TROUBLESHOOTING
SECTION 2.
AT2000 XR Film Quality Troubleshooting
This trouble shooting section is intended for the diagnosis issues relating to film processing
anomalies for the AT2000XR film processors. The itemized list below is a summary of issues, for
the complete diagnosis and/or repair of the issue exhibiting refer to the subsequent pages as
identified.
NOTE:
A major problem contributing to poor film processing quality is the contamination of the processor
chemistry. See AVOIDING CHEMISTRY CONTAMINATION provided on page 37 to prevent
problems.
