2. "CHANGE INK" Display Timing
When HIGH (5V) is output by detecting ink while the drum continues to rotate 20 times (the number of
rotations varies depending on the printing speed.*) during printing, it is detected that the ink pack is empty,
"CHANGE INK" is displayed on the error display, and printing stops. At the same time the power for the ink
motor is turned off.
*The drum rotates until "CHANGE INK" is displayed after HIGH is output from the ink detection PCB unit
during printing. The number of drum rotations varies depending on the printing speed as follows:-
Printing speed
