Printer Error Code? Here's How to Decode and Fix Printer Error Messages

1. The "Paper Jam" Error Codes (13.xx, E3, E05)

Your printer displays Error 13 (HP), E3 (Brother), or E05 (Canon). These all mean the same thing: paper is stuck somewhere in the printer. But the specific number after the code tells you where the jam is located.

The Fix: Turn off and unplug the printer. Open all access doors—input tray, output tray, rear panel, duplex unit. Look for the specific location code: 13.01 = input tray, 13.02 = output area, 13.03 = rear access, 13.04 = duplex unit. Pull paper forward (in feed direction), never backward. Remove all torn fragments. Close doors and restart. If error persists, check for hidden fragments behind rollers.

2. The "Low Ink/Toner" Warning Codes (50.xx, E4, E16)

Your printer shows Error 50 (HP), E4 (Brother), or E16 (Canon). These indicate low or empty ink/toner cartridges. However, some printers incorrectly report low ink when cartridges are actually full—especially with third-party cartridges.

• Check Actual Levels: Remove cartridges and visually inspect ink levels (inkjet) or shake toner cartridge (laser) to redistribute toner.
• Reset Ink Levels: Some printers allow resetting the ink level counter. Access service menu (check manual for button combination) and look for "Reset Ink Levels" or "Cartridge Reset" option.
• Replace if Genuinely Low: If cartridges are actually empty, replace them. Use genuine cartridges to test if third-party ones are causing false readings.
• Clean Contacts: Dirty cartridge contacts can cause false low-ink errors. Remove cartridges and clean contacts with a lint-free cloth.

3. The "Print Head" Error Codes (0x97, E6, 0x97xx)

Epson printers show 0x97 or 0x97xx errors. Brother shows E6. These indicate print head problems—clogged nozzles, head not seated properly, or head failure.

Print head errors are common after periods of non-use, when ink dries in the nozzles and forms plugs that block ink flow.

The Fix: Run the print head cleaning utility 2-3 times (found in printer settings or maintenance menu). Wait 10 minutes between cleaning cycles. For Epson, try "Deep Cleaning" option if available. Check that print head is properly installed—remove and reseat it. Perform print head alignment after cleaning. If error persists, the print head may need professional cleaning or replacement. For Brother, check for "Print Head Reset" in service menu.

4. The "Connectivity" Error Codes (79.xx, E5, Printer Offline)

Your printer shows Error 79 (HP), E5 (Brother), or simply "Printer Offline". These indicate connection problems between your computer and printer—USB disconnected, Wi-Fi lost, or driver issues.

The Fix: For USB printers: Check cable connection at both ends, try a different USB port, replace cable if damaged. For Wi-Fi printers: Verify printer is connected to network (check printer display for Wi-Fi status), ensure computer and printer are on same network, restart router if needed, reconnect printer to Wi-Fi. For driver issues: Update printer drivers from manufacturer website, restart print spooler service (Windows: Services → Print Spooler → Restart), set printer as default, check printer port settings.

5. The "Fuser" Error Codes (50.xx, 59.xx, E8)

Laser printers show Error 50 or 59.xx (HP), E8 (Brother). These indicate fuser unit problems—the component that heats up to 400°F to melt toner onto paper. Fuser errors often mean the unit is overheating, not heating properly, or needs replacement.

The Fix: Wait 15-30 minutes for the fuser to cool down—it gets extremely hot. Turn off and unplug the printer. After cooling, power cycle: unplug for 30 seconds, plug back in, turn on. If error persists, the fuser unit may need replacement (usually after 100,000+ pages). Check for paper stuck in fuser area—this can cause overheating. For HP Error 59.xx, the specific number indicates the fuser problem type—check HP's error code guide. Fuser replacement requires professional service on most models.

6. The "Waste Ink" Error Codes (0xEA, E16, Waste Ink Full)

Epson printers show 0xEA errors. Canon shows E16. The message says "Waste Ink Full" or "Ink Pad Full." Inkjet printers have a waste ink pad that absorbs excess ink from cleaning cycles. When this pad fills up, the printer stops working to prevent ink overflow.

The Fix: This error requires resetting the waste ink counter. Access your printer's service mode (check manual for button combination—often involves holding buttons during power-on). Look for "Waste Ink Counter Reset" or "Ink Pad Counter Reset" option. Warning: Only reset if you've actually replaced the waste ink pad or had it serviced. If the pad is genuinely full, it needs replacement (usually requires professional service). Resetting without replacing can cause ink overflow and damage. For Epson, you may need service software to reset the counter.

7. The "Service" or "Maintenance" Error Codes (79.xx, Service Required)

Your printer displays Error 79 (HP) or "Service Required" message. These indicate the printer has reached a maintenance interval or a component needs service. Common triggers include page count limits, worn parts, or detected hardware issues.

The Fix: Check your printer's page count—many printers require service after 50,000-100,000 pages. If you've reached a maintenance interval, schedule service. For HP Error 79.xx, the specific number indicates the service needed—check HP's error code database. Try power cycling the printer first (unplug for 30 seconds). Some "service" errors can be cleared by resetting maintenance counters in service mode (check manual). However, if components are genuinely worn (like fuser, rollers, or print head), professional service is required. Don't ignore service errors—they can lead to print quality issues or printer failure.
