3. Engine SP Mode Tables
Important: Use the procedure below to do the output checks for the fusing exit motor. If you do not
follow this procedure, a kink will form in the fusing belt sleeve, and the fusing sleeve belt unit will need
to be replaced.
1. Do one of the following:
• Open the right cover of the paper bank
• Remove one of the toner bottles
• Pull out the waste toner bottle half-way
• Remove the fusing unit
2. Enter SP mode.
3. Do the following out output checks:
• SP5-804-092 (Fusing Motor:CW:Standard Speed)
• SP5-804-094 (Fusing Motor:CW:Low Speed)
• SP5-804-098 (Fusing Motor:CCW:Low Speed)
4. Without exiting SP mode, turn the main power switch off and then on again.
Important: If you exit SP mode before you turn the main power switch off, the fusing exit motor will
stay off when the machine warms up. Heat will be concentrated in one area of the fusing belt sleeve
and cause a kink to form. If this happens, you will need to replace the fusing sleeve belt unit.
5. Do the reverse of what you did in step 1 (for example, reattach the fusing unit).
