MICR OPERATING PROCEDURES
piece of thick, hard plastic. The Gauge is used by slipping the
document to be evaluated between the two pieces of plastic.
8 Power (X) Comparator with MICR Grid
Like the MICR Position and Dimension Gauge, the 8 Power (X)
Comparator with MICR Grid also allows you to compare the
MICR characters to industry standards.
The comparator is an optical tool which magnifies the character
eight times. It has a built-in measuring scale to measure the size
of the MICR characters and to check for spots and voids.
The comparator can be used by transmitted light or by reflected
light.
Transmitted light Hold the document in front of a transmitted light source, with
the bottom of the comparator on the document. This allows the
light to be transmitted through the document. This is especially
useful when looking for voids (deletions) and checking character
edges.
While transmitted light leads to the most accurate viewing of
character quality, transmitted light tends to narrow lines and
make spots appear smaller. Also, the comparator's grid
dimensions refer to viewing by reflected light.
Reflected light Hold the document in front of a reflected light source, with the
bottom of the comparator on the document. Reflected light is
the best way to check spots.
Notes:
1. Patterned paper may cause viewing problems. It is a good
idea, therefore, to use white paper for quality evaluations.
2. MICR quality may vary with the type of paper used.
3. Handle the comparator with care. The grid is printed on the
bottom and may be damaged or worn off in time.
Adding dry ink
The procedure for adding dry ink is identical to the procedure on
the non-MICR printer.
CAUTION: Use only MICR dry ink for a MICR (4635/MX) printer.
MICR dry ink cannot be re-used or interchanged with the
standard, 4135 or 4635 dry ink.
