- Okay, last sub lesson, it's all
about printer troubleshooting tools
and maintenance tools.
And this is gonna be a quickie.
I just wanted to talk about a couple
of the things you might want to use
with your printers.
And, you know, you have a printer like this.
This is an ink jet printer, and it's
a multifunction device but a device
like this can usually do about 10,000 pages
before you have to really maintenance it.
The laser printers, and I've historically been an HP guy.
I use a lot of the HP printers.
But it works essentially the same way
with other manufacturers.
These laser printers, they might be able
to handle 50,000 to 100,000 pages
before they have to be maintenanced.
Or, you might wanna maintenance the printer every year.
And so to do that you want to get yourself
a maintenance kit and, you know,
for HP printers, there's maintenance kits
for all their laser jets and everything that they make.
And so you can see down here, if we go to specs,
you'll see the average yield is 90,000 pages
once you install this and you know,
that's the yield when you first
start running the printer as well.
And it tells you what you get here,
you get a new roller assembly.
So you could change out those entrance and exit rollers.
A new separation pad, because you know
that can go bad over time.
A Mylar shield, and for example,
this printer has a Mylar shield.
If you were to open up the top
where you'd scan the documents,
there's a Mylar shield there that goes
across the length of the printer, and
that shielding is necessary when you have scanning going on.
So it comes with a Mylar shield as well
and an installation guide on how to work with all these.
And you might get additional stuff.
You might get additional rollers or pads
and other things but generally
this is what you get in your maintenance kit.
And if you're wondering about installing
any of this stuff, most manufacturers
of printers have very good forums
and a very good support page.
If you don't get an installation guide
or you lose your installation guide,
you can go to the website, you know,
for example the HP website, and it shows you
how to change out all these user replaceable parts:
separation pads, Mylar shields, a hard disc
if there is one, dims, et cetera.
So here you have the separation pads
step by step with images.
Roller covers, the Mylar shield, it's all here.
So if you're interested in doing any
of these things and maintenancing the printer,
go to the HP support center or whatever printer's
support forums or online documentation
and you'll get a lot of good stuff for that.
So the maintenance kit's really important.
You wanna do that generally with the printer,
a laser printer, every 50 to 100,00 pages.
It might be more, it might be 200,000.
You wanna check your documentation
and see how far your laser printer can go.
And the next tool is the toner vacuum.
And here's an example of one by MetroVac.
This is their DataVac Pro Series.
And this guy is high powered and meant to pull
out all the tiniest little pieces of dust and debris.
If you've ever seen toner spill out,
it just gets everywhere and it's so tiny
that it's very difficult to pick up even
with a regular vacuum.
So you use something like this
and you can also use this to clean the insides
of computers and the inside of the printers
and you know electronic equipment,
as they say, that's sensitive to dust.
They use specially tipped tools here
so you won't damage your computer system
even if you touch something by accident,
and you won't send a shock through the components.
That's what's important.
And that's why I usually say don't use a vacuum.
And what I mean is don't use a regular old vacuum
to vacuum out your printer or your computer.
You want to use something proper for that,
that has been designed to be powerful enough
yet safe enough to use on there.
But you still wanna be real careful
when you do use these.
Keep in mind devices like this
might go for two or 300 bucks.
So that's something else to look for.
This is a great troubleshooting tool.
Get all that toner outta the printer
and you'd be amazed how much better it works.
And with a tool like this, which super filters it,
it doesn't get all out into the air,
into the atmosphere. Very important.
I would still recommend doing this outside,
but you do what you can do.
And the other tool that (indistinct) talks about
in the objectives is the compressed air.
And we showed the compressed air before.
You wanna have compressed air to blow the stuff
out from the crevices where you can't really get
to with the vacuum.
So you blow the stuff out and then you
can vacuum it out with your special vacuum.
And that's a good way of keeping everything clean.
And this is a especially important
in dirty environments, warehouses, in places
that may be kitchens, or storage spaces,
or basements, you know, this is where
it's gonna be really important
to use these types of tools.
So make sure you have your compressed air,
make sure you have your DataVac, you know
for your computers and your printers.
And you can even use this on the inside
of your mobile devices and laptops
if you're real careful, you can see
they give you different attachments for that.
And of course your maintenance kits
for your printers, that's, you know,
the best thing to do, to avoid troubleshooting
in the future, the best thing to do
is to maintain your equipment.
Take care of your stuff and the maintenance kit's
the best way to do that for the printer.
So that's it for this sub lesson
and that's it for the lesson on printer troubleshooting.
And that pretty much wraps up the course.
So I hope you enjoyed it.
I'm Dave Prouse, and we'll do a wrap up
after this, but I hope you enjoyed everything,
and good luck to you with the exams.
