Solution:

• Power on printer while holding both the + & - buttons simultaneously; release when “OKIUSER” is displayed.
• Press either the + or – button until “ENGINE DIAG MODE” is displayed; press the Enter button and “DIAGNOSTIC MODE xx.xx.xx” will be displayed.
• Press and hold both the - & On-line buttons simultaneously until “ENG DIAG LEVEL2” is displayed.
• Press either the + or – button until “CONSUMABLE COUNTER SET” is displayed, press the Enter button; you are now in the menu to set various consumables.
• Press either the + or – buttons to scroll through the various consumables, at the desired consumable press the Enter button and the last digit of the count will start flashing.
• Press the Cancel button to decrease the digit amount or press the On-line button to increase the digit amount; press the + or – buttons to move along individual digits in the count.
• Once the count is at the level you desire, press and hold the On-line, Cancel, & Back buttons simultaneously until the “*” reappears next to the count; consumable’s count are reseted to the number you specified.
• Press the + or – buttons to move to the next consumable and repeat at step 5.
• Once all consumable counts have been set to desired amounts that are below their end-of-life thresholds, you can use the Back, +, & - buttons to exit through the menus
• until “INITIALIZING” is displayed.

SOURCE: reset drum life on oki c5500n

try this:

1) Power on printer while holding both the + & - buttons simultaneously; release when "Okiuser" is displayed.
2) Press + or - until "Engine Diag" Mode is displayed; press Enter and Diagnostic Mode xx.xx.xx will be displayed
3) Press and hold both Enter & On-line simultaneously until Eng Diag Level3 is displayed

4) Press + or - until Local Parameter Set is displayed; release and press Enter

5) Press + or - until it displays Factory Mode; if it displays Factory Mode Twice with an asterisk next to one then it is in Factory Mode; Press Enter, Press + or - until it displays Factory Mode & Shipping Mode on the display; then press and hold On-line & Cancel simultaneously; when it stops blinking an asterisk should be displayed next to Shipping Mode, which becomes the default mode.

6) Power printer off then on to complete the procedure.

SOURCE: How do you reset the OKI c5800 drum?

You don't need to go through all that mess of replacing the fuse. The tone gets everywhere and getting the Drum unit back together with all the gears and shafts lining up is a real pain.
The Drum reset system is very simple. When the printer powers up and runs through its system check, one of the tests energizes the erase LED array built into the Drum unit. The reset fuse routes a small amount of low voltage current off this LED array. There is a contact on the end of the Drum unit that the printer senses. It there is voltage there (ie the fuse is good), the printer resets that Drums counter to 100%. If there is no voltage (ie the fuse is blown), the printer continues on its way.
All you have to do it act like fuse at the instant the printer sends power to the LED array.
There's no soldering, no screws to undo, and no toner all over the place.
The best thing is it takes about 3 minutes start to finish and cost $0.00!
Here's what you need:
• A simple volt/amp meter (an analog one works best, but digital is fine also) • Two pieces of thin wire about 300mm long. I used old telco wire. With insulation, its about 1mm wide. • A pair of scissors to strip the wire ends • X-acto or thin razor knife

1) Strip about 4-5mm off the one end of each wire and 25mm off the other end. Bend the 5mm end at a 90 degree angle right at the base of the stripped part. 2) Pull out the Drum unit (leave the toner cartridge attached to the Drum unit) 3) On the right end of the Drum unit (DU) there are three square brass contacts about 3mm wide. The right end is the end with the blue handle. Looking at the end of the DU, you are interested in the 1st and 2nd contacts from the left (they are the two closest to the screws on a c5800 cartridge) 4) Use the X-acto knife to lift the contact metal and slide the 90 bent end of the wire under the contact. Do this with the other wire on contact #2. 5) Put a little vertical tension on the wires and route them around the blue toner release handle. 6) Gently insert the DU/toner cartridge into the printer. Keep slight tension on the wires until the unit is seated. 7) Wrap the 25mm stripped end of the wires around the volt meter leads. Wrap one so it makes electrical contact, but you could pull it apart instantly at the right time. 8) Set your voltmeter to the lowest amp setting. I put mine on 200micro amps. Also make sure your voltmeter leads are in the correct holes of the voltmeter. You want the amperage or milliAmp holes not the voltage holes. Don't forget to turn the meter on. 9) Get prepared to pull one of the leads off of the one of the thin wires and turn on the printer. Don't be afraid to touch the metal of the wire; the voltage/amperage supplied to the LED array is very low and will not hurt you. A 9 volt flashlight battery is more dangerous. 10) About 10 seconds into the startup routine, you will see you voltmeter display a reading. Instantly pull the leads apart.
Congratulations, you are now officially a 1/16amp fuse.
Your printer will reset the Drum Unit counter and you have another 20K impressions (if the image quality is acceptable to you)
If you have any question, just respond to this post. I'll get the email and answer you.
Good Luck.
