• Description: Toner Supply Error 1: K
  The machine detected 10 times that the amount of toner applied to create the black ID sensor pattern on the drum between sheets (SP3101-1 ID Pattern Display - Applied K) was less than the minimum threshold setting (0.0 mg/cm2). Also, the total time for the operation of the sub hopper clutch (SP3251-1 Tnr Supply Time - Sub Hopper CL: K) exceeded the threshold of 65K ms.
• Causes: • Toner end sensor cleaning spring broken, mechanism defective • Toner end sensor loose, broken, or defective • Replace toner supply unit

• Code: SC357
• Description: Toner Supply Error 2: M
  The machine detected 10 times that the amount of toner applied to create the magenta ID sensor pattern on the drum between sheets (SP3101-2 ID Pattern Display - Applied M) was less than the minimum threshold setting (0.0 mg/cm2). Also, the total time for the operation of the sub hopper clutch (SP3251-2 Tnr Supply Time - Sub Hopper CL: M) exceeded the threshold of 65K ms.
• Causes: • Toner end sensor cleaning spring broken, mechanism defective • Toner end sensor loose, broken, or defective • Replace toner supply unit
