are you trained on it or an end user?

This isn't something the end user can deal with! You need a Service Call !!!

Already replaced the toner coil and tube, cleaned the waste toner sensor, checked the coil out in waste toner. everything is ok, but toner pump and hose are not yet checked. Any advise again? thanks.

Already have service and parts manual.

The waste toner coils are normally to blame, especially the lower one. If you have replaced them you should be able to see all the gears and the coil turning with the back covers open while everything is clean- if not the coil has broken off the shaft or the drive gear is broken. I put in a stronger spring in the waste toner agitator guide that leads to the coils for good measure - that keeps the toner from clumping up and prevent the problem reoccurring . Also check the sensors that they are all clear of toner as this will give you that error too. Make sure the waste toner drops freely to the waste bottle. Good luck SC 495 is legendary

Toner coil cleaning works on several days and when the problem occurs again we disable the waste toner sensor with SP codes. Toner Consumption counter turn off, and the message did not appear again. SC495 was solve when we try to run output check of toner supply and locked the stand.

If that machine is anything like the Pro 907 EX, there is a second waste toner bottle behind a cover underneath where the toner supply is. If you haven't checked that yet, if time permits you might want to see if that's the case for your machine.

That is not a second waste toner. It is the waste toner bottle bottle. The bottle below the development unit is the vacuum collection bottle. It should be replaced at 3 Meg. The air pump above it should be replaced at 2.5 Meg. The two of them work together to keep pressure from building up inside the development unit and causing toner hazing. It is exactly like the 907EX other than being 10 ppm faster.

Thanks!
I guess that is one reason why the Pro series are not just big LD360s. Guess I'll have to hit the manuals before I go back to them.
