Scheduler shutting down due to program error

[bettina123]

HI! 

I juts bought my HP Deskjet 2335 printer and have successfully installed it (i think) already. I've tried copying BW & Colored and it works. so i know that ive installed the cartridges properly. 

Now, i cant print / scan a document. I've uninstalled and reinstalled the printer and even updated my OS to the latest version of HIgh Sierra. 

I went to the errors log and saw this 

E [21/Oct/2020:20:47:41 +0800] Scheduler shutting down due to program error.

Thank you for posting on the HP Support Community.

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

• Does your printer Turn Off Unexpectedly or Repeatedly?

If the printer is plugged into a power strip or surge protector, the printer might not be getting enough power to properly function. To resolve the issue, plug the printer into a wall outlet.

Update the printer firmware for printers connected to a Mac.

1. Make sure the printer is on and connected to the computer through your local network or USB cable.

2. Go to HP Customer Support - Software and Driver Downloads.

3. If a Let's identify your product to get started page displays, click Printer.

4. Type your printer model number, and then click Submit.

   The software results page for your printer displays with the default operating system selected.

5. If you need to change the version of macOS or OS X, click Change, select your version, and then click Change.

6. Click Firmware, and then click Download.

   If a Firmware section is not listed, an update is not currently available for your printer.

7. When the download is complete, open the [Printer_name].dmg file.

8. Double-click HP Firmware Updater.

9. Click the name of your printer, and then click Continue.

   

10. The updater checks the firmware version installed on the printer, and then displays the results in the Update Information window.

    • If Device is ready to be reflashed displays, click Continue to update the firmware.

      When the update completes, click Done.

    • If This Firmware Updater does not contain upgrades for your device displays, the printer firmware is already updated to the most recent version. Click Cancel to exit the updater.

Hope this helps! Keep me posted for further assistance.
