Cons: Indicates it requires service in less than a year. The red LED light is illuminated, and won't turn off. I replaced the toner cartridge, changed drivers, etc. The "help" is very limited in what it will tell you is wrong with the printer. A solid LED indicates either a paper jam, no toner, or a critical error. Would have been nice to know it was a critical error prior to purchasing a replacement toner cartridge.
