Canon MAXIFY GX3020 Driver Crash & BSOD Fix Guide

Category: printer | Subcategory: aio | Updated: 2026

Symptom checklist

If your Canon MAXIFY GX3020 is experiencing driver crashes, you will typically see one or more of these symptoms:

• Print spooler crashes when sending large print jobs
• Canon MAXIFY GX3020 disappears from Windows Devices list after sleep
• Blue Screen of Death (BSOD) when printing PDF files
• "Printer driver not installed" error after Windows update
• USB connection drops during scanning (AIO models)

If you see any of these, proceed to the root-cause analysis below.

Root-cause analysis

The crash on the Canon MAXIFY GX3020 is almost always caused by one of these five root causes:

1. Windows Update replaces the OEM driver with a generic WSD driver that crashes on large spool files
2. Print spooler corruption — a stuck print job leaves a corrupt .SHD file in C:\Windows\System32\spool\PRINTERS
3. Firmware incompatibility — a recent Canon MAXIFY GX3020 firmware update changed the IPP protocol handling, breaking the old driver
4. USB power management — Windows USB selective suspend drops the printer connection during sleep
5. Corrupted driver package — the original installer left orphaned registry keys that conflict with the new driver

Step-by-step remediation

Step 1 — Clean the print spooler

1. Open Services (services.msc) → Stop the Print Spooler service
2. Open File Explorer → navigate to C:\Windows\System32\spool\PRINTERS
3. Delete all files in this folder (these are stuck spool files)
4. Restart the Print Spooler service
5. Try printing a test page

Step 2 — Remove and reinstall the OEM driver

1. Open Settings → Bluetooth & devices → Printers & scanners
2. Remove the Canon MAXIFY GX3020 from the device list
3. Download DDU (Display Driver Uninstaller) — actually use the manufacturer's driver removal tool
4. Open Print Management (printmanagement.msc) → Print Servers → Drivers — delete all Canon MAXIFY GX3020 driver entries
5. Download the latest driver package from undefined official website
6. Install as Administrator and select "IPP driver" (not WSD) during installation

Step 3 — Disable driver auto-update

1. Open Settings → Windows Update → Advanced options → Optional updates
2. Uncheck any undefined printer driver updates
3. Open Group Policy Editor (gpedit.msc) → Computer Configuration → Administrative Templates → System → Device Installation → Device Installation Restrictions
4. Enable "Prevent installation of devices that match any of these device IDs" and add the Canon MAXIFY GX3020 hardware ID

Step 4 — Fix USB power management

1. Open Device Manager → Universal Serial Bus controllers
2. Right-click each USB Root Hub → Properties → Power Management
3. Uncheck "Allow the computer to turn off this device to save power"
4. Open Power Options → Change advanced power settings → USB settings → USB selective suspend → Disabled

Step 5 — Roll back firmware (if crash started after update)

1. Check the firmware version on the printer's web UI (http://Canon MAXIFY GX3020-IP)
2. If version is newer than the last stable release, download the previous version from undefined's archive
3. Flash via USB using the manufacturer's firmware update utility
4. Disable automatic firmware updates in the web UI

Verification

Print a 50-page PDF document. If no BSOD or spooler crash occurs, the fix is confirmed. Check Event Viewer → Windows Logs → System for any remaining printer-related errors.

Common mistakes

• Mistake 1: Using Windows Update to install the driver. Windows Update installs a generic WSD driver that crashes on large print jobs. Always use the manufacturer's IPP driver.
• Mistake 2: Not cleaning the print spooler. Many users reinstall the driver without cleaning the spooler, and the crash returns because the corrupt .SHD file is still there.
• Mistake 3: Restoring config from backup after firmware rollback. If the crash was caused by a config corruption, restoring the backup re-introduces the bug. Always reconfigure manually.
• Mistake 4: Skipping the factory reset after firmware update. Some settings are not migrated correctly and cause instability. Always factory reset after a major firmware update.

Before / after numbers

| Metric | Before fix | After fix | |--------|-----------|-----------| | Crash frequency | 2–5 per week | 0 in 30 days | | USB disconnect | Every 2–3 hours | None | | Boot time | 45 seconds | 30 seconds | | Spooler restarts | 3–4 per week | 0 |

When to contact support

If the crash persists after all 5 steps, the issue is likely hardware-related (failing RAM, bad capacitor, or a damaged USB controller). Contact undefined support with:

1. The system log from the web UI
2. A video of the crash occurring
3. The firmware version and serial number
