Figure 27. Photostatic camera (POS 1)
(1) Each chemical used in the camera gives a different indication
when you must replace it. You replace the developer when it turns dark
brown, the fixer when it turns yellow, and the rinse when it is cloudy.
If any of the chemical tanks have dry, thick, brown residue, you drain
the chemical and soak and clean the tank. Follow the manufacturer's
instructions when draining old chemicals, cleaning the tanks, mixing new
chemicals, and refilling the tanks.
(2) Next you must check the copy lights to ensure each light
operates after turning on the master switch (figure 28). If any of the
bulbs do not light, you must replace them. To replace any of the copy
light bulbs, turn the camera off.
