If your Canon imageCLASS MF113w is producing prints with inaccurate colors, faded output, or noticeable shifts from what appears on your screen, you're dealing with a color mismatch problem. This compact monochrome laser all-in-one printer is designed primarily for black-and-white document printing, but when using grayscale or halftone modes, color accuracy still matters for professional results. This guide walks you through proven troubleshooting steps to diagnose and fix Canon imageCLASS MF113w color mismatch issues, restore print quality, and determine when professional printer repair may be needed.
Understanding Color Mismatch on the MF113w
The Canon imageCLASS MF113w uses a single-cartridge system with Canon 047 black toner. While not a color printer, "color mismatch" in this context typically refers to grayscale tonal inaccuracy, contrast problems, background shading, or streaking that mimics color distortion. These issues often stem from toner degradation, incorrect driver settings, or hardware calibration problems that require targeted troubleshooting to resolve.
Troubleshooting Steps to Fix Printer Color Problems
1
Check and Replace the Canon 047 Toner Cartridge: Remove the toner cartridge by opening the front panel and pulling it straight out. Gently rock the cartridge side-to-side five times to redistribute remaining toner. Inspect the drum surface for scratches, scoring, or discoloration. If the toner level is below 20% or the cartridge has exceeded 1,600 pages, install a genuine Canon 047 replacement. Third-party cartridges frequently cause Canon imageCLASS MF113w color mismatch issues due to incompatible toner formulations.
2
Calibrate Print Density Through the Control Panel: Press the Menu button, navigate to Adjustment Settings > Density, and select Auto Adjust. The printer will output a calibration page—place this face-down on the scanner glass and press Start to complete the process. For manual fine-tuning, adjust the density slider between -3 and +3 based on whether prints appear too light or too dark. Run a test print after each adjustment to verify improvement.
3
Update or Reinstall the Printer Driver: Outdated drivers commonly cause color rendering errors. Visit Canon's support site and download the latest UFR II LT driver for your operating system (Windows 11/10 or macOS 13+). Uninstall the existing driver from Control Panel > Programs > Canon MF113w, restart your computer, then install the new driver. During setup, select Grayscale or Black and White as the default color mode to prevent software-based color conversion errors that trigger perceived Canon imageCLASS MF113w color mismatch.
4
Clean the Corona Wire and Drum Unit: Open the front cover and remove the toner cartridge. Locate the blue cleaning tab on the left side of the drum unit—slide it back and forth three times, then return it to its original position. Use a lint-free cloth lightly moistened with isopropyl alcohol to wipe the scanner glass and the thin white strip (CIS sensor calibration strip) beneath the document feeder. Dust accumulation on these components directly affects tonal accuracy and can create banding that resembles color distortion.
5
Verify Application and Document Color Settings: In your printing application (Adobe Acrobat, Microsoft Word, etc.), access File > Print > Printer Properties. Ensure Grayscale is selected rather than RGB Color or CMYK Color, which forces the MF113w to interpret color data it cannot properly render. Under the Quality tab, set Print Quality to 600 x 600 dpi and disable Toner Save Mode, which reduces ink density and creates washed-out prints that users often mistake for color mismatch.
6
Perform a Full Printer Reset and Firmware Check: With the printer powered on, press and hold the Stop button until the alarm lamp flashes 17 times, then release to restore factory defaults. Reconfigure your wireless or USB connection. Check the current firmware version through Menu > Device Settings > Firmware Version and compare against Canon's latest release. Firmware updates for the MF113w series have addressed halftone rendering bugs—install updates via USB connection for stability. Persistent Canon imageCLASS MF113w color mismatch after these steps indicates potential laser scanner unit or main controller board failure requiring professional printer repair.
⚠️ Important: Never use compressed air to clean inside the MF113w. The high-pressure spray can drive toner particles into the laser scanner assembly or electrical contacts, causing permanent damage and voiding your warranty. Always use the built-in cleaning functions or gently wipe with appropriate materials.

If these troubleshooting steps didn't resolve the issue, our certified Canon printer technicians are standing by. Get expert support in minutes.
If you've completed all six troubleshooting steps and continue experiencing Canon imageCLASS MF113w color mismatch, the issue likely involves internal hardware. The laser scanner unit (LSU), which writes the electrostatic image to the drum, can develop alignment problems. The DC controller PCB may fail to properly modulate laser intensity, or the drum unit itself may have reached end-of-life with subtle damage invisible to casual inspection. At this stage, DIY fixes risk further damage—contact qualified tech support for diagnostic service and component-level printer repair.
Frequently Asked Questions
Why does my Canon imageCLASS MF113w print gray backgrounds on white documents?
Gray background shading typically indicates a dirty corona wire, worn drum unit, or incorrect density setting. Clean the corona wire using the blue tab, perform the auto density calibration, and replace the drum if it has exceeded 12,000 pages. If the problem persists, the high-voltage power supply may be failing and requires professional printer support.
Can using non-Canon toner cause color mismatch problems?
Yes, third-party toner cartridges are a leading cause of print quality issues with the MF113w. Incompatible toner particle sizes and charge characteristics prevent proper development on the drum, resulting in inconsistent density, streaking, and tonal inaccuracy. Canon's 047 genuine cartridges are specifically formulated for the 23-page-per-minute engine in this model. For reliable output and to avoid printer repair costs, use OEM supplies.
How often should I calibrate my MF113w to prevent color problems?
Run the auto density calibration after every toner cartridge replacement and monthly during heavy use periods. Environmental changes—particularly humidity shifts above 60% or below 30%—also affect toner behavior and may necessitate more frequent calibration. Enable Auto Calibration in the device settings menu if available with your firmware version for maintenance-free optimization.
