My hp photosmart c4385 all in one says the ink cartridge is not in but they both are

SOURCE: HP PHOTOSMART C4280 PRINTER WONT READ INK CARTRIDGE.

The cartridge is not seated properly and/or the contacts are dirty. Use a cotton swab with rubbing alcohol and gently clean both the copper contacts on the cartridge and inside the cartridge socket. Allow several minutes to dry and then try again.

Hi,

With reference to Expert Burti, he has given the solution to your problem.

"Just got off the phone to HP and the issue is resolved *phew*. This waswhat I was told to do for my C5180. First they told me to do a powerdrain. This is done by pulling out the power cable and then holding theon/off button for a minute, then putting the power cable back in (this didn't work).
Then we did a master reset. Unplug the printer, then pressing the help and ok buttons simultaneously plug it back in. This sorted it. :
Have to say it looked like this whole process used up shed loads ofink, so by the time I had finished I needed to replace 3 cartridges!
HP were pretty good and were very willing to send out a new printer if the reset didn't work (as the printer is still in warrenty). Hope you get yours sorted too."

With thanks from expert Burti.

Excuse me--but I would like hp to have a look at this series and come out with a statement.

I did call someone in computer repair i think he said they cannot fix it (I don't remember that part)--but (this I do recall) that it probably needed a sensor to be replaced.

I have another bone to pick with hp--revealing: I did use the quick set up format and did not watch any dvd s on it if they gave them--

one thing I've guessed from all of this--there are several colors that get used up awfully fast, and yellow is one of them--even when we have our default set for black. double check yourselves: I believe that their nice black is created with yellow and other colors as well as the black cartridge.

Since I cannot say whether this was revealed in any of the handouts or an instructional video, if there was one--I don't know that they didn't tell this outright.

To be truly user friendly--I don't think that sort of information should be so buried that a casual user wouldn't know that.

(Sure it makes what they more impressive if you don't know how they do it, but I'd like to think they want us to choose easily what colors we are using, especially when printing 'black' ink!)

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

SOURCE: How do you install the ink cartridges?

With the printer on, pull down the cartridge door (the front section above the paper tray). This puts the carriage on the right hand side. Remove the tape from the new cartridge without touching the copper area. With the HP logo up, push the cartridge slightly down and forward until it snaps in. The color cartridge goes in the left slot and the black goes on the right. Push firmly to ensure the cartridge is fully in place. Close the cover and press OK in response to the onscreen prompts. (Confirm installation and then align the cartridge.) If the test page come out correctly press OK at the status page (in the LCD menus).
