HP L7680 Print Head Problem

After I started using remanufactured ink cartridges, I began to get the error message "problem with Print Heads K/Y and M/C" To fix the problem I have to remove the print heads, reinsert the print heads, run "clean print head" and "align print head." This seems to solve the problem for a while, then the error message "problem with Print Heads K/Y and MC" comes back again. Am I having this problem because I'm using remanufactured ink cartridges?

Sometimes the circuit strip that sits at the back of the printhead carriage is the problem due to moisture, ink soiling, etc...

To clean these you need some cotton buds (like you use to clean your ears) and gently clean the area at the back of the printhead carriage (where the printheads slot into).

This removes any ink, or moisture that could be causing a short circuit or similar.

I do not know how to change my printhead on my HP Officejet Pro L7580


---Make sure the printer is on, or press the Power button to turn it on. Wait for the printer to finish any warm-up diagnostics or print jobs it is performing.

---Open the access cover to the print heads. This cover may be the top cover, the front door or an ink access door on the front of the printer.

---Wait for the cartridge carriage to stop moving, making sure it is completely stationary before putting your hand in the printer. Lift up any clips or latches keeping the print heads or cartridges in place.

---Remove the old print head or ink cartridge if it is part of the cartridge, and discard it. Remove the packaging from the new print head, making sure to peel off any protective tape or twist-off protective caps.
---Insert the new print head or cartridge into the empty slot. Lower any clips or latches and make sure the print head or cartridge does not wiggle in its spot, otherwise you need to pull it out and reinsert it into the printer.

---Close the cover you opened to access the print heads and wait for the printer to calibrate the new print heads. Some printers may produce an alignment page, which you can throw away.

False ink empty


Are you sure its exclamation mark?..
This warning message related to print head. (warn out). When you are replacing ink tube assembly use dummy print heads to do the priming (new ink tubes are empty & they have to fill with ink)..
Action: Remove all cartridges and print heads, switch on the printer follow the screen message.(Insert cartridges first next dummy print heads).once its recognizes cartridges then it switch over to print heads,insert dummy print heads. Once printer recognized the dummy print heads, printer will perform priming, during priming dummy print heads will filled with respective inks.(follow the display message)Remove dummy print heads & insert normal print heads. Wait till printer recognizes print heads, load the paper & wait till performs the calibration, once calibration is successfully done issue closed.
If calibration not successfully done, check align print out for which print head is not printed properly, replace it..
Pl ensure that minimum 50% ink levels required in cartridges before performing the priming. Best of luck..

My hp dj9000s printer is switched off since 6 month, now I switch on it shown error message for Lc, Lm ink cartridge. (cartridge is ok I replace with new one but error is same)


If an inkjet printer has not been used for some time and several print head deep cleaning has been done and it still does not print properly then the nozzles in the print head are blocked.
Inkjet printers need to be used frequently to prevent nozzles blocking with dried ink.
You need to replace the print head to get the printer functioning again.
But these print heads are expensive to replace, it may be better to buy a better and a later model printer for not much more costs.

HP all-in-one not printing cyan color


Place a soft clean tissue paper over the cartridge print head and leave for about eight minutes. You can secure it with the aid of a rubber band. It should be held firm ok. If the tissue paper is not dampened by ink then the cartridge would have gone bad or the ink dried. You also know that they have expiry date and could go bad while yet in the packaging b/c it has expired. Good luck

HP L7680 Print Heads need real cleaning!


If the ink has dried up in the nozzles try putting a wet cloth in the microwave to get it hot enough to produce a little steam and set the cartridge, nozzles down on the damp cloth until ink starts to ooze from the cartridge. May require a couple of tries. Try using the cleaning program again.

Be careful not to touch the copper contacts on the cartridges.

HP L7580 Printer Head Problem??


I had the same problem plus had problems with message indicating "alignment failed" and to monitor the blakc/yellow print head.  The print quality was very bad in black.  It seemed to print about 1.5 lines and then skip a line. When I replaced black and yellow it seemed to get better print quality was just as bad.  Finally called HP support. These are the steps they told me to do.

 

1. disconnect power

2. remove all ink cartridges

3. remove and clean contacts of both print heads

4. perform simultaneously the following press 6 and # on the keypad while at the same time plug in the power.

5.  --- the printer came on (black squares on the screen) and then shut off.

6. --- was told to power up the printer

7. Printer began checking device(took a long time)

8. Printer began aligning printer (took a long time)

9. Finally finished = Message on screen "Alignment Failed"

10. Still not printing and hours later.

11. They will be replacing printer

12. Then they hit you with that you should buy a set of inkjet cartidges from them at $109.96 -  warranty 2yr, works better, etc.

13. Sent to somebody else to arrange shipping new printer.

14. Free shipping 5-7 days - big deal -  placed my work (home office) on hold.

16.  Service help - listen when it follows the script, otherwise like talking to a door  (In India).

17. Finally get transfered to somebody else and he informs me that he is not authorize to give me a new printer, need to talk to somebody else who is not there.  Advises to call during business hours.  He said that he could request that I be called back but that it could take a 1.5 days to get back to me.

18. I am going to call tomorrow morning during business hours - wish me luck.

 

I don't know what is awaiting but IN The Future I will not talk to anybody from INDIA - they do not have authority and do not listen (but maybe they don't listen because they can't do anything about it).

 

Good Luck!!
