Question about Sharp SF 2020 Copier
Hallow , keys are like electronic switches which wear with time may be due to dirt inside or normal expiry. They need to cleaned or replaced with similar ones. Open the control panel and unscrew the keyboard. You will identify them by their indication with a ' k' for example key 6 is written 6k. You can use WD-40 solvent cleaner if it doesn't work, then use a solder iron to remove old ones and buy sample like on any electronic shop and replace. Happy new year.
