When your Canon imageCLASS LBP122dw orange light flashing pattern appears on the status indicator, it signals a specific hardware or consumable issue that needs immediate attention. Unlike a solid orange light which typically indicates a simple warning, a flashing pattern on this monochrome laser printer usually points to toner problems, paper jams, cover issues, or internal errors. This guide walks you through precise troubleshooting steps to diagnose the flash pattern, resolve the underlying cause, and restore normal printing operation quickly.
Understanding the Orange Flash Pattern
The imageCLASS LBP122dw uses distinct flash sequences to communicate problems. Count the flashes: two flashes typically mean no paper or paper jam; three flashes indicate a toner cartridge installation error; four flashes signal an open front or top cover; five flashes point to a toner cartridge memory chip issue; and continuous rapid flashing often indicates a more serious internal fault requiring printer repair assessment.
Troubleshooting Steps for Canon imageCLASS LBP122dw Orange Light Flashing
1
Check and Clear Paper Jams: Turn off the printer and unplug it from power. Open the front cover by pressing the release button on the right side. Remove the toner cartridge and carefully inspect the paper path. Check the rear cover (open by pulling the tab at the back), the output tray area, and the manual feed slot on top. Remove any crumpled, torn, or misaligned paper with both hands to avoid tearing. Reinstall the toner firmly until it clicks, close all covers completely, and power back on. The Canon imageCLASS LBP122dw orange light flashing should stop if a jam was the cause.
2
Inspect and Reseat the Toner Cartridge: Open the front cover and remove the Canon 069 or 069H toner cartridge. Gently rock it side-to-side five times to redistribute remaining toner—do not shake violently. Examine the drum surface for scratches or lines; replace if damaged. Clean the electrical contacts on the cartridge and inside the printer with a lint-free cloth. Ensure the memory chip on the cartridge isn't damaged or dirty. Reinsert the cartridge at a slight upward angle, then press down until the green lever locks into place. Close the cover firmly. This fix printer step resolves most three-flash and five-flash errors.
3
Verify All Covers Are Fully Closed: The LBP122dw detects even slightly ajar covers. After any internal access, press firmly on the front cover until you hear a distinct click. Check that the rear cover snaps flush with the chassis. Confirm the output tray extension isn't obstructing the top sensor. If the four-flash pattern persists, inspect the small plastic tabs on each cover that depress the interlock switches—these can crack and fail to trigger the sensor, requiring replacement. This is a common troubleshooting point that users overlook.
4
Replace Low or Empty Toner: If the orange light flashes slowly (once every 1.5 seconds), toner is genuinely depleted. The LBP122dw uses Canon 069 standard-yield (1,200 pages) or 069H high-yield (2,100 pages) cartridges. Install a genuine Canon replacement—third-party cartridges frequently trigger chip recognition errors causing the Canon imageCLASS LBP122dw orange light flashing pattern to continue. Remove protective tape from the new cartridge, install it completely, and wait 30 seconds for the printer to initialize and recognize the new supply.
5
Perform a Hard Reset and Firmware Refresh: With the printer on, press and hold the power button until all lights extinguish (about 10 seconds). Unplug the power cord from the wall outlet, not just the printer. Wait a full 60 seconds to drain residual power and clear temporary memory errors. Reconnect power directly to a wall outlet—avoid surge protectors which can cause voltage irregularities. Power on and observe the startup sequence. If flashing resumes, connect via USB to a Windows PC and use Canon's Printer Management Tool to check for firmware updates, as outdated firmware can cause false error states. Our printer support team frequently resolves persistent flashing errors with this method.
6
Check for Internal Hardware Faults: If rapid continuous flashing persists after all previous steps, the fuser unit, laser scanner unit, or main controller board may have failed. Listen for unusual grinding noises during startup, which indicate a failing fuser or drive motor. Check for error codes in Canon's PRINT Business app if wirelessly connected. At this stage, professional diagnostics are recommended—continued operation risks damaging additional components. Document the exact flash pattern count and duration before contacting tech support for expedited service.
⚠️ Important: Never force covers closed or use tools to pry open stuck compartments—this damages sensors and voids warranty coverage. Avoid using compressed air inside the printer; it drives debris into the laser optical path and causes permanent print quality defects. If your printer is under warranty (typically one year for the LBP122dw), attempting internal repairs yourself may invalidate coverage. Always power down and unplug before any internal access.

What does two orange flashes mean on the Canon imageCLASS LBP122dw?
Two orange flashes indicate a paper-related issue: either the paper cassette is empty, paper isn't feeding properly, or a jam exists in the path. Check all sources including the manual feed slot, remove and reload paper with proper alignment, and ensure the paper guides are snug against the stack without bending the edges.
Can I continue printing when the orange light is flashing slowly?
Slow flashing (approximately every 1.5 seconds) means toner is critically low. You may get a few more pages by removing and redistributing toner, but print quality will degrade rapidly with streaks and fading. Replace with genuine Canon 069 or 069H toner promptly to avoid damage to the drum unit, which costs significantly more than the cartridge itself.
Why does the orange light keep flashing after I installed a new toner cartridge?
This usually happens with non-genuine cartridges that have incompatible or defective memory chips. Remove the cartridge, verify you pulled all protective tape and packaging, clean the chip contacts with a dry cloth, and reinstall firmly. If flashing continues, the cartridge is likely incompatible—return it and use Canon genuine supplies. In rare cases, the printer's cartridge detection sensor requires professional cleaning or replacement.
