If your Canon PIXMA MG5220 printing lines are ruining documents and photos, you're dealing with one of the most common inkjet printer problems. This all-in-one printer uses a 5-color individual ink system (CLI-226/PGI-225 cartridges) that can develop streaks, banding, or horizontal lines when printhead nozzles clog, ink dries out, or alignment drifts. Whether you're seeing thin white gaps, dark streaks, or repeating patterns across the page, this troubleshooting guide will walk you through proven fixes that restore clean output without unnecessary printer repair costs.
Quick Diagnosis: What Type of Lines Are You Seeing?
Before jumping into fixes, identify your symptom. Horizontal white lines typically indicate clogged nozzles. Vertical streaks or smearing suggest dirty encoder strips or misaligned cartridges. Repeating dark bands every 1-2 inches often point to a failing printhead or contaminated rollers. The Canon PIXMA MG5220's ChromaLife 100+ system is excellent when maintained, but pigment-based black ink and dye-based color inks have different clogging tendencies. Run a nozzle check first: press Setup > Maintenance > Print nozzle check pattern to see exactly which color channels are affected.
Step-by-Step Troubleshooting to Fix Printer Line Issues
1
Run the Built-in Printhead Cleaning Cycle: On the MG5220's control panel, navigate to Setup > Maintenance > Cleaning. Select "Yes" to start the automated cleaning cycle, which forces fresh ink through the nozzles to dissolve dried ink deposits. Run this up to two times if lines persist, but wait 30 minutes between cycles to prevent overheating the printhead. After cleaning, print another nozzle check to verify improvement. This basic printer support step resolves roughly 60% of line-related issues.
2
Perform Deep Cleaning for Stubborn Clogs: If standard cleaning fails, access Setup > Maintenance > Deep Cleaning. This intensive cycle uses significantly more ink but targets hardened blockages in the PIXMA MG5220's thermal inkjet nozzles. Note that deep cleaning consumes approximately 2-3% of each cartridge's capacity, so ensure your CLI-226 and PGI-225 tanks are at least 30% full before starting. Follow immediately with a nozzle check—if gaps remain in the same positions, the clog may be too severe for software methods alone.
3
Manually Clean the Printhead with Distilled Water: For persistent Canon PIXMA MG5220 printing lines, remove the printhead assembly: power off, open the cover, lift the gray locking lever, and gently extract the printhead (it contains all five ink chambers). Place it on a paper towel dampened with distilled water—never tap water, as minerals cause damage. Let it sit for 10 minutes, then gently blot the nozzle plate. Reinstall and run one standard cleaning cycle. This hands-on fix printer approach often succeeds when automated cycles fail.
4
Clean the Encoder Strip and Paper Feed Rollers: Vertical lines or intermittent streaking often stem from a dirty encoder strip—that thin, semi-transparent plastic strip running horizontally behind the printhead carriage. Power off, then wipe it gently with a lint-free cloth slightly moistened with water. Also clean the paper feed rollers (accessible from the rear tray area) with a damp cloth to remove paper dust and ink residue that transfers during feeding. This maintenance step prevents recurring troubleshooting cycles for the same symptom.
5
Align the Printhead and Check Cartridge Seating: Navigate to Setup > Maintenance > Auto head alignment. The MG5220 prints a test pattern and uses its optical sensor to calibrate nozzle firing timing. Misalignment causes visible banding in graphics and photos. While the cover is open, verify each CLI-226 color cartridge and PGI-225 black tank clicks firmly into place—loose cartridges create uneven pressure and irregular ink flow. Replace any cartridge showing low ink warnings, as near-empty tanks introduce air bubbles that cause lines.
6
Update Firmware and Printer Drivers: Outdated software can mismanage ink firing sequences. Visit Canon's support site and download the latest MG5220 firmware and driver package (currently version 1.05 or later). During installation, select the option to remove existing drivers completely. After updating, verify your print settings: in Windows, check Control Panel > Devices and Printers > Printing Preferences > Maintenance tab; on Mac, use System Preferences > Printers & Scanners > Options & Supplies. Proper tech support foundation prevents software-induced print quality degradation.
⚠️ Important: Never use compressed air, alcohol-based cleaners, or sharp objects on the printhead nozzles. These can permanently damage the thermal resistors or scratch the precision nozzle plate. If you've completed all steps above and Canon PIXMA MG5220 printing lines persist across multiple ink cartridge sets, the printhead itself may have reached end-of-life (typically 3-5 years with regular use). Replacement part QY6-0073 is available through Canon parts distributors, though professional diagnosis is recommended before this investment.
Preventing Future Line Problems
Regular use is the best prevention for the PIXMA MG5220. Print at least one color page weekly to keep ink flowing through all channels. Use genuine Canon CLI-226/PGI-225 cartridges—third-party inks have inconsistent viscosity that accelerates clogging. Enable "Keep print quality" in the maintenance menu, which automatically performs micro-cleaning cycles during startup. Store the printer in a climate-controlled environment; temperatures below 50°F or above 90°F affect ink chemistry and increase drying rates. For photo printing, always select the correct media type in print settings to optimize droplet formation.

Why does my Canon PIXMA MG5220 print lines only in color but not black?
This indicates clogged nozzles specifically in the dye-based color cartridges (CLI-226C, M, Y). The pigment-based PGI-225 black uses a separate ink channel with different drying properties. Run targeted cleaning cycles and consider replacing the affected color cartridges if they're older than six months, as dye inks crystallize faster than pigments.
Can I fix printer line issues without buying new ink cartridges?
Yes, if your cartridges have sufficient ink. Manual printhead cleaning with distilled water and thorough encoder strip cleaning often resolve lines without cartridge replacement. However, cartridges below 20% capacity may introduce air that perpetuates the problem. For printer repair avoidance, maintain at least 30% ink levels during intensive cleaning procedures.
How do I know if my MG5220 printhead needs replacement?
If lines appear in identical positions after new genuine cartridges, multiple deep cleanings, and manual soaking, the thermal printhead likely has permanent nozzle damage. The QY6-0073 printhead averages $80-120; compare this to replacement printer costs. Our tech support team can help evaluate whether repair or replacement makes economic sense for your usage volume.
