Scan-width
Scan Width is also set from WIDEimage. Use the units of the ruler
printed near the original’s insertion slot on the CHROMA Scanner to
determine the value.
The user can select through WIDEimage the preferable insertion
method for the original. Either side aligned loading or centered loading
can be selected. The ruler above the insertion slot is used with side
aligned insertion (at the ruler’s zero mark), and below the slot are the
standard size markings used with centered insertion.
The following table shows the number of pixels (RGB triplets) per line
resulting from various combinations of resolution and scan-width
settings in scan units on the side aligned insertion (top) ruler:
