The following printing problems also can prevent the reader
sorters from identifying a MICR character.

Dry ink slivers

Dry ink slivers are caused by a sharp point or edge gouging the
characters. This gouging could occur at a number of different
places within a reader sorter.

Damaged or ragged characters

Damaged or ragged characters may prevent the reader sorter
from identifying a MICR character. If the damage is random and
infrequent, it may be due to a paper grain defect. Consistently
ragged characters may be caused by a failed dry ink cartridge, or
the need for machine service.
Character damage may also occur if the paper is sharply
creased or folded before printing or during reader sorter
processing.

Crayoning

Crayoning results when material collects on a write or read head
and is redeposited on a following document. Frequent
occurrence may indicate a defective reader sorter pressure
brush. Other possible causes include out-of-adjustment print
density, fusing, or a poor choice of paper.
The performance of any mechanical device, whether a high-
speed reader sorter or a Xerox printing system, depends on how
well it is set up and maintained. Refer to the reference manual
for your product to find out how to avoid possible problems.
