Assuming you are using MS Windows then install FoxIT pdf reader which allows command line printing on Windows. Go to to get it. Make sure your OKI printer is the default.

Once installed you can print using the command, from my dusty memory -

Reader.exe /p MyFile.pdf

I don't use Windows any longer, now exclusively Linux, so I might be mistaken.

Cheers, Martin

Most 900 series codes are fuser related and you will need to replace the fuser unit to get rid of that code. what model do you have? The fuser codes are nomally 980 or 904. not 984. Verify that code please.

There's a small fuse in the drum that blows when it's first powered up after changing the drum. You can emulate a small fuse with an analog VOM set on Amps. With printer OFF, using a light wire like phone wire, connect the VOM to the drum terminals. When you power up, in a few seconds you'll see the VOM needle bounce one way or the other (doesn't matter). The moment you see that, pull the connection from the VOM. You've just impersonated a small fuse blowing. Here's an article on how to make that connection to the drum:

We had a number of these. On the LXMC logic board is TR5. OEM is marked B882. It's a power transistor. Replacement is NTE264. Solves the problem and also solves some cases where space motor seems weak even though it is known good.

The baud rate is automatically set by the machine when it connects to the remote machine. The machines start at the highest speed and drop down until both machines can send/receive without any errors then they send the pages. You can not manually set the speed.

Hi my reply was too long heres the second half..and ill retype the first as a comment

Try printing lighter prints, heavy toner saturation causes paper to stick to fusers and try to keep leading edge of print blank with no big blobs of colour for the same reason, ensure page sizes are set correctly in driver and machine tray settings and dont print outside margins , if you are about to print outside margins your printer driver should warn you, dont click ok if it does

Here is your user manual for your oki. and a link to oki print drivers to suit 610

Here is a link to Magic touch Australia that i thought has some good info re transfer paper use

Ensure your printer works ok with plain paper so we know it aint a printer fault but I'd say it due to how we are feeding the paper and how we have the paper type set and not feeding out the rear as I also think we should be.

Oki does the best colour prints nice and glossy, I dont think many come close to such great colour prints in fact I only like Oki and Kyocera stuff in Colour toner laser machines. Stear clear of cheap non oki toners and supplies because they cause heaps of issues and wreck printers and give many print quality issues, I dont work for OKI directly just telling you how it is in the field ;)

Let me know if you need more help and how you go

You are doing the absolute worst thing possible: you are trying to print on a medium that is specifically forbidden. This is why : the printer is a laser model, in it the ink is a dust that is baked in the paper with a lot of heat; the transfer paper is a special type of paper that absorbs liquid (not dust) ink in it and releases it when heated; the result is that not only the ink dust doesn't catches on the paper but the little that does gets lost when the paper is heated inside the printer, messing everything in there. This is why it is totally forbidden to print transfer paper in anything other than an inkjet printer - and especially forbidden for a laser printer like yours.
So not only it will never work properly but every time you try that you damage a little more the printer. The only way you can do the job is to buy a simple and cheap inkjet printer (less than $50 at every pc shop) and use it just for that.

Please check the settings in your printer that you have selected correct paper type and tray from which you are printing. Also while giving print command make sure paper size is same.

Welcome to Fixya. Service Call 980
This error refers to the Fuser unit

- Media coiling error to the Fuser

- Media is coiled to the Fuser

- Turn off the power supply

- Replace Fuser

It means that the Fuser of your unit needs to be replaced. If you still have warranty with OKI you can ask them to repair the unit if none then you need to bring the unit to a Service Center for the Fuser to be replaced.

If you have questions please let me know. Thanks for using Fixya

This caused by not having the correct printer font. The font used on screnn is not the same as the ones used for printer.
Most cmmon fonts include both versions automatically. You may check your printer setting from the control panel, printers, find you printer, and right click it, choose Print Preferences. From the Layout tab, go to advanced settings, then find the TrueType line. Click on it and a drop down box will be available, choose Download as soft Font.

Yours may not be exactly the same, but look around for similar setting, and hopefully, this wil fix the problem
