For configuration options I made the mistake of looking in the configuration area of the machine.
The above solution applies to working at the LCD Display of the machine or via a Remote session on the virtual LCD - under Fax (not the Web Admin interface ).
At the LCD panel click on Fax. Close the 'To' dialog if it pops up, then scroll down to find 'Show Additional Features'
Does the Workcentre 6515 have a fax complete print option as well?
The 8035 and 8045 are literally the same printer. They are just clocked to a different speed.
If the firmware starts with 100 you follow the old directions and go in as admin and set it in the fax defaults area.
If the firmware starts with 101 you log into the copier as admin, go into fax and scroll to the bottom and click Show additional features
Then find the confirmation report and change
Change it to always
Then select Customize > Set as default
There doesn not appear to be any option to set fax confirmation to always print. Only options of OFF or print if fax failed. I see a posted solution for the Altalink C8035 but those steps don't available on the C8045. We just installed a software upgrade but still don't have the option to turn on fax confirmation Always.
