Frequently Asked Questions
What does Canon error 5B00 mean?
Error 5B00 means the internal waste ink absorber pads are full. During cleaning cycles, excess ink is deposited onto these pads. When they reach capacity, the printer stops to prevent ink leakage.
Can I reset the waste ink counter myself?
Yes, using Canon’s service tool or specific button combinations during power-on. However, this only resets the counter — the physical pads are still saturated. If you reset without replacing or cleaning the pads, ink may overflow and damage the printer or surfaces below it.
Error still not resolved?
If the steps above did not fix the error, the issue may require professional service. Contact the manufacturer support line or visit an authorized service center near you.
