Canon 5B00 Ink Absorber Full: What Not to Reset Blindly
Understand Canon 5B00 ink absorber messages and why blind waste-ink counter resets can be risky.
The short answer
Canon 5B00 usually means the printer believes an ink absorber limit has been reached. Avoid blind reset utilities: if the absorber is actually saturated, resetting a counter does not remove waste ink.
Before you start
- Confirm the exact support code.
- Check whether your model has a serviceable absorber path.
- Compare repair cost with replacement cost.
What could be causing it?
- Waste ink counter reached limit
- The printer estimates ink collected during cleaning.
- Actual absorber saturation risk
- Ignoring absorber condition can risk ink overflow.
- Service-only design
- Many models do not make this a simple user part replacement.
A counter is not a container
The absorber catches waste ink. Resetting a number in software does not empty or replace it. That is why a “reset successful” message is not proof of a completed repair.
Work through these checks
- Copy the exact code and full Canon model.
- Open the matching Canon manual entry; similar support codes may have model-specific instructions.
- Stop repeated cleaning cycles, which add more waste ink.
- If Canon directs service, request a quote that covers the physical absorber work as well as any required service procedure.
What the result tells you
Compare the service quote with a replacement that meets your printing needs, including the supplies you would lose or need to buy. There is no universal percentage at which repair becomes a bad choice.
Do not treat another ink cartridge or a downloaded reset utility as the fix for a full absorber.
Worth avoiding
- Do not buy or download sketchy reset software.
- Do not reset service counters while ignoring absorber service.
