My non-techy neighbour has purchased a Phaser 3600DN printer at auction. It is now giving him a
SMPS FAN LOCKED
error. The advice he fins is to turn off, wait and restart, but the error message returns. I have a feeling that it went to auction for that reason but if I can help him with a fix I can do the labour.
Any suggestions or a possible source for a relevant replacement board woudl be appreciated.
