UJV 160 Error 09 HDC POSCNT~~~PLEASE HELP!

[EffectiveCause]

I have a UJV-160 that has been having problems tracking its posistion while printing(see attached pic).

After cleaning the dust off the linear encoder strip and out of the sensor, as we have done before to make this problem go away, we got this "ERROR 09 HDC POSCNT". The Mimaki tech support said we needed to replace the linear encoder strip. Did that and still geting the same error. Any help would be appreciated.

maybe you just dislodged one of the cables going to the sensor when you cleaned it?

Yeah that was the first thing we checked.

 

[Kathi Hauser]

and you cleaned the sensor that reads the encoder strip?

loosing an equal distance with each pass?
Check the carriage belt and motor...
Sounds like its slipping.

the stepping is from encoder issues, which he/she knew.

after cleaning the strip and sensor, an error popped up

I'm sorry,
I have to say the obvious...it was mentioned the encoder was replaced and the cable for the sensor checked, but perhaps they overlooked cleaning the actual sensor.
But it sounds more like the latter I mentioned.

But that error is - ERROR 09 HDC POSCNT.
Replace the encoder PCB.

So if the display isnt switching between on and off when you move the head what does that mean?

 

[J Hill Designs]

sounds like it means your Y origin sensor is not working properly

One more question. So when performing the check encoder, the m number changes but the e number does not. Does this mean it could be the encoder is bad?

ok replaced the encoder and its working now. I can diffinitly tell the difference of how much sharper the image looks now with the new parts. Thanks for the help!
