The HP Partsurfer Site here lists parts for the Laserjet CM1415fn. I do not know which model you have, but select the country, then search for Laserjet CM1415fn. There are a few models that map to this model, select the proper pone and then look for the power supply. Note there are 110V and 220V models, make sure you pick the correct model. It appears the parts are no longer available from Partsurfer, but find the part number for the supply you need and then do a search for that number. I did this for a few of the options, it seems that are several suppliers that offer the supplies new or refurbished.
