When your Xerox VersaLink B400 won't print, it disrupts your entire workflow. This monochrome laser printer is built for high-volume office environments, but like any complex device, it can experience communication failures, driver conflicts, or hardware issues that prevent output. This troubleshooting guide walks you through proven steps our printer repair technicians use to diagnose and fix VersaLink B400 printing problems—getting you back to productive printing quickly without unnecessary service calls.
Initial Diagnostics: Check the Basics First
Before diving into advanced troubleshooting, verify these common causes. Nearly 40% of "won't print" cases resolve with simple checks that take under two minutes.
1
Verify Power and Display Status: Check that your VersaLink B400 shows "Ready" on the 5-inch color touchscreen. If the display is dark, press the power button firmly for 3 seconds. A blinking green LED indicates the printer is waking from sleep mode—wait 30 seconds. If the screen shows any error code (such as 016-XXX or 039-XXX series), note it down before proceeding with any fix printer steps.
2
Check Physical Connections: For USB-connected setups, ensure the cable is securely seated in the rear USB 3.0 port (not the front walk-up port). For network connections, verify the Ethernet cable clicks firmly into the Gigabit Ethernet port and the link LED glows steady green. Try a different cable if you suspect damage—USB cable failures cause more printer support calls than most users expect.
3
Inspect the Toner Cartridge: Open the front cover and remove the black toner cartridge (part number 106R03584 standard yield or 106R03585 high yield). Shake it gently side-to-side to redistribute toner, then reinstall until it clicks. The VersaLink B400 will not print if it detects an incompatible or exhausted cartridge. Check the touchscreen for "Replace Toner" messages that might not trigger the usual status LED.
Advanced Troubleshooting Steps
If basic checks don't resolve why your Xerox VersaLink B400 won't print, proceed with these deeper diagnostics targeting software, network, and print path issues.

Clear the Print Queue and Restart Spooler: On Windows, open Services.msc, locate "Print Spooler," right-click and select Restart. Then navigate to C:\Windows\System32\spool\PRINTERS and delete all files (administrator rights required). On Mac, open Terminal and run cancel -a followed by sudo cupsenable B400. Corrupted jobs frequently block all subsequent output without showing obvious errors.
5
Update or Reinstall the Print Driver: Download the latest VersaLink B400 V4 Print Driver from Xerox's official support site. Uninstall the existing driver through Windows "Apps & Features" or Mac "Printers & Scanners," then install fresh. For optimal troubleshooting results, select the specific B400 model during installation rather than using a universal PCL6 driver. Enable bidirectional communication when prompted—this allows automatic supply status reporting.
6
Test with a Configuration Page: On the touchscreen, navigate to Device > About > Information Pages > Configuration Page and tap Print. If this page outputs successfully, the print engine and paper path are functional—the issue lies upstream in network, driver, or application settings. If even the configuration page fails, you likely have a hardware problem requiring professional printer repair intervention.
⚠️ Important: Never force open toner doors or paper trays while the VersaLink B400 displays "Processing" or during warm-up. The fuser operates at approximately 180°C (356°F) and internal components move at high speed. Forcing mechanisms can damage gears, void your service agreement, and cause serious burns. Always wait for "Ready" status before performing any physical intervention.

Why does my VersaLink B400 show "Ready" but still won't print?
This typically indicates a communication breakdown between your computer and printer. Check that the IP address hasn't changed if using DHCP—set a static IP or reservation to prevent this. Also verify Windows Firewall or third-party antivirus isn't blocking port 9100 (raw) or port 515 (LPR). Printing a configuration page confirms the engine works; the problem is almost always network or driver-related.
Can a firmware update fix my B400 printing problems?
Yes, firmware updates often resolve specific "won't print" bugs. Xerox has released patches addressing USB detection failures, certain PDF rendering stalls, and Wi-Fi Direct connectivity issues. Check your current firmware version via Device > About > Version and compare against the latest release on Xerox's support portal. Apply updates during low-usage periods as the printer will be unavailable for 10-15 minutes.
What does error code 016-749 mean on the VersaLink B400?
Error 016-749 indicates a "Job Format Error"—the printer received data it cannot process. This often occurs with corrupted PDFs, incompatible font embedding, or driver mismatches. Try printing from a different application, simplify the document (reduce graphics, use standard fonts), or switch from PCL6 to PostScript driver if available. Persistent 016-series errors may require tech support to analyze detailed job logs.
