Printing system with selective heater activation to enable ink flow to a printhead in the printing system

摘要

A method for operating a printer having multiple printheads includes activating a heater that is operatively connected to a printhead that ejects ink having a single color in response to receiving a print job. The printer detects the presence of colors other than the single color in image data received in the print job, and activates heaters operatively coupled to printheads that eject ink drops that correspond to the detected colors.
