Changing the Inverter Unit

for use with the 4-Tray Finisher

The inverter unit comes configured for the 5-tray 

finisher option.

If you have the 4-tray version of the finisher 

option, you must change the inverter unit before 

installing the finisher:

X

Inverter as supplied

Y

Inverter changed for use with 4-tray finisher.

Orientation:

Front

Back

1. Remove the two bottom caps:

a. Turn the inverter over,  then remove the 

screws securing the bottom caps on either 

side of the inverter.

b. Remove the end caps and store them 

along with the four screws in case you 

ever need to convert the unit back.

2. Turn the inverter around and remove the 

screws holding the metal brackets in place. 

Keep the screws and brackets handy: they 

are used to help secure the extension plate 

once it is repositioned.
