CUVAX MC 50 Ricoh

This is a Ricoh CUVAX MC 50 Private Information System digital handy copier.
I tried to use it for the first time in several years, but the battery seems to be at the end of its life and does not respond even when connected to the charger. The BATT/AC lamp does not light up.
Since I cannot confirm its operation, I will consider it junk. Therefore, I will not accept any complaints or returns, and I ask for your understanding.
Includes the main unit and an aftermarket AC adapter.
