maintenance described next are for the specific
processor shown. If you work with a different make or
model of an automated processor, refer to that
manufacturer's operational manual for operating
Figure 1-45 shows the main external components
of the large automatic film processor. Figure 1-46
shows the internal components when the top cover is
opened from the processor. Figure 1-47 shows the
functions of the operators control panel.
The daily operational check of the large automatic
processor is performed as follows:
1. Plug the power supply cable into the power
2. Check the solutions. Most automatic processors
are equipped with a replenisher, which automatically
replenishes solutions when the power is turned on. An
automatic processor without an automatic replenisher
requires that you manually replenish the developer and
fixer solutions. Pour the solutions slowly to avoid
splashing. Direct the pouring stream to the center of the
tank away from the drain tubes.
3. Turn on the external water supply valve. This
valve is normally located close to and above the
automatic processor. If not equipped with external
water supply, change the water in wash water container
and refill with fresh water.
4. Activate the automatic processor by depressing
the power on switch. If equipped with an automatic
replenishing system, the internal oscillating pumps will
now cycle and fill the solution tanks to their proper
levels. When the low solution level lamp has gone out,
the solution heater will start and the transports will turn.
Do not process films at this time.
5. After 10 to 15 minutes, The ready lamp will
illuminate. This indicates that the proper processing
temperature has been reached.
6. Depress the run/standby switch to the run
position. Insert an 8-inch x 10-inch cleaning film into
the processor receiving tracks. The cleaning film cleans
the rollers of accumulated deposits, dirt, and debris. Use
a new cleaning film every week. After the cleaning film
exits the processor, depress the run/standby switch to
the standby position.
