Durst multigraph error message

[Roger Thoms]

I'm getting a Lo op er5 message on my Durst multigraph head. The lamp is working but the shutter doesn't open for focusing or exposure. Any idea's?

Try Jason's suggestion. I have had the same thing happen to me when it is set at grade 5.

Since last week, my Multigraph Power Source has been humming louder than it used to. I am hoping it doesn't mean anything horrible.

I tried changing the grades, high and low extremes and middle grades all to no avail. Any suggestions on were to have the head serviced?

Not to be an alarmist but apparently there are issues with one or more of the circuit boards in Multigraph heads. This according to Jens at Jensen Optical, who has my power source now repairing it. Finding replacements is difficult and $$$$$. So, if it does go out on you then give him a call. I don't have his # right at this moment but google Jenson Optical and it'll come up. He's in Oregon.

Thanks Steve, I am aware of him - I hope I will be OK for a while without needing anyone's services. I am taking a few days off work next week so I can print.

I have a few new in the box Durst transformers for the Multigraph if anyone needs a fresh one.

It's not the transformer that is humming; it's the Power Unit (the Control Panel plugs into it).
