It never used to do that; is there some way to avoid having to enter it every time I go to use the printer? Is there some battery issue that I'm not aware of?</P> Thu, 03 Aug 2023 22:38:14 GMT 2324 2023-08-03T22:38:14Z https://community.usa.canon.com/t5/Office-Printers/MF4570dw-keeps-asking-for-date-and-time/m-p/430642#M19949 <P>If I turn off my MF4570dw printer for a day or so, it keeps asking me to input the date and time to get it to work.

With that said....the 4570 goes back to 2011. It is an old machine. It might be better to replace it as opposed to attempting to repair it.</P><P>Canon Customer Service should be able to tell if a battery or a capacitor is being used.</P> Fri, 04 Aug 2023 12:16:56 GMT https://community.usa.canon.com/t5/Office-Printers/MF4570dw-keeps-asking-for-date-and-time/m-p/430691#M19953 dexman335 2023-08-04T12:16:56Z
