Remove the glass, and use the drive drum to move the scanner through it's full travel. It should move smoothly. Are the cables crossed over on the drive drum? It's a common mistake to grab the mirror units and pull the scanner this way and that. It's very easy jump a cable that way. =^..^=
If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

Most probably the scanner moved a bit out of optical limit switch and now processor can't find the right limit.
Removing glass is not easy, lots of screws are in the way... but it has to be done - unless there is other, non-invasive method of moving the motor (maybe there is something in Tech Mode?) .
Moved the scanner by hand, no effect.
What could go wrong here? Whatever I repair, another problem pops out at opposite side of the printer..
After sleeping over the issue, it occurred to me the problem may develop around limit scanner switch (opto-isolator) or associated cable/wire/connector.
Anybody have any experience with those cables/connectors? They seem reliable when not disturbed but they are not designed for too many disconnections/connections..
Is it low cost a4 color model?

I don't reply to private messages from end users.
I've worked on a lot of models of the Samsux brand, and frankly they have all been pieces of crap..glad the ex boss dropped the dealership..
cheap parts BUT not to buy.
lousy tech support
and warranty claims were most times they were denied.
complete headaches.
It seems I found the reason for "scanner locked" error message.
When dismantling the front panel, I damaged the connector on PCB (only 3 SMD solder pads are too weak support and the connector was pulled off the board).
This connector is for limit sensor of the scanner.
The saga continues...

sure hope you are keeping notes.. because I'm not.
Glued on LCD board with superglue and soldered (could have been done better but... connection is important here, not the looks).

Scanner is not "locked" any more.
The list of what has been done so far in attempts to fix printing blank pages most of the time:
1) New main board -> no change, printout OK sometimes
2) New LSU - no change, printout OK sometimes
I checked voltages on HVPS board, they appear to be present and OK. Also, paper seems to have toner deposited here and there, which suggests the printer is OK, but either laser doesn't work (on both modules?.. not likely) or there is some intermittent contact somewhere so image is not placed on drums.
Any suggestions from experience with this printer (CLX-6260FW)?
And.. after some time I tried to print again.. success. But one page only.
The next one is blank.
Could it be faulty cap somewhere.. like those two in SMPS? Or something is overheating?
