Thanks Blackcat4866
The missing idler wheel push's on the lever in the 3rd picture, and keeps the paper tray in up position. The idler i believe is attached to whole feed unit. A project I don't want to attempt. Customer "says new machine on the way"...
With the missing the idler wheel, I believe it doesn't keep enough pressure on the lever and the cassette does fall after some copies/prints.
I removed the spring from the lever, the cassette raises and lowers as it should. No Jamming after this spring removal.
The first picture is a es 287c, also OKI rebadge. We had this one in office for "repair" trying to talk customer into just junking machine. The 2nd picture was the ES477 I was working on.
That confirmed the idler wheel was missing and I needed to make a work around.
