Read, reset and verify Canon TS8340a
- Use the USB connection and the model-specific service mode requested by WICRESETPRO. Wait for stable detection before continuing.
- Read the available waste ink counters in WICRESETPRO and wait for a completed result. A missing reading is not a zero reading.
- Waste ink counter reset is supported for this model. Select that operation and follow its preparation instructions in the app.
- For a supported full reset, enter your valid Pro reset key and start the operation. Keep the connection stable until the app reports the result.
- Restart only when instructed, then read the counters again in Pro to verify the outcome.
Once a supported printer is connected and ready, the reset itself can take about a minute. Installation and preparation can take longer.
Resetting a counter does not replace physical absorber maintenance.
Your reset key
Unused keys do not expire. After the first reset, you can reuse the key on the same printer for 24 hours. Unused units in a Multi-Key pool do not all expire when that printer’s reuse period ends.
Choose one Multi-Key with the purchased pool or the corresponding number of separate codes. Check the current product, price and currency in the store.
For the wider application feature set, see printer diagnostics and maintenance in WICRESETPRO. Functions shown there are model-dependent.
