NOTE

If the old transfer unit was not at end-of-life when it was replaced (for example, if it was damaged), or if you want to continue printing past the end-of-life message, the transfer unit count must be reset using the printer control panel. Please note that the end-of-life message is provided as a customer service, and printing past it is likely to result in print quality degradation in the near future. Once the transfer kit count has been reset after an end-of-life message, feedback on the kit’s remaining life will be incorrect until the kit is replaced and the count is reset again.
