HP Designjet 500 42 "
Microsoft Windows 10 (64-bit)

Good morning, I have the printer in question that is giving me a big problem. I replaced the heads, the cart and the bushings, the encoder strip and the carriage cable, but it continues to print as in the picture. Also alignment heads is not carried out .... do you have any suggestions? I attached photos of a print and alignment of heads ...20180129_122512.jpgHP desijet 500plus.jpg

I replaced the carriage assy with a reconditioned, but the problem remains ... maybe it was badly reconditioned, however I noticed that dirty a lot, as evidenced by the photos ...20180220_191556.jpg20180220_191605.jpg20180220_191611.jpg

Chances that 2 carriages have the same issue is possible but very unlikely.  Can you check trailing cable with a digital multimeter?
