Fujimoto Maintenance Guide
To preserve optimum print quality using Fujimoto processors, a regular maintenance schedule
should be implemented. Following is our suggested routine.
Daily Maintenance:
Turn the CP51 processor off. Slowly lift the second rack straight up if you own a CP51, or the
third rack if you own a CP31. Raise it until it is completely out of the solution. Tip one end higher
so the excess solution drips off the opposite end. When the dripping stops rinse the rack with
warm running water. Be sure to turn the main gear while rinsing. Turning the gear will allow you to
thoroughly rinse all the rollers.
Remove the subsequent racks and rinse as described above. Be very careful not to contaminate
one solution with the other. After rinsing all racks, wipe the processor down with a damp cloth.
If a Wash/Dry Module is in use, turn the water off. Remove the wash racks. If water was not
running for at least 10 minutes since the last print, rinse the racks in running water. Hang the
wash racks up to dry.
*Always turn off the water before removing the wash racks. This prevents the water level in the
wash tanks from increasing.
If a Stabilize/Dry Module is in use, carefully remove the racks and rinse as described above.
For the Wash/Dry Module and the Stabilize/Dry Module, remove the dryer rack and hang it up.
If you own floating lids for your processor, place them on the chemical baths now. Replace the
covers on all modules, then open the in-feed lid on the Main Body (this reduces condensation).
Rack Storage: If the processor is used daily, we recommend the racks for any chemical module
be allowed to soak in water overnight. This procedure allows a thorough rinsing.
Note: Never wash the entrance rack with water because damage to the circuit board could occur.
Simply wipe down the rollers with a cloth. Always keep the entrance rack dry.
Wipe up any dripped chemistry from the processor, table and floor using damp and/or dry paper
Check the chemical overflow containers and empty if needed.
If the chemistry in the replenisher uptake containers is exposed to air, you may wish to put the
chemistry in a container better suited to chemical storage. In this case, the replenisher containers
should be rinsed. Leave a small amount of water in the bottom of the replenisher container.
Reinsert the uptake tubes into the replenisher containers for the night.
Weekly Maintenance:
When the Fujimoto processor will not be in use for several days, such as over the weekend, the
following steps should be taken.
After completing the daily maintenance, drain all tanks. If the chemistry will be used again it is
best to store it in air-tight containers, with floating lids to minimize oxidation. Wash tanks should
be drained to prevent the formation of algae.
Fill the replenishment uptake bottles with water.
Lift the entrance rack off the gear and lay it on the right so it will not turn once power is restored.
Slip two sheets of 8 x 10 paper side-by-side into the entrance rack so the paper feed sensors will
trigger the replenishment system.
Fill all the chemical tanks with water, less than 50 degrees C, until water is coming out the
overflow hoses. Be sure there is plenty of room in the overflow containers.
Turn the machine on and allow it to run for 5 or 6 minutes. The purpose is to take up enough
water to flush out the replenishment system. This precaution prevents small amounts of chemistry
left in the system from crystallizing and damaging the unit.
Turn the unit off. Drain all the tanks. Put fresh water in the replenishment uptake bottles and
repeat the cleaning process outlined above.
Note: When storing the processor be sure the replenishment uptake lines are primed with water.
This step will prevent the check valves on the replenishment pumps from drying out.
Note: If a Stabilize/Dry module is in use, replace the stabilizer weekly regardless of use. Before
pouring fresh chemistry into the tank, remove the rack, wash it thoroughly and wash the racks.
Monthly Maintenance:
In addition to the maintenance described above the following steps should be taken at least once
a month:
Use a non-abrasive scrubbing pad to scrub all the transport rack rollers. Be sure the scrubbing
pad does not contain any soap. Dishwashing pads that are safe for use with Teflon pans are best.
Rinse racks and inspect them closely. Use a small tooth brush for hard to reach places. With use
it is normal for some or all the rollers to become discolored. As long as the rollers are kept clean,
this discoloration has no effect on performance.
After draining the chemistry and flushing the tanks and replenishment system one time, drain the
rinse water and scrub the tanks with the scrubbing pad. Pay special attention to the area around
the top of the tank where the chemistry meets the air. Use paper towels to mop up any loose
Refill the tanks and run for 5 or 10 minutes. Drain the unit again and clean the processor using
Processor Clean II. Complete directions are on the package.
Replace all filters. Use damp towels to wipe off the polished surfaces and paper guide on the infeed lid. Dry the unit completely.
Inspect and clean all parts of the processor that need attention. Be sure to check between
Inspect the dryer rack rollers and wipe down with a damp sponge if needed. Apply silicone grease
to the worm gears in the dryer module. This lubrication'will prevent the gears from drying out.
Pull the filter drawer out of the bottom of the dryer module and wash the filter under warm running
water. Pat the filter dry with clean paper towels and reinstall.
If the equipment is used heavily, you may want perform the monthly cleaning routine more often.
Attention to these procedures will prolong the life of the machine and keep service visits to a
