@claire12345, Welcome to HP Support Community,

Thank you for posting your query; I’m here to help by guiding you through steps to resolve this issue

Check for a Newer Firmware Update

Sometimes HP releases another update that resolves compatibility issues.

• Go to HP’s support website
• Enter your printer model: HP OfficeJet Pro 8035
• Check if a newer firmware update is available.

Disable HP Cartridge Protection

If your printer is rejecting cartridges after a firmware update, it may have enabled HP Cartridge Protection:

• Open the HP Smart App or access the printer's Embedded Web Server (EWS):
  • Find your printer’s IP address (Menu → Settings → Network Settings).
  • Enter the IP address in a web browser.
• Navigate to Settings → Printer Preferences → Cartridge Protection.
• Disable Cartridge Protection, then restart the printer.

Try Rolling Back the Firmware

HP does not provide official firmware downgrades, but you can try:

• Check if an older firmware version is available:
  • Search online for HP OfficeJet Pro 8035 older firmware .
  • Ensure it’s from a trusted source to avoid security risks.

Prevent Future Updates

If you manage to revert the firmware, disable automatic updates to prevent the issue from happening again:

• HP Smart App → Printer Settings → Disable Firmware Updates
• EWS → Printer Update Settings → Disable Automatic Updates
