TROUBLE SHOOTING
5-6-6. Cleaning the Dev Rack and DEV Tank with a System Cleaner
Scrubbing the rack rollers with cold or warm water will not completely remove the
crystallized processing solutions or built-up gelatin and silver solving out from the film. It is
necessary to wash both the DEV rack and tank with a system cleaner(option) every three
months.
(1) Remove the top cover.
(2) Install a splash guard.
(3) Open the DEV drainage valve. After the DEV tank is emptied, close the valve.
(4) Use a beaker to fill the tank with water.
(5) Press the [RUN] SW and let the processor operate for about 5 minutes.
Note
Processing chemical may be supplied into the processing tank depending on the timing of the [RUN]
SW being pressed. This will not adversary affect the performance of the system cleaner.
(6) Open the DEV drainage valve. After the DEV tank is emptied, close the valve.
(7) Fill the tank with a diluted system cleaner.
Press the RUN button and let the processor operate for about 30 minutes.
- Dilute the system cleaner at the rate of Cleaner(conc.) : Water = 1:7
- Because the cleaner is strongly acidic, neutralize the exhausted solution using alkaline
such as sodium hydrate, etc. when disposing of.
Note: Follow the instructions written on the package for other notes.
(8) Open the DEV drainage valve. After the DEV tank is emptied, close the valve.
(9) Fill the tank with water. Press the [RUN] SW and let the processor operate for 5 minutes.
(10) Repeat step (8) through (9).
(11) Remove the DEV rack, and wash it in water.
(12) Open the DEV drainage valve. After the DEV tank is emptied, close the valve.
(13) Install the DEV rack.
(14) Install the splash guard.
(15) Fill the tank with a starting solution, and add a starter solution.
(16) Install the top cover.
Note
(1) Be careful not to splash the solution over the
film entrance sensor when you clean the
processing tank. Should the solution contact
with the film entrance sensor, thoroughly wipe
it out.
(2) Install the splash guard in order to protect from
splash. Hook the splash guard on the rib
locating at the upper part of the film entrance
slit as shown in the illustration below. If the
chemical solution adheres to the surface of the
film sensor or splash guard, wipe and clean it.
