Hi, one of my customer complaining that theres a dirty line in the middle of A4 paper around 10cm. it is not too visible but u can see it even for the very 1st page. i did many things but no cure including
1. blade changed , drum changed, primary charge changed
2. changed scanner lamp, cleaned scanner unit, cleaned mirrors and cleaned glasses with spirit
3. cleaned laser unit
4. cleaned transfer roller
it doesnt cure even a little .... i dont think developer cylinder will cause this problem isnt it?
