While cleaning and installing new cartridges I found this part. I think that some errors in calibration are coming from RM2-7399-010CN HP SENSOR, but I haven't changed yet.
I can't figure out where it would fit. I had removed the paper tray and old cartridges.
Can anyone help me figure out where this part should go?
