How to Identify and Fix Common Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced technical support :

If your printer`s status displays “Printer in error state,” there may be a problem with the printer itself. Make sure the printer is turned on and connected to your PC by Wi-Fi or cable. Check it for low paper or ink, and be sure the cover isn`t open and the paper isn`t jammed.
Make sure that both your computer and your Lexmark printer are connected to your network. Restart your printer. In some cases, a simple restart can fix the issue. Unplug the printer and check if there is any paper stuck in the machine, and if the toner is installed correctly.
Remove and Re-Add Your Printer in Windows

If this happens, go to Settings > Devices > Printers & Scanners, select your printer, and remove it. Then click Add a Printer or Scanner to re-add it to the device list.

Restart your printer, router, and mobile device

Restart all devices to clear network and hardware error states. Turn off the printer, and then turn it on again. Disconnect the power cable from the router, wait ten seconds, reconnect the cable, and then wait for the internet connection to complete.

Every printer contains an IP address that allows it to seamlessly connect to your computer (or other devices) through your Wi-Fi network.
1. Paper Jams. Paper jams are a common problem for printers, resulting in time-consuming and frustrating delays. It can occur when loose sheets of paper get stuck in the rollers or feeding mechanism of the printer.
Power the printer off. Leave the printer powered off for at least one minute. Power the printer back on. If powering the printer off and on clears the error, continue using the printer but keep an eye on it to see if any printhead errors return.
You may face the “printer not activated error code –20/30” for different reasons. For instance, the outdated Windows OS, incorrectly working printer drivers, or not having the fill permissions of your account may lead to this issue. Besides, this error may also be caused when your printer device is not set as default.
After replacing all the items in the maintenance kit, reset the maintenance counter: 1 Press and hold the Select and Return buttons while you turn the printer on. 2 Release the buttons when Performing Self Test appears on the display.

Lexmark X4650 paper Jamming!!
ANSWER : Well I had two printers that had similar issues – misalignment of paper feed which rendered both printers useless. I shook the Lexmark x4650 a couple of times and then plugged it in and got new paper and voila the misalignment was gone and it actually fed paper like it used to and printed it too.

Lexmark paper feed problems
ANSWER : On my X204n Lexmark laser printer, it was doing the same thing you described – basically sounded like it was trying to pick up the paper from the tray and then failing after several seconds. When you’d open the paper tray, the paper looked like it had been partially taken up with some black scuff marks on the paper that lined up with the rollers that take up the paper. I inspected the rollers and although they looked a bit smooth and worn, didn’t seem like they should be a problem. However, this particular model has just a rubber tire almost like a car tire – the rubber can come off the hard plastic wheel on the inner portion. So I popped off the two rubber “tires”, turned them inside out and put them back on. When turned inside out, the rubber looked nice and … rubbery and had a lot more grippy feeling to them. The very first printing attempt after that and the paper sucked up perfectly with no problems. I think the problem is solved! So if you have similar “tires” that take up the paper, try flipping them and see if it works for you too.

Lexmark X466 empty tray
ANSWER : The “Load Tray 1 with A4 paper” means the printer is looking for A4 size paper in Tray 1 and that is not what it is detecting. You need to make sure that the paper size that is in the tray matches what the printer is expecting so it understands that it should be looking for a specific size of paper. If you are printing on regular Letter size paper – set the printer tray to Letter instead of A4 and message should go away.
