I have a KM-C3225E which has had the developers, drums, transfer belt, fuser unit and laser unit removed. All units were vacuumed and replaced back into the machine correctly.
However, the machine is now giving almost blank prints. The attached PDF is a printer status page. You can see the coloured header broken up across the top of the page. So I'm wondering what the cause of this fault is. I've done the following.
- Checked transfer belt positioning (seems to be located correctly)
- Checked all drum and developer units are locked in correctly (they are)
- Checked there is drive to all drums and developers (appears to be)
- Checked the transfer belt has drive (it does, and must do to get some image)
- Swapped the transfer belt with a 2nd hand unit (no change)
- Swapped the black drum with a 2nd hand unit (no change)
- Swapped the black developer unit with a 2nd hand unit (no change)
- Inspected the laser unit (all seems fine)
- Ran a laser clean, dev refresh and drum refresh (no difference)
If you look closely at the PDF you will also notice black background (looks like another faulty part ) but also - in my opinion - proves that the image on the drums is being transferred to the belt correctly. In theory this only leaves me with the charge rollers, developers, laser unit or electrical components.
Any ideas???
