I have a HP 2542 printer that uses a HP61 black cartridge and I have purchased two that will not fit in the printer. The reason is that the new cartridges are physically different than the old ones. They have a different length on the face than the ones I have been using. Why have you changed the length? I can provide scans if needed. Please advise what to do..

Hi @DVDhunter,
Welcome to the HP Support Community!
Thanks for reaching out about your query regarding your printer!
We're thrilled to have the opportunity to assist you and provide a solution.
It sounds like you are experiencing an issue with the compatibility of HP 61 black ink cartridges for your HP 2542 printer. Normally, HP maintains the dimensions of ink cartridges to ensure compatibility. However, there may be instances where specific batches can have discrepancies in size due to manufacturing errors or other factors.
Here's what you can do:
Double-check the cartridge model: Ensure that the cartridges you purchased are indeed HP61 cartridges. They might be mislabeled or incorrectly shelved if purchased from a retailer.
Confirm compatibility: Make sure the HP 2542 printer supports the exact cartridge model you are trying to insert.
Examine packaging for errors: Ensure that the packaging or product description doesn’t list any physical changes in the cartridge that could affect compatibility.
I hope this helps.
