Recommendation
We recommend that the default settings should be kept.
• If the customer requests that these settings should be changed, please explain that their energy costs
could increase, and that they should consider the effects on the environment of extra energy use.
• If it is necessary to change the settings, please try to make sure that the Auto Off timer is not too long.
Try with a shorter setting first, such as 30 min., then go to a longer one (such as 60 min.) if the customer
is not satisfied.
• If the timers are all set to the maximum value, the machine will not begin saving energy until 240
minutes has expired after the last job. This means that after the customer has finished using the machine
for the day, energy will be consumed that could otherwise be saved.
• If you change the settings, the energy consumed can be measured using SP8941, as explained below.
