CHAPTER 8: PRINT DRUM SECTION
[ 8 - 5 ]
4. Inking Mechanism
The ink is pumped into the print drum from the ink bottle when the ink sensor in the print drum no longer
detects the ink in the drum while the drum is rotating with the main motor ON.
The pumped ink is distributed on to the squeegee roller from the holes on the ink distributor.
The ink distributed on the squeegee roller makes a long ink bead around the driven roller located between
the squeegee roller and doctor roller. Once the bead of ink touches the ink sensor the ink motor deactivates
to stop the inking action.
There is a small gap made between the doctor roller and squeegee roller. From this gap the ink from the
bead of ink transfers onto the inner surface of the print drum via the squeegee roller.
The overflow sensor is located in the print drum to stop the machine to prevent ink overflow in the case the
bead of ink for some reasons becomes too large.
