Q. Can one use a computerized scanning machine to check a Mezuzah?

A. On question 3736 we wrote, “Horav Shlomo Miller’s Shlit’a opinion is that in our days the Sefer Torah should undergo a computerized test to check if no letters are erased or missing, specially in an old Sefer, before bringing it to the shul.

On question 2002 regarding if one does have to check tefilin and mezuzot using a computer program as it is done in our times with a Sefer Torah. We wrote: “Horav Shlomo Miller’s Shlit’a opinion is that if they were checked properly when written, one is not obliged to check them again.

However, the Rov maintains, since occasionally even after being revised by authorized professional scribes, mistakes are still found, it is preferable to have them computer tested and inspected. (See Maayanei Shlomo O.H. 4).”

The above does not mean that a certified Sofer, should not also check the mezuza, as AI machines can also make mistakes.
