Use the model’s energy settings and remove avoidable print jobs from your routine.
Compare like-for-like energy data
Look at the manufacturer’s power figures and any applicable certification for the exact product. Printing, ready and sleep modes describe different conditions. Do not assume a lower active wattage alone means lower energy use over your working week.
Let sleep settings do their job
Check the available sleep and auto-off settings in the manual. Choose settings that fit your schedule, then verify the printer wakes as expected from essential devices. Some connected features may behave differently after a full shutdown, so test the actual workflow.
Reduce avoidable reprints
Preview documents, proof a page before a batch and choose two-sided output where suitable. These habits reduce wasted sheets and repeated jobs. When switching the printer off, use its power button and wait for the shutdown sequence to finish.
