2211 Error Message

[fcpcdoug]

My Noritsu 2211 gave me Error No. 902 Scanner change of light error today. And anything I scan is too dark to see...

Does anyone know what this means and how to repair short of calling a tech at $1000 an hour.

Although I havent operated a 2211 for many many years, the change of light source is usually caused by the bulb in the lamp house section.  Try changing this bulb.

Today I changed the bulb and the reflector and I am still getting Error No. 902. Scanner change of light

Now when I do a Daily Setup with Updating Light Source I get Error No.904 Light source is out of limits

Check that the setup filter is not damaged. It should have 2 parts to it. The first part is a glass filter, the second part is a tin plate with holes in it.

Check that the reflector you have fitted is the same part number as the old one, as there are 2 types, the other type is for the 2611 series which is slightly different optically.

New bulb, new reflector, set up filter OK. Still getting Errors No.902 and 904. I think I'm going to have to call the tech in. Wish me luck.

Dumb question here! I supose you've checked whether the set-up filter is actually swinging all the way across when you turn the knob to it's full travel or returning to the home position when fully retracted. Mechanically the paddle tends to "fall off the perch" after many years of use......

Are you using a genuine Noritsu bulb or something like a Phillips?

[fcpcdoug]

I've had to tighten the set up filter before so that was a very good thing to check. I think it is returning properly.

The brand of bulb I've been using for years is USHIO. This is the first errors I've ever had with this part of the machine.

The light source is out of limits error can sometimes be because the difference in the light change is too great to do in one go. This can happen if the old reflector was really badly worn.

What you can try to do is reduce the amount of light going to the scanner, may be fit the old bulb back in again, and try the daily setup again.

Failing that partially block the top of the diffuser, to effectively reduce the light.

Once it has accepted it (if it accepts it) you can put a new lamp in and try again.

Also check the dichroic filters are all sliding in and out smoothly, sometimes they become stiff to move so cause the problem.

And make sure the lamp is in the centre of the reflector.
