Setting up the Océ 3000 Microfilm Scanner 51
Reduction ratio For standard drawing sizes, the reduction ratio value is
taken from the Drawing Size File. This parameter can be
altered manually when this value deviates from the
standard reduction factor. The reduction ratio may be set
in the range of 5.00 to 36.00.
Drawing width This is the width of the image on the microfilm, in
millimetres or inches, according to the setting in the
Drawing Size File. This parameter may only be altered
manually when
NON
-
STD
size has been selected.
Drawing length This is the length of the image on the microfilm, in
millimeters or inches, according to the setting in the
Drawing Size File. The drawing length may only be
altered manually when the
NON
-
STD
size has been
selected.
X and Y offsets This is the number of microns by which the image in the
microfilm on the card is known to be off the centre of the
film.
Note:
These windows are available in the Run-Time
Display.
Unless the image is grossly or deliberately offset from its
normal centralised position, it is better to use the Rescan
option rather than changing the position of the scan
window. If the scan window position does need to be
changed, you can alter the X and Y offset values. Both
offsets can be adjusted between - 5000 and + 5000.
Print size The print size is the size used for printing the scanned
image. When selecting the size of the original image on
the microfilm, the system automatically sets the print size
to the same size. You can select a print size other than the
drawing size if required. The size A4 or E can exist as
portrait.
