REPLACING THE PEN TIP
The pen tip (nib) will wear with normal use. Excessive pressure will cause the nib to wear sooner. A worn nib may damage the coating on the Cintiq display screen. To avoid this, periodic tip replacement is recommended.
When the nib gets too short or develops a sharp edge, replace it with one of the extra nibs that came with the pen.
To remove the old nib:
Clasp it with a Wacom nib removal tool, pair of tweezers,
To insert a new nib:
Slide it straight into the barrel of the pen. Firmly push the nib until it stops. The new nib will slide into the correct position.
WARNING Prevent children from swallowing the pen tip or side switch. The pen tip (nib)
or side switch may accidentally be pulled out if children are biting on them.
Important: When the pen is not in use, place it in the pen stand, the pen holder, or lay it flat on your desk. To maintain the sensitivity of your pen, do not store the tool in a container where it will rest on its tip or eraser.
