Summary of observations in Focus Group and follow-on comments:
Define state in terms of objective % of full operation power consumption
Defined power states in terms of time to come up to full operation
Need to be able to access config even in reduced power state
Providing good power consumption data vs ould units.
Reporting/ gathering statistics on basis on components/services/subunits
Manage power vs dashboard interface
Automatic policy setup on basis of history
Additional comments after the call.
From Steve Juiris
My take on this is that we need better more
standardized tools and information to show end
users what they are actually using with their
old devices and the new one.. This should allow
us to better present new devices in a MPS Solution
and also potentially allow us to show them power
use by state..
Example.. Your 30 printers consumed this much
energy by being in these modes for the last month.
Based on moving to these devices AND putting them
in to these various standardized states, you should
expect to see exactly this much power savings.
In MPS we can do this by printer type and toner
costs.. To bridge this with power in a seamless
fashion would be huge. To the comment about
integrating this into Print Fleet/Fm Audit type
of dashboard reporting/control dashboard is exactly
what I was thinking.
From David Burkill
You may well have got around to discussing these
topics, but I had a few points that I had hoped
to contribute to.
1/ Manufacturers should develop better, faster
"Instant - On" fuser heaters so that erratic workflow
can be managed more effectively
2/ Further development of programmable Timed Power
On facilities should be encouraged.
3/ Pull - Printing should be encouraged - and should
really be a de-facto standard - in all true Managed
Print Service offerings.
Not only does it have obvious waste control and
environmental benefits but if all manufacturers produced
systems that has embedded interfaces on all multi and
single function devices for the Corporate market, then
control of power usage would be enhanced.
4/ In the Corporate / Large Enterprise market I am finding
it increasingly essential to deliver some means of power
consumption management. This, I believe, is a key development
opportunity for manufacturers.
Controlling power - on scenarios is important, but my end user
clients are now demanding to understand their current power usage,
projected refresh power usage and - more importantly - continual
assessment of power usage even down to a metered level.
While I am aware of several manufacturers engaged in activities
around my first 3 points - I have no examples of any of them
providing this detail from any devices currently on the market.
From Josh Feathers:
1. It would be nice to have a list of factors that
impact power on print equipment and devices, and to
what weight those are impacted. As an example (fake numbers):
Suppressing blank pages: .025% reduction avg.
Turn off banner pages: .05% reduction avg.
Duplex default: .0003% reduction avg.
Sleep Time: 30 minutes: 20% reduction avg.
Sleep Time: 15 minutes: 21% reduction avg.
2. I would also say that anything you can do (even
use MORE power) to get a device up and running
(decrease warm-up time) would allow me as an end-user,
to feel more confident reducing my "Sleep Time" delay.
As an example, a large insurance company may have their
devices set to 30 minutes Sleep Delay as a default. If
the devices could change from Standby to ON in a lower
amount of time, I would change my settings from 30
minutes to 15 minutes.
