I replaced the color head.
Changed the color head rank and refilled the dampers.
Then the testprint feature showed up and I had to load the vinyl as stated in the service manual and then the testprint would be performed.
Vynil placed and it checked the sensors (moving vinyl backwards and forward) and then gave a error message about illegal paper size or something. Could not clear this problem so I switched off/on the machine and performed the regular nozzle test print which showed some nozzles missing. Waited 2 hours and performed again the nozzle test print and now all are there in nice steps.
Then when I looked at the heaters display it was blank although the heaters are working. Found out the heater display flatcable was affected by previous inkspill due to the defective pump. The heaters were set to 50 degreees before the display cable went south. I assume the heaters work also when the cable is not connected except for the message and the buttons not working. I assume all regulation is done on the heaterboard. Found out the regular control panel flat cable is also a little attacked by the ink.
Both flat cables are 90 cm long and have 26 pins. Any one know a reliable address for these cables or is having defective machine with those cables.
Thanks in advance,
Paco
