Re: T8008 printer with message says "replace fuser"
The 'Replace Fuser' message on the 8008 can be cleared in the following way;
• Power the printer Off
• Hold down FORM FEED and ENTER and power the printer on
Keep the FORM FEED and ENTER keys held down until the printer displays SERVICE MENU - INFORMATION
• Press the RIGHT ARROW to MAINTENANCE, and press ENTER
• The Display should read MAINTENANCE - CLEAR FUSER, if it does not press the right arrow until it does and then press MENU/ENTER
• The Display Should now Read CLEAR FUSER NOT EXECUTE, Press the right arrow until the display reads CLEAR FUSER EXECUTE
• Press ENTER, and after a pause the display should read COMPLETED CLEAR FUSER
• Power the printer off and after about 10-15 seconds power the printer back on again.

Your problem is in the fuser. 50.2 means the fuser is not reaching temerature properly in the allotted time. It either has a burned out ceramic heating element or thermistor (hi/low thermometer). Replacing will fix.
Solution: Press "Additional Functions", Press "#", then press the
"Right Arrow" button till it says, "Printer", Then press "Set" then
press the "Right Arrow" button again until it says "Printer Reset" Then
press "Set" again, the display will ask you "Yes" or "No". Press the
"Left" arrow for "Yes", then press "Set". Now, unplug the power cord and
wait 5 seconds and plug back in.
The fuser is the heating unit near the paper exit, and that error means the lamp is burned out, the overtemp sensor is out, or the thermistor in the fuser is bad. About all you can do is replace the fuser. www.precisionroller.com will have a new fuser for you.
that means there is a fuser unit back side of u r printer this is the main unit where printing happens actually. I think there may be problem with fuser unit...may be paper jam or sensor problem..replace the fuser unit
To test fuser out of circuit make sure lamp and thermal fuse are not open circuit, and thermister is neither open or shorted
Fuser repair procedure from tec manual.

Please rate solution to your question "How can I check that new Fuser unit is ok?"
HI, Yes it definitly sounds like your fuser is not getting to the proper temp. I would call Samsung and have this printer repaired or sent back. If you purchased it recently your warranty should be available. Hope this helps!! Thanks
