SHARP ER1911 None of the buttons will work they just beep when pressed

Make sure the 0 button is returning after pressing, could be stuck.

I’m happy to help further over the phone at https://www.6ya.com/expert/pat_7f6b46a4565f904d

Dear user,
Please check the all control panel buttons are working, press one time all buttons, while pressing a beep sound will come, other wise some problem in that button. If not come the beep sound open the control panel and clean the PCB dust.

Disconnect the printing cable and check it also. May be machine totally hanghang. Then also does not work the copy and print

According to the directions: Press B - bottom left button,to go into Alarm Mode. Press D - upper right button - to activate the alarm and press again to activate the Chime, which shows on bottom left as a bell. To activate these press D. To DEACTIVATE them press D again. Press B 3 times to return to Time Telling Mode. It took a few tries, but D and B are the keys to stopping that annoying chime!

It is very difficult to find information on the Sharp ER-1911 now. I don't have error notes for this model. All I can suggest is an online manual such as here:
