About <Free>
If you frequently need to change the paper to be loaded, set to <Free>; this will reduce the number of steps required to change the setting each time. However, take note that this setting lets the machine perform printing even if there is mismatch between the paper type setting in the printer driver and the paper type actually loaded in the machine.
When the paper type setting in the printer driver is [Auto], the machine operates the same way as when the paper type is [Plain 1].
