I can't calibrate the colors of my HP laserjet 251nw, the colors are shifted about 3 mm lower than the baseline, while the black color is in place: I tried with original toners, I tried with non-original toners, I have tried to update the drivers, I tried to update the firmware, I tried to reset the printer, I tried to follow all the instructions in the manual. I have not found a solution. How can I solve the problem? How can I calibrate the colors? Can they be calibrated manually?

Make sure firmware is up to date, perform a factory reset and then perform 3 full calibrations.
