I have a Sharp MFP, Model- AR-5623, But i need to know about Serial number details and manufacture date.?

The serial number has to be on the receiver if it was manufactured after 1968. I guess Sharps closed in 1881 so they are not required to have serial numbers. If you have a reproduction manufactured after 1968, it will have a serial number.

Respectfully, are you referring to a Sharp Multi Function Printer?

If so, you are in the Hunting category.

Suspect your question got posted to this category due to the fact there are rifles bearing the name Sharps.

....a semi-auto printer ?...sweet....what 'caliber' paper does it take ?
