removing konica c352 lens assembly

[acsolutions]

Hello, is there a procedure for removing the lens assembly! I had to replace the image processor board and had to remove the lens assembly to be able remove the board, and I think I removed the wrong screws! There are three screw in a triangle that are on the edge of the frame and two screws that have springs that I also removed! after replacing the image processor I am getting a code (lamp detection) I forgot the code!!! and yes the lamps come on! when I set the lens assembly down with out tightening the screws it goes through the process without error! I made the mistake of removing screws with paint, I know how stupid!! I feel bad as it is! I think that the screws that I was supposed to remove were the two screws on both sides and the frame slips through the three mentioned screws! is there a procedure to get those realigned also? any help would be great!! Thanks!

They have a jig at the factory to set up the lens assembly. Without the jig you might never find the right position.

Years back we had a new tech assigned to clean the CCD optics on a Mita fax. He saved a lot of time by removing those four red painted screws and cleaning the face of the CCD. The resulting scans weren't very pretty though. They were completely black. I spent most of the next day moving around the CCD PWB (the slots were less than 5mm long) until a got a very faint light blurry patch in one corner. Once I determined which corner was getting close to it's proper position it was only 2 or 3 hours more before I got it back to the right spot, and secured, and painted. If there is a method, I never figured out what it was. =^..^=

can I take an assembly off another machine and place it on this machine, and how would I do that?

Thanks for the reply! On the service manual pages you sent on 6. OTHER you can see three screws on the outer edge that are painted and 2 screws with springs, well those are the screws I removed so I could get the image processor out! What do I need to do to get those repositioned! do I need a Jig or can I remove a whole lens assembly from another machine to correct this or should I just grab a whole scanner assembly to resolve this? Thanks again!

taking from another unit would do the same. I have used a ruler and measured a known working one and used the left side of machine and left edge of the assembly to get it close enough to use the correct marks to make it work.

I thought removing the whole scanning assembly not the lens assembly! But what your saying is an option!
