I received an inquiry today about a Konica Minolta SRX-101A that was not filling the fixer tank. After some discussion with the doctor we determined that the developer tank did fill during the auto-fill but the fixer was still empty. This is unusual because during the auto-fill cycle of a Konica SRX-101A the fixer tank always fills itself first with the developer lagging behind. We determined that the chemical replenishment lines were not kinked which would restrict the flow of chemicals into the x-ray film processor. We suspect that the poppet valves in the fixer replenishment pump need to be replaced.
