Question about Canon NP 6545 Copier
The developer unit is looking for toner from the hopper. E020 can also be the DC Controller or the developer unit itself. The toner cartridge is probably fine. This can be complicated to fix. The copier is probably still under warranty. It's better to call up Canon 1-800-828-4040 and have them send out a Certified Technician to fix this. Sorry I couldn't help more. Ray
