I Removing a Pen
Facing the plotter so that the pen station is on your left, remove the pen by gently pulling it out to the right and
toward you along the notched section of the pen station.
I Using the rubber inserts for the pen caps
Your plotter is provided with eight rubber inserts for the pen caps. Each rubber insert is placed inside the pen
caps in the pen station to prevent the ink in the mounted pen from drying up. Be sure to use these rubber inserts
only when using high-speed ceramic pens, refillable ink pens, or disposable ink pens. Never use the inserts with
water-based fiber-tip pens.
When a rubber insert is placed inside a pen cap, the tip of the mounted pen will lightly touch the rubber insert,
thus better maintaining the pens' conditions than when rubber inserts are not used.
Especially when using refillable ink pens, disposable ink pens or high-speed ceramic pens, be sure to use
rubber inserts, otherwise the pen tips may dry up or drip in the caps.
Mounting the rubber inserts
Use the tweezers provided to hold the rubber insert as shown below, then place it inside a pen cap at the pen
station.
When the rubber insert is mounted, the pen tip will contact the rubber insert as shown below.
NOTE
• Whenever possible, try to consistently assign the same color pens to each Pen No. If you mount another
pen of a different color, the ink of the previous pen (which will still be on the rubber insert) will adhere to
the tip of the newly mounted pen and may cause plotting to initially be performed using a mixed color.
Also be sure to periodically wash the rubber inserts for the pen caps with water to clean off any residual
ink.
• If you will not use the plotter for a long time, be sure to remove the pens from the pen station and cap
them.
