Document feeder hinges
The document feeder hinges allow the assembly to be positioned vertically above the scanner glass to
accommodate the placement of books and other objects up to 40 mm (1.57 in) in height on the
scanner glass. The document feeder is still be able to close (the bottom of the ADF is kept parallel to the
scanner glass) and allow the product to operate.
The document feeder hinges provide height adjustment of at least 40 mm (1.57 in) in when a maximum
downward force of 5 kg (11 lb) is applied at front edge of the assembly, with the fulcrum (for example,
the spine of a book) centered in the scanner glass and parallel to its long axis.
The document feeder is able to withstand a downward force of at least 15 kg (33 lb) applied at the
front edge center of the assembly, when the fulcrum (such as the spine of a book) is oriented parallel to
the long axis of the scanner glass but located anywhere within the scan window, 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 shutting 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) 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 horizontal
(this angle will not allow the product tip over).
