Question
A customer asked how to clear the "ink absorber full" message on a Canon TR4650. They wanted to know whether BCH Technologies sells a reset method or tool for this issue.
Answer
Understanding the "Ink Absorber Full" Message
Canon printers-including the TR4650-use internal waste ink pads to collect excess ink from cleanings, purges, and maintenance cycles. Once the printer believes the pads have reached capacity, it locks all printing and displays a message such as:
-
"Ink absorber full"
-
"Support Code 5B00 / 5B02 / 1700" (varies by region and model)
The printer cannot resume operation until the counter is reset using a service tool, and in some cases the waste pad must actually be cleaned or replaced.
Resetting the Canon TR4650 Ink Absorber
Canon does not provide an official reset method to end users. Instead, technicians use specialized Canon Service Tools designed to reset the waste ink counter for supported models.
You can find these tools online. The best approach is:
1. Visit eBay and search for "Canon Service Tool."
Here is the recommendation you referenced:

2. Choose the newest version available.
Every new service tool version typically expands support to more recent printers. Older tools may not support the TR4650.
3. Ask the seller whether their tool supports the Canon TR4650.
Compatibility is essential. The seller should be able to confirm this or provide a list that includes the TR4650 series.
4. Important Notes
-
These tools are often third-party or gray-market utilities. Use at your discretion.
-
Resetting the counter does not physically clean the pads. If they are truly saturated, ink may eventually leak.
-
If you continue to use the printer heavily, consider replacing or cleaning the waste ink pads to prevent overflow.
We do not sell these reset tools directly, but eBay vendors commonly carry them.
