Hi Folks,
I am having a headache while trying to fix a Canon refurbished iRC3580Ne.
It ran fine for the first 25.000 copies than ITB Belt was torn apart.
I replace it with another one and in less than 1000 copies it tears down the second one.
I thought the process unit might be somewhat distorted so I pulled the process unit from another working machine and switched it.
When I turn it on - I get color displacement in both directions (horizontal & vertical).
I put back the old process unit to see if the problem dis-appears but the displacement is still there.
So I tried everything I know (I am listing here)
1. RG - Clear (in level 2)
2. P-Print and DC-CON Clear (than put back old values)
3. MN CON Clear
4. Auto Color mismatch
5. Quick Adjust & Full Grad Adjust
6. Clean and Re clean the patch sensors
7. Checked SL1 for opening in Service mode
8. Switched the secondary transfer ext. roller
9. Switched the M1 motor
10. Switched the DC Controller
11. Switched the laser unit
I am out of ideas....
