Insert a new cartridge.
Insert a new ink/dummy cartridge and gently slide the cartridge into
the pen. Carefully tap the cartridge tip against a hard surface until the
cartridge clicks into place.
When inserting the cartridge, do not use force. A successful
insertion should leave a buffer space for the pen tip to "bounce"
back after being pressed.
