Original Roland XJ-740 / XJ-640 / XC-540 / LEC-540 Print Head Board – 6700731100

Roland part number 6700731100 (ASSY,HEAD BOARD XJ-740) is the print head board for the SOLJET PRO III XJ-740, XJ-640 and XJ-540, the XC-540 and XC-540MT printer/cutters and the VersaUV LEC-300, LEC-330, LEC-540 and LEJ-640. This is a genuine, original Roland part – not a copy or compatible replacement.

Mounted on the carriage, the head board receives print data from the main board and generates the drive waveforms for the print heads. If it fails, the printer may report head errors, stop during initialization, print with missing colours or bands of missing nozzles, or produce random dots and streaks that cleaning cannot fix.
