After a year of not using my printer (new processor board, new laser unit, which did not help then), I tried again and it worked! .. for a while.. then I am back to the original problem.
Tried...
Hmmm..
Thanks for the tip, I will investigate.
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...
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...
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...
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.
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...
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...
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..
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...
This printer is falling apart..
Now I have another problem "Scanner is locked"
I must have done something wrong when assembling.. When I press "Stop" button, scanner moves to the right for ~5 cm...
I loaded 5V output of SMPS with 6 Ohms (0.83 A).. and this is the result, similar to the situation when the whole printer system is connected.

SMPS is definitely faulty, it is supposed to...
In the meantime, I stumbled on another problem - printer doesn't start, all that's happening are clicks from speaker every 3-4 seconds.
This happened before once or twice, but after couple of 10s...
Yes.. this appears to be the next step... Cable is high density 0.5mm pitch.. but I will have a look the other end first, in case something else is obvious.
I found seller in US (LSU is for U$$...
The board arrived, it is alive and I do have an error "toner not compatible".
I reset the machine and it seems it works...
But the original problem is still there.
Copy one page and that's it.
So...
Could you send me a link with main board schematic diagram? It would be useful if signals are marked, with time diagrams..
Yes...
Board is on its way, will be here tomorrow or after...
I tried and the service manual I found is pretty useless for low-level debugging.. no circuit schematics. Basically, it says "if blank page is printed, replace main board or LSU".
Anyway... we shall...
Yep.. however I inspected connector under the stereo microscope and it looked normal, all contact apparently behave as they should.
perhaps the fault is inside connector and invisible, so I hope new...
It must have been something else then.. There was a pop-up window notifying me my post waits for approval.
Thank you for your reply, I really appreciate your help here. I had no idea there are two very different revisions of the board (as you probably guessed, I am just an amateur-repairer ;) )
Yes, if...
Thank you so much for your help, I really appreciate it. This printer was given to me by a friend (it had a problem with actuator (#A1-4111) which I sorted last year) with set of toners so it makes...
Connector in question is for flat cable for LSU.. after moving cable in and out (just a bit) I can print one page... but not much more, that is why I think about charging a gate..
I was also...
Thank you for suggestion, I actually did that...
The result was the same as with moving connector (and printing one page only..)
My theory is some control gate is floating.. and my manipulation...
It seems most of the time printer will copy only one page after moving cable/connector, but not print from comp...
Would that indicate the Main board problem?
