I have the Phaser 7800GX and has 44,000 sheets through it. I am getting toner smudging and missing toner on the page. What do I need to replace to resolve this issue? Fuser is 87%, Belt Cleaner is 70%, Transfer Roller is 76%, Transfer Roller is 90%, Suction Roller is 62%. All the imagers for the color toner are at 73% and black is at 65%. Running Xerox glossy cardstock 110lbs.
Make sure the weight setting (gsm) is correct. Replace the fuser. Make sure the total toner coverage is not greater than 260 percent. Try a setting in your driver one setting heavier. Load the latest firmware. Delete driver and install the latest. Have a tech do a NVM reset.
Double checked all of my settings... Everything is just like I have had it for the last year. Replaced the fuser and did not make any difference... Any other thoughts?
