The Lexmark Error 900.xx (often appearing as 900.00, 900.19, or 900.80) is a generic “Software Error” or “RIP (Raster Image Processor) Software Error.” Essentially, it means your printer’s internal brain has encountered a command or a piece of data that it doesn’t know how to process, leading to a system crash.
đź“– Important: Official Documentation
Incorrect repairs can cause fire or injury. Always verify with the manufacturer’s manual.
You might notice your printer suddenly freezing mid-job, making strange rhythmic clicking noises as it tries to process data, or simply displaying a bright blue or white screen with this daunting code. It can feel like your printer has completely given up the ghost, but don’t worry! Most of the time, this is a communication hiccup rather than a mechanical failure, and we can get you back to printing with a little bit of patience and some simple “brain surgery” for your machine.
Symptoms of Error 900.xx
Identifying the onset of a 900.xx error is usually quite startling. You might see the display screen flash intermittently before settling on a static error message. Frequently, the printer will stop in the middle of a page, leaving a half-printed sheet stuck in the rollers, while the status light blinks a frantic amber or red.
Other physical signs include a completely unresponsive control panel where no amount of button-mashing produces a beep or a change in the menu. In some cases, the printer may enter a “reboot loop,” where it tries to start up, displays the Lexmark logo, and then immediately crashes back to the error screen. If you are printing via a network, your computer might report that the printer is “Offline” or “Busy” indefinitely, even though the machine is powered on.
Troubleshooting & Replacement Instructions
Don’t be intimidated! We are going to walk through this step-by-step. Follow these instructions in order, as we’ll start with the easiest fixes first.
- The “Power Cycle” and Buffer Clear:
First, turn off the printer using the power switch on the side or back. Now, and this is important, unplug the power cord from the wall outlet. While it’s unplugged, disconnect the USB or Ethernet cable. Press and hold the printer’s “Power” button for 15 seconds to drain any residual electricity from the capacitors. Wait a full 5 minutes. This clears the printer’s temporary memory (RAM) which might be holding the “bad” data. - Clear the Computer Print Queue:
Before plugging the printer back in, go to your computer. In Windows, search for “Services,” find “Print Spooler,” right-click it, and hit “Stop.” Then navigate toC:\Windows\System32\spool\PRINTERSand delete every file in that folder. Go back to Services and “Start” the Spooler. This ensures that when the printer wakes up, your computer doesn’t immediately send it the same “poison” print job that caused the crash. - The Bare-Bones Boot:
Plug the power cord directly into a wall outlet (avoid power strips for this test). Turn the printer on without the network or USB cables attached. If the printer reaches the “Ready” state, the issue was definitely a bad print job or a network conflict. If it still shows Error 900.xx, we need to look at the firmware. - Updating the Firmware (The Digital Fix):
If you can access the printer’s menus, print a “Network Setup Page” to find its IP address. Type that IP into a web browser on your computer to open the Lexmark Embedded Web Server. Download the latest firmware from Lexmark’s support site (it usually ends in .fls). Upload this file through the “Update Firmware” section of the web menu. Warning: Never turn off the printer during a firmware update, or you could permanently “brick” the machine. - Inspecting the Controller Board (The Physical Fix):
If software fixes fail, we need to check the hardware. Safety Warning: Ensure the printer is unplugged! Use your Phillips head screwdriver to remove the side panel (usually the right side when facing the printer). Locate the large green circuit board. Gently press down on any visible memory chips or ribbon cables to ensure they haven’t vibrated loose. If you see bulging capacitors (they look like tiny cans that are swollen on top), the board may need replacement.

Technical Explanation of the Fault
To fix the problem, we first need to understand why your Lexmark is acting out. Here are the primary culprits behind the 900.xx software crash:
- Corrupt Print Job Data: This is the most common cause. If you try to print a complex PDF or a document with unusual fonts, the data stream can become “malformed.” When the printer’s controller board receives this “gibberish,” it doesn’t know how to translate it into ink on paper, so it triggers a protective shut-down (the 900.xx error) to prevent hardware damage.
- Firmware Incompatibility: Think of firmware as the printer’s operating system. As Windows or macOS updates, they change how they talk to hardware. If your printer’s firmware is several years old, it might literally stop understanding the language your computer is speaking, leading to a fatal software conflict.
- Voltage Fluctuations and Spikes: Printers are sensitive electronic devices. A minor power surge or “dirty power” from a shared wall outlet can cause the volatile memory (RAM) on the controller board to flip a bit. This leads to internal data corruption that the printer interprets as a software failure.
- Hardware Component Failure: While less common, the 900.xx can indicate that the physical Controller Board or the internal Hard Drive (on higher-end models) has developed a bad sector or a failing capacitor. This is essentially “dementia” for the printer, where it can no longer access its own instructions.
How to Prevent Error 900.xx
Once you’ve cleared that error, you definitely don’t want to see it again! Here is how you can keep your Lexmark running smoothly:
- Invest in a High-Quality Surge Protector: Since voltage spikes are a major cause of software logic errors, plugging your printer into a dedicated surge protector (or better yet, a small UPS) ensures the “brain” gets a steady, clean flow of electricity.
- Stay Current with Firmware: Make it a habit to check the Lexmark website every six months for firmware updates. These updates often contain “patches” for newly discovered software bugs that cause the 900.xx error code.
- Use Standard Print Drivers: Whenever possible, use the “Universal Print Driver” provided by Lexmark rather than the generic drivers provided by Windows or Apple. The official drivers are optimized to package data in a way the printer understands perfectly.
Frequently Asked Questions
Q: Does a 900.xx error mean my printer is permanently broken?
A: Not at all! In over 80% of cases, this error is caused by a “confused” controller board rather than a “broken” one. Following the power cycle and print queue clearing steps usually resolves the issue without costing a dime.
Q: What is the difference between Error 900.00 and 900.80?
A: While both are software errors, 900.00 is a generic kernel crash, whereas 900.80 specifically points to an error in the “font” or “image” rendering engine. The 900.80 version almost always means a specific file you are trying to print is the culprit.
Q: Can a low-quality USB cable cause this software error?
A: Surprisingly, yes. If a USB cable is poorly shielded or too long (over 10 feet), data packets can be lost or corrupted during transmission. When the printer receives these fragmented packets, it can trigger a 900.xx RIP error because it can’t make sense of the incoming data.
