[Misc] Problem with magenta module [DC6060]

[jayc67]

Hello,

I have a problem with the magenta modul or another part but in connection with magenta.

I add an outline as attachment.

Thanks in advance for your help.
Sorry for my english.

I have PWS and edoc. Somebody know where i have to search?

Thanks

Try to interchange the Magenta ROS unit with that of the Cyan (or Yellow, or Black) and see if the problem changes with it. If you connect to the printer with the PWS does it declare a fault, if it does what number?

[jayc67]

I also try to interchange the ROS unit but i always have the same problem. The PWS declare fault : 9-625 VH/VM Fail M; 9-637 Radcs ktc limiter fail M. Could it be the 1st BTR problem?

Thanks

[kandod]

Have you followed the procedures in the RAPs for those faults? You can check if it is a 1st BTR related problem by interchanging the HVPS and the roll and everything else with those of another color.

I also try to change 1st and HVPS, it was the same problem. And the RAPs too! I know that in edoc there's a page with information about the waves in the color but i don't find it.

Do you mean IQ 47 Wrinkle RAP? It is fuser related and do not apply to your problem.

Try swaping ESV sensor with cyan ( swap the sensor and pwb together).

I try this too and it doesn't work

[jayc67]

No I think that it's IQ11b. The interval is 0.5mm so that's the ROS, but I interchange the ROS and it's the same problem.

Can you post magenta halftone?
Check in DC922 and see what value is TC? If should be more then 80 if it is low you might have poor bias connetction.
Try swapping magenta dev housing with yellow ( ESV sensor is on the same location) seal it with some duck tape and run again halftone to see will the problem move with dev housing.

What is your LD output for the magenta laser? If its too high that will give you vh/vm faults. A weak drum usually causes this.

The magenta drum have less than 100000 meters. DC933 indicate that LDS is 1020. What's VMS?
TC value is 149 so it's ok.

I will try to swap dev housing but the halftone is correct, that's curious!

[kalindd]

LD 1020 is high.
I assume that you have tried with new drum?
VMS– is drum charge at 60% density Y,M,C and 50% K

[jayc67]

Yes i tried with new drum and it doesn't change anything.

Yellow VMS is NG, how can i do to change it?

Thanks
