WASHING FOUNTAIN
REASSEMBLY:
It is recommended to disassemble and clean the fountain at the end of the days of production.
1. Remove ink fountain from the machine and place on flat surfaces. Loosen doctor blade screws.
2. Use 5/32 Hex Wrench to remove cover screws. Remove cover.
3. Lift out ink roller. Remove gear, bushings and seals.
4. Inspect doctor blade assembly and "O" rings for need of replacement.
1. Wash in Type B Cleaner.
2. Wash in Type C Cleaner.
3. Rinse in water. Dry with paper towel.
1. Put seals, bushings and gears onto ink roller shaft. (Be certain that the gear side and non-gear side seal
are on the correct ends.
2. Place this assembly into the ink fountain. The flat surface of the bushings must be in the up position. The
pins on the seals must be in the bottom corner of the fountain. (This will position the notches in the seals in
the up and slightly back position. The doctor blade will sit in these notches when the cover is replaced).
3. Put the cover on. Use 5/32 Hex Wrench to tighten cover screws.
4. Put small amount of pressure on doctor blade screws.
The ink fountain is the heart of your printing machine. Use a regular cleaning schedule and keep the
fountain away from lint and dust. Extreme gear wear and bad printing can often be traced to a dirty fountain.
Inspect the doctor blade regularly and replace if excessive wear is apparent.
It is recommended that the ink fountain be returned to the factory for inspection and maintenance if
excessive wear or malfunction is apparent.

DIMPLES
FLATS
SET SCREWS
ATTENTION
FAILURE TO DO SO WILL CAUSE
DAMAGE TO THE SHAFT.
When re-assembling the ink fountain gear
to the fountain roller shaft the set screws
in the gear must be aligned with the
dimples in the shaft.
NOTE:
RIGHT & LEFT SEALS ARE DIFFERENT.
The right side is stamped G for gear side.
When placing the seals back on the ink roller, the
flat should face the back of the fountain at a
45° angle as shown in the above photo.
It is very important to have the flats in the
correct position for the doctor
blades to work properly.
