(b) If there is no replenishment, check for empty storage tanks, air in
the lines, or a leaky pump that sucks air. Clean the storage tanks and flush lines. The
developer and fix pump bellows have poppet valves and O-rings that can cause
problems if they are not seated properly or are dirty. Visually check that they are
functioning properly. Position the poppet valves so that their stems point against the
direction of the replenisher flow. See figure 1-26.
Figure 1-26. Replenishment pump(s).
(c) Check the replenishment rates. If the pump is not delivering
enough replenisher, check the hoses and connections for air leaks. Make sure the
connections are airtight. Increase the pump volume by adjusting the stroke on the
pump to bleed the lines. If the pump seals are not sealing even when wetted, replace
(d) Check amp draw. Power to the pump is supplied through relay K1,
fuse F2, and terminal strips ATS1 and TS6. Check for line voltage between ATS1-1
and TS6-10 while depressing the film switch.
(e) Check and clean the level probes in the developer tank.
