When Using as a TWAIN Scanner
This section explains the relationship between resolution and scan size when us-
ing the machine as a 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 33.2 inch. Since this is the same
as an A0 original, both A0 × 2 and A0 originals can be scanned at the same max-
imum resolution of 652 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 below:
Important
❒ 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.
