Problem solving
Generic MICR Fundamentals Guide 7-15
• Where in the document do the rejects occur?
Determine if they appear consecutively, in groups, or
randomly:
– Is there a pattern to these rejects? For example, are they
the same character, the same field, or do they regularly
appear after a certain number of sheets?
– Does this pattern suggest that the dry ink cartridge may
be defective by repeating the cycle?
• Is there an obvious pattern to rejects related to character or
position?
Inspect to see if a certain character seems to be causing the
problem. Does a character fail often if it is in a particular
position in the document?
• How are blank, backwards, or upside down documents
indicated?
Find out if there is a special code for these items, or if they
are treated as other types of rejects. Are they completely
missing from the report, or do they appear garbled?
• Are all the documents accounted for?
At the end of a print run, the number of accepts plus the
number of rejects should equal the total number of
documents that were submitted. If they do not, ask the
following questions:
– Did some of the documents disappear or jam?
– Did the system add something?
– Did the operator reenter additional documents?
Test patterns: alternative to reader sorter testing
Reader sorter testing requires the cooperation of the issuing
bank, and it addresses only problems with the bank’s processing
equipment. If appropriate reader sorters are not available, you
must rely on analysis of print samples to identify potential quality
issues and determine corrective actions for problem machines.
