I have ordered the suggested ink, but the printer doesn' t work with it

[Sönam]

I have the recommended ink (304) but the printer says "incompatible".

I already took the printer off, but it didn't help.

Hi @Sönam,

Welcome to the HP Support Community.
 

Thank you for posting your query. I will be glad to help you.

I understand your HP OfficeJet 2620 is showing “incompatible” even though you're using HP 304 ink; the issue is likely due to a cartridge model mismatch, because HP 304 is not compatible with the OfficeJet 2620.

The HP OfficeJet 2620 is designed to work with:

 
What You Can Do:

1. Check the Region of Your Printer

• HP printers are region-locked for cartridges.
• If your printer was purchased in a region that uses HP 61, it will not accept HP 304, even if they look similar.

2. Buy the Correct Cartridge

• For HP OfficeJet 2620, use:
  • HP 61 Black Ink Cartridge
  • HP 61 Tri-color Ink Cartridge

3. If You Moved Countries

• If you relocated and now only have access to HP 304, you can request a region reset
   

I hope this helps.

Take care and have a good day.
