Fusing
D0CA/D0C9/D0C8/D0CB 4-166 SM
*1:Make sure to keep the door closed when executing SP5-810-002 (Fusing SC Reset Hard
High Temp Detection). If executed with the door open, the SC will not be cleared. If the SC
reset procedure is executed when the door is open, "SC reset failed" will be shown without
blowing the fuse for new fusing unit detection.
If the door is opened during the SC reset procedure, the fuse is blown, but the SC reset
procedure is not completed and "SC reset failed" will be shown.
“SC reset failure” will be shown when this SP (SP5-810-002 (Fusing SC Reset Hard High Temp
Detection)) is executed if an SC other than SC554-00 occurred.
*2: If there is no fuse for new unit detection (such as in the fusing unit that comes with the
machine from the factory), install a fuse.
•
Never use a damaged fusing unit.
•
Inspect the entire fusing unit carefully if you will continue to use this unit.
