HI @MM1966,

Welcome to HP Support Community.

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

The error code "77.02.07" on an HP OfficeJet Pro 8135E printer indicates a problem with the printer's internal hardware or firmware. Here are some steps you can take to troubleshoot and resolve this error:

Power Cycle the Printer: Turn off the printer, disconnect the power cord from the rear of the printer, and wait for about 60 seconds. Then reconnect the power cord and turn on the printer. This will perform a basic reset of the printer's hardware.

Update Printer Firmware: Check if there are any firmware updates available for your HP OfficeJet Pro 8135E printer. Firmware updates can often address bugs and improve overall performance. You can usually check for updates through the printer's control panel or the HP Smart app.

Check for Paper Jams or Obstructions: Open the printer's front and rear access panels and check for any paper jams or obstructions in the paper path. Clear any jams or obstructions that you find, and then close the access panels securely.

Inspect Ink Cartridges: Open the ink cartridge access door and ensure that all ink cartridges are properly installed and seated correctly. Remove and reseat the cartridges if necessary.

Perform a Hard Reset: If the error persists, try performing a hard reset on the printer. This involves resetting the printer to its factory defaults. Refer to your printer's user manual or HP's support website for instructions on how to perform a hard reset.

I hope this helps.

Take care and have a good day.
