WARNING -
THE UPPER COVER DOES NOT LOCK and should be held with one hand at all times while a free hand
is used to adjust the document pressure setting
.
To avoid personal injury it is not recommended to leave the cover of
SmartLF unattended in the open position. To close the cover, lower it forward to the horizontal then push it down
gently with two hands until it stops.
13. THE SMARTLF VARIABLE PAPER HOLD DOWN (VPHD) SYSTEM
Open the SmartLF cover (see earlier section). The upper cover opens in a similar manner to the main scanner lid
revealing the VPHD adjustment sliders.
The VPHD has two connected tabs that slide left and right to adjust the pressure placed on the document during
scanning. Contact image sensor scanner devices like SmartLF achieve higher performance when the document is
maintained in close contact with the scanner glass. Folded documents may cause shadowing when scanned in
greyscale or colour. SmartLF VPHD is used to minimise the effect of folds in scanned documents.
Moving the slider to the right (
>
) reduces the pressure to its lowest setting. In this position SmartLF can scan
lightweight and low stiffness papers like newspapers. NOTE – Use the lowest pressure position to scan small size
shiny surfaced documents.
Moving the slider to the left (
<
) increases the pressure to its highest setting. By moving the slider to the left, the VPHD
can apply pressure to folded documents to reduce the depth of the folds or remove them completely from the scanned
image. WARNING – Using too much pressure on a low stiffness document may cause media buckling or cause
smaller documents to skew in the scanning mechanism.
The VPHD slider is continuously adjustable (
<>
) between high and low pressure and may be used anywhere in the
range to suit the stiffness and fold density of the document being scanned.
NOTE - VPHD PRESUURE IS EVEN ACROSS THE WHOLE
SCAN WIDTH. BOTH SLIDER TABS ARE CONNECTED
INTERNALLY TO PROVIDE A SINGLE DOCUMENT
PRESSURE ADJUSTMENT. THE LEVERS DO NOT PROVIDE
SEPARATE ADJUSTMENT FOR EACH SIDE OF THE
SCANNING AREA
SMARTLF HAS INTELLIGENT FILE OVERWRITE/ RENAMING
If a file already exists inside the computer directory with the
same name as the name the operator is about to use for a
new scan, SmartLF will try to assist.
-
If the file does not contain numerical information SmartLF
pre-selects (blocks) the name part of the file ready for the
operator to type in a new name.
-
If the file contains numerical information SmartLF pre-
selects ONLY the numerical part ready for the operator to
type in a new number.
