How do I replace printhead? - HP Officejet 6700 Premium E-All-In-One Printer

The carriage does not accept one or more of the printheads. Typical causes are dirty contacts on the printheads or carriage, defective printhead(s), or a defective carriage.
If parts are replaced or fixed in any of the steps listed below, attempt to verify printer functionality by turning the printer on and printing internal test prints. If functionality is verified, no additional parts should be replaced.

1. Turn the printer on.
2. Allow printer to complete initialization.
3. With the printhead icon highlighted, press ENTER.
4. Select Replace Printheads and press ENTER.
5. If the message "Printheads still functional" appears, select Yes to continue testing the printheads.
6. Open the top cover.
7. Open the carriage cover and remove all of the printheads.
8. Turn the printer off.
9. Clean the electrical contacts on the carriage and the printheads using a lint-free cloth dampened with water.
10. (for this step I suggest using the erraser on the back of a regular pencil instead of a cloth and water)
11. Allow the contacts to dry.
12. Reinstall the printheads and close the carriage cover.
13. Close the top cover.
14. Turn the printer on and attempt to verify functionality, as instructed in Step 19.
15. If the error reappears, replace the affected printhead(s).

NOTE: If the printhead error icon is a question mark, each printhead will have to be tested separately, as the printer is not sure which printhead is causing the problem.
1. Following replacement of the suspect printhead(s), attempt to verify functionality (Step 19).
2. If the problem persists following, replace the carriage and trailing cable (refer to pages 8-36 to 8-46 of the service manual).
3. Following replacement, turn the printer on.
4. Make sure the printhead alignment completes successfully and that no error messages appear on the front panel.
5. Print a troubleshooting plot (as instructed below) to ensure the print quality is acceptable.
   1. On the front panel, select the printer icon and press ENTER.
   2. Select Utilities and press ENTER.
   3. Press the UP and ENTER buttons simultaneously.
   4. Select Yes to enter the Service Menu.
   5. Select Service Utilities and press ENTER.
   6. Print pages 1, 2, 3, 4 and 5 to prove printer functionality.

Pull out the printhead from the computer and check the date under "warranty ends" If the warranty period did not lapse, call HP technical support and tell them about the problem. They will replace the printhead for free. I have gone through 3 black/yellow printheads and I received the replacement printheads via FedEx within 1-2 days. They will send you a pre-paid envelope to return via U.S. Postal Service via US Postal Service.

If the Warranty date on the printhead expired, then you may have to come out of pocket to replace the printhead since HP will argue that they are not obligated to replace the printhead since the manufacturer warranty lapsed.

If this is the case, check to see when you purchased the printer. If the purchase was within a year, the retailer (i.e. Best Buy) is on the hook since there is a 1 year implied warranty on products such as printers, regardless of whether the expiration date on the HP printhead expired.

Hope this helps

Printheads are very sensitive and HP sets a "Time" limit of about two years for # 11 printheads regardless of how much you print. ( This is bunk from HP of course!.) But the prinheads do not expire!! They just show their health and that the printhead has exceeded the warraty period ( regardless of how much you print) .

Remove the printheads from their socket and fill a 8- 12" dish with 1/4" high of warm water. Set the printheads in the water in the same position they are set in the printer (vertical) You may need to place a wooden spoon of a block behind the printheads to keep the heads in position, as they will tilt backwards.
Leave the printheads to soak for about 15minutes.
Remove the printheads and slightly press them on a folded kitchen paper towel .It should show two lines of the same color of the printhead (cyan, yellow, etc) If the two lines are not of the same length (about 1/2" long) then repeat the soaking for that color. Be sure to dry the printheads properly

Install the printheads in the printer socket vertically so the contacts are properly set.. If not you may get a message to "Install (color) printhead". reset it again and run at least 15 pages with color information. It should print ok!!
If any print heads is damaged then the only option is to replace it with a new one.
It may be that the ink line from the cartridge to the printhead is clogged and ink is not flowing. This may require to run a large print job of about 50 or so pages to force ink into the clean printheads.

The terminal strip behind the printhead that makes contact with the pins in the printer are very delicate and if removed two to three times may not make a good contact and render the printhead unuseable.

Good Luck!!

Dear palia1234,
Blinking in orange 5 times indicates that the printhead error occurs. You need to replace the printhead with a new one. But be careful before replacing the printhead, check your printhead if any smoke smell or indication of short circuitry present. Replacing the printhead in this case will harm new printhead. You'd better to take your printer to the nearest service center.

Regards,

try this link : I followed the directions and fixed the problem. the instructions that came with the new printhead weren't really complete.

Here's essentially all I did for my fix - Opened the printer top, turned the printer off. Removed the "bad" printhead, cleaned the metal contacts on the printhead and printer with windex. Closed the printer. Turned it on. waited for it to reset. Opened the printer. Turned the printer off again. Installed the printhead. Closed the lid. Plugged the printer in again. When it was ready I accessed the HP toolbox and alligned the printheads and cleaned the printheads. It worked. Here's a link with photos.

I don't just change the printheads, go to utilities and recover printheads.
If all printheads are playing up, che3ck the magenta cleaner, if it's over full it can cause all printheads to fail, this info was taken from a page on the HP web page, but ?I can't remeber where.
