Hp9000s breaks in print head test

[monny]

Can anyone tell me what this means when printing a printhead test. Happens once in awhile. Every 1/4 inch hairline break. In black, sometime Light Magenta. Run a printhead recovery and and next test OK.

see the capping conditions, if bad replace it! Check if you got any leak on ink circuit, mostly at gampers conections on carriage. The problem is that the printhead is full of ink when start the print but if the print is to long, the capping or leaking problems, dont reffill the printhead white ink!
