Communication troubleshooting
Please follow these suggestions to diagnose remote communication issues.
General troubleshooting
1. Check the following symptoms:
●
The front-panel display does not show the Printing message when an image has been sent to the
printer.
●
The computer displays an error message instead of printing.
●
The computer or printer hangs (stays idle), while communication is taking place.
●
The printed output shows random or inexplicable errors (misplaced lines, partial graphics, etc.).
2. To solve a communication problem:
●
Ensure that the correct printer has been selected in the application.
●
Ensure that the printer works correctly when printing from other applications.
●
Remember that very large prints may take some time to receive, process, and print.
●
If the printer is connected to a network, check the printer connectivity status: the printer should
have an IP address and it should match the IP address specied in the printing computer. If the
addresses do not match, then congure it correctly; if the issue persists, check the network
conguration.
●
Try WiFi.
●
If the printer is connected to a wireless network, try moving the printer closer to the wireless
router. Alternatively, try connecting the printer by network.
●
If the printer is connected to a wireless network, you can request a diagnostic report from the front
panel: Scroll down the dashboard and press , then scroll down the menu and press Network Set Up
> Print Reports >.Wireless Test Report. Alternatively, try moving the printer closer to the wireless
router, or try connecting the printer by wired network.
When a network device automatically congures itself by receiving an IP address from the DHCP service,
this IP address may change from the last time the device is powered o to the next time it is powered
on, which may lead to the device being shown as "oine" when driver port settings are congured with
the original IP address. There are at least three possible ways to avoid this:
●
Increase the lease time of the DHCP server device.
●
Set a xed IP address for the printer so that it will not change by DHCP.
●
Congure the printer and driver to refer to the hostname instead of the numeric IP address.
Wired network issues
▲
If the HP software provided with the printer cannot be installed, check that:
●
All cable connections to the computer and the printer are secure.
●
The network is operational and the network hub is turned on.
