Fatal Error message 428056ec + 4280999c tried the method sent to me but could not get to diagnostic level 2. Do I need to replace the drums at all, I have plenty of toner, The waste toner has 2 readings. 2 & 6 Regards JB

Did you test before replacing ? Do you know how it work's ?

Fuel Level
The body control module (PZM) monitors the fuel level sender input in order to determine the current fuel level. The PZM filters the input and sends a message via the Class 2 serial data line. The IPC receives this message and displays the current fuel level. The fuel level is sent from the PZM to the IPC at changes of 0.5 L (0.02 gal) or on the request of the IPC, with a resolution of 0.04 L (0.01 gal).
• For the digital IPC, when the fuel level is above 18.5 gal, the IPC displays an F. For readings between 18.5-2.5 gal, whole gallon/liter numbers are displayed. When the fuel level reaches 3.0 gal the message FUEL LEVEL LOW is displayed on the driver message center. When the fuel level reaches 2.5 gal, the IPC displays an E. When the fuel level is 1.2 gal or below the IPC displays a flashing E.
• For the analog IPC, when the fuel level is above 18.5 gal, the fuel gauge pointer is on F. When the fuel level is below 2.5 gal the fuel gauge pointer moves to E. When the fuel level is below 3.0 gal the IPC displays a FUEL LEVEL LOW message.
If the updates are not received or a communication error is detected, the IPC performs the following actions:
• For the digital IPC, the fuel gauge is dashed.
• For the analog IPC, the fuel gauge pointer moves to E.

Fuel Gage Inaccurate or Inoperative
Circuit Description
The IPC monitors the fuel level sent by the PZM through the class 2 serial data line. The IPC software controls one of the following two gauge types:
• A digital gauge consisting if a two-digit numeric seven-segment display
• An analog gauge consisting of a needle pointer.
The IPC interpolates and scales the fuel level information that the IPC receives from the PZM.
When you operate the vehicle in diagnostic mode, either in the vehicle diagnostic system or with a scan tool connected, the fuel signal supplied to the IPC is not filtered by the PZM. The unfiltered fuel signal causes the IPC to show real time readings and may be mistaken as an erratic fuel level display.
Diagnostic Aids
Connect a scan tool to the DLC.

Fatal error code 173:
This error indicates that the Image Drum Up/Down Process is not working properly. The errors are as follows:
140 - Yellow Drum Up/Down error
141 - Magenta Drum Up/Down error
142 - Cyan Drum Up/Down error
Solution:
1. Reseat the Image Drums. Ensure they are in seating properly into the drum carriage.
2. Reseat the Toner Cartridges. Ensure they are seating properly into the Image Drums.
3. Reseat the Contact Sensor Spring assembly and inspect it for damage or mis-alignment. If the springs appear bent or dis-lodged reseat them.

Hello.

Try resetting the printer:

1. Power on printer while holding both the "+" & "-" buttons simultaneously; release when "OKIUSER" is displayed.
2. Press either the "+" or "-" button until "ENGINE DIAG MODE" is displayed; press "Enter" and "DIAGNOSTIC MODE xx.xx.xx" will be displayed.
3. Press and hold both the "-" & "On-line" buttons simultaneously until "ENG DIAG LEVEL2" is displayed.
4. Press either the "+" or "-" button until "CONSUMABLE COUNTER SET" is displayed, press "Enter" to go in the menu to set various consumables.
5. Press either the "+" or "-" buttons to go to the desired consumable and press "Enter": the last digit of the count will start flashing.
6. Press "Cancel" 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.
7. Once the count is at the level you desire, press and hold the "On-line", "Cancel", and "Back" buttons simultaneously until the "*" reappears next to the count; consumable's count has been reseted to the number specified.
8. Press the "+" or "-" buttons to move to the next consumable and repeat at step 5.
9. Once all consumable counts have been set to desired amounts that are below their end-of-life thresholds, use the "Back", "+", and "-" buttons to exit through the menus (reverse of steps 2 through 4) until "INITIALIZING" is displayed.
10. Turn off the printer and turn on.

Hope this helps.

A 'print spooler' is a range of memory either internal to the printer (sometimes called 'buffer memory') or set aside from the RAM in your system. A fatal error normally means the material you tried to print has been lost and must be sent to the printer again. If the error continues to show up, you may have bad printer memory or perhaps the driver software in your system has gotten stepped on by the operating system and needs to be reinstalled. Windows loves trashing files to keep life exciting.
This problem is not related to the drum or toner cartridge.

A cyclic redundancy check (CRC error) is an error checking program that is used to verify data and can be caused by hardware or software. The most common causes are bad CD disk, hard drive or memory. To run diagnostics press and hold the <Fn> key while powering the system on. This will run the Dell Diagnostics. Examine the Windows CD and see if there are any scratches or smudges on the media, try another CD disk if you have one.

To get the OKI C5500 to keep going (without opening and closing the lid constantly) in spite of toner cartridge & drum life messages:

1) Turn off printer.
2) Hold down "+" and "-" buttons at the same time, and keep them held down while turning printer back on... continue to hold until the word "OKIUSER" appears.
3) Use "-" button to scroll down to "FUSE KEEP MODE".
4) Press "Enter" button, hold for approx. 10 seconds, then release.
5) Press "Enter" button again, followed by rapid release and repress with hold for approx. 10 seconds.
6) Release "Enter" button, then press and let up one more time quickly.
7) You will see "INITIALING" and then "ONLINE" messages.

If you currently have an error message for toner cartridge life, the message will continue to be shown until after you've sent one print job, and then it will usually disappear for awhile. It will stay gone for longer if you have your printer set up so the toner sensor is turned off.

If you currently have a error message for drum life, it will continue to appear, but you will still be able to print.

Beware that you will have to keep a closer eye on print quality (since you are no longer relying on error message to tell you when your toner cartridges are in need of a replacement or refill, or the drum truly needs to be changed or refurbished).
Please note that anytime you turn the printer off, you will have to go through the whole process again when you turn it back on. It doesn't take long though, and will quickly become habit whenever turning on your printer for the day!
Good Luck.

That is a fuser erron code. Abnormal temperature. You will need to replace the fuser. Sometimes I have sen a buildup of toner on the thermistor. If you can get to it. You can try to clean the toner off. Be careful. Very hot.

I’m happy to help further over the phone at https://www.6ya.com/expert/jayw_0e86fb055a7b73de
