh MP 301SPF?
Hey Art! I don't know about MICR toner for this specific model, however what models in general are MICR supported? Last I knew Ricoh had a larger BW box that was MICR enabled, but couldn't find anything about it. Did find some outfit out on the West Coast that would retrofit a BW Canon for MICR, but we never went that route due to them not being authorized and didn't want to jeopardize Canon service support. MICR's an interesting niche that is still necessary though.
I don't know if it is as simple as just adding a MICR toner...I know you can put standard toner in a MICR printer but I don't know if you can do the converse. All the Ricoh MICR printers we have purchased have been through Rosetta Technologies. You can contact them here
I recently sold a few of the smaller Ricoh printers (not from Rosetta) and have them using the Rosetta MICR cartridges. There is a small tab on the cartridge that needs to be removed.
back in the day I use to reman cartridges and I know you can or could buy MIRC toner for almost any printer or copier
