Problem solving Determining the problem source 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. 7-4 Generic MICR Fundamentals Guide
