    I'm having the same problem: repeatedly get error message saying each cartridge is not installed although there is plenty of toner in all cartridges. I later had a "Media Jam - Fuser" error message that has now completely shut my printing capability down.

This worked for me
Each toner cartridge has a small green chip with 3 gold-colored contacts on it. First thing to try is to rub those contacts with an ordinary pencil eraser. You will need to rotate the toner carousel to get to all 4 sets of them. To get it to rotate, there is a little square-ish hole in the white plastic housing to the right of the toner cartridge that is visible when the top cover is raised. Push a pen down in the hole, which will push on a tab allowing you to rotate the toner carousel until you can see the next cartridge. Repeat for all four toner cartridges. Close up the printer, power it up, and see if it solves the problem. If not, do this: Remove the drum (gently pull on the green handle). Be careful not to touch the roller or let it contact anything. Get a flashlight, look down inside the printer on the right (it's kind of hard to see, it's almost under the toner cartridge). You will see a black sensor switch with three wire-like contacts, surrounded by a square white housing. Wipe off those contacts, if you can get the eraser in there better yet. Contacts are kind of flimsy, be VERY careful you do not bend them. Next, take the point of a pencil and push on each contact, it should move in and return when released. If that seems good, put it all back together and try the printer again.

Cartridges error on a lexmark

Error: "Invalid Toner Cartridge"; Error: "Invalid Refill"; Message: "Change Cartridge"
One of these error messages may appear on the printer display immediately after or shortly after a new toner cartridge is installed into the printer. Note: This may not be specifically a toner cartridge problem; the error may be due to a stuck cover open switch on the printer.

To see if the cover open switch is the cause of this problem, open the top front cover and observe the message on the printer's display panel. The display should read Close Door or Insert Cartridge.

If this message is not displayed, the top cover open sensor and switch will need to be replaced. In addition, the printer may have damaged the new toner cartridge. If the cover open sensor is not operating properly, a new cartridge can be incorrectly flagged as a refilled cartridge by the printer. If this happens, the new cartridge will continue to cause an Invalid Refill or Invalid Cartridge error even if you try reinstalling it or installing it into another printer. If this should occur, please contact the point of purchase of the cartridge to find out how to get the cartridge replaced.

Caution: If the cover open sensor is not operating, do not install another new toner cartridge until you have completed the directions below. Inserting another new cartridge can cause that cartridge to stop working as well. Should this situation arise, please take the following actions:

Place the original working cartridge (the empty or near-empty one) back into the printer. This should clear the error message.

Turn the printer off. Doing this will disengage the cover open sensor.

With the printer switched off, open the top lid and remove the old toner cartridge.

Now replace the old cartridge with another new Lexmark toner cartridge.

Power the printer back on. The printer should now read this cartridge as a newly installed toner cartridge and the error should be cleared. The printer and toner cartridge should function properly now, but the top cover sensor on the printer will still need to be replaced.

If your printer is still under warranty or covered under a service contract, please contact Lexmark Technical Support or your service provider for further recommendations and instructions. Until you can get the cover open switch replaced, remember to have the printer powered off whenever you replace the toner cartridge.

If the top cover switch appears to be working fine, or if you have followed the above steps and your printer continues to post an Invalid Toner Cartridge or Invalid Refill error, make sure you are using a new original Lexmark toner cartridge. A toner cartridge remanufactured or refilled by a third party can cause this error.

To help identify a refilled cartridge, look for the yellow label attached to the toner drum and the body of the toner cartridge. If this is damaged or removed, the cartridge may have been refilled.

If you are using a third-party refilled or remanufactured toner cartridge, it is recommended that you install a new Lexmark brand toner cartridge. Lexmark cannot guarantee the compatibility of any third-party toner cartridges with our printers.


1 Switch on the Lexmark X83 printer.

2 Lift open the cartridge door at the front of the device, below the scanner unit. The printer automatically moves the cartridge carrier to the correct position.

3 Pull each ink cartridge toward you to unclasp it from the carrier. Lift the cartridge out of the cartridge carrier.

4 Clean the copper contacts on the bottom of each cartridge with a clean, dry lint-free cloth. Use a gentle, circular motion to clean the contacts.

5 Insert the ink cartridges back into the cartridge carrier. Push back firmly on each cartridge until it snaps into place.

6 Repeat each step in this procedure again. Close the cartridge door.

How to solve 10.00.00 memory supply error

Memory Supply Error 10.00.00

The printer is unable to read or write to the print
cartridge e-label, or the e-label is not on the cartridge.

Basically what is happening is the printer cannot read the small chip on the toner cartridge. The chip is located on the toner cartridge as it is inserted into the printer. The probes on the E-label reader make electrical contact with the chip, which pass along information to the printer with respect to Toner Life and number of prints made etc... If the printer is unable to read the chip for any reason an error is reported. The error is common to many varieties of HP printers
1 - Make sure the toner is firmly seated into the printer.
2 - Power cycle the printer with the toner out of the printer. Install the toner back into the printer.
3 - Install another toner cartridge.
4 - Verify that the e-label connector is firmly seated in connector.

My HP is a 2500 Color Laser Printer- with an HP C9700A Black toner cartridge installed. System was working fine- Suddenly I am getting the message that there is a problem with the Black Cartridge NON-...

The cartridge has matching contacts on printer and cartridge.
The contacts connect to an internal ID chip inside the cartridge.
Clean the contacts with Servisol sprayed onto a clean cloth, or rub clean with a pencil eraser.
If this doesn't work then your ID chip may have failed.
A toner refill / service /sales center should be able to test it for you.
In case they don't have a compatible printer, and to double-check your printer for faulty electronics, lug your printer along as well.
Does this help?
Regards, Clive.

Printer is coming up with id mismatch after putting new toner cartridge in goes away when old one is put back in?

The toner for the 9035 has a 'chip' to identify the toner is correct for the 9035, ie the toner is the correct manufacturer and model.
If you are getting the "ID Mismatch" error you either;
  1. Have a faulty chip on the new toner cartridge, I guess the best option would be to go back to the supplier.
  2. The toner cartridge is a copy / refill etc and has the wrong chip fitted, again going back to the supplier would be the best option.
  3. Locate the contact for the chip on the new toner cartridge and ensure these are clean from any toner dust etc which may prevent incorrect contact with the printer.

A message keeps flashing up 231 fatal error. Can you let me know what I need to do. 0116 240 3430 Dorothy

231 fatal error is telling you that the data from the chip on the toner cartridge is invalid or cannot be read.

This may happen for one of the following reasons:

1)The printer is unable to read the data on toner chip because of toner dust or dirt inside the printer.
Solution: Clean the printer inside, clean toner slot and drum.. See:Clean your laser printer.

2)Either the toner is not an original cartridge, it is refurbished or refilled, or the chip on the toner cartridge is defective.
Solution: replace the toner, or replace the Chip on toner cartridge.

3)The toner sensor in your OKI is defective.
Solution: Call the support number listed on the printer manual to arrange repair.

I have replace the yellow colour and ever since the printer comes up with a error saying no toner

this is a very annoying error message

Konica Minolta Magicolor 2400/2500 series printer "X cartridge not installed" One of the most frustrating features of the Magicolor 2400/2500 series of printers is the very annoying X Cartridge not installed message
This error message can occur at any time with both original cartridges and or refilled cartridges. It is caused by either toner / paper dust covering either the chip on the toner cartridge or dust covering the chip sensor inside the printer. It can also be caused by a faulty chip reader inside the printer.

The printer uses a carousel to rotate the toner cartridges. Dust and toner can easily spill as the cartridges rotate. The error can appear at any time but seems to be most annoying after a paper jam or other error. It is also important to make sure that the cartridges themselves are clear of toner dust. Pay particulair attention to any copper contacts on the cartridge.

(the infamous) ?X toner not installed? error message

I just got off the phone with KM tech support for the same problem with my 2430dl.  Take out the drum and remove the toner cartridges, then look inside the printer.  You will see a piece of glass about 6" long.  Next to it, on the right side of the printer, there is a little white plastic enclosure that contains three spring-loaded contacts; this is the sensor that reads the chips on the individual cartridges.  First, try cleaning the three contacts with a swab/alcohol, as well as the chips on each cartridge.  If this doesn't solve the problem, then the problem is likely with the sensor.  The part number should be 4139-6306-02, and it runs about $5. This should solve the problem.
