LAMP FAILED TO REACH TEMPERATURE
PRESS ENTER TO LOAD DEFAULT GAMMA TABLES
No
Yes
SUMMARY
DENSITOMETER LAMP failed to reach operational brightness with stable temperature. This is monitored
only during a film calibration cycle.
SEQUENCE OF EVENTS
•
IMAGER initiates a film calibration cycle.
•
DENSITOMETER LAMP is progressively ramped up in brightness.
•
Software monitors the A/D output of the PHOTO DETECTOR SENSOR.
•
If photo detector does not reach an expected minimum level, the error is set.
PHONE FIX -- OPERATOR CORRECTABLE
De-energize the IMAGER. Wait 5 seconds, then energize the IMAGER. The IMAGER will automatically
initiate a new film calibration cycle.
ON SITE --TECHNICIAN CORRECTABLE
Problem
-- DENSITOMETER PHOTO SENSOR DETECTOR did not detect expected increase in LAMP
intensity during its ramp up.
Solution
-- Clean DENSITOMETER SENSOR and LAMP with alcohol pads.
•
Check connections to CPU BOARD at P3.
•
Watch DENSITOMETER LAMP during calibration. If LAMP gets progressively brighter, but Debug
program does not show progressively increased readings (see TECH TIPS), change the CPU
BOARD.
•
The LAMP might not be bright enough for an aging SENSOR. If R55 on the CPU BOARD is not
7.32 K (7321) ohms, install a new BOARD.
•
Install a new DENSITOMETER ASSEMBLY.
TECH TIPS
Connect a terminal program to the SERIAL SERVICE PORT on the IMAGER, and use CTRL D to monitor
a calibration cycle using the debug program of the IMAGER. When current is increased, the output of the
A/D is indicated as digital values for the LAMP intensity. The digital values are displayed at 3 levels.
Normal values for a fully functional system are:
DL 2,
DL 35
DL 196
DH 44
DH 690
DH 3874
The exact numbers are not critical, but the progression from low-to-high levels within this range of values is
important.
