S2 scanner problems

[MPhoto]

Having problems with our s2 scanner. It seems like the scanning led isnt on and the error 6327 -scanner light source section temperature error. Most of out workload is digital so the scanner sits sometimes for a while without being used. We have been seeing weird errors from it for a week or so, sometimes the scanner thinks there is film in the carrier. We did run a scanner sensitivity check, which is attached. We are not sure how  to read it or where to go from here. Seems to us , that it is either the led light source is out or a board issue. The scanner sensitivity looks wacked to us, but again not sure what we are looking for

any help is greatly appreciated.

Also have noticed the base where the actual light comes out is bone cold

What is the rest of the error number?

From the screen shot the LED temperature is showing as 53.2 this is too hot, it should be 45.0.

The most likely cause is the cooling fans especially the ones next to the light source are either not operating or are clogged up with dust.

You can test the fans in output check.

The other possibility is it is not correctly reading the LED temperature. Check for bad connections on the wiring going to the LED light source.

the error we are getting is 6327-0002. We did take off the led light source and found underneath was packed with dust, on the unit and back into the fan we cleaned it. We also took apart the back of the scanner and seemed that the fans were not spinning properly either. The middle one  seemed to be making noise so we swapped it with a new fan. After cleaning the bottom, the main led did light up. and it seemed to coinside with the stopping of the little muffin fans in the scanner back. We were able to get a light source update thru and scanned a few rolls of film and then the same thing happened again. We had put the scanner all back together but we still think it has to do with the little fans

Any ideas? Thx

Go into ouput check, LED Light Source section and test the operation of the small cooling fans.

[Dave S]

The 6306 error is quite common on the S2 scanners, I wouldn't worry too much if it's only happening sometimes. Some scanners have been having this error for many years!

the led cooling fan tab? I press execute but I dont really hear anything. Would we have to have the led off to insure the fan is spinning?

Yes, you should hear them, they are quite noticeable when they are running.

They should operate in output check no matter if the LED is on or off.

Take the fans out and check they physically turn by hand. They may have failed.

where does the led thermosensor get the temp from?

are you talking about the fans on the back of the scanner? If so the top two seem to be turning on and off. If we unplug the power from the scanner they are on but turn off after about 20 seconds.

or were you taliking about the little fan that is underneath the light source?

thanx for your help and input

the cooling fan tab in the led light source makes no noise when we press execute. This is for fan underneath the light source?

The thermosensor is inside the light source.

I'm talking about the 2 small fans that are next to the light source. There is one on the left of the light source and one on the right of the light source.

If those small fans next to the light source are not working it will definitely overheat after a while.

Great thx, we only cleaned the left side fan , missed the right. We will do that now, we just got in for the day.

Strangely we did fire up the machine just to see if it would error out first thing, while still cold. We noticed the fans on back /top of the scanner turn on , but go off after about 10 seconds. We figure that must be related to the below dust/overheat. Do you think that is accurate?

The fans on the back are not meant to go off. There are 3 fans on the back of the S2 scanner that should run all the time there is power going to the scanner.

It could possibly be related if the whole scanner is getting too hot, but less likely to be the main cause of the light source overheating.

The 2 small fans next to the light source do 90% of the work of cooling the light source.

ok we cleaned the compartment under the led light source really well . Still getting the same issue.The machine is on and those 3 little fans are off.(top/back) Yesterday one was making noise so I swapped it with another fan and that is when the light source temporarily turned on . I know you said they were not connected , but it is quite a coincidence. i put the new fan it , all three spun for 20 minutes, things were working well , then errors again. Seems like you said, maybe the whole unit is overheating. Or maybe we should swap in a couple other fans, since its easy, to eliminate some sort of short in the fan(s). What do you think? Seems to us those fans should be on too.

do the little fans by the light source constantly spin also? When we trun on the fan in the output check, we are reaching under the unit through the gap and can not feel the little fan spinning

The little fans next to the light source come on and off to keep the light source temperature at a constant 45°C.

Have you taken the fans next to the light source out to check they spin by hand?

It maybe the 24V power supply is overheating/ giving a problem.

If there is no 24V the fans will stop.

The power supplies are in the lower section at the back, they may also be very dusty.

Yes we did spin the little fans, do the tiny little fans and the three from th back come off thesame 24 v power supply?  Those 3 fans just seem dead. Got to something to that

Thank you Dave

Yes all of them are powered by the same 24V power supply

what does the 24v  power supply look like? Is it a switching board? The Noritsu s2 manual doesnt even show it.

Is there a way to test to see if the 24v power supply is working.

Thx we did notice the the two boards on the back top by the fans . Yesterday all three of these lights were lit, today both center lights( both labeled 24 v ) are both now off.  is there a way to test the 24 volt power supply board? We used a circuit tester and did pick up power coming off the board. Sorry stumpted.
