Original Roland XR-640 / XC-540 / XJ-740 / FH-740 Power Supply ZWD225PAF – 1000000538

Roland part number 1000000538, POWER UNIT,ZWD225PAF-0524/J, is a power supply unit used in the SOLJET PRO III XJ-540, XJ-640, XJ-740 and XC-540, the SOLJET PRO 4 XR-640, the FH-740 and the AJ-1000 and AJ-1000i. This is a genuine, original Roland part – not a copy or compatible replacement.

The unit turns mains AC into the low-voltage DC that powers the printer's control boards and drive electronics. When it fails, you may find that the printer will not turn on, starts and then dies during initialisation, restarts by itself in the middle of a job, or throws random motor, carriage or communication errors that disappear after a restart. A hot smell, buzzing from the unit or bulging capacitors are signs that replacement is overdue. Fitting a new power unit removes an unreliable supply as a cause of intermittent faults.
