c-4512, c-4511 error codes on KM c6000L

[schlf]

Sending anything to Russia now is quite challenging I suppose.
However, are there procedures I need to do right after swapping the write unit like in i/o checkmode, and also if there is any way to check if the sensor is working. because it seems like motors are fine for both units i'm getting error codes.

I would use a microfiber cloth and non-ammonia glass cleaner. Alcohol is OK too.

You may check "Color Registration Auto Adjustment" for inconsistent values. =^..^=

Btw about write sensor initial position memory (that's not the same of course but in case that's matter evev a bit)
+00078 Y
+00021 M
+00053 C
+00081 K

Keep in mind that the black laser is unique, not the same as the color lasers. =^..^=

All 4 Write units are identical partnum A1DUR70U00.

No procedures are needed, just swap the units (and remember original position) and DO NOT write initial position memory. You can also use similar sensor from other parts for diagnostics (I guess).

Forgive me, but if you by any chance know what the approximate range of skew adj. I've tried to move it manually by simple rotating the motor but however didn't know where that range ends to calculate estimated values and yet blindly rotating the motor itself didn't work

One more thing, swapped M and Y units and ran the machine in both cases err 4512

A bit offtopic but... nowadays it would be interesting sending parts from USA to Russia

Yeah... That might be a problem LOL

Below the laser, there is a sensor and an actuator that moves by steel cable through a motor inside the laser. Compare the problematic laser with a good laser. If it is different, open the laser and manually position it to the desired point. I always get a positive result like this.

But only do this if it really is different and if you are sure the problem is in the laser.

4511 Laser Yellow
4512 Laser Magenta
4513 Laser Cyan
4514 Laser Black

If you have 4511 and 4512, I suppose you shouldn't invert yellow laser with magenta.


Compare or invert with cyan

tried exactly this but none of my attempts were successful, sometimes the actuator was way in a wrong position after i give it a try. Is there any way to disable color registration with dipsw, or anything like this to just rid of the error and see how terrible the skew in fact is?

Perhaps, but that would be pointless. It will cease to be a production quality printer. =^.^=
