Ok so the problem is solved I'm printing now for 3 weeks and lines don't appear anymore but i don't know exactly the cause because I change the TAB and the new one don't have contact with belt but i also change all the HAK (hybrid air knife) system because i noticed it was worn in the middle so...
I change all the pretransfer with grid in November, I send photos off the entire zone and the pretransfer. It seems like there is wear in the middle of the zone like in the "cylinder".
Yes there are thin lines etched into the PR belt especially in the center zone, but even after I change it and perform belt setup, a single line appear in the middle but at low intensity and the more I print, the more lines appear until I arrive at the state of the photos
Didn't found the reason yet, I also change the 062K31012 IMAGE MODULE ASSY (LAMP) and install the 607k15301 UPGRADE KIT but it didn't change anything...
The local Xerox services didn't know what can cause this lines and they tried for 2 months to solve the problem but didn't succeed...
Any...
Lines appear on print principaly in the middle like in photos. It appears on all CMYK colors but with diferent itensity. More sheets I print more lines appear...
Need help, any ideas?
