BH-C-25, Calibrating after wake up

[Hansoon]

This BH-C-25 starts a long calibration cycle every time it starts up after sleep mode. Any idea please how to stop this? Is this a firmware issue?

Whats the life count?
Have you changed anything?

My first bet would be replace either the transfer belt or K iu, they tend to be the items that I have replaced in the past to fix this issue.

Only K7K, C0.5K so in total 7.5K only. But I just discovered that exactly in the middle of the TB is a brownish line of toner residue in the feeding direction. Just where the IDC sensor sits. Will look after this first.

Thanks
