Paper handling by reader sorters

Hopper jogger


Medium speed: Process 1,000 to 1,500 documents per minute.
These machines usually use waveform recognition, frequently
with dual or hybrid read.
High speed: Process 2,000 or more documents per minute.
These machines are typically found in larger banks,
clearinghouses, processing centers, etc. They generally use
matrix or dual read technology.
Reader sorters are designed to handle batches of check
documents of mixed sizes, weights, and conditions (pieces torn
away, creased, etc.), at high speed. This may result in reader
sorters handling documents somewhat roughly.
Documents may undergo from 10 to 20 separate passes through
reader sorters. If the leading edge of a check is damaged slightly
in one of these passes, repeated sorting can increase the
damage until the document no longer feeds properly. Because of
the high cost of handling misfeeds, check processors limit the
types of paper that can be used to print MICR documents.
Reader sorters typically use the following mechanisms to handle
MICR documents.
The hopper jogger is usually least stressful to documents. It
vibrates the documents to aid in aligning and separating them.
A picker belt forces the first document forward, while a restraint
system retards the remainder of the documents. The initial
shearing force and acceleration applied to the document is
generally followed by a deceleration as the document is fed into
a multiple-document detection station.
If the forces are too extreme, or the document is too weak, the
document could collapse, causing wrinkles. Wrinkles normally
appear in the Amount field.
