Default Brother MFC 9420CN Color Laser Printer

I'm trying to repair this multifunction color laser printer / copier /
fax / scanner. The person who gave it to me indicated it needed a new
OPC belt. Sure enough, when powered up it gives a message "No OPC
Belt. Install OPC Belt" Unusual, the normal message is "Replace OPC
belt". Once I found out how to replace the OPC belt, I discovered the
belt was already present. And I discovered the tension release pins
on the belt cartridge were still inserted (they are to be removed
before installing the cartridge).

Since a new belt costs in excess of $200, I would prefer to establish
the cause of the error message before spending that much money. There
are no obvious pressure or optical switches to detect the presence of
the OPC belt. Does anyone have any experience servicing these?
