Article 4: Capillary Pen Inking Instruction
To start the capillary ink flow in the pen, follow the procedure below. It is no longer necessary to use a ‘pen starter’ or ‘duckbill’ to prime the pen.
PRIMING PENS
- Completely remove cap and capillary tube from bottle.
- Using a ink filler provided, extract ink from the ink supply bottle.
- Fill small bottle to approximately ¼ full. DO NOT OVERFILL. Overfilling the ink bottles will not improve ink flow and will increase the possibility of spillage during transit.
- Grasp the bottle by the cap as shown in (Step 1) and tighten by rotating bottle with free hand.
- Gently squeeze the bottle until the ink is forced to the end of the pen (Small bead of ink should form at pen tip.)
- Keeping the bottle squeezed, slightly loosen the cap again by rotating the bottle (Step 2).
- Release the pressure on the bottle.
