We have followed the instructions that came with the printer but when we put in the password for the wifi, it does not connect to the Internet.

You have to take off the clear strip of plastic over the copper area, or the printer will not detect it. There should be a green pull-tab on the cartridge.

Same problem with me.
So:
I openede the whole box ( 4 screws ) in the corners. Then I presed the tiny belt on the left side to its socket, cleaned the contacts of the cartridges (56,57) with water and made them dry.

Then I reched the position of the small door which is ment to be opened once you wnat to replace the cartridge.

After this the printer works again.

SOURCE: ink cartridge problem! The following ink cartridges appear to be missing or damaged.

Solution :
1. clean the ink cartridge contacts both in the printer and the cartridge with a lint free cloth or a cotton swab. and try inserting the ink cartridges again. if it wont work proceed to step 2.
2. unplug the power cord at the back of the printer
3. press and hold # and 3 keys at the same time and plug the power cord back in. Do not release the two keys. wait until the printer would say "partial nvram reset" or anything that says "reset". if this still would not resolve the problem
4. do the same process as 2 & 3 but instead of # and 3 try # and 6. instead of saying "partial nvram reset" it should say "semi-full nvram reset". and if it would not work better go to an onsite technician. but if your printer if brand new return it to the retailer and exchange it. but before you do that try calling HP technician they would instruct you to the things i have given you. Just tell them what you have had done and asked them to replace the ink cartridges. This are the informations the agent would ask you about the ink cartridge
part number and also the expiration date.
try to ask for a replacement first if it would not resolve it. then go to a technician. I could not assure you that a technician could fix it because i have troubleshoot this kind of problems and there are alot of printer parts that needs to be fixed. Usually i suggest my clients to buy a new printer instead

Dear, this is basically an auto generated message based on system registery keys, if you want to bypass the message, then there are two ways.

1. put another cartridge in the printer and try to print, after than install the previous (original) cateridge, this will doge the printer as a new cateridge, you problem will be removed. but if you don't have another similar cateridge at hand then follow the step 2 given below.

2. Uninstall the driver, unplug the printer, restart the system and reinstall the printer dirver again, your problem will be removed.

Best regards.

Try to get your printer to recognize the new cartridge; go to start - printer and faxes -right click on printer - preferences (printing preferences) -settings -load factory settings. Print test page Ctrl+P

Please post if that worked.
