Large format HP Officejet 7500 a: print head for my large Format HP Officejet 7500 a


I have a printer of e-all-in-one large Format HP Officejet 7500 a - product E910a No.: C9309A serial no: [personal information deleted]

I need to replace the print head.

I found this on HP page they said it use the CN643A

On a support HP cat, what they said use CN642A.

On another page of HP, they said use CH638A.

The CN642A is now 5 HP564 ink cartridges, but still the HP web page said that it will work in my HP Officejet 7500 a large format using the HP920 cartridge.

I found other heads of printing on the web article CD868-30001 model number and on the web page of HP were unable to match the part number for a list of available models.

Now my big question including the number of pieces to the correct print to my printer head?


I offer my apologies. It should have been if your printer uses 4 ink cartridges, type CN643A

Please click HERE to access the document to see what print head fits into your printer.

Check under Solution 4: replace the print head.

Step 2: Order the print head

He states:

If your printer uses 4 ink cartridges, type CN643A

If your printer uses 5 ink cartridges, type CN642A

Please ignore my previous post where I suggested CN642A.

  • New print head for V715w?

    Anyway is to buy a new printhead for Dell's Dell V715w printer (or someone else)? The current print head is therefore nothing good, I have about $ 150 of ink on the spot and I would use it.  I can't believe that Dell does not place a small piece of plastic/silicone and expects me to just buy a new printer.



    We found that the price of a print head is the price of a new printer. If the printer is under warranty, contact Dell.

    If this isn't the case, then try these procedures.

  • Which current HP printers (Photosmart?) have removable print heads for cleaning?

    After my 6515 Photosmart suffered a premature death due to a clogged printhead black, I did a lot of research to know what to buy to replace.

    I looked at other brands, too, and unfortunately, there aren't has no easy answers anywhere.

    I feel that I am more familiar with HP, not to mention the offer of 564 papers of ink and photo that I always have on hand.

    Are there current Photosmart printers who have the leverage that allows you to easily remove the printhead to clean if it clog?

    I would really like to find that point, but so far, having this option is not in one of the specs I've seen.

    I would not be able to print photos, so it would be good if there is a Photosmart printer that this option was.

    Thanks for your help!

    Photosmart 7525 has removable heads, it is basically the same model as the Photosmart 7520 sold elsewhere.

    Are you an error on the printer on the print head, callieco?



    I've been a user of products HP 10-12 years now. I prefer to buy HP products for its service, but it is really not what is expected of the HP India.

    I was to find a print head for my HP 7500 has which was purchased in April 2012 to beyond 60-70 days, but in vain. None of the centres of HP to Mumbai service seem to have it. We prefer to buy HP products because its parts/spare parts are readily available, given the scope of the India of HP in the market.

    This availability not made me rethink my trust I had in HP.

    Location: Mumbai, Maharashtra, India.

    Please consider this as urgent and please solve my problem as soon as possible.

    Hoping for the best answer.

    Kind regards

  • Alignment of printer heads, failed to 7680

    The two print heads (HP88) have been replaced today. C/M that works very well. The K/Y seems pretty faulty. My K/Y Printhead and ink cartridges are HP brand. After completing the installation of the print heads, the window of the printer showed "alignment failed". So I ran the alignment and line tools. Still have the same error. Print only C/M.

    The Self Test diagnostic page reads for the health of the print head: good. Date at the end of the 2014-03-26 warranty and installation 2012-07-15

    I tried pluggin and unplugging the printheads. I ran the clean print heads (used too much ink). Still no black or yellow printed ink.

    I ran the utility Mac HP program and health of the print head for the B/Y now says "Fair"... It's strange how what he says good about an hour ago (it should because it's new).

    Any suggestions on what I should do?

    Mac Pro, OS 10.6.8 20 GB of ram

    HP printhead passable health utility

    Two hours later, after swapping in old (in order or return B/Y printhead to the dealer), I also get both GOOD. But it will not print black or yellow. The alignment still does not work. Don't see the magenta lines.

    Now it's back to the FAIR. It's really frustrating. I'll just pack.

    I had to show this. Now TWO new heads are BAD

    I should have done this in the first place: I just called HP technical support and the gentleman said HP can't even stand the 7680 more and the printer is probably dead. It's that old (bought in 2007). He offered to the extended 8600 Officejet more a strongly reduced guaranteed new of 3 years with free return shipping on exchanges in the my (now deceased) 7680. I'm happy to keep that thing out of landfill. Now, I must return this second set of printheads.

    Although I'm bummed to get rid of the 7680, I am impressed by the HP support to take into account the factor of the v3 and the disappointment of customers. They did everything quite transparent and somewhat painless. .

  • my print head large format 7500 needs?

    My 7500 has large format officejet displays the message "ink cartridge seems to be missing or damaged.  I cleaned second level clean print heads, put in a new hp black cartridge, clean the plates of copper brass on the cartridge and the printer.  do I have to replace the print head?

    I understand that you are looking to replace the print head after doing the different troubleshooting steps, but I would like to clean the print head manual too. Here a link to the user manual. It will show how to clean the print head and what materials to use on pages 120-125. While you clean the contacts on the print head after you delete it, check to see what warranty end date to the printhead is. If this date has not passed, I would call into HP total care for quality output troubleshooting.

    I would also do a hard reset of the machine to try to clear the error message and return the printer to a known working state. No user settings are lost with a hard reset.

    1. with the printer plugged directly into a wall outlet and turned on, unplug the power cord from the back of the printer.
    2 then unplug the power cord from the wall outlet.
    3. wait at least 30-60 seconds
    4. plug the power cord into the wall outlet first. If a module with the power cord, make sure that the light of the module and then reconnect power cord on the back of the printer
    5. the printer should power back on by itself, but if not use the power button on front panel to turn on machine.
