Sometimes our printer stops working unexpectedly. If your printer is offline or appears to be offline, the answer may be as simple as you think before you include it in technical service. Let’s check out some basic symptoms if we could fix the problems by trying at least these:

Is the power on?

Check that the power button is on and the power plug is plugged into a wall outlet.

Is it sleep mode?

Occasionally the printer enters Sleep mode when it has been idle for an extended period of time. Pressing the power button again or another button that exits sleep mode may work.

Examine the printer screen for error messages

 

One of these messages may appear:

Out of ink / Refill ink
Open lid / Close lid
Paper jam
Troubleshoot the error message that is displayed.

Can it be defined as default?

Access to Control Panel >> Devices and Printers
Select the appropriate printer. Click on the printer and select “Set as default printer”
There should be a check mark at the bottom of the printer icon.
Are the drivers installed?

Usually Windows sets up a generic driver when the printer is supported, but it’s absolutely crucial to set up your company’s driver CD for the printer to function properly.

Are any duplicate printers using the exact same name installed? (Listed as “Copy 1”, “Copy 2”)

This happens when, during some events, you change the USB port on your computer and accidentally configure the drivers. Delete all copies of installed drivers, such as the device initially recorded, and uninstall the drivers. Restart the computer and reinstall the printer driver.

Is your printer connected to your computer?

Make sure the printer USB cable is firmly connected at both ends from the computer to the printer. Somewhere you may have a loose connection. Disconnect the USB cable, and then connect it.
If you are using an Ethernet cable, make sure the printer is on the router or access point.
After the printer has been set up as a wireless link, make sure the router or access point is turned on and connected to the printer.

The printer is connected but does not look below Devices and Printers

Occasionally the USB icon may appear in the system tray and the printer remains undetected OR it displays an error with the message “This device may run faster” or similar if the printer is connected to two or more USB ports. Try these alternatives:

Make sure you are not using a cheap USB port pulse or a cheap general purpose power supply (PSU). USB ports may be poorly powered if other USB ports are used by devices that need more electricity. If this is true, temporarily get rid of other USB devices from USB ports and attach to the printer first, before any other device requires a lot of power.

Avoid linking multiple printers to one USB port pulse extender as this may cause at least two printers to share on a single USB port which is only displayed as one USB icon, unless you confirm that the links have been individually detected and won’t cause later problems.

Delete all printer drivers in Control Panel >> Devices and Printers, restart the computer and reinstall the drivers. Make sure you have disabled any antivirus program or attached an exclusion to the application and allow any modification of the application before installing the drivers.

You are probably using an outdated USB printer cable for USB 1.1 devices. Swap the cable using a USB 2.0 (or USB 3.0) compliant cable.

Sometimes installing or flashing motherboard firmware from a personal computer can change settings in the computer’s BIOS. To do this, restart your computer and press the key that appears on the display, which allows you to get the BIOS. Look through the BIOS and try to find the USB mode option and set it to the highest speed or variant. Do not change other BIOS settings unless you are sure what you are doing.

In the event that the offline printer problems persist despite resolving the suggested answers, contact the nearest qualified technician to have a look.
