Hos to correct the Y homing position

Hi,
I have the A1 printer. The problem is, Y homing position seems to be off by few mm and in effect, the nozzle sometimes misses the scratching strip. Similarly, it moves only at the edge of the cleaning rubber.

The printer reported Z homing error, so I now place the elastic plate a few mm off. Now the scratching pad is no more missed and there are no more Z homing errors.

I would prefer, though, to correct the Y homing position, instead of shifting the elastic plate carefully each time. It would also correct the cleaning rubber position.

Can the Y homing position be easily corrected?
