Ok here is what's going on. We have 2 Ricoh 906s with the same issue. Empty waste toner message. We've called Ricoh tech support and replaced what they had suggested: the bottle, sensors, wire harness and motor. No luck the machine will run about 600 copies then shows the message to empty it. If you wiggle the bottle the message goes way but then comes right back. We looked for a counter or timer setting-nothing. Any tech pubs or ideas would be appreciated.
