LPU unit cleaning function

I propose to add a separate function for cleaning the glass of the LPU unit, since it is the third time I encountered a situation that after cleaning the glass of the LPU unit, the printer cannot calibrate. If the unit is calibrated at the factory, then why calibrate it after cleaning the glass. It would be good that you do not use the “replace the LPU” function for cleaning, but the “clean the LPU” function after which the printer continues to work without calibration.
It seems to me that not only me faced such a problem.
