7 Drum Section
1. Description
The ink control section is in the drum unit. The ink control section is supplied with ink in the ink
pack attached to the drum unit by the ink pump motor. The ink control section has an ink detection
function, and is always supplied with a fixed amount of ink. Printing darkness is adjusted by
changing the gap between the squeegee roller and the ink roller. Replace the drum for each color to
perform color printing. (Before replacing the drum, press the drum removal button to move the drum
to the drum home position.) The drum switch detects whether a drum unit is installed or not. When
the drum unit is not set correctly, the LCD panel displays "NO DRUM".
