- [Instructor] All right.
Part two of troubleshooting common printer issues.
And you can see here, we have an error code.
You gotta look for error codes.
If there's a specific error shown on the printer's LCD,
read it and understand it.
Now, back in the day, they had these crazy codes,
like you know, PC load letter and stuff,
and it was pretty cryptic to put it nicely,
but now the messages are so, they're such plain English,
and they're so easy to understand that, you know,
usually it'll tell you exactly what the error is
and how to fix it.
And on some printers it might be an error number,
and you have to check your printer's documentation
to find out what the error means.
But here we see an error message.
Wireless will not work
with an ethernet cable connected to the printer.
To use wireless, remove the ethernet cable first.
So a lot of printers out there,
especially multifunction printers,
they can either use wireless or wired connections.
You can't use both.
And why would you wanna use both?
Not really necessary because if your printer's connecting
in a wired format out to your SOHO router or your switch,
then you most like, if you have other devices
that are using wireless, you know,
you most likely have some type of wireless access point
that connects to that switch as well.
So one or the other is fine.
And the reason this came up is because I connect my printers
with a network connection, a wired network connection,
so that I can limit the amount of wireless in my lab,
so I don't have as much interference.
And what I did was I just went to the settings and tried
to set up a wireless network.
And it tells you right off the bat.
Wireless will not work when ethernet cable is connected.
So read the error message.
It'll probably tell you exactly what the issue is.
And again, use your printer's documentation,
either in print format or online to find out more.
You might get specific messages like out of memory errors,
or low memory message.
And so these are important.
You'll see these quite often.
And you wanna check, first of all, the RAM.
First of all, you wanna check
whether the user's computer is spooling documents.
The setting with the least chance
of this error happening
is the start printing immediately spool setting.
And if we go to our devices and printers here,
and go to this printer and right-click it,
and go to printer properties,
and go to the advanced tab, we'll see
that the radial button for spool print documents
so program finishes printing faster is selected,
and the option is to start printing immediately.
That's the default in Windows,
and it's the best way to reduce the chances
of an out of memory error.
If you have it set to start printing
after last page is spooled,
then everything is spooled,
and then everything is sent to the printer.
worse than that, is printing directly to the printer.
And then the whole file just goes right
to the printer with no spooling whatsoever.
And, you know, in that case you better have a lot
of RAM on your printer.
So in some cases, the printer's RAM itself might need
to be upgraded.
And whenever installing RAM to a printer,
take all the same precautions you would
when working on a PC.
So, you know, but always check that spooling.
Whoever's having, whoever created that issue
on the printer, you know, the message shows up
on the LCD on the printer, but whoever created that issue,
whoever did the actual last print job,
check their spooling on their system.
So you could take advantage of the power of Windows,
and that desktop computer.
And finally, no image on the printer display whatsoever.
If you have no image here,
well you wanna check your connections.
You wanna check if the printer is in sleep mode
or off altogether and check the power cable.
In rare cases, there's an internal connector,
a flex cable that connects this display
to the main circuit board, the PCB in the printer.
So watch out for no image on a printer display whatsoever.
And so that's about it for this portion
of the troubleshooting for printers.
Error codes, the LCD, it can tell you a lot,
and make sure you use the documentation
for the printer as well.
And so that ends this sub lesson.
