Have F1 in display - need to know what this means

[johnbla]

F1 ...what ?

...hold the 'Start' Button down and another set of numbers are displayed.

F1 generally refers to the Bin Sorter/Finisher [the S16 or S53]...

Check that nothing is jammed in the Sorter Trays that would stop them from moving when the machine starts up.

Going off memory from distant past.
Thats a very old box.
