HP Color LaserJet Pro M255dw Missing Colors

If your HP Color LaserJet Pro M255dw missing colors is producing documents with faded hues, completely absent color channels, or prints that look washed out, you're dealing with one of the most common laser printer problems. This issue typically stems from toner cartridge problems, imaging drum faults, or internal calibration errors. The M255dw uses four separate toner cartridges (CF210X Black, CF211A Cyan, CF212A Yellow, CF213A Magenta) and a single imaging drum unit, which means any failure in one component can cause specific colors to drop out entirely. This guide provides concrete printer repair steps you can perform yourself before contacting professional printer support.

Identifying Which Color Is Missing

Before you attempt to fix printer problems on your M255dw, you need to determine exactly which color channel has failed. Print a Supplies Status Page by pressing the Information button (i) on the control panel, then selecting Reports > Supplies Status. Next, print a Configuration Page from Reports > Configuration/Status Pages. Compare the color bars on these reports—if one color bar is blank or severely streaked, you've isolated the problem to that specific toner or the imaging drum.

Step-by-Step Troubleshooting for HP Color LaserJet Pro M255dw Missing Colors

Check Toner Levels and Replace Low Cartridges: Open the front door and inspect each toner cartridge's remaining life through the control panel. Navigate to Setup > System Setup > Supply Levels. If any color shows below 10%, replace that cartridge immediately. For HP Color LaserJet Pro M255dw missing colors issues, even cartridges reading 15-20% can fail to deposit sufficient toner due to developer unit saturation. Use genuine HP 206A or 206X cartridges—third-party toners often cause color dropout in this model.

Redistribute Toner by Rocking Cartridges: Remove each toner cartridge by grasping the handle and pulling straight out. Gently rock the cartridge side-to-side and front-to-back 10-12 times to redistribute settled toner powder. This troubleshooting step is especially effective if your printer sat unused for weeks. Reinsert cartridges firmly until they click into place. Print a demo page to verify color restoration.

Clean the Imaging Drum and ITB Unit: The M255dw uses a transfer belt (ITB) behind the toner cartridges. Remove all four toner cartridges, then carefully remove the imaging drum unit by pressing the blue release tab. Use a lint-free microfiber cloth to gently wipe the drum surface—never touch it with bare fingers. Inspect the ITB for toner buildup or scratches. Clean the ITB using HP's built-in cleaning function: Setup > Service > Cleaning Page. Run this cycle twice if colors remain missing.

Perform a Full Color Calibration: Color misregistration can make colors appear missing when they're actually shifted. Access Setup > System Setup > Print Quality > Color Calibration > Calibrate Now. The M255dw will print multiple alignment pages and automatically adjust its internal color tables. This process takes 4-6 minutes. For persistent HP Color LaserJet Pro M255dw missing colors problems, perform calibration three consecutive times with the printer powered on continuously.

Reset the Printer to Factory Defaults: Firmware glitches can cause color channel failures. From the control panel, navigate to Setup > Service > Restore Defaults. Select Restore Factory Defaults and confirm. This resets all settings including network configuration, so document your IP settings first. After reset, reconfigure Wi-Fi and print a test page. This tech support step resolves approximately 15% of color dropout cases caused by corrupted color lookup tables.

Inspect and Replace the Imaging Drum: If specific colors remain missing after cartridge replacement, the imaging drum (HP 659A, W2010A) has likely failed. The drum has a rated life of 24,000 pages but degrades faster in high-humidity environments. Remove the drum and examine it under bright light for scratches, scoring, or discoloration on the colored roller surfaces. A damaged drum cannot be repaired—replacement is the only fix printer option. Install a new imaging drum and run the supplied calibration routine.

⚠️ Important: Never expose toner cartridges or the imaging drum to direct sunlight for more than a few minutes—UV light permanently damages the photosensitive drum surface. Always store replacement supplies in their original packaging until installation. Attempting to manually clean the drum with solvents, alcohol, or water will destroy it immediately and void your remaining warranty coverage.

Preventing Future Color Loss on Your M255dw

Regular printer maintenance prevents most HP Color LaserJet Pro M255dw missing colors recurrences. Print at least one color page weekly to keep toner flowing freely. Keep the printer in an environment between 50-80°F with 30-70% relative humidity. Enable Automatic Calibration in the Embedded Web Server (EWS) so the printer self-adjusts after every 50 pages. When replacing toners, always replace the imaging drum if you've exceeded 20,000 pages—even if the drum hasn't reported end-of-life yet.

Frequently Asked Questions

Why is my HP Color LaserJet Pro M255dw printing only yellow and black?

This indicates simultaneous cyan and magenta toner failure, or more commonly, a damaged imaging drum where those two color stations have failed. First replace both the cyan (CF211A) and magenta (CF213A) cartridges. If the problem persists, replace the imaging drum unit (W2010A) as the drum's individual color stations can fail independently even when others work normally.

Can I use remanufactured toner cartridges without getting missing colors?

While remanufactured cartridges may work initially, the HP Color LaserJet Pro M255dw has strict toner density sensors that often reject non-HP formulations after 500-1,000 pages. For reliable color output, HP recommends genuine 206A/206X cartridges. If you must use third-party options, select those specifically rated for the M255dw with updated chips that match HP's latest firmware requirements.

How do I know if the problem is the toner or the imaging drum?

Perform this diagnostic: Print a Configuration Page. If one color is completely absent while others look normal, replace that toner first. If multiple colors are faded or streaked equally, or if colors return briefly after cartridge shaking then fail again within 50 pages, the imaging drum is failing. The drum distributes toner evenly—when it degrades, all colors suffer, though often one shows symptoms first.
