Lexmark Printer Not Printing? A 7-Step Cost-Smart Checklist to Run Before Calling a Service Tech

When a Lexmark printer stops printing in the middle of the workday, most offices react one of two ways: open an IT ticket or call a service company. I have approved both responses. As the person who manages printer and supply spending for a 170-person education company, roughly $31,000 a year across hardware, toner cartridges, and repairs, I am also the one who reviews the invoices afterward. Neither response is wrong. But both get expensive when the real problem was a paper jam, a stuck print queue, or a toner cartridge the printer no longer recognizes.

Here's the thing: most 'Lexmark printer not printing' cases are not hardware failures. At least not the expensive kind. The checklist below starts with the free fixes and works toward the ones that cost money. It is written for standard office laser printers and MFPs. If you are troubleshooting a photo printer, stop following this list; that is a different set of drivers, print heads, and paper problems. For a business Lexmark unit, run these seven checks in order.

The 7-Step Lexmark 'Not Printing' Checklist

Step 1: Look at the printer's display before you touch a computer

The operator panel usually tells you exactly what is wrong. 'Paper jam in tray 2.' 'Replace toner cartridge.' 'Front door open.' Clear the jam, close the door, or replace the cartridge before you go anywhere near the print driver. I know that sounds obvious, but the first time one of our machines stopped because someone left the rear door ajar, two departments spent nearly an hour trying to reconnect to it before someone noticed the blinking message on the screen.

If the display says 'toner very low,' the printer may finish the current job and then refuse the next one. Do not call support yet. Get a cartridge, install it, and see whether the message clears.

Step 2: Print a configuration page straight from the printer

Once the visible errors are gone, print a settings or demo page from the printer itself. On most Lexmark MFPs, the path is Settings > Reports > Print Demo Page, but the menu names vary by model. This one step separates printer hardware from every other possible cause. If the configuration page prints, the printer engine can print. The problem is upstream: a driver on one computer, a network connection, or something stuck in the queue. If the configuration page does not print, the problem is physical, such as toner, the imaging unit, or the paper path.

Either way, you just saved yourself from reinstalling a driver that was never broken. Write down the IP address on that page before closing the report menu; you may need it in Step 4.

Step 3: Reseat or replace the toner cartridge (the step people skip)

Toner problems cause no-print issues even when the display does not say 'replace toner.' A cartridge can sit slightly loose, have a dirty chip contact, or simply be old enough that the printer stops trusting it. Open the front cover, remove the cartridge, inspect the contacts, and reseat it until it locks into place. Close the cover and let the printer finish its initialization cycle. If the printer says 'cartridge not recognized,' power cycle the printer once before you order a replacement.

This is also where buying decisions show up. I am not against compatible toner cartridges in every situation. But I have seen a cheap compatible unit throw a 'cartridge not recognized' error and stop a shared printer for half a day. In that scenario, the genuine Lexmark cartridge was actually the cheaper option. When you search for Lexmark printer toner cartridges, compare cost per page rather than shelf price and verify the exact part number for your model.

Step 4: Check whether the printer is still reachable on the network

Here is a scenario that shows up in our support log every few months: the printer works fine for weeks, then one morning every workstation says 'printer offline.' The printer is usually fine. The IP address changed overnight. Printers commonly use DHCP, and when the lease renews, the device can pick up a different address. The drivers on people's computers are still sending jobs to the old address.

If your configuration page printed in Step 2, take the IP address from that page and type it into a web browser. If the Lexmark web page opens, the printer is alive. Then check whether the driver port on the users' computers points to that same address. For any printer that more than a few people use, set a static IP or a DHCP reservation so the problem does not come back after every lease renewal.

Step 5: Clear the print queue and restart the spooler

A single stuck job can silently block everything behind it. When that happens, users click Print again, which adds more jobs to the pile. The fastest clean fix is to open Windows Services, find Print Spooler, and restart it. Yes, it clears the queue. People will need to resubmit their documents.

Tell the office before you restart the spooler. Otherwise, everyone who hit Print in the last 30 minutes is going to hit it again. That is how a five-minute fix turns into six copies of the same 20-page proposal. Not that I am speaking from experience.

Step 6: Update the Lexmark driver and firmware if the problem is intermittent

If the printer drops jobs occasionally, works for three days, then stops again, and the toner, network, and queue all check out, try a driver and firmware update before you call in paid help. Networked printers get software updates on a regular basis now. In Q2 2024, one of our MFPs started dropping jobs after a Windows update. The local service quote was $160. The fix was a 15-minute driver and firmware update from Lexmark's support site. I cannot promise every case will be that easy, but the software update is a lot cheaper than the service visit.

Step 7: Spend 10 minutes on the procurement review after it prints again

Once the printer is back online, figure out why it stopped in the first place. Did the toner run out because nobody acted on the low-toner warning? Did someone install a cartridge from an untested source? Is this printer busy enough that a high-yield cartridge would make more sense than a standard one?

When you order Lexmark toner cartridges, the number that matters is cost per page: the price divided by the manufacturer's page yield, not the sticker price. Compare two or three resellers for the same part number. And track printer supplies in one budget category. If a design team's art supplies go through a different purchasing process than printer cartridges, you will keep missing the real cost of printed projects.

Common Mistakes That Turn a 10-Minute Fix Into a Costly One

Three patterns show up again and again in our cost reports:

• Calling for service before the printer prints a configuration page. If the machine cannot print its own settings page, you may genuinely need a technician. If it can print that page, the machine is not dead; keep checking the network and queue before you spend money.
• Buying toner in a panic. When you wait until the printer is empty, you pay for expedited shipping, accept whatever vendor has stock, and skip the cost-per-page comparison. Panic buying is how supply budgets leak.
• Treating printer repairs like it is still 2020. The basics have not changed: paper, toner, network path, queue. But the execution has. Printers are network devices, and firmware and driver maintenance are normal parts of running a fleet. Some issues need a technician. A growing number do not.

Run the checklist in order the next time a Lexmark printer is not printing. Most of the checks take less than five minutes, and the expensive fix usually ends up being the last one you try, not the first.

If the printer is still not printing after all seven checks, then a service visit is justified. But by then you will know exactly what the printer can and cannot do, which makes the technician's job faster, the diagnosis clearer, and the invoice easier to approve.
