Top 20 OKI C9300 Led Printer Questions & Answers

take a napkin and just clean it softly

take out the magenta cartridge. and make sure the edges are clean. There are little metal pieces on the sides where the sensor reads the cartridge. Also, make sure the "lock" on the cartridge is locked.

There should be a button that you can pull down on to open the duplexer. I don't know where exactly since I do not know the model. Just pull it and the door will swing open and you can remove the paper jam.

You have done some good steps for troubleshooting this problem. The next step would be to see that there are no obstructions between the laser, or LED array and the drum. you may also have dirt or an obstruction in the drum charging units.

A drum can print only a limited number of pages before failure - your drum has reached that number and must be replaced.

I'm having Adobe problems, but this pdf looks to have an explanation of your error message. Here's the link:

Hope this helps.

This machine is just a printer, so you can't make copies.

First of all unplug the printer from the mains (safety first). Get the toner out again and check for dirt on the contacts. Also check the contacts inside the printer itself.

In case of a problem or clarification, don't hesitate to post me a reply.

Ok above please find you service and repair manual, this is what the engineers use to troubleshoot and repair these units. Above that is your user manual, above that another service manual.

Abnormal temperature
detected by
fuser thermistor
(high-temp or low
temp.)

Turn power ON again.
Replace fuser unit.

first check not to be an issue with the mobile parts inside...after you are sure that all is ok mechanical..you should reset it to fix errors...Im not sure for the model ..but if it is not specified the procedure in the user guide(usually it is if has unusual way to reset) ..than you should try the general way ...and shut it down ..remove cord...put it back after 30 sec..than power it up,,and when you do that keep the power button pressed for 15 seconds...or try to keep it and release it every 5 seconds..if it beeps..Most models do reset on this if they do not have reset in the menu ..or special buttons or combination of buttons ...

Can you tell me the exact fatal error that you received? Any additional info might help us in resolving the problem.

Thank you!

I believe that it is built in the toner cartridge. It is sensed on the DC Controller

Remove the fuser and make sure the sensor below the fuser is still in place. If it and the paper is stuck inside the fuser then you have to buy a new fuser or a refurb one because you might have used up the life of the rollers that heat the toner onto the paper

Well hope this helps good luck. .

please you used the colour printer ? if yes then your check the csrtridge a refeling the towner and service the cartridge and service in printer and aply the print is ok.

you will have to clean the drum properly to fix this fuzzy printing problem.use the dry side of the cotton ball to wipe the drum clean. as you said-- If you get some streaks on prints, then wipe the "lenses" in the machine cover. its a very common problem with this type of printer.
This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya.

First thing to do is a hard reset. Merely unplug the power cord for 3 hours, then power up again.In order to dissipetate the remaining current stored in the memory. If error message still persisting then we procede some process.The toner counters will only be reset if a new toner cartridge is installed after the printer has displayed toner low. Installing a new toner cartridge before this message is displayed will have no effect on the counters. So maybe this happened and now the counters are wrong and have reached the upper point thus telling printer to hang on something is wrong....so
You could if brave and if you think this may be the case do a consumable reset...do each step properly and all will be reset to 100% life all drums and toners, that means that the indicators will all think they are full regardless of consumable actual status, so toner later will run out before machine prompts you with toner low, but counters will reset each time you replace a consumable when machine requests it.

Resetting consumables for OKI C7300,C7500,C9300 printer:

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) You want the "M TONER COUNTER"

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.
IMPORTANT

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%.

Good Luck...

The fuser is sold as whole unit. Just find one and order it and replace it yourself, it is a user repalable item.

This is the problem with the Thermal fuser unit. You need to replace it.
