Table-Top Processor Chemistry Conversion Procedure

This procedure applies to cleaning and restarting a table-top processor or to changing from one manufacturer's chemistry to another, or from one chemistry type to another.

Highlights

• Before shutdown, the control strip reference step should be within the allowed range and its value recorded
• Use Imagelink Developer Systems Cleaner or Imagelink Microclean to clean the developer tank
• Finally, adjust temperature or speed until within ±.02 of the recorded reference density

Before shutting down the processor

• Run the process control routine twice to confirm stability
• Without a sensitometer, monitor the LD and RD steps of the pre-exposed strip
• Check production work to rule out a control strip error

Conversion steps

1. Turn off the processor
2. Remove the racks
3. Drain the developer and fix tanks
4. Rinse both tanks with clean water before adding cleaner
5. Clean the developer tank and racks with Imagelink Developer Systems Cleaner or Imagelink Microclean
6. If a replenishment system is used, replace the developer and fix bottles with the new chemistry
7. Fill the tanks with the appropriate chemistry
8. Turn on the processor and bring it to operating temperature with agitation
9. Splice and process 5 customer control strips in the darkroom
10. Record the average reference step density
11. Adjust temperature or speed until within ±.02 of the recorded reference density
