The drum lock error is caused by one of two items. Either the drum has seized and will not turn or the drum motor has failed and requires replacing.

Is printer working properly?Then why update firmware and risk winding up with a nice big paper weight when the update does not take. Make sense? You only update when you are experiencing an issue and are desperate.

You have been advised and forewarned. Good luck if you proceed.

then you select the paper size to print on and put the size paper in the default tray

I suspect you have sent the job to the MP ray and it wants you to put paper in it. Cancel the job and go back into the driver and make sure paper source is set to the cassette.

You probably did not turn the power off when you changed the fuser . Turn off and take the fuser out. Turn on and wait for it to say the fuser is missing. Turn off and refit the fuser. Turn back on and see what happens. Hopefully all should be well. You do not say whether you are actually are using compatible toners or genuine

Where the paper exits the printer you will see 3 black sensor arms hanging down. 1 is the exit sensor and the other 2 are job offset sensors. On of those 2 will be stuck. Just gently free it and all should be well.

Then sorry but that is what you need to do. OR buy anew printer.

This is interesting. there is no reference in the service manual to this but I suspect the error is corruption in a file. It depends what you were doing when this occurred. Where you updating firmware for some reason to cure a problem? or just sending a file to print which maybe corrupted? Repost if you need further help.

Your printer does not have a waste toner bottle. Waste toner is stored within the transfer belt. When full it will give you an error indicating its time for a new transfer belt.

Service Error 14 - PCL/XL software error. That's a main board fault. It may need a firmware update. That's a job for an OKI engineer as a mistake could destroy the board.

For the printer to do this of its own accord makes me think the main board has thrown a wobbly. As you know how to get into the maintenance mode, scroll to menu reset and this will reset the eeprom. I doubt if it will cure it without new drums. You can buy on the internet a stick-on fuse for the drum which will blow and reset the printer into thinking its a new drum. Do this for all the drums and it may just do the trick. If its toner related then only genuine toners will cure. Anyway the fuse trick is the cheapest option. You may think why drums when its toners. That's because you need to fool the printer into thinking parts have been changed and it may have a knock on effect. Its worth a try.

This machine will most probably require the main board as sometimes the heads can get knocked and temporarily disconnect. I have had this a few times and replaced many boards (the fuse blows that supplies the heads on the board).

Also, before replacing the board, the values of the faulty board will need to be pulled off with MUWIN and put onto the new board (meter readings and consumable usage).

Error 001b means the dev motor cannot turn. The most common problem on this extremely complicated system is that a toner has not been locked correctly and has come loose thus jamming the drum and preventing it from turning. The easiest way to resolve this is to remove the front cover which will give access to the drum mechanism. You hopefully may be able to then push the unlocked toner back into place. This type of printer is a pain when it goes wrong. Have not seen one in years even though only came out in 2009. Good luck.

Just to confirm that Jeff Hughes is correct. 928 does refer to paper wrapped around the fuser rollers making the thermistor see nothing hence the 928. If there is no paper in the fuser then it will need to be replaced. Remember to turn the machine off when removing or replacing the fuser.

There are some toners out there that do not have the "Chip" that makes contact with the printer itself. If you have the old cartridge then you can prize out the chip and fit it into your new cartridge. that will get it working again.

In the metal chassis there is an oval hole. This aligns with the back of the drum where you see a silver disk and hole. A light beam shines from the oval hole in the chassis into the back of the drum. This sensor that emits the light will be covered in toner hence no light. Just get a cotton bud and poke it into the oval hole and you will end up with toner on the bud. Replace the drum and all will be well.

Error code 134 on the OKI C711 refers to the white ribbon cable that plugs into the Black LED head. If it has come out of the head then check that the silver contacts are in good condition and none are touching each other. If any of them are touching each other then its a certainty that fuse F12 on the main board will have blown. If they are good then push it back in but this must only be done with the power off. I cant remember whether the 711 has a plug on the end of the cable or just has silver contacts. If F12 has blown then you cant replace it as its part of the board. Only a pcb repairer can change it or fitting a new board.
