xpe-09-4362 "ros 2 (y) exposure at maximum

Sorry if this has been asked somewhere else... I couldn't find it by fault description or code number...

I finished a print job and tried to do color maintenance. Passes Xerographic setup but then gets xpe-09-1100 fault - along with a xpe-09-4362 "ros 2 (y) exposure at maximum" igen4 fault... Never seen this before and I can't get past the cycle up convergence fault...

I had something scraping the PR belt and I replaced that after I found out that one of the grids was bowed and fixed it ... I've replaced MOB wires and all the dicors.

There are magenta patches on the IB and OB edges of PR belt - almost like it is trying to do the color maintenance TRC linerazation and then stopping before it puts down yellow

 

Check to see if the shutter to the yellow Ros is closed and blocking the light to the pr belt.
