Hoping someone can help. I had to replace gears, motors and bearing in the LCT base of a C451. That all went well apart from the shear pain of getting to the parts.
When the machine was put back together everything came upa dn no more grinding and jamming. On checking copy and print quality it was evident there was a significant problem as the copies and print would only come out at about 20% density.
I have done the following.
1. Changed all image units
2. Changed transfer beld
3. Changed transfer roller
4. changed EEPROM and reprogrammed
5. cleaned all terminal and sensors
6. Checked transfer roller lift motor
7. Cleaned IDC sensors
8. Checked all transport gears and morots.
9. Checked all connections on PCB correct and firm, and reseated all.
10. Checked all connection FROM PCB board and reseated all.
When stopping the machine halfway through a print or copy it is evident that the image on the transfer belt is strong and correct, but it is not tranbsferring across to the paper.
I have referred to KM Tech support, but as yet they can't give me anything else except the manual or existing solution reports.
I am about at my wits end, if anyone has come across this problem before and has been able to solve it I would very much appreciate it.
