My OKI C9600 printer has problem related to led head with error code 133. This error msg indicates Cyan led head is failed.
There are some reasons that leading to this failure. One of them might be caused by drum. If drum is dirty or is overflown by toner.
So you may test C Led head to know it is OK or not. How to test ? Try changing with another Led Head such as Y,K, M.
This is the way I did, and my printer is OK now.

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.

See if your printer has some sort of reset button. contact Oki for tip.

Maybe you have to reload the software in printer. Try also unplugging printer while turned on. Then press and hold the power button for a minute or so. then plug back in and press power button.

5) Press "ENTER" again.
6) Will appear "TABLE 1" message.
7) Press "ENTER" until "EXECUTING RESET" message appear. ...............the "NV-RAM INITIAL" message will BLINK.
Tada....This procedure reset TONER, DRUM, FUSER and BELT...life counts
8) power OFF printer, wait 10 sec, and power ON again..

To access Service Mode in C9300 power ON printer with 0, 1, 6, 7 at same time...you can do some good damage in there!! (I warned ya!)

Resetting consumables for OKI C7300,C7500,C9300 printer I think!

1. Hold buttons 0 + 1 + 6 + 7 on startup.

2. Press button 0 several times until "DIAGNOSTIC MODE xx.xx.xx" shows.

3. Hold buttons 2 + 3 until "ENGINE DIAG LEVEL 4" shows.

4. Press button 1 to scroll to "COUNTER SET".

5. Press button 2 to scroll through menu items (button 6 scrolls backwards)

6. To alter the value of an item, first press button 3 to select the digit to be altered. The selected digit will slowly flash. (Button 3 moves to the right through the digits. Button 7 takes you to the left.)

7. Then press button 2 to increase the value of the selected digit. Press button 6 to decrease the value.

8. When the changes have been made hold buttons 1 + 3 + 5. The screen will flash three times and then an * will appear on the right of the screen. The new value is set.

9. To leave the counter set menus, turn the printer off.

Each colour toner counter shows life as percentage used. So a toner showing 30% has used up 30% of its toner. 100% would indicate a near empty toner. This is the reverse of the toner life shown from the "usage menu" when the printer is in normal operation, which shows the toners as a percentage life remaining. You will want toner showing 00%. note:this is oposite of what you see in user mode
Some models exhange these steps

3) HOLD 0 + 4 "ENGINE DIAG LEVEL 2" shows

4) Press 1 to cycle to "fuser unit"

5) 2 to scroll to TONER

Reset to Default settings, if that does not work, shut down printer, unplug power from printer, shut down computer unplug power from computer, wait 20 seconds, plug power in to computer plug power in to printer, wait 5 seconds, boot computer, turn on printer.

NOTE: This should solve most problems with printers.

If still not working you have a faulty Toner unit.
