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. =^..^=

I don't think this is my case..
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'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.

Re: Samsung CLX-6260FW printer prints blank pages.. most of the time

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?

Well, it is personal now between me and this printer, economy is irrelevant :-)

I don't think toners are the problem.. printer was working fine for years, and it started to misbehave after half of black toner in installed cartridges is spent.. and I tried with new cartridges, the intermittent behavior is the same.

The problem here is insufficient documentation, and imposed attitude by Samsung (and many other manufacturers/products): "easy repair - just replace modules, if it doesn't work just throw away, it's not worth the effort".
This philosophy doesn't work for me.
And, if I solve this problem, my effort could potentially help someone else.. so my time and effort will not be wasted (I hope).

If you are using non-genuine toners, I would highly suggest to replace with genuine toners. Irrelevant if it was working 50 years with no problem on said toner brand.


Most manufacturers have very large amounts of documentation, but this is not publicly available or is available only to a limited extent, apart from when people upload it to maunal sites where you can then get access to some of this. What tends to happen is techs only read a fraction as that is what they believe is relevant to the specific issue they have.

Hi. I don,t know if you have fixed this fault but you will find it is the actuator solinoid sticking, its the rubber perished. you will find it on the main drive unit.

No, I am still investigating.
Can you tell me exactly where this actuator is? In the past I had #A1-4112 Error, and I fixed this by inserting new cushion.. and error is no more. Are you suggesting this may be the problem again?
Thanks,
