If the CI-5000 is not working properly it should be initialized again; this is done by exiting from the
ID3000 menu, turning the system off, then powering up again. Another way to reset the CI-5000 is
by pressing the manual RESET button located inside the Color Film Recorder Assembly output unit
mounted next to the Power Connector.
The manual reset can be used to expose the resident test image to verify that the CI-5000 is
functioning properly. When the RESET switch is pressed, the Reset Control Circuit operates a reset
signal that initializes the Microprocessor Control network and associated circuitry. The reset signal
from the RC network of the Reset Control Circuit is AC coupled allowing the switch to be pressed
for an extended period of time (approximately 30 seconds). In most cases, it releases quickly
resulting in a very short signal which causes the Microprocessor and associated circuitry to be ini-
tialized.
Once the RESET switch is held in (pressed) for an extended period (approximately 30 seconds) the
test image will be exposed, the filter wheel will move, and the LED on the front panel will start
blinking. Once the LED stops blinking (50 seconds) the image is exposed. Pull the film from the
camera back and wait 70 seconds for the film to develop. The test image consists of seven colored
horizontal bars going from red at the top, to white at the bottom. CI-5000 configurations are
described just above the test image.
