8K Series ProPalette Repair Manual Troubleshooting and Diagnostics

Test Image Exposure Sequence

To verify system operation, ProPalette cycles through the sequence for printing a test
pattern when Test Image is selected from the LCD menus.
By removing the camera and looking through the camera mount, a technician or operator
can verify operation of the CRT (a grid appears on the CRT face) and the filter wheel
(normal rotation sequence).
If a loaded 35mm camera is attached to the ProPalette when the self test is initiated, the
shutter opens just prior to the RED exposure and closes at the end of the BLUE exposure.
There is no change to any frame count and the film must be moved via the keypad
controls. This allows camera functionality to be verified.

Monitor Mode

The monitor mode selection on the ProPalette LCD menus passes control of ProPalette to
its EEPROM. This item is intended only for low-level tests during manufacturing and
service and has no use in normal operation.
If monitor mode is accidentally selected, press the Reset button on the rear of the
ProPalette to restart the system and return to normal mode. For more information about
entering Monitor mode, see page 51.

Error Message Redisplay

Error messages produced by startup diagnostics are displayed on the ProPalette LCD
panel for a few seconds. To redisplay the most recent error, select Show Last Error from
the ProPalette LCD menus.
Errors are also stored in flash memory and can be viewed with a host-side utility. See
"Error Logging (ERRSTAT.EXE)" on page 99 for more information.
