clear password administrator

[zuckryyu]

hi, i have canon ir adv c5535,and want to change the smtp port, and i cant change due to restriction, but some used machine came with different password..if i clear the setting which is COPIER>FUNCTION>CLEAR>PWD-CLR,does it go back to default "7654321" ..?

Yes

thanks....but today as i check it seems like the button "ok" at service mode been grey out,and i cant do anything to change it,even cannot clear code,history,jam,anything..does it have anything to do with authorization?....cause this is used machine,i thought maybe the last tech lock this service mode...anything to advice??
