New paper is loaded on the
PAPER SUPPLY ROLL
. Paper is fed from the supply
roll, across the table surface to the
DRIVE ROLLER
. On the AccuJet 520 a
DANCER
BAR
is positioned across the width of the paper between the supply roll and
the AccuJet table (Figure 3-5). The dancer bar provides even tension across the
supply paper, resulting in more accurate plots.

The drive roller advances the paper during a page advance.
All AccuPlot plotters except the AP-100 and AP-300 include a
PINCH ROLLER
,
which holds the paper onto the drive roller during page advances. On the
AccuJet 520, individual
GRIPPERS
perform the same function. The pinch
roller/grippers must be in contact with the paper to avoid a misfeed.
Used paper is collected on the

Carriage and Pen Assembly
Carriage and Pen Assembly
The carriage, mounted on the beam, moves the pen assembly along the X-axis.
The AP-100 and AP-300 plotters use disposable pens. The AP-310/320 and
AP-350/360 use disposable cartridges. AccuJet 520 plotters use a long-life pen
assembly with a refillable ink reservoir. The AJ-520 inkjet assembly, which is
mounted on the same carriage as the pen assembly, holds the inkjet cartridge
used to draw annotation. The inkjet assembly rotates, which allows annotation
to be placed at any angle.
