Unfortunately, the pen is also renowned for being difficult to empty of ink, and difficult to flush with water. Even filling and using the pen is complicated. The pen sometimes requires coaxing (tapping, shaking, and centrifugal force) to get ink to travel through the barrel to the feed to the nib, and finally to paper. In its natural state, it is not an ideal beginner's pen.

1. In photo 1 above, the pens are a Pelikan M800 Souveran with a blue striped barrel; 5 Pelikan Level 65 pens, coloured black, red, white, yellow, and green; and a Pelikan Go with a green clip.

2. In photo 2 above, the flared caps are off, revealing coloured sections. The pen has a section at one end, and a rotary control at the other end. The steel nibs are fine, medium, and broad. The coloured section is the coloured outer tube. (Inside the coloured outer tube, is an inner tube which is continuous with the barrel.) The rotary controls are coloured green, yellow, white, red, and black. The section, rotary control, and flared cap are all the same colour. The control rotates about 180 degrees.
In photo 2, there is a light grey circular or triangular mark on the side of each control. Above this mark, is a light grey circular plastic prong, which sits in a circular hole in the barrel. The hole is about 1.5 mm in diameter. In each pen there is a total of two prongs, which sit in holes on opposites sides of the barrel. The prongs hold the control firmly in the barrel. One prong is light grey and easily visible, and the opposite prong is dark and usually difficult to see.

3. In photo 3 above, there is a dark prong on the control. If you decide to remove the control from the barrel, simultaneously depress both prongs firmly, grasp the control and pull it out of the end of the barrel. This procedure may need two pairs of hands to accomplish.

4. Photo 4 above, shows the Pelikan Level 65's ink bottle. The soft plastic bottle is compressible. The cap can be removed by unscrewing it. There is a valve in the cap.

5. On the right of Photo 5 above, is the top of the cap of the ink bottle. On the left are the rotary controls at the end of the yellow and the white pens. In the yellow pen, the control has been rotated anticlockwise, causing central depression. In the white pen, the control has been rotated clockwise, causing central elevation. The white pen is ready to be plugged into the top of the cap of the bottle. The yellow pen is not ready.

6. In Photo 6 above, the rotary control of the pen has been plugged into the top of the cap of the bottle. The control has disappeared inside the cap of the ink bottle. Continuous force is needed to keep the pen plugged into the cap of the ink bottle. Plugging causes opening of the valve in the top of the cap of the ink bottle, and opening of pen valve 1. The pen functions as if it has 4 valves. When the force stops, the bottle spontaneously separates from the pen, causing closure of the cap valve, and closure of pen valve 1.

7. Photo 7 above, shows the pen's components. On the left is the nib and the feed. Beside them, the red pen lies intact. Next is the yellow pen, and then the yellow rotary control. Last is the green control. The long thin stalk is attached to the rotary control. The stalk on the left looks shorter than the stalk on the right. This is because the yellow control has been rotated clockwise, but the green control has been rotated anticlockwise. Anticlockwise rotation makes the stalk move upwards, away from the green rotary control, and towards the section. If you look closely, you can see that I damaged the prongs when I depressed them. There is a black rubber ring on the control, near the junction of the control and the stalk. The ring seals the outside of the control and the inside of the barrel.
Replacing the rotary control:
To put the control back in the barrel, first find the rubber ring, and then put it on the control. Then line up the prongs on the control, with the holes in the barrel. Push the control into the barrel, and check that both prongs click back into their holes, which are on opposite side of the barrel.

8. Diagram 1 above, is a diagrammatic representation of the barrel and some of its contents. The rotary control is at the left end of the diagram, and the section is at the right end. The stalk is black, and moves lengthways in the centre of the barrel. The barrel is blue. The pen functions as if it has four valves. The valves are two way valves. Red arrows point to valves 2, 3, and 4. The blue parts of the valves are attached to the inside of the barrel. The black parts of the valves are attached to the moving stalk.
For diagram 1, the control is rotated clockwise. The stalk moves to the left. Valve 2 is open, valve 3 is closed, and valve 4 is open.
The pen is plugged into the bottle, the cap valve opens, and pen valve 1 opens. Fluid can pass from the bottle, through the cap valve, through pen valves 1 and 2, into compartment A. Fluid can pass from compartment B, through valve 4, to the section. Fluid cannot pass from compartment A to compartment B, because valve 3 is closed. Closure of valve 3 prevents continuous flow of fluid through the pen. In reality, compartment A is much larger than compartment B.
9. For diagram 2 above, the bottle is unplugged from the pen, causing closure of the cap valve, and closure of pen valve 1. Then the control is rotated anticlockwise. The stalk moves to the right. Valve 2 is closed, valve 3 is open, and valve 4 is closed. Fluid can pass from A, through valve 3, to B. Fluid cannot pass from B, through valve 4, to the section.
