Clean the laser scanners

Hi. You may have to reinstall driver software.

You need to do s head clean. This could take 2 or 3 goes but should fix it you will find head clean in the maintenance settings. It eats the ink so only do as you need. let me know how it goes. Regards Craig

If the paper under the crease has print and the fold is "glued down", it is most likely to be a problem with the fuser. Try removing it and look for evidence of warping in the pressure roller. If the fuser looks clean and tidy, go to the other end at check over the paper tray and paper feed mechanisim. It is possible the paper is catching on something at the start of the process. This is most likely if there is print over the crease but not under the fold.

Since green is made of blue and yellow, I suspect you need a new yellow toner cartridge.

The thin lines are caused by a worn out drum. Remove each drum in turn and look at the surface. It maybe hard to see the scratches and if so then send solid blocks of the primary colours one at a time and that will prove which drum is at fault.

Although the drum life is at 65% it could still have a problem. It could be that the end of the drum is starved of toner or there is lumpy toner in the drum. Take out the black drum and give it a good shake then a gentle one to level the toner out and refit. Had the same with a canon unit 2 weeks ago. If still no good then a new drum is required. I bet you are using recycled drums!!

Drums.

Here is the # for OKI support they should be able to walk you through the problem! 1-800-OKIDATA (1-800-654-3282)

Where your network cable plugs into the printer there should be a green led on and possibly an orange one flashing (Shows data passing thru). If neither are lit then try another network cable (may be stretched). If still nothing then just try another network port. if still nothing then yes the network port which is part of the main board will be U.S. and new main board will be required. maybe expensive.....

When you say "Cleaned the lens" I presume you mean the four LED print heads. Use a spirit to clean them with if the toner dust is hard to remove. I usually just use a finger and wipe the entire length. Make sure there is no foreign item laying on the drum top where the black plastic film is as the led head may not seat properly on it. Clean all the silver high voltage springs down the left side of the printer. They make contact with the drums. If you still have a problem then try printing solid colour blocks ie Yellow, Magenta ,Cyan and Black . This will identify which colour is giving the problem . Change that drum and all should be well.

If you have all the led's lit and they are not flashing it means the printer is in download mode. In other words its waiting for you to download new firmware. Look at OKI's site and find the firmware and follow the instructions. That's why you cant install drivers because the printer no longer knows what it is!

Inspect the rollers for dirty or damaged surfaces. Clean up any loose toner or other debris in the machine. Note: avoid touching any roller with bare skin; especially in the fuser section or the photosensitive drum in the toner section. Skin oil can cause poor print quality or premature degradation of the roller surface.

It would help if you said where the paper jam was. However the fact that it was ok until you cleared the jam indicates you have knocked something out of place. Its just possible one of the high voltage contact springs that touch the drums has stuck in and no longer makes contacts with one of the drums. Make sure all the semi circular springs move in and out freely. Also check the led heads in the top cover. Make sure all the cables are seated in the heads ok. Make sure all the heads are in the same position and one has not turned around. Retrace your steps as your drums seem to be problem.

Suggest you order a black drum, which may include a black cartridge. Replacing BOTH the cartridge and the drum should solve the sensor problem, then you can swap parts to isolate where the problem is.

Seen this many times. Its because you are using recycled drums and/or toner. With the genuine items you will find the magenta will be more red than pink.

You do not say what operating system you are using?. They are both compatible with Windows 10.There should be no conflict between the two printers. Use system restore and go back in time before you had the problem. Disable your antivirus and try and install them again. That should work.

I cannot understand why you are using sublimation paper on an LED printer which uses toner. I always thought that sublimation printing is used with dye and not toner. Why it worked in the first place is odd. Anyway I reckon you have worn out the fuser and or the fuser is not reaching temperature which is why its not fusing correctly.

A printer only prints what it gets from the pc/network. Therefore I would uninstall and reinstall the driver on your pc/server. Do not use the cd provided but download the driver from OKI's website.
