Enclosed Paper Roll
Most calculators (with the exception of
Monroe 7130, 7140, 7150, Classic, Pro and
8125) have the paper roll mounted externally.
display calculator is the printer. It is also
the component most likely to fail, as it is an
electro-mechanical mechanism. The most
common cause of printer failure is dust and dirt
collecting on the paper roll and falling into the
print mechanism as the paper is fed through
the printer. By enclosing the paper roll, Monroe
protects the paper roll and by extension the
life of the printer from this common cause of
printer failure. If the paper roll is external, it also
means paper roll holders (typically plastic) are
mounted externally to hold the paper roll. It is
almost certain these paper roll holders will be
lost or broken during the course of use. At the
very least, this design means the operator will
be forced to replace paper roll holders during
the life of the calculator, replace the calculator
or come up with some inventive method for
supporting the paper roll when the holders are
lost or broken.
Another drawback to mounting the paper roll
externally is the typically cluttered desk of
most users. If the paper roll is lodged against a
book, stack of papers or some other object on
the desk, it is likely the paper cannot advance
136
or move through the print mechanism. As most
touch operators do not look at the calculator
during addition columns, such an operator
would be both surprised and disappointed to
look at the tape after listing a long column of
rather than the answer. Again the enclosed
paper roll design eliminates this possibility.
The expected life of the print mechanism is 2
million lines of print. The enclosed paper roll
enhances the ability of the printer to reach its
expected life.
Print Quality
There are at least three factors affecting the
one of course is the ribbon. The other two
common factors are the paper (thickness)
and the manufacturing variance of the printer
(distance between the platen and print wheel).
Monroe carefully selects both ribbon and paper
greatly when obtained from sources other than
Monroe.
Size
The 8125 has been designed to provide the
smallest possible footprint while keeping the
paper roll enclosed.
Today's calculators are descended from
yesteryears mechanical adding machines. All
mechanical adding machines had all adding
the right of the numeric keypad. Recalling that
the most often used function of a calculator
is addition and subtraction, adding machine
