Quick answer
Canon 1682 and related 168x codes point to cartridge recognition, placement, or compatibility. The fix is usually seating or exact-supply matching, not a random replacement. Start with reversible checks, capture the exact model and wording, and verify the model-specific support page before buying parts.
Before you buy
Use these checks to avoid the most common wrong-part detours.
- Buy one correct replacement only after reseating and compatibility checks.
- Do not buy a printhead unless a separate printhead code appears.
- Prefer seller listings with exact Canon cartridge numbers and return terms.
Step 1
What this code usually means
Canon 1682 and related 168x codes point to cartridge recognition, placement, or compatibility. The fix is usually seating or exact-supply matching, not a random replacement.
The likely bucket is ink cartridge recognition. That bucket is a starting point, not a substitute for the exact model manual.
Step 2
Safe first checks
Work through the lowest-risk checks first. Stop before service-mode resets, chip bypasses, unsupported disassembly, or repeated cleaning cycles.
- Identify which cartridge or color is named.
- Remove and reseat it through the normal replacement path.
- Check that protective tape is removed and contacts are clean and dry.
- Confirm the cartridge number matches the model and region.
Step 3
Stop warnings
These are the points where a cheap-looking fix can become a damaged printer, leaked ink or toner, lost warranty path, or unsafe repair.
- Do not scrape contacts or modify chips.
- Stop if ink leaks from the cartridge.
- Avoid supplies marketed around firmware bypass.
