Printers are susceptible to technical glitches or malfunctions and all of them can quickly be solved by easy problem-solving methods at home. In addition, the vendors offer comprehensive instructions in the manual included with the device on troubleshooting printer problems. In certain instances, the instructions may be obtained and retrieved online, by entering the printer error code. It's easier to move them to the authorized service center in cases when you can't repair them yourself. Instructions on how to repair printer issues after a power outage are given below. Read and understand the tips before using them.
Solution 1.
When you have a wireless printer, the printer is always offline because it disrupts communication following a power failure. In this scenario, you can continue by restarting the wireless router and resetting the firewall. After the wireless router is disabled, the network is restarted to bring it back operational with the wireless printer. This will work normally so you can do the first thing before all other choices.
Solution 2.
If the network reboot didn't fix the off-line printer problem, the network configuration might be a problem and you should try to reconfigure it. It may be when you have been reconfigured because that is normal because there are many users of printers.
To restart the printer, locate the Control Panel device, and press Network Setup on it. Now, click Reset Network Settings and select Yes from your confirmation tab. Afterward, print a configuration file, test to validate the original restored network setting and then restart the printer. Go to the printer panel and check configurations until restarting the printer. This choice opens a new window with a chosen Wireless Setup screen, then tap on to the Wi-Fi Protected Setup option or the Wireless Setup Wizard, and follows the directions to complete the procedure. When these measures are done, try attaching the printer again to figure out if it is connected or not.
Solution 3.
You could attempt to switch off the SNM mechanism if the previous choice did not work out. To that purpose, open the Control Panel, pick Devices and Printers, choose and right-click on your printer. Click the Properties print on the chart, pick the Ports tab in the window that will appear next, and press Set Button. Enable and uncheck SNM status, click OK, and exit. It will uninstall the SNM protocol to see if the printer is back online.
These are solutions that fix an offline printer error and check whether it works normally.
