develop ineo+5501 - now adjusting

[sim22]

fault started on friday, traced to cyan dev unit replaced unit + developer, setup ok . Fault returned today all units setup up ok, test patterns run from service mode but unable to get machine out of " now adjusting " have found that no yellow band is being generated on the transfer belt during initialization but all other colours are present. No errors are displayed only constant " now adjusting ".

Any suggestions ?

[ No errors are displayed only constant " now adjusting " ] --> try cleaning the humidity sensor machine.
