As the pen ink supply runs out, the
pen color will become lighter. This
indicates that the pen should be

Marking Systems:
Mark-A-Matic II Inking System
This type of pen consists of a self-contained ink reservoir
with a porous plastic stylus, which is snapped around the
outer edge of the metal pen arm.
A pen cap is provided to extend the life of the ink pen dur-
ing shipping or when the recording unit is not in service.
To remove the pen cap, gently lift the pen arm away from
the chart paper. Remove the black plastic pen cap to
expose the fiber tip of the ink pen and gently place the
pen back onto the chart paper. Do not let the pen arm
"snap" back onto the chart paper. This will flatten the fiber
tip of the pen and will no longer give you a fine line mark-
ing on the chart paper. Place the pen cap in a safe place
for future use.
If the stylus does not touch the chart, adjustment can be
made by slightly bending the metal pen arm in the center
towards the chart paper. Do not use more pressure than
is necessary to create a fine line marking on the chart
paper.
Replacement of Pen
Recorders Equipped with Fiber Tipped
Cartridge
The pen cartridge is securely fastened to the metal pen
arm using a special "U" clip tab.For ease of replacement,
it is suggested that the two screws that hold the pen arm
be loosened and the pen cartridge and metal pen arm to
be removed as an assembly. Refer to Figure 7 for the
location of the pen arm screws. Unsnap the plastic "U"
clip tab of the pen cartridge from the metal pen arm,
remove and discard the old pen cartridge. Replace the
new cartridge by opening the hinge and snapping it
securely around the metal pen arm. Refer to Figure 5.
