Mechanism is the same for all cartridges. Some printers like HP have an index finger space on it that you press down to release. See if your cartridge has similar groove.

Remove the cartrdges and look to the top inside right of the printer. You should see 4 cut outs with sensors in that correcpond to the crtridges. Blow out these as there will be a bit of toner in there blocking the sensors. Happens quite a lot on these printers

On the right side of the machine there is a part which monitors the toners. The toner sensor board 42613601 may be dirty or defective. See #29 in the diagram
It may be something physical, too like something not fitting, etc., but generally I recommend to replace the board.

I have a four in one Lexmark x5630 printer and have replaced cartridges with brand new black and colour 36 & 37xl. The printer won't even print a test page - just says that cartridge error co


The problem could be due to a communication failure between one of the printheads (cartridges) and the All-In One (AIO) or by a short in one if the printheads. Please follow the steps below to identify and fix cartridge issues:

  1. Make sure the printer is on.
  2. Open the printer cover. The print cartridge carrier moves and stops at the loading position, unless the All-In-One is busy. Note: If the carrier does not automatically move to the center, turn off the printer or unplug the printer from the power source and then carefully slide the carrier to the center.
  3. Remove both cartridges from the carrier.
  4. Close the printer cover.
  5. Re-brick your printer by pulling out the power supply - black box behind the printer where the power cord is plugged in to, and re-plug after 30 seconds.
  6. When the printer turns on, reinsert one cartridge first. Close the printer cover and check for any errors.
  7. If no error appears, reinsert the other cartridge. Close the printer cover.
  8. Replace whichever cartridge is causing the error to appear with a new genuine Lexmark cartridge. Try to print a document again to verify that the problem is fixed.
Try to contact the store where you bought the new cartridge(s) and have them replace it. You may also contact Lexmark Technical Support Center for assistance (especially if you're using genuine cartridges).

  2. Open the printer cover, and then wait until the carriage is idle and silent.
  3. Press down gently on the top of the cartridge to release it.
  1. Figure 2: Removing the tri-color cartridgec00484998.gif
  2. Slide the cartridge out and inspect it.
    CAUTION: Do not touch the copper electrical contacts or the ink nozzles. Figure 3: Electrical contacts and nozzlesc00211537.gif 1 - Copper electrical contacts 2 - Nozzles
    • Check the electrical contacts for debris.
    • Make sure all the clear protective tape has been removed from the nozzle and electrical contact area. Figure 4: Removing the clear protective tapec00211538.gif
  3. Reinstall the cartridge in the product and try again to print.
If after you have completed these steps you are still unable to resolve the issue, go to the next step. Step two: Make sure the cartridge is compatible Which cartridges you use depends on your country or region. To check the cartridge compatibility for your product, click this link, HP SureSupply . If your language or country does not display next to the globe icon (c01906983.gif ) select your language and location.
  1. If the cartridge is compatible, reinstall it in the printer.
    • Place cartridges marked with a triangle in the left carriage slot.
    • Place cartridges marked with a square or pentagon in the right carriage slot.
    Figure 5: Print cartridges installed correctlyc01091334.jpg Figure 6: Direction to insert the print cartridgesc01091335.jpg
  2. After verifying that your cartridge is compatible, reinstall the cartridge in the product and try again to print.

  2. Remove the cartridge and place it on a piece of paper with the nozzle plate facing up.
    NOTE: If you are removing a tri-color, photo, or gray photo print cartridge, try to clean the contacts quickly enough that the cartridge is not outside of the printer for more than 30 minutes. The ink can dry and clog the nozzles if the cartridge is outside of the printer for too long.
  3. Dip a clean cotton swab in distilled water, and then squeeze it to remove most of the moisture.
  4. Clean the print cartridge contacts. Do not touch the nozzles. Figure 7: Cartridge electrical contactsc00832021.gif
  5. Clean the contacts inside the carriage, inside the printer. c00246272.gif

  2. Open the cover of the printer and remove the print cartridges.
  3. Close the cover and wait for the Insert Ink Cartridges message.
  4. Disconnect the power cord from the back of the printer and wait for one minute.
  5. Reconnect the power cord. If the printer does not automatically turn on, press the Power button.
  6. Open the cover and reinsert the print cartridges.
  7. Close the cover. If prompted, print a calibration page.
  8. Reconnect the USB cable, and try again to print.
If after you have completed these steps you are still unable to resolve the issue, go to the next step. Step five: Replace the cartridge If after you have completed these steps you are still unable to resolve the issue, replace the cartridge. If you do not have a replacement print cartridge, go to the next step. Step six: Print in backup mode If you do not have a replacement print cartridge, you can still print in ink backup mode until the issue is resolved. Remove the problem cartridge and print with the remaining cartridge.
  • If you remove the tri-color cartridge, the printouts will be in grayscale.
  • If after you have completed these steps you are still unable to resolve the issue, service the product.
  • If you remove the black or photo cartridge, the printer will print more slowly and the colors in the printouts may differ.

Usually when you open the cover the cartridge holder should move to the center that will allow you to install the cartridge. If this is not the case you could force it to move by:
  1. Opening the cover as if you're installing a new cartridge.
  2. Unplug the power cord
  3. Lift the cartridge holder enough height to allow you to slide it on to the center
  4. After sliding, you should be able to install the new cartridge.
  5. After the installation close the cover and power up your printer.

You could find the root cause by performing different steps. One of the easiest methods is that you need to make sure that the plastic protective tape which is usually used on the new black cartridge is off. Usually the user makes this mistake. This mistake might occurs due to absent-mindedness. The reason could also be some distractions which happen while loading the new black ink cartridge.

Unable to remove black cartridge, it is really stuck. Help


I just changed my black toner this past week, and finally figured out why the cartridges get stuck like this.

First, you must eject the toner cartridge on the front-panel menu:
Menu->Replace Toner->Eject Toner->Black(K)

It will say "Rotating to Black Toner(K)" and then say "Black Toner(K) Ready to Eject"

Now, open the front panel and you'll see the black toner cartridge in front. You can also open the top panel if you want more light on your work area.

Lift the lock handle on the old toner cartridge to the "unlock" position, and here's the part that the Dell instructions don't have:

There are two channels for the toner cartridges -- one on each side. Run your finger down the channel on the right, and you'll feel a small, spring-loaded catch. This catch often gets sticky and won't release the cartridge without some help. Don't force it, but gently move it towards the back of the printer and it should release.

Now the old cartrdige should slide right out, and you can finish per the instructions that came with the new cartridge.

Have you checked the ink level on the black ink cartridge? It's probably out. Or if it's a new cartridge, make sure the tape covering the connecter has been taken off.

Brpther DCP 330c does not recognise new black ink cartridge


Usually there is more than one cartridge empty when you receive this kind of problem. Try opening the top cover and check if the display changes - it should change to specify one (or more) of the color cartridges as empty. That one(s) should be changed too.

Have installed new epson black ink cartridge in c1100 printer. unable to press down locking bar on this new cartridge


Try re-inserting it again, L/H side should go in slightly ahead of the R/H. Give it a push & wiggle and it should lock in. An alternative method of fitting the cartridge is to open the top cover & remove the PCU. With the front cover shut you can rotate the cartridge "carousel" until the black is in the 2 O'clock poition when looking from the R/H side of the printer. You can now insert and lock the cartridge into place.

Please take a moment to rate this solution, thanks.
