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.

7.Press to select RESET SUPPLIES.

8.Press to highlight NEW TRANSFER KIT.

9.Press to select NEW TRANSFER KIT.

10.Press to highlight YES.
