Power ON
Error displayed?
     When Deve Home Position
Sensor Error occurs:
→  Go to “FIP-1.46”
     When an ID Error occurs:
   XERO → Go to “FIP-1.9”
 Y Toner → Go to “FIP-1.13”
   M Toner →  Go to “FIP-1.17”
   C Toner →  Go to “FIP-1.21”
   K Toner →  Go to “FIP-1.25”
     When Deve Home position 
Sensor Error occurs:
→  Go to “FIP-1.46”
 PLC sequence
*3
(30 secs or more)
*1 : Rotary rotates 360º plus a little more during 
Home Position correction and 720º during
execution of the PLC sequence.
*2 : By ADC TC correction, the target density
value of  TC  is being corrected according 
to the developing machine drive time.
*3 : The PLC sequence creates and reads ADC
patches  to adjust toner and image density.
Yes
No
