If your Lexmark CX522ade is producing faded prints, streaks, smudges, or inconsistent color output, you're dealing with one of the most common issues reported by users of this multifunction color laser printer. The CX522ade, known for its reliable 45 ppm output and 1200 x 1200 dpi resolution, can experience Lexmark CX522ade poor print quality due to consumable wear, environmental factors, or incorrect settings. This guide walks you through proven printer repair and troubleshooting steps to restore crisp, professional documents.
Quick Diagnostic Checks
Before diving into detailed fix printer procedures, identify your specific symptom. Faded output typically points to toner depletion or transfer roller issues. Vertical streaks suggest a damaged drum unit. Smearing or toner rub-off indicates fuser problems. Color misregistration or banding often stems from calibration errors. Pinpointing the pattern saves time and prevents unnecessary part replacement.
Step-by-Step Troubleshooting
1
Verify Toner Cartridge Levels and Installation: Open the front cover and check the toner display on the CX522ade's 4.3-inch color touchscreen. Navigate to Status/Supplies → Toner Levels. If any color (C, M, Y, K) shows below 10%, replace with genuine Lexmark 78C1XK0, 78C1XC0, 78C1XM0, or 78C1XY0 cartridges. Remove and reinstall each cartridge, ensuring you hear the click of proper seating. Gently rock cartridges side-to-side to redistribute remaining toner if levels are low but not empty.
2
Run the Built-in Print Quality Pages: From the home screen, tap Settings → Reports → Print Quality Pages. Select all four colors and print. Examine the output for missing colors, banding, or background shading. Compare against the reference patterns shown in your CX522ade user manual. This diagnostic isolates whether the problem affects individual colors or all four, directing your printer support efforts appropriately.
3
Clean the LED Printheads and Transfer Belt: Power off and unplug the printer. Open the top cover to access the imaging kit (part number 78C0Z50). Carefully remove the kit and set it on clean, lint-free paper. Use a soft, dry microfiber cloth to gently wipe the LED printhead windows—four narrow glass strips running the width of the unit. Clean the transfer belt by rotating it manually while wiping with a dry cloth. Avoid touching the belt with bare fingers; oils cause permanent marks. Reinstall the imaging kit firmly until seated.
4
Perform Color Calibration and Registration: Return to Settings → Device → Maintenance → Calibrate Colors. Run both Auto Color Calibration and Color Registration procedures. The CX522ade will print test patterns and automatically adjust its internal color tables. This process takes approximately 5-7 minutes. For persistent color shifts, run Full Calibration from the same menu, which performs a more thorough analysis and correction cycle.
5
Adjust Paper Type and Fuser Temperature: Lexmark CX522ade poor print quality often traces to paper mismatch. In Settings → Paper, verify the loaded type matches the tray configuration. For heavy or textured stock, select Card Stock or Heavy Glossy to increase fuser temperature and pressure. For standard 20 lb bond, use Plain Paper only. Incorrect settings cause incomplete toner fusion, leading to smudging and poor adhesion. Also check that paper is stored in a low-humidity environment—damp paper causes streaking and feed issues.
6
Replace the Imaging Kit and Evaluate Fuser Life: If print quality remains degraded after cleaning and calibration, the imaging kit has likely reached its 125,000-page yield limit. Install a new 78C0Z50 imaging unit. Additionally, check fuser status in Status/Supplies → Maintenance Kit. The fuser (part 41X0247) lasts approximately 150,000 pages. Symptoms of fuser failure include toner that rubs off easily, wrinkled output, or repeating defects at 94mm intervals. Fuser replacement requires tech support or a certified technician due to high-temperature components.
⚠️ Important: Always use genuine Lexmark supplies in the CX522ade. Third-party or refilled cartridges frequently trigger Lexmark CX522ade poor print quality issues, including incorrect color density, premature drum wear, and potential warranty voidance. The printer's firmware actively monitors cartridge authentication; non-genuine supplies may perform unpredictably even if initially recognized.

Why does my Lexmark CX522ade print faded even with full toner cartridges?
Faded output with adequate toner typically indicates a failing transfer roller, worn imaging unit, or incorrect print density settings. Check that Toner Darkness in Settings → Print → Quality is set to 8-10 for normal documents. Also verify EconoMode is disabled, as this setting reduces toner coverage by up to 50% to extend cartridge life.
How often should I clean the LED printheads on my CX522ade?
For typical office environments, clean the LED printheads every 10,000 pages or when print quality degrades. High-dust settings, such as construction-adjacent offices or warehouses, may require monthly cleaning. Always power off the printer and allow components to cool before cleaning to prevent damage to sensitive optical surfaces.
What causes horizontal lines across all colors on CX522ade prints?
Horizontal lines spanning multiple colors usually indicate contamination on the transfer belt or damage to the belt's coating. Inspect the belt for scratches, toner buildup, or foreign objects. If cleaning doesn't resolve the issue, replace the imaging kit. Single-color horizontal lines typically point to a defective drum within that color's developer unit.
