at the begining we have bead carryout and light background on yellow, i thought about aged developer and changed it-didnt help (after half k prints the problem returns) i had before this problem on other colors and resolved it after drum have been changed. this time it didnt help. also having vh/vm fault (9-624) after performing dc933 (LDs judge NG). when adding new developer- all fine but after 500 prints developer goes to trash. also note the TC value felling down from 140 (after adding new material) to 0.
changed:
esv sensor
drum module
developer assy
developer material
swaped:
ros
halftone pwb
developer bias hvps
charge/preaclean hvps
cleaned every sensors
did dc301 after it vh/vm dissapered but after max setup and some prints returned
and still without any changes
any ideas?
