Hello ,

I have the same issue on canon C600.

Tried Dc-con pcb
Sensor
New bottle
Updated firmware
Full format and new harddrive (i know it is not related)
Wires seems all ok .

I am reading the 5V as 3.6V which seems to be the problem for me . There is something connected to the dc con that is causing this issue .

It is always seen as the bottle is full. Which gives you around 6K prints before it stops completely.

I cleared the DC and set all the default values in . Backup the dc . And each time the machine stops just restore the dc , restart and calibrate and the customer can print again.

I know this is not a solution, but at least the machine can print
