6-4-10. Special Service Mode Operations
When the IMAGER is operating in service mode (SERVICE SWITCH actuated), the MCS always sees the
FRONT DOOR as being closed. Be familiar with the following operations for controlling film CARTRIDGE
functions when in service mode:
•
To close the film CARTRIDGE and open the FRONT DOOR: Use the LOCAL PANEL
Open Door
key.
The CARTRIDGE will close, the ELEVATOR will rise and the FRONT DOOR will open, as normal. But
the LOCAL PANEL will indicate “20-208 Door Open Fail”. (The FRONT DOOR still appears closed in
service mode.)
•
To lower the ELEVATOR and open the film CARTRIDGE: Set the SERVICE SWITCH to normal
mode. The MCS will see the FRONT DOOR as being open. Set the SERVICE SWITCH back at
service mode. The MCS will see the FRONT DOOR as closed, and will lower the ELEVATOR and
open the CARTRIDGE. The IMAGER will now be prepared to transport film.

AIQC and GSM
The AIQC (Automatic Image Quality Control) system and GSM (Gray Scale Manager) software work
together to provide image quality control.
6-5-1.
Purpose of AIQC
AIQC includes the entire subsystem of OPTICS, DENSITOMETER, PROCESSOR, RF TAG READER,
and LUTs (Lookup Tables) that ensures consistent density from image to image. To provide consistency in
density on printed film, AIQC must take into account:
•
Film characteristics
•
Variations in OPTICS MODULES
•
Feedback from the DENSITOMETER, which monitors density
To achieve its goal, AIQC generates Film Models. The functions of these is to map image digital vales to
the required film densities. AIQC determines when film calibration must occur, and then processes the
density step wedges on the calibration film to create the Film Models.
6-5-2.
Purpose of GSM
GSM is the software that receives information from the DENSITOMETER, OPTICS, and RF TAG
READER, creates the LUTs, and defines the ATTENUATOR setting for the OPTICS. Software
components of GSM are shown in Figure 6-26.
