I don't think you can do that, anyway. =^..^=

Re: Konica c650 Scanning Issue.

**Okay Update**

It was the mirror. After several hours of trial and error, me and my two fellow *ahem* geniuses were running out of options. And I mean we tried just about everything.

After some hours, the options were becoming increasingly unattractive, such as, CCD replacement and board replacements.

So in a paroxysm of frustration, I grabbed each mirror and put quite a bit of pressure on them in a controlled jiggle fashion. Finally, the mirror in question snapped (quite loudly) into place and there was a moment of disbelief and joy--we realized that something profound just happened.

Well everything was fixed, sans a very small yellow spot in the same corner.
There was some merriment and the day concluded.

The sad part of this story....I tried several methods for curing the leftover yellow spot, and concluded that the bottom mirror was still slightly skewed or even flawed in some way. So as I was working on something else, my young coworker unbound the scanner drive cable and created a REAL mess. As a result, the plastic shielding was breached on a few spots, and I fear I will have to replace the entire "scanner drive cable" (perhaps, I might be able to remove the shielding and use grease...but there are some minor kinks too).

You guys helped out a lot!

Now, maybe someone will help out and sell me a scanner drive cable for cheap.....lol

Oh, the horror! Back in the 90's when scanner cable replacement was considered normal maintenance, it didn't take long to learn that scanner wire ropes were best left unmolested whenever possible. I'm sure you don't have the factory jigs to help you hold the cable as it is installed, but you can use such low tech aids as black tape, and 14 gauge copper wire to hold the loops of cable in place while guiding it to it's final path. If possible, I would find another of it's breed and snap a dozen photos of each loop, pulley, and eventually the pinch bracket, and final hook. This way you can be sure you're doing it right. Even in the day, there were never really good instructions. The best that you can hope for is a good routing diagram.

Congratulations on you're **success**. =^..^=

I love low tech aids!
That is a good idea with 14 gauge copper wire and black tape--I have been using scotch tape and rubber bands--lol.

This is a total pain in the arse though! I have had it almost together something like 8 times, but something always screws it up at the very end

However, the service manual is fairly straight forward, and the cable paths are quite simple on this machine (once once one clears his/her head and approaches it without emotion).

Another thing I might try because this is so finicky in the final process is go buy some very large plastic/neoprene washers and install them next to the winding rollers--the rollers that you have to wind the cable around 10 times in two directions.
If there is any slop in the cable it will unravel and promptly come off the roller. If I can at least keep the cable on the roller I can take a flathead screwdriver or whatever and align the cables so that they are not crossed after making adjustments. Afterward the washers can be cut off or left on (depending on if they get in the way)

I will take some picts of this if it works.

Thanks for the reply blackcat!

Re: Konica c650 Scanning Issue.

I will look into the settings for focus when I get in front of the machine again. And I love your sense of humor and story =)

..one of the mirrors is out of the place.....
..in A4 the copy and scan is good ?

You are correct, one of the mirror was out of place. Thanks for the response.
(Maybe you replied before reading the second page though? This issue as been resolved.)

Also, to update this entire post: I installed the cables, but have yet to put all the other components back on the machine. Keeping my fingers crossed until tomorrow.
