prevent auto shut down

[cmd3]

I've seen past forums regarding the issue of this unit automatically shutting down after prest number of hours.  Is anyone aware of a solution yet to the problem of not being able to wake the printer up again without manually turning it back on?  Or is there a way to prevent it from shutting down altogether?

Hello @cmd3,

Welcome to the HP Forums.

I would be happy to help you with your HP LaserJet Pro MFP M277dw. I understand that your printer goes offline Issue.
I would like to help you resolve this issue.

Reset the printer

1. Make sure the printer is idle, not making any sounds, before continuing.

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

3. Unplug the power cord from the wall outlet.

4. Wait at least 60 seconds.

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

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

7. If the printer does not turn on by itself, press the Power button  to turn it on.

 Remove multiple printers from the printer list

1. Search the Mac for Print, and then click Print & Fax, Print & Scan, or Printers & Scanners in the list of results.

2. Find the printer names that match your printer from the list of devices.

   Figure : Printers and Scanner window with multiple names of a printer in the list

   

3. If you see multiple printer queues for the same printer, remove all extra printers by selecting them one at a time, and then clicking the minus button  at the bottom of the list. Leave one 'idle' printer in the list that matches your printer if available and use this printer as the Default printer.

4. Try printing again.

Reset the printing system

1. Right-click (or Ctrl + click) the blank space in the Printers list, and then click Reset printing system....

   Figure : Resetting the print system

   

2. Click Reset in the confirmation window.

3. Enter the administrator user name and password, and then click OK.

4. Wait until the printing system is reset and no devices show in the Printers list.

5. Add your printer to the list again as was done previously.

6. Try printing again.

Let me know how it goes.

Cheers.
