Minolta D1152 oL Error

[dlpenney]

I have an oL error on my Minolta Di152 copier. It says the copier cover is left open (it is not) and to identify the closure failure location on the control panel. There is a flashing light to the left of the Bypass Tray Size Select button but my manual does not show this part of the control panel at all. How can I find out what the flashing light means?
