I seem to be locked out of the printer. I tried the default 7654321 for both boxes, but it doesn't authenticate. I tried online through the printer web page, still won't work. I can not get past the Department ID or the PIN. Anyone know how to reset this? Thank you</P> Sat, 15 Jan 2022 14:57:24 GMT https://community.usa.canon.com/t5/Office-Printers/Image-Class-642-643-644CDW/m-p/360269#M15204 Nomadusa 2022-01-15T14:57:24Z https://community.usa.canon.com/t5/Office-Printers/Image-Class-642-643-644CDW/m-p/360321#M15207 <P>Greetings,</P><P>If you have locked yourself out of the printer's admin portal, you will need to contact Canon for reset assistance.&nbsp;</P> Sat, 15 Jan 2022 20:10:36 GMT https://community.usa.canon.com/t5/Office-Printers/Image-Class-642-643-644CDW/m-p/360321#M15207 shadowsports 2022-01-15T20:10:36Z
