Determining the problem source

7-4
You must identify the source of the problem before you can
implement corrective actions. For document quality problems,
you can best identify the cause by examining the rejected
document and determining the most likely reason for rejection.
However, rejected documents may not be available, or they may
not show any printer or application-related issues.

Reader sorter

If the problem resides with one of the processing banks,
verification requires the cooperation of the bank. Testing the
document in another reader sorter, preferably of the same make
and model, shows if a particular piece of equipment is at fault.
For amount encoding errors, different encoder ribbon batches
and part numbers can help to isolate the problem. You should
also investigate the effect of base paper stock and the
preprinting of forms.

Printer

If the printer is the cause of the rejection, you can verify this by
examining the rejected documents or MICR quality control
samples. Use the service documentation as your diagnostic tool
to conduct a thorough quality inspection using the methods and
tools described earlier. If a problem has been traced to the
printer, but no corrective measures can be identified, escalate
the problem to the next level.

Operator training

The operator often has the first opportunity to detect poor MICR
quality. Operators should be familiar with all aspects of printer
operation, paper loading, application features, job requirements,
and MICR quality control procedures. The operator should
identify and rectify problems such as image registration, gross
defects, and poor print quality before running a MICR job. If a
problem cannot be corrected, place a service call rather than
issuing MICR documents that are of questionable quality.
