MAINTENANCE
If the ID of the Transfer Roll is contaminated with ink,
the entire Transfer Roll can be submerged in solvent.
A cotton swab may also be useful in cleaning hard to
reach areas.
FIGURE 35
The frequency of required cleaning can be greatly re-
duced if the inking system is kept in proper adjustment
during normal operation and if the ink roll does not be-
come over saturated with ink.

CLEANING THE TRANSFER ROLL
The surface of the transfer roll is made from DuPont Delrin material and the O.D. of the roll is finely engraved
which enables it to hold a uniform film of ink. This surface material is very fragile and under no circumstances
should you attempt to clean it with anything abrasive.
Warning: Most of the ink solvents used for cleaning are flammable liquids. Follow all safety precau-
tions recommended by the manufacturer during this process.
To clean dust and ink residue from the surface of the
transfer roll, first remove it from the coder.
Lightly
saturate a soft cotton cloth with the appropriate ink
solvent and gently rub the surface of the roll until it is
clean.
Periodically, the inside of the Inking System Housing
should be inspected for ink residue and dust contami-
nation. To remove ink contamination from the sur-
face of the machine, moisten a soft cotton cloth with
the appropriate ink solvent and rub it across the con-
taminated area.
