When your HP LaserJet Enterprise M507 stops producing color output, it can disrupt critical business workflows. This monochrome-capable laser printer with optional color accessories may experience color printing failures due to toner cartridge issues, imaging drum problems, driver misconfigurations, or internal hardware faults. This guide provides step-by-step printer repair instructions to help you fix printer color output problems and restore full functionality to your office equipment.
Initial Diagnosis for Color Printing Failures
Before attempting any troubleshooting, verify whether your M507 model actually supports color printing. The base HP LaserJet Enterprise M507 is a monochrome printer; color capability requires the optional HP Color LaserJet Enterprise M507x configuration or connected color accessories. If color was previously working, document when the HP LaserJet Enterprise M507 color not printing issue began and whether any recent changes were made to the printer or network.
Step-by-Step Troubleshooting Guide
1
Verify Color Configuration and Printer Model: Check your exact model number on the printer label. The M507dn and M507n are monochrome-only. Color printing requires the M507x model or a color-capable configuration. Navigate to the printer's control panel, press the Settings icon, select System Setup > Product Information, and confirm "Color Capability" shows "Enabled." If color is disabled, you may need a firmware update or hardware upgrade through HP printer support.
2
Inspect and Replace Color Toner Cartridges: Open the front door and remove each toner cartridge (CF460X black, CF461X cyan, CF462X yellow, CF463X magenta for color models). Shake each cartridge gently side-to-side to redistribute toner. Check the chip contacts for debris and clean with a lint-free cloth. If any cartridge shows below 10% capacity or has been installed for over 24 months, replace it with genuine HP 655A or 656X toner. Third-party cartridges often cause HP LaserJet Enterprise M507 color not printing problems.
3
Clean or Replace the Imaging Drum: The imaging drum (CF440X series for color models) transfers toner to paper. Remove the drum unit and examine for scratches, wear lines, or toner buildup. Gently wipe the drum surface with a dry, lint-free cloth—never use liquids. Rotate the drum by hand to check for flat spots or damage. If the drum has exceeded its 50,000-page rated life or shows visible defects, install a replacement drum. Improper drum installation is a frequent cause of color output failure requiring printer repair.
4
Update or Reinstall Printer Drivers: Outdated drivers frequently cause color printing issues. On Windows, go to Settings > Printers & Scanners, remove the M507, then download the latest Universal Print Driver (UPD) or specific PCL6 driver from HP's support site. For Mac, remove the printer in System Preferences, then add it using the latest AirPrint or HP driver. During installation, select "Color" as the default mode in printing preferences. Corrupted driver profiles are a common tech support finding for the HP LaserJet Enterprise M507 color not printing issue.
5
Check Color Settings in Application and Printer: Open any document, select Print, then click Properties or Preferences. Navigate to the Color tab and ensure "Print in Grayscale" is NOT selected. On the printer's embedded web server (EWS), type the printer's IP address into a browser, log in as administrator, go to the Color tab, and verify "Color Mode" is set to "Automatic" or "Color." Some enterprise policies disable color to reduce costs—contact your IT department if settings appear locked.
6
Perform a Hard Reset and Firmware Update: With the printer powered on, disconnect the power cord and Ethernet/USB cables. Wait 60 seconds, then reconnect power only. Once fully booted, check for firmware updates via the control panel: Settings > Service > LaserJet Update > Check for Updates. Alternatively, download the latest firmware from HP's website and install via USB. Firmware version 2407087_000240 or later resolves known color processing bugs. If color still fails after all troubleshooting, the DC controller or color detection sensor may need professional printer repair.
⚠️ Important: Never force toner cartridges or imaging drums into position—damage to the transfer roller or fuser can result in costly repairs exceeding $400. If you notice burning smells, unusual noises, or error codes 59.F0 (developer motor failure) or 10.23.70 (color plane registration error), stop troubleshooting immediately and contact certified printer support. Attempting to disassemble the laser scanner assembly voids warranty coverage and poses eye safety risks from Class 3B laser radiation.
Frequently Asked Questions
Why is my HP LaserJet Enterprise M507 only printing black and white?
The base M507 models are monochrome-only. Color printing requires the M507x variant or specific color hardware upgrades. Check your model suffix—"dn" and "n" indicate monochrome; "x" indicates color capability. If you have a color-capable model, verify that color mode is enabled in both the driver and printer EWS settings, and that all color toner cartridges are genuine HP products with adequate remaining life.
Can I use third-party toner to fix printer color issues on the M507?
HP strongly recommends against third-party toner for the LaserJet Enterprise M507. Non-HP cartridges often lack proper chip authentication, causing the printer to reject color cartridges entirely or produce faded, inaccurate colors. Genuine HP 655A/656X toners include proprietary toner formulations and chips that communicate remaining life and authenticity to the printer. Using third-party supplies may also void your HP warranty for related failures.
How do I know if my M507 needs professional tech support versus DIY troubleshooting?
Attempt the steps in this guide first—they resolve approximately 75% of HP LaserJet Enterprise M507 color not printing cases. However, if you encounter persistent error codes (especially 59.x, 50.x, or 10.x series), physical damage to internal components, or color failure after replacing all consumables and updating firmware, the issue likely involves the DC controller, laser scanner, or color registration sensors. These require specialized diagnostic tools and should be handled by authorized HP printer repair technicians.
