00:00:02
a multifunction device is an output
00:00:04
device that's commonly abbreviated as
00:00:06
mfd for multi-function device these
00:00:09
devices can perform many different
00:00:11
functions including printing scanning
00:00:13
they could be a fax machine because fax
00:00:16
is indeed still used even today network
00:00:19
connectivity phone line connectivity and
00:00:21
printing from the web from a
00:00:23
technician's perspective it's important
00:00:25
to know that these are complex devices
00:00:27
with many moving parts it's very
00:00:29
possible that you'll be spending at
00:00:31
least some of your time maintaining a
00:00:33
multi-function device a multi-function
00:00:36
device may not be the small device that
00:00:38
you might buy from an office supply
00:00:40
store and install at your home instead
00:00:42
it might be a much larger device that's
00:00:44
used in the enterprise these very often
00:00:47
will need to be installed in a
00:00:48
particular area with the proper amount
00:00:50
of power network connectivity and
00:00:52
accessibility so that everybody can gain
00:00:55
access to the system
00:00:57
to use one of these multi-function
00:00:58
devices you'll need the appropriate
00:01:00
driver installed in your operating
00:01:02
system so that it knows how to print fax
00:01:05
scan or perform any of these other
00:01:07
functions on that multi-function device
00:01:10
just as you would choose the correct
00:01:11
hardware driver for your operating
00:01:13
system you would choose the correct
00:01:15
print driver for your operating system
00:01:17
as well so for using windows 10 you
00:01:19
would get a print driver specifically
00:01:21
built for windows 10. you also want to
00:01:23
be sure you use the right version of the
00:01:26
print driver if you're running a 32-bit
00:01:28
operating system you have to use a
00:01:30
32-bit driver if you're using a 64-bit
00:01:33
operating system you must use a 64-bit
00:01:36
driver as you can probably see from this
00:01:39
explanation you can't really mix and
00:01:41
match drivers you have to make sure
00:01:43
you're using exactly the right driver
00:01:45
for exactly the right operating system
00:01:47
and version
00:01:49
most printers will be able to
00:01:51
communicate with your system using one
00:01:53
of two different printer languages one
00:01:55
is pcl or the printer command language
00:01:57
this was created by hewlett packard for
00:01:59
their laser printers but is used on many
00:02:01
different printers throughout the
00:02:03
industry you can see in this output that
00:02:05
we have a header at the very beginning
00:02:06
which specifies this is pcl output and
00:02:09
you can see the pcl is on the bottom
00:02:12
half of this document
00:02:14
another popular printer language is
00:02:16
postscript that was created by adobe
00:02:18
systems this is a printer language that
00:02:20
was originally designed for very
00:02:22
high-end printing and printing that was
00:02:24
done in print houses these days you'll
00:02:26
find postscript used on many different
00:02:28
types of printers that are used for many
00:02:30
different purposes to make things even
00:02:32
more complicated some printers can be
00:02:34
configured to communicate via pcl they
00:02:37
can also be configured to communicate
00:02:39
using postscript so you want to be sure
00:02:41
that the driver you're using matches the
00:02:43
configuration of the printer if it's a
00:02:45
pcl or pcl configured printer then you
00:02:48
want to use a driver that is a pcl
00:02:50
driver conversely if it's configured to
00:02:53
work as a postscript printer the driver
00:02:55
you should be using should clearly be a
00:02:57
postscript driver
00:02:59
for others to be able to print to this
00:03:01
multifunction device they need to be
00:03:03
able to physically communicate to that
00:03:05
system and one way to do this is over a
00:03:08
wire one of the very common ways to
00:03:10
connect to a printer is using usb or the
00:03:13
universal serial bus and one common
00:03:15
connector on a printer might be the usb
00:03:17
type b connector you would use type a on
00:03:20
your computer and it connects to the
00:03:22
printer with a type b interface the
00:03:25
other type might be an rj45 which is
00:03:27
commonly connected to an ethernet
00:03:29
network this allows you to print across
00:03:31
the network and you wouldn't need to
00:03:32
have any type of usb connectivity if you
00:03:35
look at the back of your printer you
00:03:37
might see multiple options available and
00:03:39
you can use the one that makes the most
00:03:41
sense for your implementation here's a
00:03:43
good example on the back of this printer
00:03:45
we have a usb type b connection and an
00:03:48
ethernet connection and in this
00:03:49
environment this user is chosen to
00:03:51
connect to the ethernet network
00:03:54
but of course you don't have to connect
00:03:55
to a printer over a wired connection you
00:03:57
could instead use a wireless connection
00:04:00
if you have a printer that's near your
00:04:02
location you might want to use bluetooth
00:04:03
but of course bluetooth does have a
00:04:05
limited range and if this printer is
00:04:07
down the hall a bluetooth connection may
00:04:09
not be the best choice instead you might
00:04:11
want to use 802.11 which is the wireless
00:04:14
network we might commonly use with an
00:04:16
access point we refer to the use of
00:04:18
802.11 in an access point as
00:04:21
infrastructure mode so that you can have
00:04:23
everyone in your local area use this
00:04:26
access point to be able to communicate
00:04:28
to this printer but you could also
00:04:30
configure wireless communication to be a
00:04:32
one-to-one relationship using 802.11 ad
00:04:35
hoc mode this means there's no access
00:04:38
point that would be used for
00:04:39
communication instead a single device is
00:04:42
able to communicate directly to that
00:04:44
individual multi-function device
00:04:47
now that we've installed our
00:04:48
multi-function device and we've
00:04:50
connected it either wired or wirelessly
00:04:52
we now need to allow other people to get
00:04:55
access so that they can print to that
00:04:56
printer and we would do that by sharing
00:04:59
the printer one way to do this in
00:05:01
windows is to create a printer share
00:05:03
this allows you to physically connect
00:05:04
the printer to the computer that you're
00:05:06
using and then you tell the computer to
00:05:08
allow everyone to print to this printer
00:05:11
through your computer here's the
00:05:13
properties window of a brother printer
00:05:15
that is directly connected to this
00:05:17
particular computer this user has gone
00:05:19
to the sharing tab and has chosen to
00:05:21
share this printer and has provided a
00:05:24
share name a brother
00:05:27
hl-l-8350cdw series anybody on the
00:05:29
network who would like to use that
00:05:30
printer would simply look for this name
00:05:32
and they can send their print jobs
00:05:34
directly to this printer share
00:05:36
one of the challenges with a printer
00:05:38
share on someone's computer is when they
00:05:40
turn that computer off everyone loses
00:05:42
access to the printer so instead of
00:05:44
using a printer share you might want to
00:05:46
use a print server this is usually
00:05:48
software that's running on the printer
00:05:50
itself which allows people to print
00:05:52
directly to the printer without needing
00:05:54
a third person's computer in the middle
00:05:56
jobs are queued directly on the printer
00:05:59
and if you need to manage delete or add
00:06:01
any jobs you could do that from the
00:06:03
management page of the printer itself to
00:06:06
provide this management there's usually
00:06:07
a web-based front-end on the printer
00:06:09
itself or there might be an executable
00:06:11
you install in your operating system to
00:06:13
be able to manage it through a client
00:06:16
when you send your print job to the
00:06:17
printer there are a number of different
00:06:19
options available one of these is the
00:06:21
duplex option this allows you to send a
00:06:23
print job to the printer and the printer
00:06:25
will print on both sides of the page in
00:06:27
order to save paper not all printers
00:06:29
have a duplex option but if it's
00:06:31
available in your printer you'll
00:06:32
probably see it listed on the print
00:06:34
dialog another option you might have is
00:06:37
to choose between printing in portrait
00:06:39
mode or in landscape mode in portrait
00:06:41
mode the page is longer from top to
00:06:44
bottom and in landscape mode it's turned
00:06:46
on its side and is longer from left to
00:06:48
right the paper itself isn't rotating
00:06:51
instead the printer is choosing how to
00:06:53
print to that paper based on whether you
00:06:55
set it to be portrait or landscape
00:06:57
on larger printers especially in a
00:06:59
workplace you may have the option to
00:07:01
choose a particular tray to print from
00:07:03
printers can have many different printer
00:07:05
trays and each tray might have a
00:07:07
different type of paper there might be
00:07:09
plain paper in one tray a letterhead and
00:07:12
another and a legal size paper in a
00:07:14
third you would choose the tray you'd
00:07:16
like to use when you're in the print
00:07:18
dialog and when you press print it will
00:07:20
pull that paper from the tray that you
00:07:22
specified sometimes you may have to
00:07:24
physically look at the printer trays to
00:07:26
see what paper is in which tray but you
00:07:28
might also be able to look at the
00:07:29
properties of the printer and see how
00:07:32
the trays have been configured by the
00:07:33
administrator this particular printer
00:07:35
has letter paper in tray 1 and envelope
00:07:38
number 10 in tray 2 there's legal paper
00:07:40
in tray 3. tray 4 has a larger envelope
00:07:43
a 9 by 12 inch and then tray 5 is a
00:07:46
bypass tray that has letter paper so
00:07:49
when you're printing you'll get the
00:07:50
option to decide what the paper source
00:07:53
might be you could have it automatically
00:07:55
choose the source but if you want to
00:07:56
choose a particular tray that might have
00:07:58
letterhead you can choose exactly which
00:08:01
tray applies to your print output
00:08:03
another option on many printers is to
00:08:05
set the quality of the printout that you
00:08:07
would like to use if this is a draft
00:08:10
print that will not be distributed you
00:08:11
may want to use a lower quality setting
00:08:14
than something that might be distributed
00:08:16
to others so you can set the resolution
00:08:18
of the output you can tell it whether
00:08:20
it's color or grayscale or you might
00:08:22
choose a color saving mode that will
00:08:24
print in color but it won't use as much
00:08:26
color as it might need with a non-draft
00:08:28
print
00:08:30
the reason we might want to limit how
00:08:32
much toner or how much ink we might be
00:08:34
printing is that the ink and the toner
00:08:37
is relatively expensive and if we can
00:08:39
minimize the use of that toner then we
00:08:41
can save money in the long run this also
00:08:44
means we might not want everyone in the
00:08:47
office printing to a printer that has
00:08:48
very expensive color output so we might
00:08:51
want to configure a printer with very
00:08:53
specific security settings that allow or
00:08:56
disallow someone access to that print
00:08:58
queue in windows you can do this in the
00:09:00
printer properties under the security
00:09:02
tab and you can specify individual users
00:09:05
or group of users and then determine
00:09:07
what access they might have to the
00:09:08
printer this printer gives you the
00:09:10
option to allow or deny access to print
00:09:14
manage the printer manage documents and
00:09:16
create special permissions
00:09:18
some printers might even allow you to
00:09:20
set security based on your id badge that
00:09:23
you use at work so when you walk up to
00:09:25
the printer you would simply
00:09:26
authenticate with the id badge and then
00:09:28
it will print the output this will
00:09:30
prevent your output from being printed
00:09:32
when you're not near the printer which
00:09:34
could potentially release sensitive
00:09:36
information to others
00:09:38
if there's problems with the printer
00:09:39
process then you may need to look at
00:09:41
some logs to help understand where the
00:09:43
problems may be occurring there are some
00:09:45
logs on the printer that are audit logs
00:09:47
this allows you to see exactly who
00:09:49
printed to the printer how many pages
00:09:51
were printed and what type of print was
00:09:53
used this might allow you to manage
00:09:55
costs better so you know exactly how
00:09:56
much toner or color you might be using
00:09:59
and you can see exactly who is printing
00:10:01
to this printer and be able to make any
00:10:02
permission changes based on that
00:10:04
information you might also be able to
00:10:06
see information in your windows event
00:10:08
viewer and there might also be logs that
00:10:10
are built into the printer itself
00:10:13
some printers also support a feature
00:10:14
called secured prints this is built into
00:10:17
windows where you can create a personal
00:10:19
identification number to protect any
00:10:21
printing this would be configured in the
00:10:23
print settings on your windows device
00:10:26
you would define a personal
00:10:28
identification number specific to you
00:10:30
and once you've sent your print jobs
00:10:32
nothing will print until you arrive at
00:10:34
the printer and put your personal
00:10:36
identification number into the console
00:10:38
of the printer itself at which time it
00:10:41
will print your output
00:10:43
our multifunction devices are not only
00:10:45
good at providing us with printed output
00:10:48
but we're also able to take these
00:10:49
printed pages and use them as input by
00:10:52
using the flatbed scanner that's built
00:10:54
into the multi-function device the
00:10:57
scanner allows the multi-function device
00:10:59
to read the information that's on the
00:11:01
page and then save that information as a
00:11:03
digital file this is often integrated
00:11:06
with an automatic document feeder so you
00:11:08
can take a large stack of papers slide
00:11:10
it into the scanner and then have it
00:11:12
scan each page individually one by one
00:11:14
without you having to manually change
00:11:17
the pages
00:11:18
with most multifunction devices you can
00:11:20
decide what happens with that scanned
00:11:22
image it might be a scan that goes
00:11:24
directly to your email or someone else's
00:11:26
email we could also scan to a particular
00:11:29
folder that may be on a file server with
00:11:31
windows this is done using smb or server
00:11:34
message block or you could send all of
00:11:36
this to a microsoft share that may be on
00:11:38
a centralized server and many new
00:11:40
multi-function devices can take that
00:11:42
scanned image and scan it to the cloud
00:11:45
it might move it to a google drive
00:11:46
account a dropbox account or any other
00:11:49
shared folder that you might have in the
00:11:51
cloud
00:12:02
you
