Problem with faint printing on copy or rx faxes, I have changed toner, drum and cleaned the LED bar, calibrated it, selected dark during printing and ran a diagnostic check but it is still faint when printing, the drum and toner was checked in another machine and is fine, any assistance would be appreciated,

Cheers Dave

Incoming faxes have dark bands accross the page. The bands are 1/4" wide and spaced about 1 1/2 " apart.


Sounds like it needs a new drum. You'll have to replace the toner at the same time.

After changing toner it still has a grey spot in the middle of the page that does not print dark enough


The LED array probably needs cleaning. This is located on the lid that you open when changing the drum/toner and is a dark coloured bar going left-right across the lid. Clean this with a cloth. Also check the opening in the drum where you can see the green cylinder from the top for any small obstructions and remove if necessary. Any obstructions or dirt on the LED will line up with the print defect on the page and should be easy to remove. Be careful not to damage the green cylinder.

Just replaced toner - now it prints so dark I can't even read the fax


Most common cause is a dirty corona wire and or drum. If after cleaning the corona wire and drum the copies are still mostly black and smeared, the drum may be broken.

Oki Fax 4580 problem


Does this happen when you perform a test print such as an activity report or config page? if it does you may have a transfer roller issue. The transfer roller is the long black spongy roller directly under the drum, the metal rod in the roller conducts a charge that interacts with the drum. If the roller is dirty (usually chocked up with toner) the necessary charge is diminished and the image will be lighter. You will have to remove the roller in order to clean it, (TURN THE POWER OFF) there is a bendable plastic tab at the right side end of the roller that will release the roller. I personally drench the roller with metho and then wrap a rag around it and squeeze the metho/toner out (dont do this with lexmark rollers, they deform) let dry and give it a try, also check the end of the metal rod and where it connects for contamination.
