Removal & Installation
16. Disconnect the large ribbon cable from the OMAS.
17. Remove the OMAS Sensor from the printer.
Installation
1. Verify that the two T-20 attachment screws are
correctly positioned in the Attachment Screw Retainer.
NOTE: To simplify the installation of the OMAS an Attachment Screw Retainer has been added to hold
the two T-20 attachment screws. This part is delivered attached to the replacement OMAS unit with the
two attachment screws. It is also delivered as a separate part with the Center Platen in case the OMAS is
completely removed during its replacement.
