Paper facts • To achieve reconciliation without substantial waste, always use the stock sheets in the same order-lowest to highest- so that the sequence remains intact. • Avoid gaps in the sequence. • Storing unused stock without wrapping may cause runability problems the next time it is used. • The numbering order depends on how the paper is loaded in the feeder tray. If the paper is loaded face up, the lowest numbers must be at the top of the stack. If the paper is loaded face down, the lowest numbers must be at the bottom of the stack. For face down printing, either the paper must be boxed face down or the paper boxes must be inverted before the paper is used. • Synchronizing the sequential numbers with the check serial numbers is not recommended because of the complexity it adds to the production process. Operators are required to input the starting sequence number, and the job must be restarted any time a jam occurs. Features to avoid Some security features may either be ineffective or cause damage to the printer. Before making a major forms investment, always test new preprinted forms to verify that security claims are delivered without printer impact. • Some security papers contain chemical indicators that produce vivid dye images in areas where erasers, bleaches, or chemical eradicators have been applied. These indicators are intended for wet ink images and do not effectively protect dry ink images. They may degrade image quality, reduce document security, and severely impact printer reliability. • Another type of chemical treatment of the base stock attempts to reduce the risk of alteration through improved image performance. Some, but not all, of these treatments improve permanence. There remains a risk of printer contamination, with associated degradation in image quality, reduction in image permanence, and potential printer reliability impacts. 3-16 Generic MICR Fundamentals Guide
