DI850 slow to warm up

[sunsetoutpost]

This 850 ran fine until a day ago, now display says warming up. Can the fixing temp sensors be displayed? What temp does the fixer normally operate at?

The temp can be displayed in service mode. The temp should be around 190-200 degrees Celsius

I don't see the fixer temp sensors in the book. Where do I find?

Try printing management lists.They should show fusing temp..You can also adjust temp. in the 25 mode.

Still could not find in either management list or any other list. Did find the warm up problem. Bad connector #4027-1434-01 that feeds the fixer heaters is burned. Anyone had the pleasure of cleaning or replacing this connector. No disassembly instructions in the book, I'll just have to follow my nose.

If that is the same as Konica 7085, it will not give a code when one of the fusing lamps burns out. You may be running on 1 or none.

I have a BH920 doing the same thing! I looked at the lamps and all seem to work but have got spares to take with me again tomorrow. We have had problems with thermistors on these as well.

Took out the wire harness feeding the lamps. Some previous tech must have bent the tab on the fuser and slammed it into the connector. The shutters covering the connector and mounting bracket were bent. I don't think the connectors were mating completely and were arcing. This could explain why it worked some of the time. I'll find out in the morning after I clean up the contacts and reassemble.
