I had a customer call me today that said their aftermarket toners suddenly won't recognize. These were installed toners that were working just fine yesterday, but a computer update came through last night and now this morning they dont work. She tried other aftermarket toners with the same result. The machine is hooked up wirelessly. I'm thinking a firmware update from HP installed and is blocking them. I have a lot of the M452s/M477's in the field, is this something I can expect in the future, as they all use the aftermarket toners. It's the only cost effective option in these models. Is there anyway to bypass this with a setting that I don't know about? I know HP changed the newer M454/M479 models so that only OEM toner can be used so they can make all that money, but retrofitting the older ones without customers knowledge is just a crappy thing to do.
