Replaced black ink cartridge and printer keeps asking to replace

If the it's a remanufactured cartridge (not genuine), the printer will not detect the ink in the cartridge.
If it's genuine, you might want to give Lexmark's technical support a call to have the cartridge replaced.

Hi there Error 50c

Can only gave it a try.

Regarding the Dell A940 "Error 50c"....the user guide doesn't seem to mention "Error 50c". They do, however, mention a "Cartridge Error" on page 52 of the manual. They claim this means that the printer has detected a short circuit (fuse/resister) in the cartridge. As you may or may not have noticed in the manual, this is what they recommend doing about it:

1) Press Power to turn the printer off.

2) Lift the printer cover/lid (scanner unit) until the scanner support holds it open.

3) Turn the printer on.
The ink cartridge carrier moves and stops at the loading position unless the printer is busy.

4) Remove the color ink cartridge.

5) Lower the printer (scanner unit) until it is completely closed.
If the error message displays again, replace the black cartridge with a new black cartridge.

If the error message does not display, repeat steps 1–3 and then go to step 6.

6) Reinstall the color cartridge and remove the black ink cartridge.

7) Lower the printer (scanner unit) until it is completely closed.

If the error message displays again, replace the color cartridge with a new
color cartridge.
If there is no error message (indicated by flashing lights), repeat steps 1–3 and then reinstall both ink cartridges.
8) Lower the printer (scanner unit) until it is completely closed.

If you get the error message again, while both cartridges are installed, replace both of the cartridges.

Basically, what they want you to determine is,....if the short circuit is with the "black ink" cartridge or the "color ink" cartridge and then replace the cartridge that has the problem.

You may have to buy a new cartrige.
Please all I ask is call back and just gave a vote, it will gave me some satisfaction to know am helping some one, so I will keep on helping.

Try

Resetting the Ink Counter When an ink tank is replaced, the ink counter must be reset. The low ink warning is only displayed properly if the ink counter is reset.

Message Prompting Confirmation of Ink Tank Replacement
If an ink tank is removed, the printer will output a message prompting you to confirm replacement of the ink tank at the start of the next print job.
When an ink tank has been replaced, follow the procedure below to reset the ink counter. The low ink warning is only displayed properly if the ink counter is reset.
Important
If infrared communication is performed in Windows XP or Windows 2000, the printer will not output the message asking for confirmation of ink tank replacement.
Reset the ink counter from the printer driver when you replace the ink tank.

1 Check the message, and click Yes.

Note
Mistakenly clicking No instead, will prevent the low ink warning from functioning properly. If this happens, be sure to open the driver's Properties dialog box and manually reset the ink tank counter in the Maintenance tab.


2 Select the replaced ink tank, and click OK.
The dialog box allows you to select the replaced ink tank.
When both black and color ink tanks have been replaced, select both Black and Color.
If you have not replaced the ink tank with a new one, click Cancel.

Resetting the Ink Counter in Printer Properties dialog box

1 Open the Printer Properties dialog box and click the Maintenance tab.
2 Click Ink Counter Reset.
3 Select the newly installed ink tank, then click OK.

I want to print in black only and have changed the properties to grayscale, but it still won't let me print in black only. The magenta is out and it says I must replace, but i don't want color! help!

Have you tried

1. Taking out all the cartridges
2. Power down the power
3. Power up the printer
4. Open the scanner Cover
5. Close the scanner cover
6. Message will ask you to put the ink.
7. Put in Black
8. Close scanner cover
9. It may ask you whether the Black is being changed.
10. Open the cover.
11. Install Cyan.
12. Repeat step 8-10 for the rest of the 2 colours.
13. It should resolve the Black ink empty message.

Let us know if this works.

Thank you.
