4. Drive Mechanism
The tx motor [A] drives the ADF roller [B], R1 roller [C], and scanner roller [D].
Because the scanner roller turns a bit faster than the R1 roller, the document
is always under tension.
The scanning speed for each resolution mode is as follows.

The scanner can feed paper up to 257 mm (10.1") wide. However, the actual
scan width is 256 mm/B4 [10.1"] (China models), 210 mm/A4 [8.3"] (Asia
models) and 216 mm/Letter [8.5"] (USA models).
The maximum acceptable document page length can be adjusted to 0.6 m
(23.6"), 1.2 m (47.2"), or 14 m (46 ft). The default setting is 0.6 m.
