Small Optical Comparator
The Small Optical Comparator also compares the MICR printing
to industry standards (see the following figure). Its main
difference from the MICR Gauge is that the Comparator’s
nominal 8x to 12x magnification and built-in measuring scales
enable you to measure printing characteristics that require
greater precision.
Figure 6-2. Small Optical Comparator
Magnetic testing equipment
Each MICR symbol and character has an ideal waveform and
nominal signal strength. Every MICR printing technology
modifies the waveform from the ideal in a different way, so that
the nominal MICR signal varies somewhat among the characters
and symbols. These are characteristics of the printing
technology and font design, and cannot be adjusted in Xerox
MICR printers. For this reason, the signal strength of the On-Us
symbol is used as the Xerox reference for the entire MICR line.
