How to check if the cartridge or the sensor is the problem

Here are some steps I feel you can take to resolve the issue with your Kyocera KM-C2525E yellow cartridge:

Check the cartridge chip - The yellow cartridge has a small chip on it that communicates with the printer. If the chip is damaged or dirty, it can prevent the cartridge from being recognized by the printer. Try cleaning the chip with a soft, dry cloth and reinserting the cartridge.

Check the cartridge contacts on the printer - The printer also has contacts where the cartridge is inserted. If these contacts are dirty or damaged, it can prevent the cartridge from being recognized. Try cleaning the contacts with a soft, dry cloth.

Perform a drum refresh - The drum in the printer can sometimes become coated with toner, which can prevent the cartridge from making proper contact with the printer. Try performing a drum refresh from the printer's control panel to clean the drum.

Reset the printer - Sometimes resetting the printer can clear any issues with the cartridge recognition. Try turning off the printer, unplugging it from the power source, and waiting a few minutes before plugging it back in and turning it on.

Replace the cartridge sensor - If none of the above steps resolve the issue, it could be due to a faulty cartridge sensor. The sensor detects when a cartridge is inserted and communicates with the printer. You may need to replace the sensor to resolve the issue.

That is a miss reading of the toner density sensor. Which is located in the developer unit Replace the sensor or dv unit. Also check the connection of the unit to the copier and the harness from the sensor to the dv unit.

try foll:

1.U r using wrong cartridge model or faulty -cross check.
2. Lock of the cartrdige broken,Check the same which presses crtridge sensor at back.
3 Cartridge Sensor at the back broken or faulty

> Switch off the machine, remove power cord,> remove right,left & back doors,> see the snap shot observe sensor & spring> clean the sensor from dust > check spring dislocated? fix it properly, ensure that sensor flag maintain its home position> insert/remove cartridge,observe sensor flag moving properly > Power on the machine, check.. OK?,

If your Lexmark printer is displaying the message "replace toner clean printer," and you have already checked that the toner is full, there might be an issue with the toner cartridge or the printer's sensors. Here are some steps you can take to troubleshoot and potentially resolve the problem:

1. Remove and Reinsert Toner Cartridge: Turn off the printer and open the front cover to access the toner cartridge. Carefully remove the toner cartridge and then reinsert it firmly into the printer. Make sure it is seated correctly in its slot.
2. Check for Obstructions: Inspect the printer's interior for any paper jams, debris, or other obstructions that might be interfering with the toner cartridge or the printer's sensors.
3. Check Toner Sensor: The printer has sensors that detect the toner level. Sometimes, these sensors can become dirty or malfunction. Locate the toner sensor (usually a small window or sensor on the toner cartridge) and ensure it is clean and not obstructed.
4. Reset Printer: Turn off the printer, unplug it from the power source, and wait for a minute or two. Plug the printer back in and turn it on again. This can sometimes clear temporary errors.
5. Check Toner Cartridge Contacts: Ensure that the contacts on the toner cartridge and inside the printer (where the toner cartridge makes contact) are clean and free from dirt or toner residue.
6. Check Printer Settings: Verify that the printer settings are correctly set to recognize the installed toner cartridge. If the printer allows you to manually set the toner cartridge type, make sure it matches the actual cartridge installed.
7. Update Firmware: Check if there are any firmware updates available for your Lexmark printer. Updating the printer's firmware may address known issues and improve printer performance.
8. Try a Different Toner Cartridge: If you have access to another compatible toner cartridge, try using it in the printer to see if the issue is specific to the current cartridge.

your printer ink cartridge can not access (move to middle) when you open up the cover, you may try
1) try to open right side cover you move the cartridge by hand (power off) to middle position, then take out the cartridge and reinstall it then power on, the cartridge moving right, you may open up the cover again if the cartridge go back the middle position which means your printer works normal. still stop moving go next
2) check the cartridge initcial sensor at righe side, the cartridge moving to the end of right should be touch this sensor, find out it and check there is good touch (click) by the cartridge body. adjust the sensor position maybe needed.
3) cartridge is stucked sometime also check the cartridge moving rail hard moving, need to drop oil to lubricate.

there are 4 or 5 sensors through paper road:
1)paper input sensor near input roller
2)margin sensor between input roller and cartridge unit
3)transfer bell sensor between cartridge and fuser unit
4)fusing sensor before fusing
5)out put tray sensor
check all sensors if you can find out and check any paper jam there and check sensor stander at normal position, also check each sensor click ok(the micro switch ok) .
there is any sensor out of work should be showing paper jam.

sorry I got it, usually you may try:
1) check all paper road no paper inside include the area betweem input tray and cartridge unit the area wetween cartridge and fuser unit and output tray.
2) check 4 sensor input sensor near the input tray roller, marging sensor between input roller and cartridge unit, cartridge sensor at oneside of cartridge unit body, fuser sensor near fuser roller. usually need to clean or adjustment the position.
3) check input roller and cartridge unit and fuser unit at running condition when the power on.
anyone nothing running show error light blink, also show the hardware trouble if all sensors are normal.

Hi usually sensor of cartridge unit fail which send a wrong signal.
you may try:
1)take out cartridge unit looking carefully a tiny switch
at one side with a smal metal stander or a plastic button(you may hear click sound) just check this sensor position and adjust to normal where the sensor can active by the cartridge. put back cartridge test, do next if still not detect.
2) try to take out this sensor or check it's cable wire connection and using meter test, should be connect when click.

Pls check in foll order: A.replace with another cartridge. B clean the contact points on the cartridge and the cartridge holder. c.check wheteher the carriage is stuck or too hard ,then oil the rod a bit. D.Please check whether the plastic portion of the carriage wher the cartridge rests may not have broken ? E.The carriage cable may have got cut . f.the carriage sensor might have gone,Please replace the carrriage cable with sensor.. Happy Faxing Omnipresent
