Verifying a maintenance process on a print head |
摘要 |
The present invention is embodied in a printing system (100) that includes a print head (120) having a controller (110), a temperature sensor (116) and a priming system (126) configured to apply a fluid pressure externally to the print head (120) to purge the print head with fluid, wherein purging the print head (120) with fluid has an effect of reducing the print head temperature. The controller (110) is configured to activate the priming system (126) for purging the printhead (120) with fluid, monitor a signal from the temperature sensor (406), and determine (418) whether activating the primer has resulted in sufficient fluid passing through the print head (120) based upon monitoring the signal from the temperature sensor (116).
