banding after some cm printing

[gorgino]

Hi , my xc540 after printing 1m start banding hard , some time i press the pause button and wait then the machine star the printing and looks perfect but after some cm the problem begin again. Is this a damper problem ?

I would say either the dampers or the pump/lines not drawing enough!

Check the dampers - the seals (o-rings) become swollen and the fit is not good. Also, check your caps as these may be getting weak at the seal to the head.
