  • Printer telling us to replace printhead as colour are printing in "bands". Is your Genuine HP CN643A Printhead Assembly the correct one for my printer as its not on the list of compatibles printers. Serial no is CN315B2G62 Model SNPRC-1101-01 Rev D if that helps identify the correct printhead if you sell it? Thanks

    Is this the correct Printhead replacement for "HP Officejet Pro 8600 Plus"

    Thank you for your enquiry. After having a look I can see that unfortunately we do not sell any maintenance items for your printer. I am sorry that I am unable to help you with this any further.

  • Hi, please could you tell me if you stock printhead replacements for HP Officejet Pro 8620?

    HP Officejet Pro 8620 Printhead replacement

    Hi Graham, thank you for your question. Unfortunately we do not stock replacement printheads for the HP Officejet Pro 8620 e-All-in-One Printer at this time.

  • I have a HP Officejet 7500A wide format printer, the black ink has stopped working so I want to try a new printhead, will the CN643A be correct for my printer, the number on my printhead is CD868A and I can't seem to find one for this number.

    Printhead for printer

    Thank you for your question. The CN643A listed above is the correct printhead for the HP Officejet 7500A Wide Format printer. I have provided you with a link that will take you to all the items we currently stock that are guaranteed to work for your printer - https://www.cartridgesave.co.uk/ink-cartridges/HP/Officejet-7500A-Wide-Format.html

Any chance to buy a cheap replacement or repair this one? If i will buy one from you and still not working maybe because another thing can i refund the printhead back for refund? Let me know please. Thanks a lot.

    Sadly the only stocked item we list that is compatible for your printer is the genuine printhead shown above.

  • My HP 7510 will not print in black. I've tried a new cartridge, cleaned the head at two levels twice and aligned the printhead, all with no success. Is the CN643A printhead correct and will this solve the problem ? It is a five cartridge head?

    Cannot print black type on HP7510

    The CN642A is correct for your printer and does have space for five cartridges. However, I am unable to confirm whether this would resolve the printer issue for you. Usually if you require a new printhead you should get an error message on the printer to advise. It might be worth speaking to HP directly before purchasing the item.

    Answered by Vicky Lush (Staff Member) - about 2 years ago
  • HP's site showed the CN643A as the replacement print head for the Photosmart B110 printer but I note that this is not one of the models you list. Is this the correct print head?

    HP B110 printhead

    Thank you for your question. Yes this is the correct printhead for your printer.

    Answered by Joe Hemlin (Staff Member) - about 3 years ago

  • Can I use the 364XL ink cartridge in my HP Officejet 6500A Plus e-All-in-One printer?

    HP CN643A printhead compatibility

    No, this is the original HP CN643A printhead for the HP Officejet 6500A Plus e-All-in-One printer which is a different product. The Officejet 6500A Plus printer uses the HP 920XL ink cartridges. Please see: http://www.cartridgesave.co.uk/ink-cartridges/HP/Officejet-6500A-Plus-e-All-in-One.html

  • Hello, I have an OfficeJet 6500 model E709n. It's about five and half years old and has worked fine until today. It's now telling me that the printhead is missing. I've tried several different resets and it hasn't solved the problem. Hence, I 'm now considering buying a new printhead. Is the CN643A shown on your site the correct replacement part for this printer? Thanks and best regards, John Browett.

    HP CN643A printhead compatibility

    The HP Officejet 4500 Wireless All-in-One printer (E709n) is one of the printer models listed on this page as being compatible with the HP CN643A printhead assembly. Please refer to: http://www.cartridgesave.co.uk/ink-cartridges/HP/Officejet-6500-Wireless.html

    Answered by Denise Mannion (Staff Member) - about 3 years ago
  • I have an HP 6500 A Plus all-in-one printer and on the printhead that was supplied with it, the reference on the printhead is 'CD868B'. I bought one with the reference 'CD868A' from another supplier and was assured by them that it was compatible but it wasn't. Can you assure me that your product reference 'CN643A' is the same as the 'CD868B', please?

    HP CN643A printhead part number

    We can't confirm that this HP CN643A printhead is the same part as 'CD868B' as we don't recognise this as a valid UK part number. We can only guarantee that this genuine HP CN643A printhead unit is the correct part for a HP Officejet 6500A Plus e-All-in-One printer that was purchased in the UK.

    Answered by Denise Mannion (Staff Member) - about 3 years ago
  • How long do HP suggest that this item should last between changes?

    HP CN643A printhead life

    Unfortunately, HP don't specify how long the HP CN643A printhead life will be and this might depend on your usage of the printer, or even which printer model you're using the CN643A printhead for. We can only advise that the printer should prompt you when the HP CN643A printhead unit needs to be replaced. For further information we advise you to contact HP directly.

    Answered by Carla McDonald (Staff Member) - about 4 years ago
  • Do you sell printheads for HP 500 series printers. If so, what's the reference number and cost please?

    HP CN643A printhead compatibility

    This genuine HP CN643A printhead unit isn't compatible with any HP 500 series printers, it only works in the printer models listed on this page. We would need the full model name of your printer in order to advise you on which printheads fit the machine. The closest match to a HP 500 series printer we have is the Designjet 500 printer which uses HP 11 printheads. Please refer to: http://www.cartridgesave.co.uk/ink-cartridges/HP/Designjet-500.html

    Answered by Stacy Bass (Staff Member) - about 4 years ago
  • My HP 6500A will not print in black. I've tried a new cartridge, cleaned the head at two levels twice and aligned the printhead, all with no success. Is the CN643A printhead correct and will this solve the problem ? Yesterday it printed okay but no good today. If so, can this be delivered by tomorrow?

    HP 6500A printhead replacement

    We can confirm that this genuine HP CN643A printhead is the correct part for use in the HP Officejet 6500A Plus e-All-in-One printer. However, we would advise you to contact HP's technical support department for help in troubleshooting your printer to see if replacing the printhead will resolve the issue that you've encountered. If you can confirm that you need a new printhead we can deliver this replacement HP CN643A printhead assembly to you on the next day, provided that it's in stock at the time you place the order and you've ordered before our daily cut-off time.
