printer not recognised after waking up from sleep mode

[JooneO]

on waking up from Sleep Mode my 9730e OfficeJet Pro is no longer recognised by my iMac. I have to switch the printer off, wait a minute, then switch back on to get it recognised again. This is obviously time consuming and presumably not good for the printer. I only have 5, 10 or 15 minute options for Sleep Mode, so I cannot even turn this off - which might have helped solve this problem?

@JooneO, Welcome to the HP Support Community!  

Thanks for reaching out about your query regarding your printer! 

We're thrilled to have the opportunity to assist you and provide a solution.  

This issue often occurs due to the printer losing connection with the Mac after waking from sleep mode. Here are some troubleshooting steps to resolve it:

Update Printer Firmware & macOS

• Ensure your HP OfficeJet Pro 9730e firmware is up to date.
  • Go to HP Smart App > Printer Settings > Advanced Settings > Printer Updates
• Check if macOS Monterey (12.0) is updated to the latest version.

Reset Printing System on macOS

1. Go to System Preferences > Printers & Scanners
2. Right-click (or Ctrl + Click) on your printer and select Reset Printing System
3. Re-add the printer using the + button

Change Printer Connection Type

If using Wi-Fi, switch to USB or Ethernet (if possible) to check if the issue persists.

Assign a Static IP (For Network Printers)

1. Open HP Smart App or type printer’s IP Address in a web browser
2. Navigate to Network Settings > Manual IP Configuration
3. Assign a Static IP

Modify Sleep Settings (If Available)

Some HP printers allow sleep mode to be adjusted via EWS (Embedded Web Server):

1. Open a web browser and enter the printer’s IP address
2. Go to Settings > Power Management
3. Try changing the sleep timeout settings

Reinstall HP Drivers

• Remove existing HP software:
  • Go to Applications > HP folder > Run HP Uninstaller
• Download & Install the latest HP Easy Start & drivers from HP website

If the problem persists, let me know if the printer is USB, Wi-Fi, or Ethernet connected, and I’ll refine the troubleshooting! 🚀  

Take care, and have an amazing day!
