Photosmart 7520 All-in-one error message requires restart

[Knorkator]

Printer error code 07789c, I believe. It is hard to read because it is up for just one second or so.

Printer is on standby and when it gets a orint command the display says: There is an error. Turn printer off, then on.

I clean the print head as er instructions and inserted new cartridges. Usually wireless printing work if I turn the printer off and then on but sometimes a docuemnt gets stuck in the queue and I have to restart the print spooler. I tried the scan and print doctor as well as the HP Support Assistant. The latter installed some updated and fixed an unkown Port issue. The problem persists. Very inconvenient.

Any help is appreciated

Thank you for posting on HP Forums, 

Riddle_Decipher is at your service. 

As I understand the Printer error code 07789c shows up shortly before the printer restarts on its own,

Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details: 

Did you ensure genuine HP Ink cartridges are being used?

Have you reset the printer?

While you respond to that, here's what you need to do:

Step 1: Use genuine HP ink cartridges

HP recommends that you use genuine HP ink or toner supplies. HP cannot guarantee the quality or reliability of non-HP or refilled cartridges. If you do not use genuine HP cartridges, the steps in this document might not resolve the issue. To check the authenticity of your cartridges, go to hp.com/go/anticounterfeit.

Visit HP SureSupply to check ink or toner cartridge compatibility or purchase replacement cartridges and other supplies.

1. Go to HP SureSupply.

2. If necessary, select your country/region.

   Figure : Country/region selector

   

3. Follow the on-screen instructions to order new supplies or check cartridge compatibility with your printer.

You can also purchase genuine HP cartridges and supplies from other retailers.

If the issue persists, continue to the next step.

Step 2: Reset the printer

In some cases, a printer reset can clear the error message.

1. Turn the printer on, if it is not already on.

2. Wait until the printer is idle and silent before you continue.

3. With the printer turned on, disconnect the power cord from the rear of the printer.

4. Unplug the power cord from the wall outlet.

5. Wait at least 60 seconds.

6. Plug the power cord back into the wall outlet.

      NOTE:

   HP recommends connecting the printer power cord directly to the wall outlet.

7. Reconnect the power cord to the rear of the printer.

8. Turn on the printer, if it does not automatically turn on.

   The printer might go through a warm-up period. The printer lights might flash, and the carriage might move.

9. Wait until the warm-up period finishes and your printer is idle and silent before you proceed.

If the issue persists, continue to the next step.

Step 3: Check estimated ink levels

The error might be caused by a low or empty ink cartridge. If an Ink Alert message displayed before the error occurred, replacing the ink cartridge(s) might resolve the issue.

Thanks for the tips. Cartridges are all new and original HP cartridges. The reset tip did the trick, though. Funny, since I had tried that before. Anway, probem solved. Thanks
