Question about OKI B4350 Laser Printer
My printer is putting out pages with faded print on left hand side. I have already purchased 2 new drums since Jan. I thought there might be a problem with the drums. Have put in a new cartridge and no change. Can anyone tell me what the problem is? Also, have done the cleaning page. Nothing seems to help.
This type of printing defect is normally caused by 1 of a few problems - the easier one first:
1. Toner cartridges sometimes do not have the toner evenly distributed - close the toner cartridge and inspect the hopper right below it for even distribution of toner.
The harder ones:
2. This type of defect can also be caused by dirty charging section - for the drum to pick up the toner it must be charged electrically prior to exposure - if the charge grid is not clean then it will not give the drum an even charge - not sure were this is in this printer yet - looks like it comes as part of the drum kit so this should not be causing this issue.
3. The last and most difficult to check is paper alignment with the drum - is the paper contacting the drum evenly - look for possible problems in the paper path with the drum unit removed - look for something uneven around the area were the paper contacts the drum
