Fuser Unit Fuser assembly Fuser kit for Samsung 3051 needs to be replaced.
There are 4 screws, 2 green hafts need to be turned up to release..it's easy to replace, no need to remove printer shell.
Once the unit was replaced, it worked ok.

Button on PC case is not working

Problem: Start up button is broken

On case as shown on picture, I used solder wire to imitate broken part
which allowed button to press and start up the PC.
Update:
Even better, press slightly tin which holds movable part, as shown on picture- to hold it without being able to move out. (thanks to Hrvoje)

Programs not visible, desktop is empty

Problem: Only Documents and settings folder is visible

The rest of folders are hidden.
Control panel - Folder options - View - select Show hidden files and folders,
Uncheck Hide protected operating system files
Then, you can unhide them, right click on folder and remove hidden check box.

But this won't bring back shortcuts inside start - programs, this will:

C:\Documents and Settings\Username\Local Settings\Temp - smtmp folder
has all shorcuts for start programs, copy them back:
folder 1 is programs - copy all shortcuts back to where it belongs; C:\Documents and Settings\All Users\Start Menu
folder 2 is quick launch - C:\Documents and Settings\Username\Application Data\Microsoft\Internet Explorer\Quick Launch.
folder 4 is desktop - C:\Documents and Settings\All Users\Desktop

However if you log in as another user, desktop is empty. Solution is:
run- cmd - regedit:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer
NoDesktop,REG_DWORD,1
delete it.
