No test print

[signs1970]

Hi all
It started when i gave the JV3 a clean when the problems started. Couldn't get the Black or Magenta to print - No suction so changed all the capping station seals. Then cyan wouldn't print-found i had 1 cracked head adapter nipple which i replaced. I got negative suction through the fixed heads - Now it won't test print at all , goes through the motions but no ink down -
The head cables aren't the best but no errors are being thrown
Dampers full
No air in lines that i can see

when this happens on my roland, i slide the print heads off the capping station, remove the dampers, place paper towel under heads. fill syringe with solution, connect to head nipple with tube, and blast out the head. opens them right up.

All Fixed
Pulled apart station and found
Black & Magenta head - pump not sucking - changed to spare line on other pump
Yellow & Cyan Head blocked - installed spare head
LC & LM broken adapter
Also changed all dampers, adapters and head cables
Tip from spare parts man -push dampers on old adapter and spin around to stretch o ring a bit before installing
