Scanner Setup
Scanner positioning and proper system setup are extremely important for proper
SV Series operation. The following sections describe the most common setup
possibilities in detail. Some knowledge of SV Series operation is recommended
to best follow the steps. Please refer to Appendix A (SV Series Setup Hints -
Scanning Distance and Angle) for a basic description of SV Series operation and
scanner positioning and calibration.
Positioning is important to provide accurate analyses. The scan distance must
be set accurately to achieve the proper beam focus to detect printer flaws and
failures, such as a worn ribbon (matrix printing), low toner (laser printing), voids
(flexo printing), burned pixels (thermal printing). The scan angle is important to
accurately measure bar code and substrate reflectance values.
Setup is important to ensure proper interface to print mechanisms and host
computers.
