Verifying problem resolution

7-16
All Xerox MICR printers incorporate MICR diagnostic test
patterns. These forms combine the needs of service diagnosis
and call closeout with MICR problem analysis and escalation.
You may want to use separate test pattern files to verify
individual PostScript, PCL, and LCDS fonts. The MICR line on
these forms is in the correct format for reader sorter testing. On
the test pattern that is accessed through diagnostics, additional
image elements are incorporated to provide insight into potential
MICR problems. All of the MICR quality control and diagnostic
procedures described in this guide can be performed on these
documents.
The use of these test patterns with advanced MICR test
equipment permits very sophisticated analyses, validating all
magnetic waveform characteristics against established
expectations. Problem escalation should always include these
print samples, to facilitate quick identification of problems.
Unlike print quality or paper handling problems, MICR quality
problems require some vigilance, even after the source has been
identified and the problem resolved to the satisfaction of the
customers and their bank. Bank reconciliation processes and
check cashing policies may require a month or more for the full
benefit of corrective actions to be seen. In the case of blank
check books, the old stock may take years to deplete. Depending
on the severity of the problem, you may need to take a proactive
approach to ensure that MICR performance issues have been
resolved.
