"Works well but supplies are expensive"2.0 starson by scotl
Pros: Prints fast and pages are crisp and neat
Cons: Toner is very expensive and so are drums. It will tell you to replace the drum before it is worn out (still printing perfectly) and will not print any more until you do so.
Summary: I searched for hours to find a way to reset the drum counter on the B431 but it still remains a secret. Other Okidata printers have been solved but not the B431.
All printer manufacturers are trying to lock the customer into buying their overpriced ink/toner/drums. They'd like to void the warranty for using any supplies other than their own but they can't because of the Magnuson-Moss Warranty Act. Section 102(c) of that Act expressly prohibits inclusion of a tie-in sales provision in any warranty as follows:
No warrantor of a consumer product may condition his written or implied warranty of such product on the consumer's using, in connection with such product, any article or service . . . which is identified by brand, trade, or corporate name... .
I don't know why some ambulance-chasing lawyers haven't slapped lawsuits on all these printer manufacturers that are including chips (namely - all of them) in their consumables that force you to use only their products and force you to change them before you even need to.
