4.4 Using the EV Document Hold-Down Unit

The EV document hold-down unit (the unit with silver handle-rings at the ends) should be
used with certain document types as explained below. The EV document hold-down unit
is usually mounted on the two stock brackets which are hooked onto the stand's center
bar (CS1000EV and CS1100EV model mounted on the optional stand). When you want
to use the EV unit, remove the standard document hold-down unit from the scanner, replace
it with the EV unit, and then store the standard unit on the stock brackets instead. If you
have a CS1100EV model without the optional stand, store the document hold-down unit that
is not in use in its original box.
Please use the EV document hold-down unit with the following document types:
• Plain paper with a thickness of 0.08 mm or higher
• Documents with creases or strongly curled documents where the creases or curl affect
the overall scanning quality
Do not use the EV document hold-down unit with paper less than 0.08 mm thick or
with limp documents, as the document may become damaged or jammed in the
scanner. The EV document hold-down unit has a stronger hold-down force than that
of the standard unit, and may cause damage to thin documents. Use the carrier sheet
when scanning film documents or similar. In addition, because the precision accuracy
also differs, a distance correction operation will need to be performed.
< Distance Correction Method >
Distance Correction is performed using the Scanning Master 21+ software. Select Adjust
Scanner from the Tools menu to correct the distance as appropriate for the type of document.
Replacing the Standard Document Hold-down Unit with the EV Unit
Remove the standard document hold-down unit from the scanner, and replace it with the
EV document hold-down unit. For details, please refer to Section 4.5, "Removing the
Document Hold-Down Unit" and Section 4.6, "Mounting the Document Hold-Down Unit" in
this manual.
The handle-rings at both ends of the EV Document hold-down unit are silver. The
handle-rings at both ends of the standard document hold-down unit are black. Take
care not to confuse the two units.
The document hold-down unit has a symmetrical shape, so it is physically possible
to mount it with its left and right sides reversed. Because the scanner's precision has
been adjusted before shipment from the factory, however, the document may jam if
the unit is mounted in reverse.
