The document finally arrives at a diverter plate, which sends it
into the pocket that the reader sorter program selects based on
the MICR line data. The pocket has a pair of metal springs that
press the document onto the stack that is in the pocket.
If the pocket is empty, the document may impact against the rails
at the bottom of the pockets with greater than normal velocity.
Short-grain documents are especially vulnerable to leading edge
damage from this impact, and layers of paper may separate a
small amount on each pass. After multiple passes, this can
cause lead edge fluff.
If a MICR document cannot be read or is badly damaged in
processing, it goes to a reject repair station. Here, it is read
again, using low speed optical and magnetic read stations and
operator intervention when these read stations fail to recognize
all the characters. A similar process is also used for return
processing of rejected items.
After the correct MICR line encoding is determined, a repair strip,
encoded with the information that the processing bank requires,
is added to the bottom. In effect, a new MICR clear band is
added and encoded below the original one.
