I have two LaserJet 1536dnf printers that never had the error 79 before, and now I upgraded to the latest firmware and it's causing error 79 over and over again...even when I'm not actively using the printer!! I can't use either printer anymore. The machine just keeps showing error 79, then automatically reinitializes and repeats this process over and over. The new firmware has broken both of my printers!!
