Did I blow a fuse on my Laserjet Pro 400 MFP

Hp Laserjet Pro 400 MFP

Hi guys, 

I am afraid I have made a mistake and I am really hoping theres a cheap solution to rectify it. Basically I found my dad's Latesjet pro 400 and decided to plug it in. It turned on, then turned on and off repeatedly and went compeltely dead. 


Now I know what the issue is, I didn't realise this was a printer he brought in from the US and we are in Pakistan now. So the printer required 110V power supply while I was providing it with 220V. So I have basically single handedly fried this machine that costs over $400. 


Does anyone know how I can fix this? We dont have an HP service center here (not one that I know of) and so I wont be able to take it back to HP, my best bet is to take it to a local printer shop and see what they can do. But just so I know what I am looking at, is there a fuse in there which once replaced will fix the printer and I will invest in a step down voltage regulator and blissfully use my printer? 


Thanks in advance. 🙂

Sorry but the printer is now toast. Not only was the dc controller/powersupply blown but you also blew the heating element in the fuser so the cost of repairing will be more than a new printer. Sorry.

The laserjet printer comes in two power specifications i.e. 110 V and 220 V.


Internal Parts of Printer like Formatter,  SMPS , Fuser etc will be different with respect to the power specifications.


There are possibilties that SMPS unit has got damaged or smps , formatter and fuser[heated rollers]  have got damaged.


For this you need to contact the HP Support.
