When Using as a Network TWAIN Scanner
The maximum resolution available for scanning is determined by the original's
horizontal measurement (width). For example, the width of an A0
× 2 original is
841mm (33.2"). Since this is the same as an A0 original, both A0
× 2 and A0 orig-
inals can be scanned at the same maximum resolution of 600 dpi.
Originals of any vertical length can be scanned at up to 1200 dpi resolution.
The maximum available scanning resolution for each original size is shown be-
low:
Limitation
❒ Large originals require more memory. Increase available memory by closing
other applications before scanning large originals.
Reference
To specify the scanning area or resolution when using the machine as a net-
work TWAIN scanner, see TWAIN Driver Help.
