Abstract
An ink jet printer of the type having at least one customer replaceable ink cartridge with an ink monitoring system detects whether or not the ink in the cartridge contains qualified ink or not and adjusts the normal printing mode to a non-normal printing when non-qualified ink is detected, thereby providing the customer the option to print with non-qualified ink with minimized effect on the printer or print quality.
