copier doesn't have this feature. mp 161 has it called rx mode auto switch time

SC 553 is a fuser error code, could be thermistor or thermal fuse or fuser lamp

It's in the USER TOOLS menu.

You probably won't find one new, the model is to old, used is your best bet.

press [user tolls/counter] and then before you press the system features press it and hold the [#] button and while you hold the [#] button press [OK] the copier will ask you do you want to return the setting to default or not.
This procedure you may make and for the fax setting and for the printer settings.
After this the machine will bring the settings to the default

1.Press [user tools/counter] key .
2.Press and hold it pressed [#] key.
3.While you hold down pressed the [#] key press [OK] than the copier will ask you do you like to return the settings to default or not.

Contacted machine lessor. Thanks.

Hi TUlsi The majority of fax machines will do this, I know as the ones i use in DHL are the same when i contacted the company Cannon they advised that it could not be disabled. Which give the solution, All faxes are different and you will only know how to disable it by contacting the manufactures support. I agree full it is anti enviromently friendly and a waste of ink
