Abstract:
An indication is received of a vacuum source level measured by a vacuum sensor in a printing device. The vacuum level is associated with a pulse-width modulation (PWM) level for a PWM controller. The measured vacuum level is compared to an expected vacuum level. The PWM level of the PWM controller is adjusted in view of the comparison to achieve a virtual PWM level.
