12 Checks the right edge of the media for skew (misalignment). (The loading process fails if
the skew is greater than the allowed limits.)

Roll Media
When a rollĆfeed assembly is installed on the DesignJet 330 and 350C roll media can be used.
The rollĆfeed assembly consists of:
D A rollĆfeed frame
D A spindle
D Two media stops
D A builtĆin cutter
The rollĆfeed assembly is installed below the sheet media entry path, to allow the ease of
loading for sheet media. When roll media is loaded into the plotter, it is passed around a
diverter roll, which optimizes the infeed path to the plotter. Once a plot is completed, the
builtĆin cutter is manually slid across the paper to cut the plot from the roll.

Removing Static Charge from the Media
An antiĆstatic brush located under the entry platen prevents static charge from building up
on the media. A charge can cause the media to stick to itself and jam the plotter.
Gripping the Media
When you load the media, it is gripped by the pinchĆarms. There is no pinchĆarm sensor on
the DesignJet 230 and 250C but there is one on the DesignJet 330 and 350C.
PinchĆArm Sensor
The pinchĆarm sensor is a switch sensor that is attached to the spittoon. It detects the
position of the pinchĆarm lever. Linkage, attaching the lever to a cam, causes the cam to
release the switch as the pinchĆarms are raised. The pinchĆarm sensor is electrically
connected to the main PCA.
