Title:
TEMPERATURE CONTROL CIRCUIT FOR AN INKJET PRINTHEAD
Document Type and Number:
WIPO Patent Application WO/2016/021188
Kind Code:
A1
Abstract:
A temperature control circuit for an inkjet printhead including a temperature sensor portion that generates an output current(IM40) made up of the sum of a current proportional to a sensed temperature on the inkjet printhead and an offset current, and an offset current correction portion that generates a correction current(IM16) that is subtracted from the output current(IM40) to at least partially compensate for the offset current, the output current(IDIFF) as compensated by the correction current being output as a temperature control circuit output current.
