Troubleshooting Resources
To effectively tackle common issues with the HP LaserJet M775z, it is crucial to reference the dedicated troubleshooting manuals designed for the HP LaserJet Enterprise 700 color MFP series. These manuals cover various models, including the M775dn, M775f, M775z, and more, and provide comprehensive guidance on resolving technical problems. The manuals outline step-by-step instructions for troubleshooting different issues, allowing users to gain a better understanding of their printer’s functionality and limitations. Users can download these manuals online, such as this troubleshooting manual or this alternative guide.
Color Printing and Job Handling Issues
One of the most frequent problems users face with the M775z involves color printing. Often, these issues arise when the printer is not utilizing the correct HP driver. Default printer drivers, such as PCL6, may not support color printing effectively. To avoid this limitation, it is essential to manually select the appropriate HP driver in the printer settings. Additionally, users may encounter difficulties with print jobs not being deleted after printing. Adjusting job settings from “stored job” to “personal job” within the printer preferences can help resolve this problem, ensuring smooth workflow.

Network and Power Issues
Network connectivity can significantly impact the performance of the HP LaserJet M775z. Users may experience printing delays or error messages due to connectivity issues, which can stem from interruptions in the network environment. Additionally, if the control panel displays a blank screen, this often indicates a power supply problem. To troubleshoot, users should check the power cable connection, ensure the printer is powered on, and confirm that the line voltage is suitable for the printer’s configuration.

Paper Handling and Sensor Errors
Another common issue with the M775z involves paper handling, particularly during the fuser delivery process. The fuser delivery sensor may fail to detect the trailing edge of the paper within the specified time, leading to misprints and paper jams. To mitigate this problem, it is crucial to regularly clean and maintain the printer’s components. Ensuring that the paper used is compatible with the printer specifications can also reduce the likelihood of such errors. For more details related to sensor issues, check the documentation in the troubleshooting manual.
Printing from Incorrect Tray
Some users might find that their HP LaserJet M775z is not printing from the expected tray. This issue often arises from the printer using an emulation driver, such as the HP LaserJet II, which may lack support for specific features like tray selection and duplexing. To remedy this, users should ensure they are using the proper driver that fully supports all printer functionalities.
