What This Error Means

Lexmark Error 68 typically indicates a problem with the printer's internal configuration, non-volatile memory (NVRAM), or communication between its main components.

Detailed Explanation

Lexmark Error 68 is a general internal error code that points to a disruption in the printer's core operations. It often signifies that the printer's non-volatile random-access memory (NVRAM), which stores critical settings like network configurations, calibration data, and usage counters, has become corrupted or is failing. This corruption can occur due to sudden power fluctuations, firmware update failures, or simply the aging of the NVRAM chip itself. Alternatively, Error 68 can also signal a more general communication breakdown between the printer's main control board (engine board) and other vital components, such as the fuser, formatter board, or even specific sensors. When this error appears, the printer usually stops all operations and displays the code, preventing any further printing. Because it's an internal system error, it's less about a physical jam or consumable issue and more about the printer's 'brain' not functioning correctly. While sometimes a simple reset can clear temporary glitches, persistent Error 68 often suggests a more fundamental hardware problem that might require deeper diagnostics or component replacement.

DIY Troubleshooting Steps

Try these steps before calling a specialist

1
Turn off the printer completely, unplug it from the wall outlet, wait for at least 60 seconds, then plug it back in and power it on. This performs a hard reset.
2
If the printer has a removable power cord at the back, ensure it is securely seated in the printer's power port.
3
Disconnect any USB or Ethernet cables from the printer. If the error clears, reconnect them one by one to identify if an external connection is causing interference.
4
If the printer has an accessible NVRAM or system board reset button (check your specific model's service manual if comfortable), attempt a factory reset. Be aware this will erase all custom settings.
5
Ensure the printer's firmware is up to date. If you can access the printer's menu or web interface, check for available updates and install them. A corrupted or outdated firmware can sometimes trigger internal errors.
6
Remove and re-seat all accessible internal components like memory modules, formatter board, or any other user-serviceable cards, ensuring they are firmly connected.
7
If the printer has a maintenance kit, ensure all components (fuser, transfer roller, etc.) are correctly installed and seated. Though less common for Error 68, a poorly seated component can sometimes cause communication issues.
8
Try printing a simple internal test page (if the printer allows it before the error appears) to see if the error is triggered by specific print jobs or general operation.

When to Call a Specialist

You should call a specialist if, after attempting all the DIY steps, the Lexmark Error 68 persists. This error often points to a failing main control board (engine board), formatter board, or a corrupted NVRAM chip that requires specialized tools and expertise to diagnose and replace. If the printer is still under warranty, contact Lexmark support immediately. For out-of-warranty printers, a technician can perform advanced diagnostics to pinpoint the exact failing component, which might involve replacing expensive internal parts.
