Samsung Xpress C480FW prints black pages

[depanninfo06]

Hello,

I got a new problem, this time with a Samsung C480FW, at the beginning it was just paper jam in fuser. I changed the fuser but the problem still here. I disassembled the printer many times, cleaned it and suddenly, the test page is almost all black. I searched on manual what can cause this and find it's the HVPS on the printer. Is it sure or it can be another thing ? What damaged the HPVS ? What can i do now ?
Small precision when i print on color almost all black page and with black and white almost all white pages
If you can help, i will be grateful.
Thanks in advance

Either you blew the HVPS or you cabled it wrongly. This is happening as the imaging units are being sent too high charge.

Your original problem could be down to paper rather than fuser unit being fault, as most jams at fuser are not caused by the fuser.
