I have just purchased a Konica ProC500 which is second hand but has had all PM kits added plus new dev. The problem is not the image itself its the amount of toner it is adding to the paper. I have tried all settings and at my wits end and so is the engineer. The copier is creating the right colour its just not adding enough toner in my opinion (Even though the engineer believes its the age of the printer) I know that this printer is capable of a quality image and even 10 years ago you could get a printer which would create a solid colour. Please, please help?
