Patch sorter mode (optional)
The patch sorter mode is optionally available for the XINO
®
S700. It allows the
switch-over between rear and front (top) paper stacker during operation. This
enables further sorting functions:
•
the separation of patch code sheets for reuse.
•
the separation of parts of the stack located between patch code sheets.
•
the separation of sheets depending on the length of the document.
Functional principle
The scanner comes with a sensor for the recognition of patch codes, which is located
just behind the paper feed. Owing to the position of the sensor the patch code is
detected in good time. Hence, the patch code function can already be used to
actuate the imprinter.
The sensor detects the patch code by way of reflected infrared light. Depending on
the position and type of the sensor the patch code sheets have to meet the
requirements listed below.
Patch code position
The patch code must be positioned at least 5 mm, but no more than 30 mm away
from the upper edge of the sheet.
The patch code itself is 20 mm wide; the thick and thin bars have a width of 5 mm
and 2 mm respectively.

Colour and print of
patch code sheets
Seeing as the sensor operates based on reflected infrared light, a high contrast is
required between the paper colour and the imprinted patch code. Ideal is a matt black
on white background. Simple black-and-white photocopiers or laser printers on run-
of-the-mill copy paper provide acceptable results. Colour copiers and printers on the
other hand often produce a shiny printing result that is not suitable.
For printing patch code sheets neither glossy paper nor black ink with a glossy finish
should be used. If you hold a patch code sheet diagonally up against the light, the
black bars should not reflect the light or only slightly.
