Please help me Miseq stopped run with error.

[Min Jung Lee]

Hello, everyone.
I ran miseq and 3hours later had been stopped.
"Focus mirror sensor not found" error message.
But! Thumnail images are present 2 cycles.
Clusters is good by the thumnail images.
Error message is below.
"Focus mirror move sensor and/or sensor failed:
The FPGA reported and error while exacuting command "FOCMRRFOC"
error message."
Anyone had experience about this error? And what happend to next?

This is definitely a hardware related error that none of us can help you with. Please contact Illumina tech support. Include a screenshot of the error in your ticket.

Contact tech support just to be sure.

Probably an hardware issue. But make sure the instrument is not upgraded to MCS 2.6.0.4 . We used to have similar issues (but can't remember the exact message) a couple of months ago. Loss of focus occured during the run.

Since our instruments are downgraded to the previous version 2.5.x.x everything seems to work fine again.

Problem solved.

I supported illumina tech team.
But error message is poped up again.
So, I contact illumina engineer in Korea.
They checked our instrument about focus mirror part.
And they diagnosed focusing mirror's movements are vey bad, replcement mirror and motor.
Finally, I ran again same libray.
Results is very good Q30 is 94.5% and PF is 93.5%!!
Thank you for everyone.
