4. Maintenance
4.1 Replacing Toner Cartridges
When print quality degrades or the printer indicates low toner, it's time to replace the toner cartridges. The HP Color LaserJet Pro M154NW uses HP 204A (Black, Cyan, Yellow, Magenta) or HP 205A (Black, Cyan, Yellow, Magenta) LaserJet Toner Cartridges.

4.2 Cleaning the Printer
Regularly clean the exterior of the printer with a soft, damp cloth. Refer to the full user manual for instructions on cleaning internal components if print quality issues persist.
5. Troubleshooting
5.1 Power Issues
If the printer does not power on, ensure the power cord is securely connected to both the printer and a working electrical outlet. Check the power switch on the back of the printer. The HP Auto-On/Auto-Off Technology helps save energy by turning your printer on only when needed, so a brief delay before it becomes active is normal.
5.2 Print Quality Problems
Poor print quality can often be resolved by ensuring the toner cartridges are properly installed and by gently shaking them to redistribute toner. If issues persist, check for any obstructions in the paper path or consult the printer's internal diagnostics.
5.3 Connectivity Issues
For network or wireless connectivity problems, verify that the printer is connected to the correct network. Restart your router, printer, and computer/mobile device. Ensure the printer's Wi-Fi is enabled and configured correctly. The HP Smart App can assist with network setup and diagnostics.
