Inside every Canon inkjet printer, there is an absorbent sponge pad that catches excess ink during cleaning cycles. Canon programs a hard counter into the EEPROM chip. After a certain number of prints (usually 3-5 years of normal use), the counter hits 100%. The printer shuts down to prevent ink overflow.
The ST 5510 Resetter forces this counter back to zero (0%), allowing you to continue printing.
Q: Is the ST 5510 permanent? No. Resetting the counter does not physically clean the waste ink pad. If the pad truly leaks, you must replace it. Otherwise, the error will return after another ~5,000 pages. A: Yes, but you must run it in
Q: Can I use the ST 5510 on a Mac? No. It is Windows-only. Use a virtual machine (Parallels/VMware) or borrow a PC.
Q: Is it illegal to download this tool? Technically, distributing service tools violates Canon's copyright. However, individual use for your own printer generally falls under fair use in most regions.
Q: My printer model isn't listed. What now? Search for a newer tool (ST 6600 for models up to 2019, ST 7700 for 2020+).
