Questions about this item

What limits the sensor's lifespan during continuous printing on the PX720?

The printhead sensor is a consumable component; its operational limit is reached when the internal detection element degrades from prolonged exposure to ink and mechanical cycling during sustained printing on the PX720.

How much heat does the sensor generate during all-day operation on the EP-904A?

As a passive detection device without active electronics, the sensor itself generates negligible heat during continuous use on the EP-904A; thermal load comes from the printhead assembly, not the sensor.
