Designjet Z6200
Microsoft Windows 10 (64-bit)

We have several Designjet Z6200 printers, and recently when the printing starts there are random printhead marks, all across the paper. Always the same printhead. We updated the firmware, replaced already the encoder strip and sensor, the line sensor, the PCA board, the printheads, and still the same pattern appears randomly. I've uploaded a picture for reference.20211130_010738.jpg20211129_183545.jpg
