I would think you have broken ribbons cables to the cyan and magenta LED print heads. As all the heads are the same I suggest you swop the black and cyan print heads around and see if cyan prints and black does not. That will prove is the print heads are ok. If they are then the ribbon cables need replacing or they are dirty at the heads. It could be just a case of unplugging them, clean them, then plug them back in again.

All you need to do is unlock the scanner. Just open the flatbed cover and on the left edge is the slider for the lock. Slide it towards you and that's it unlocked.

Open the rear cover and in the centre of the curved black guide you will see a small black lever with a silver spring on it. this is a arm to the jam sensor. check it moves freely and returns to its upright position. If ok the blow air under it into the actual sensor. Check the pickup roller is not smooth. If it is its rubber tyre can be rotated so the good part touches the paper.

you may have to make another tray the default tray
then you select the paper size to print on and put the size paper in the default tray

You say you have checked properties etc but have you selected mp tray from printing preferences in the driver. Remember the driver overrides the printers own settings.

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

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.

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.

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.

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

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.

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.
