Document feeder hinges
The document feeder hinges allow positioning the assembly vertically above the scanner glass to
accommodate the placement of books and other objects up to 25 mm (1.0 in) in height on the scanner glass.
The document feeder still closes (the bottom of the document feeder is kept parallel to the scanner glass)
and allows the printer to operate.
The document feeder hinges provide height adjustment of25 mm (1.0 in) when a maximum downward force
of 4.5 kg (10 lb) is applied at the front edge of the assembly, with the fulcrum (such as the spine of a book)
centered on the scanner glass and parallel to its long axis.
The document feeder will withstand a downward force of at least 4.5 kg (10 lb) applied at the front edge
center of the assembly—when the fulcrum (such as the spine of a book) is located anywhere on the scanner
glass and parallel to its long axis—without breaking, deforming, detaching or experiencing performance
degradation.
The document feeder hinges support the assembly in the open position and prevent the document feeder
from suddenly closing in a damaging or loud manner.
The hinges can hold the document feeder static in all positions higher than 100 mm (3.93 in); measured at the
front of the assembly. Less than 2.3 kg (5 lb) of force is required to open or close the document feeder.
The hinges allow the document feeder to open to an angle of between 60º and 80º from the horizontal
position (this angle will not allow the printer to tip over).
