Hi,
You probably have a damaged IDOB module. Open the cover of ink zone push buttons and check if green LED on IDOB module is blinking.

 

the module IDOB i try in another machine and funtion normally in another machine

 

The display is not seen in board

 

Hello,

Did you solve the problem with ink zone error?

 

If all modules with can bis are ok you must see TAS module below ink zone

Pls check yellow led on iopb/icpb can module under inkjone.
If light is flashing ok .
Have you open ipc and change plugs???

 

Hi sir .
does this problem exist from the start of the machine??

Hi my friends, we live the same problem on SM74-8 color. 2002
How you fix your problem? is it software or cable problem?

 

Hi Guys. We also have the same problem on our SM 74 4+L. Only the disable diodes are coming on when the order is being set. when the job is sent to the machine and the press running, we do not get the coarse and fine diodes . even after selecting an individual printing unit from the production display. or selecting the light pen function . there are no faults or errors indicated on the CPV 104. Can this be as a result of a faulty or the operator is not setting the order properly . please assist
