TRAY/DOOR SENSOR

HP A7W93-67040 Tray/Door Sensor is a replacement service part for monitoring tray or door presence in supported PageWide printers. It is identified in HP service guidance for Tray 2, Tray 3 and high-capacity input tray sensor instructions.

The sensor supports the printer’s door-state check: the service test should report Closed when the right door is shut and Open when it is open. The part is listed for models including E776dn, E776z, 765dn, E75160dn, 780dn and 785f. It is a practical repair component when the relevant sensor test indicates that the tray or door sensor needs replacement.
