Classification: CPC B  G | IPC B  G

Claim 2:
3. An inkjet printer, comprising:
a printhead assembly comprising a printhead and an imaging system, the imaging system comprising a camera and a strobed LED source; and
a deposition unit for positioning a substrate to receive droplets dispensed from the printhead and for imaging the droplets on the substrate using the imaging system and the strobed LED source, the inkjet printer further comprising a controller configured to:
during a scan process wherein the substrate and the printhead are relatively scanned,
activate the strobed LED source, illuminating an area of the substrate for a duration selected to ensure any distortion from relative scanning of the camera and substrate is much less than a typical dimension of the droplets being imaged;
deactivate the strobed LED source after the duration; and
reactivate the strobed LED source after a time selected to ensure a previously un-imaged area of the substrate occupies at least a portion of the field of view of the camera.
