Platen Glass - Canon iR2020 Facsimile Manual

Platen Glass

You should use the platen glass when scanning bound originals (such as books
and magazines), heavy or lightweight originals, and transparencies. (See
"Document Sizes," on p. 1-32.)
NOTE
1
The machine automatically detects the size of the following originals: A3, A4, A4R, A5R,
A5, and A5R. If you place your original on the platen glass of the iR2016 model, the
machine cannot detect the originals size.

Sensor
IMPORTANT
This machine is equipped with an open/close sensor on the feeder/platen cover
(located in the circled area in the preceding illustration). When placing originals on
the platen glass, lift the feeder/platen cover high enough so that the open/close
sensor underneath is fully released. Otherwise, the machine may not correctly
detect the size of the originals. (Only the iR2020 model can detect the size of the
original placed on the platen glass.)
