Overview
The scorotron charges the PIP. There are three scorotron units that ensure a
homogenous PIP charge. These units are identified by the letters L, M, and R
(representing Left, Middle, and Right). All three units are interchangeable and maintained
in the same way. The scorotron units are mounted into the scorotron bridge, which
engages them to the PIP drum during printing. During PIP maintenance procedures, lift
the bridge to access the PIP.

Maintaining the scorotron
To remove the scorotron, open the front door, press the scorotron latch, and pull the
scorotron out.
To replace the scorotron unit, push the scorotron in until it clicks into place. The system
does not send any message to notify if the scorotron is not inserted completely, but it does
send the following error message:
