While this error sounds catastrophic—manifesting as a printer that refuses to wake up, lacks the usual warm-up mechanical noises, or simply hangs on a “Processing” screen—it is a logical or physical connectivity fault that can often be resolved through methodical hardware troubleshooting. Rest assured, as a senior engineer, I can confirm that most 980.xx errors do not require a full machine replacement.
Symptoms of Lexmark Error 980.xx
When a Lexmark printer suffers from a 980-series communication failure, the symptoms are primarily digital but have physical tells. You will first notice the Control Panel Lockout: the screen will display “980.xx Service Error” (common variants include 980.01, 980.02, or 980.10) and will not respond to touch or button inputs.
📖 Pro Tip: Verify Technical Specs
Incorrect repairs can cause fire or injury. Always verify with the manufacturer’s manual.
From a mechanical standpoint, the printer will exhibit Thermal and Kinetic Stasis. Unlike a healthy boot sequence where you hear the fuser rollers turning and the cooling fans ramping up to speed, a printer with an Engine Communication Error often remains eerily silent. Because the system board cannot tell the power supply to energize the fuser, the unit stays cold. Additionally, print jobs sent from a PC will immediately hang in the queue or return a “Communication Failure” status, as the printer’s network interface cannot hand off data to the print engine.
How to Fix Lexmark Error 980.xx (Step-by-Step)
-
Perform a “Deep” Power Cycle:
Do not simply flip the power switch. Turn the printer off and unplug the power cord from the wall outlet. Press and hold the power button for 15 seconds to discharge the electrolytic capacitors on the power supply board. Let the unit sit unplugged for at least 10 minutes. This allows the volatile memory in the engine controller to reset completely. Plug it back in directly to a wall outlet (avoid power strips for this test) and check for the error. -
Enter Diagnostic Mode and Check Firmware:
If the screen allows, attempt to boot into the Diagnostic Menu (usually by holding 3 and 6 or 2 and 6 during power-up). If you can access this menu, navigate to “Printer Setup” and look for the “Flash Code” version. Often, updating the firmware via a USB thumb drive can re-flash the communication protocols and clear a logic-based 980 error.
Safety Warning: Never interrupt a firmware flash, as this can permanently “brick” the system board. -
Access the Controller Board:
If software resets fail, hardware intervention is required. Use your Phillips #2 screwdriver to remove the metal access panel (usually on the right side or rear of the machine).
Safety Warning: Ensure the printer is unplugged. Wear an ESD wrist strap grounded to the printer’s metal chassis to prevent static electricity from destroying sensitive CMOS components. -
Reseat the Interconnect Cables:
Locate the wide, flat ribbon cables (LVDS) connecting the main System Board to the Engine Board. Carefully flip the locking tabs on the connectors and pull the cables out. Inspect the gold-plated leads for any black carbon buildup or oxidation. Use compressed air to blow out the sockets. Re-insert the cables firmly, ensuring they are perfectly square in the socket, and lock the tabs. 80% of 980 errors are resolved at this stage. -
Voltage Rail Verification (Advanced):
Using a digital multimeter, check the test points on the Engine Board (often labeled +5V, +24V). If the 24V rail—which powers the engine’s communication logic—is reading below 22V, the Power Supply Unit (PSU) is failing and cannot provide enough “juice” for the boards to talk to each other. -
Component Replacement:
If cables are seated and voltages are correct, the communication ASIC on the Engine Board is likely dead. You will need to order a replacement Engine Controller Board specific to your Lexmark model.
- Technical Difficulty: Intermediate to Advanced (Requires panel removal and delicate cable handling)
- Estimated Time: 45 to 90 minutes
- Tools Needed: Phillips #2 Screwdriver, Digital Multimeter (for voltage verification), Compressed Air, ESD (Electrostatic Discharge) Wrist Strap
- Estimated Cost: $0 (if reseating cables) to $350+ (if the Engine Controller Board requires replacement)
What Triggers this Code?
The 980.xx error is rarely a random occurrence; it is typically the result of a specific failure in the printer’s internal architecture. Understanding the “why” is critical for a permanent fix.
- Inter-Board Connectivity Degradation: Over years of operation, the constant heating and cooling cycles of the printer cause microscopic expansions and contractions (thermal cycling). This can cause the ribbon cables—specifically the Low-Voltage Differential Signaling (LVDS) cables connecting the controller board to the engine board—to “creep” out of their sockets or develop oxidation on the pins.
- Firmware/Logic Handshake Failure: Sometimes the error is purely “state-based.” If the printer suffers a sudden power loss during a high-speed data transfer, the registers on the Engine Controller Board may be left in an “undefined” state. Upon reboot, the System Board fails the initial handshake protocol because the Engine Board is stuck in a logic loop.
- Voltage Instability and ASIC Damage: The Engine Board contains an Application-Specific Integrated Circuit (ASIC) that manages motor timings. If the building’s power supply experiences a “brownout” or a spike, the sensitive logic gates within this ASIC can be damaged. If the System Board cannot ping the ASIC, it throws the 980 error to prevent a mechanical “runaway” scenario.
How to Prevent Error 980.xx
To ensure this communication breakdown doesn’t return, you must address the environmental factors that stress the printer’s electronics.
- Use a Dedicated Power Line: High-voltage appliances (like space heaters or large shredders) on the same circuit as the printer can cause voltage sags. These sags interrupt the high-speed data bus between the printer’s boards. Use a high-quality surge protector with EMI/RFI filtering.
- Maintain Clean Airflow: Dust is conductive. If metallic dust from paper or environment settles on the Engine Board’s communication pins, it can cause a short. Use compressed air to clean the internal board compartments every six months.
- Keep Firmware Current: Lexmark frequently releases “PE” (Production Excellence) firmware updates that specifically improve the timing tolerances of the engine communication bus, making the printer less sensitive to minor data hiccups.
Frequently Asked Questions
Q: Can a bad fuser cause a 980.xx error?
A: Generally, no. Fuser issues typically trigger 121.xx codes. However, if the fuser has a dead short that pulls down the 24V power rail, it can indirectly cause a 980 communication error by starving the Engine Board of power. If the error persists after reseating cables, try booting the printer with the fuser disconnected to see if the error changes.
Q: Is it worth fixing a 980.xx error on an older Lexmark?
A: If the fix is simply reseating cables, absolutely. If the Engine Board requires replacement ($200-$400), you must weigh that against the page count of the machine. If the machine has exceeded 500,000 pages, the mechanical wear on other components may make a new unit more cost-effective.
Q: Why does the error only happen after the printer goes to sleep?
A: This points to a “Wake-on-LAN” or power-management failure. When the printer enters Deep Sleep, it shuts down the Engine Board to save power. If the “handshake” fails when it tries to re-energize the engine, the 980 error triggers. Disabling “Eco-Mode” or “Deep Sleep” in the settings can sometimes act as a workaround.
