• Vsg < 2.31 (at maximum power)
• Vsp ≥ 1.65
• Vt ≥ 2.64 or Vt < 0.20
Current readings can be viewed using SP2-221.
TD Sensor
The reading is considered abnormal if TD < 0.20 V or TD > 2.64 V. Abnormal readings 10 times in
succession will generate SC 390.
Detection of Toner Near End and Toner End
Toner Near End detected when either of the following occurs...
• Vt is at level 6 (see above table) five times in succession
• Vt > 1.85 five times in succession
Toner End detected when any of the following occurs....
• (Vt is ≥ level 6 and Vt > 1.85) "n" time in succession, where "n" is 50 by default but can be changed
to 20 using SP2-213. (Note that "n" corresponds to the number of sheets that can be printed before
Toner Near End changes to Toner End.)
• Vt is at level 7 three times in succession.
• Vt > 2.00 three times in succession
