HP LaserJet M402n Driver, Supply Memory Error, Network Printing Failures, and Tray Configuration Issues
The HP LaserJet M402n driver enables communication between the printer and networked systems for print job processing. When printing stops, settings change unexpectedly, or devices appear online but fail to print, the driver is often suspected, but many cases are tied to HP M402n supply memory error, network port configuration issues, or print job settings mismatches rather than a driver fault.
This page provides HP LaserJet M402n driver context together with troubleshooting notes describing situations where HP M402n not printing from one computer, HP M402n WSD port printing issues, or HP M402n keeps asking for Tray 1 occur despite repeated driver reinstalls.
Problem: HP LaserJet M402n “Supply memory error” prevents printing
What users observed: The printer refused to print and displayed a HP M402n supply memory error, even though the toner cartridge was installed and appeared normal.
What was tried: The toner cartridge was removed and reseated, and attention was given to the contact points between the cartridge and the printer.
Where this sometimes ended: After reseating and cleaning the cartridge contacts, the printer resumed printing. The issue appeared tied to cartridge communication rather than a driver failure.
Problem: HP LaserJet M402n One workstation cannot print while others can
What users observed: A specific M402n would not print from one nearby workstation, while the same printer worked consistently from other computers on the same network.
What was tried: Repeated removal and reinstallation of the printer and drivers, including registry cleanup and testing multiple driver versions.
Where this sometimes ended: After a factory reset of the printer and another full removal and reinstall cycle, printing began working again. It was not clear which step actually resolved the issue.
Problem: HP LaserJet M402n Intermittent network printing failures across multiple units
What users observed: Several M402n printers on the same network would stop printing intermittently. They remained reachable by IP and their web interfaces loaded normally, but print jobs failed.
What was tried: Temporary fixes included rebooting printers, rebooting the print server, and changing the port assigned to the queue.
What this turned out to be: A network port configuration issue (WSD vs TCP/IP) rather than firmware or driver instability.
Where this sometimes ended: Printers using WSD ports were unreliable. Switching to standard TCP/IP ports stabilized printing, while other printers on the same subnet were unaffected.
Problem: HP LaserJet M402n Printer repeatedly asks to load Tray 1 and pauses between pages
What users observed: Each page triggered a prompt to load Tray 1 or press OK. The printer paused between pages, making multi-page jobs extremely slow.
What was tried: Print job settings were reviewed before sending documents.
Where this sometimes ended: When the job’s media type and size matched the tray settings, the delays stopped. The printer behavior was tied to job configuration rather than hardware failure.
Problem: HP LaserJet M402n Printers suddenly switch to manual duplexing
What users observed: Multiple M402n printers began prompting for manual duplexing even though duplexing was supposed to be disabled and had worked correctly the day before.
What was tried: Cold resets and verification of printer-side settings showed no obvious changes.
Where this sometimes ended: Manual duplexing was enabled in print server preferences. Turning it off restored normal single-sided printing.
Problem: HP LaserJet M402n Setup installer cannot find the printer on the network
What users observed: The printer responded to pings and its web interface was accessible, but the setup utility could not detect it.
What was tried: Restarting the printer and changing its IP address had no effect.
What this turned out to be: The wrong installer for the M402 variant was used.
Where this sometimes ended: Using the installer that matched the correct M402 series variant allowed detection to succeed. The printer itself had never been offline.
Across HP LaserJet M402n troubleshooting reports, the recurring pattern is that HP M402n supply memory error, HP M402n not printing from one computer, and HP M402n WSD port printing issues are not caused by driver failure. Printing issues are typically tied to consumable communication, network port configuration, or print job settings, rather than the driver itself.
