When your Canon PIXMA TS5020 starts producing double prints—where text and images appear duplicated with a slight offset or shadow effect—it wastes ink and produces unprofessional results. This common printing problem typically stems from misaligned print heads, incorrect driver settings, or mechanical issues with the encoder strip. As a 5-color individual ink system printer with a maximum 4800 x 1200 dpi resolution, the TS5020 relies on precise head positioning; even minor calibration errors can cause noticeable ghosting or double image output. The good news is that most double printing issues on this all-in-one inkjet can be resolved through systematic troubleshooting without needing immediate printer repair.
Common Causes of Double Printing on the TS5020
Canon PIXMA TS5020 double printing usually occurs due to three primary factors: print head misalignment after cartridge replacement or paper jams, outdated or corrupted printer drivers sending erroneous positioning data, or a dirty encoder strip that guides the carriage assembly. Environmental factors like temperature fluctuations and low-quality paper can exacerbate these issues. Understanding the root cause helps you apply the right fix rather than wasting time on ineffective solutions.
Step-by-Step Troubleshooting Guide
1
Run Automatic Print Head Alignment: On the TS5020's 3.0" LCD touchscreen, navigate to Setup (gear icon) > Maintenance > Auto Print Head Alignment. Select "Yes" when prompted, then load plain A4 or Letter-sized paper in the rear tray. The printer will print a test pattern and automatically adjust head positions. This process takes approximately 6-8 minutes. Run this twice if ghosting persists, as the second pass often fine-tunes corrections from the first attempt.
2
Perform Manual Print Head Alignment: If automatic alignment fails to fix the double printing, access Setup > Maintenance > Manual Print Head Alignment. The TS5020 will print a pattern with multiple alignment rows. Examine the printed output carefully and select the pattern number with the least visible overlap or separation for each row on the touchscreen. This granular control often resolves stubborn misalignment that automatic processes miss, particularly after installing new CLI-271/PGI-270 ink cartridges.
3
Clean the Encoder Strip: Power off and unplug the TS5020. Open the scanning unit (cover) to access the interior. Locate the clear plastic encoder strip—a thin film strip running horizontally behind the print head carriage. Dampen a lint-free cloth with distilled water or isopropyl alcohol (70% or higher) and gently wipe both sides of the strip from left to right. Avoid stretching or dislodging the strip, as damage requires professional printer repair. Allow 10 minutes to dry completely before powering on.
4
Update or Reinstall Printer Drivers: Outdated drivers frequently cause Canon PIXMA TS5020 double printing by sending incorrect positioning commands. Visit Canon's official support site and download the latest TS5020 Full Driver & Software Package for your operating system (Windows 11/10 or macOS 13+). Uninstall the existing driver through Control Panel (Windows) or System Preferences > Printers & Scanners (Mac), restart your computer, then install the fresh download. Ensure you select "Standard" print mode during setup rather than "Fast" or "Draft," which can reduce positioning accuracy.
5
Check Paper Settings and Loading: Verify that the rear tray paper guides are snug against your media edges without bending the paper. In the print dialog, confirm the paper type matches your loaded stock—mismatched settings cause the TS5020 to apply incorrect ink amounts and head passes, creating double image artifacts. For plain paper, select "Plain Paper" and "Standard" print quality. Avoid overloading the 100-sheet rear tray, and fan paper before loading to prevent multiple sheets feeding simultaneously, which can trigger ghosting.
6
Perform Deep Print Head Cleaning: If double printing continues after alignment attempts, dried or clogged nozzles may be forcing compensation that creates ghost images. Access Setup > Maintenance > Deep Cleaning on the touchscreen. This consumes more ink than standard cleaning but thoroughly clears blocked CLI-271 nozzles. After completion, print a nozzle check pattern (Setup > Maintenance > Print Nozzle Check Pattern) to verify all 5,632 nozzles fire correctly. Run deep cleaning twice maximum; further attempts without improvement suggest hardware issues requiring printer support.
⚠️ Important: Never touch the encoder strip with bare fingers—skin oils create permanent marks that worsen positioning errors. Avoid using tap water or abrasive materials for cleaning, as mineral deposits and scratches can permanently damage this precision component. If the carriage makes unusual grinding noises during alignment attempts, power off immediately and contact certified tech support, as continued operation may damage the timing belt or carriage motor.
Preventing Future Double Printing Issues
Regular maintenance keeps your Canon PIXMA TS5020 operating accurately. Print at least once weekly to prevent nozzle drying that leads to compensation-based ghosting. Keep firmware updated through Canon's IJ Printer Assistant Tool or the printer's network update function. Store replacement CLI-271 and PGI-270 cartridges sealed in their original packaging until installation, and always allow the printer to complete its automatic alignment routine after cartridge changes rather than canceling mid-process.
Frequently Asked Questions
Why does my Canon PIXMA TS5020 double print only in color but not black?
This indicates misalignment specifically in the color print head (dedicated to CLI-271C, M, and Y cartridges) rather than the black PGI-270BK head. Run manual alignment and focus on evaluating the color pattern rows most carefully. Replace color cartridges if they're near empty, as low ink pressure can cause inconsistent droplet placement that mimics double printing.
Can using third-party ink cause Canon PIXMA TS5020 double printing?
Yes, non-Canon ink formulations can alter viscosity and drying time, affecting how droplets land on paper and interact with subsequent passes. While many third-party cartridges work acceptably, inconsistent quality control means some batches cause flow irregularities. If double printing began after switching to compatible cartridges, reinstall genuine Canon ink and run two deep cleaning cycles before retesting.
How do I know if my TS5020 needs professional repair instead of home troubleshooting?
Seek professional printer repair if: double printing persists after completing all six steps above, the carriage assembly makes clicking or grinding sounds, the encoder strip appears damaged or detached, or ink leaks visibly from the print head area. Physical damage to the timing belt or carriage rails requires specialized tools and parts replacement that exceed home troubleshooting scope.
