Abstract
A semi-conductor chip for a print head, including: a plurality of LEDs; a drive circuit for supplying electrical power to the plurality of LEDs; and a control system calibrated to supply, using the drive circuit, the electrical power at a first magnitude to every LED in the plurality of LEDs and configured to: receive a first external clock pulse less than a second external clock pulse used to calibrate the plurality of LEDs; change the first magnitude to at least one second magnitude proportional to the first external clock pulse; receive a third external clock pulse different from the first and second external clock pulses; and energize, using the drive circuit and in response to the third external clock pulse, the plurality of LEDs for a first internal strobe time at the at least one second magnitude calculated by the control system.
