My printer does not print after I just put new cartridges in printer.

please open the door of printer and push the cartridge slowly and then the cartridge push down, the cartridge come out.repeat this same process to insert new ink cartridge.

You have a cartridge problem.

This condition is typically caused by one of the cartridges failing. Try removing the black cartridge and printing (not copying) a test page. If this prints at near normal speed the black cartridge is at fault and should be replaced. If the printer still prints slowly then put the black cartridge back in and remove the color cartridge, then print a page. Replacing the cartridge that causes the slow printing with a fresh cartridge will resolve the issue.

Inkjet printers do not like being left unused.
The color print head may be blocked. Try several deep cleaning of the print head to see if it can clear the blocked print nozzles.
If none of this works then the print head needs to be replaced. A new cartridge will not solve this problem.
NOTE the print head is not a cheap item, you may consider putting the money towards a new and better printer.

I think your printer can print with only one cartridge. Try removing the color cartridge and see if it works.

The printer need both cartridges inside it to printing.Put old color cartridge, new black and press and hold the resume button for 5 seconds.

HP put chips in there cartridges to stop you from interchanging cartridges from printer to printer.

hi there,
try to access the dell all in one center. there's a link there that says maintenance. there's an option that says clean to fix horizontal streaks.
then try to print again.
if still same. try to remove the color ink. remove the power cable of the printer. using a clean cloth, wipe the contacts of the copper strip inside the color cartridge carrier where you put the color cartridge. also clean the copper strip of the color cartridge.
then try to print again.
if still same. try to uninstall/reinstall the printer driver.
if still same. 3 points of failure
1. cartridge problem again. most probably bad cartridge batch 2. printer driver issue. 3. printer itself.

Check if you have removed cartridge protection tab from color cartridge. see MANUAL for assistance. If removed try to find you printer must have COLOR to B/W switch. Check if color light is on. If it printed test page and it wasn't color you may not installed cartridge correctly.

To prevent damage to the print cartridge, minimize its exposure to direct light. Cover theprint cartridge with a sheet of paper.
1.Open the print cartridge door, and remove the old print cartridge. See the recyclinginformation inside the print cartridge box.
CAUTION

2.Remove the new print cartridge from the packaging, and gently rock the print cartridgefrom front to back to distribute the toner evenly inside the cartridge.
3.Pull the tab until all the tape is removed from the print cartridge. Put the tab in the printcartridge box to return for recycling.
4.Insert the new print cartridge in the printer, making sure that the print cartridge is inposition. Close the print cartridge door.
CAUTION
If toner gets on your clothing, wipe it off with a dry cloth and wash the clothing in cold water.
Hot water sets toner into the fabric
