Troubleshooting Printers Part 3 Now that we've identified issues with the devices and their components, let's look at other problems uses have with printers. Garbled characters occur frequently and often the issue is printer driver or the printer not being in a ready state to receive print job so it wasn't processed from the print queue which may simply require reinstalling the printer driver. Jobs backed up in the print queue is another issue and a given when large number of uses print to a single device. Other issues examined include low memory error, not having the correct permission to use a printer, vertical lines which indicate toner/drum transfer issues.

So what might be going on if we're having an issue like garbled characters? Well, if we have garbled characters, a k we're printing out a print job, but we're printing out a picture or a text document, and all we're getting is a whole bunch of
characters that don't really make any sense. Well, this might be a printer driver issue or an issue with our installation. This is typically an indicator that when we print when we tried to install a printer, or when we updated the driver or in sold the driver, there was an issue with the communication with
between our computer and the printer. And it's just printing out all these random characters because
that's what it thinks it's supposed to print out and also may mean that the printer is not ready to start receiving print jobs. We may wanna power cycle the printer. We may want to disconnect to reconnect our printer or these don't solve our. If this doesn't solve anything, or if this is the first time we've printed from this printer and we're getting these garbled characters,
then we may want to re try uninstalling and reinstalling our driver or re running our installation of our printer.
Next we have our vertical lines are vertical lines are a little bit different than our streaks are. Vertical lines are gonna be blank white or black lines that go across our page. They look really neat, but they they're meat as in they're not crazy streaks. They're very straight lines,
but they aren't what we want on our page.
Well, these may be due to a dirty transfer Corona. When our laser printer is trying to go through and is actually trying to trance
perform the process of transferring to our page, there may be a dirty transfer Corona that's causing those lines. We may also have a blocked laser or debris in our toner cartridge. That's not properly placing the toner on there on the drum before being transferred to our page.
So somewhere, along with our dirty transfer corona or blocked laser or debris on our toner cartridge,
there may be an issue with transferring the pate the toner to the drum or transferring from the drum to the page.
So following our manufacturer specifications, we may want to go in, and we may want to try cleaning our transfer Corona or replacing it. Or we may want to try cleaning up some of the debris that may be in our toner cartridge or replacing our toner cartridge. Next, we have our backed up print queue. Our back that print, too.
A lot of people have experienced this before. You're trying to print,
Ah, certain print job to a printer, and you noticed that nothing's happening. It's just backing up in the print queue. You see what what's in line to be printed, and there's a lot of different documents, either from just tur from you in a couple of the people and they're not going through Well, this may mean that there's a stuck
print job. There may be a print job that took up a lot of memory or print job.
Ah, that didn't format properly or with having an issue in the printer. And it's just stuck there at the end of the key or at the beginning of the Q. Rather so nothing else is pushing able to push through because that job is just stuck there. Well, we may want to try restarting the prints schooler, clearing out everything and re starting from scratch and that they helped to push that out.
Ah, and help us to restart her printer
prints puller and get that through our get that stuck print job through.
This may also be an indicator of a driver mount function, so we may want to check and see what driver we have installed for this printer and see if we need to do any updating or rolling back or re install a new driver.
And this also maybe something as easy as it's out of paper or the printers off if the printer's out of paper or the printer's office not able to process the print jobs that Aaron Que that are waiting to be printed out. So we may need to go to the printer physically, put in more paper or turn. The prints are on,
and this may allow jobs are processing jobs to start printing through, and then we'll get jobs pushed through.
Next, we have, ah, low memory error. If we receive a low memory error on our printer, that essentially means that our printer is prince. Her memory is probably full. It may have received a very large single job or multiple successive jobs that have filled up. It's temporary memory on the printer that allows it to spool up and print certain jobs.
So what we may need to do is just power. Cycle our printer and clear out that printer memory in order to
clear out that air message. And we may want to consider breaking up our print jobs, not sending such large print jobs at once to the printer in order to prevent having that printer low memory error again. Now we have an access denied message. Now this access denied message, maybe simply invalid credentials.
We're trying to connect to the printer, and we don't have the permissions necessary on our domain or on our network to connect to this printer.
We may have a driver malfunction issue. We may be trying to print to this printer and is giving us a access denied, but really, it's more of a driver issue than not having the proper credentials.
We may just need to reinstall the printer, so if we're getting this access denied message and this isn't this isn't the first time we've connected to this printer. This isn't the first time we've printed to this printer. We know we have the proper credentials. We know something else must be going on that we may want to try taking that driver. I'm installing the driver or uninstalling our printer entirely
and then re installing it to get rid of that access, denied message and being able to print our jobs.
Now we have The printer just won't print well when a printer won't print. There could be a lot of different connective ity and prints or malfunction issues that are going on, but we noted down to a couple couple main ones. One of our main are some of our main ones is that our printer isn't plugged in or turned on, so we need to make sure that our printer is plugged in or and turned on.
We also want to make sure that it has paper in the printer,
and it also has toner, and it's not completely have toner. We need to make sure that it has connective ity. If it's not, if our printer isn't printing, it may not be receiving any connections from our from our computer. If we are plugged in using a USB cable, we want to make sure that our U. S. B cable is secure.
If we're connected to our network, we need to make sure that all of our cables are plugged in and we're plugged in and that our network is functioning properly.
And if we're connected wirelessly, we need to make sure that we have the correct wireless credentials in our printer. We have the correct and we have the correct key in our prints are for our wireless network and all the other required information and war to connect to our wireless network.
We also want to make sure that our prints schooler isn't spot stuck. We talked a little bit about why we may have a backup prince print queue, and sometimes our local print spolar might be stuck. And when this occurs, we won't be able to print anything. So we may need to do a restart of our prints. Polar or were Were you accessing a
share printer on a server? We may need to restart the Prince Bowler on the server
in order to clear out these backed up jobs and be able to start printing again.
And then we have an invalid print driver or insulation. If we have never been able to print to this computer printer before, and we're just starting to try and print now. Then we may have improperly installed the printer in the first place. Or this may not be the right driver for the printer or if we updated driver. This new updated driver may not be working properly,
so we may need to do a re installation of the printer. We may need Thio
roll back the driver or update the driver in order to print properly. So connectivity issues prints are being plugged in. Prints are having enough paper and toner print schooler stuck. Invalid print drivers, re installations, cables going bad network network components going bad wireless configuration,
are all possible reasons for a printer not printing. Next, we have the wrong color. Say we're printing a particular item or printing a particular picture, and the color isn't quite right. It's not what we were seeing on our screen. Well, this may be an indicator of low toner or dried ink.
The printer's trying to still print this image is trying to compensate using the other other colors, but it's not working properly,
or, in the case of dried ink, there may be a print, our print nozzle and ink nozzle that's dry that hasn't dried in it. So it's trying to print this particular color. It thinks it's printing these thoughts of color, but it's not. So we're getting wrong coloring on our print on our pronounce.
So we need to make sure that we check and make sure that we don't have low toner or Low Inc
and that are eight nozzles air clear, and they're able to be printed through that. They're able to spray the ink onto our page. We may just have a miss configured color on our printer are a lot of our printers. Allow us to do a color configuration. Allow us to do a test run that helps to configure the color on our printer.
Based on doing a test page,
this test age will run through. It will configure the color color and helped make the color a little bit more accurate for our printer. And then we'll try and run another print out of whatever page we were trying to print, and this will make up through a lot better. Also, remember that just that just our printer quality itself,
such as the quality that we select
not only in our settings on our computer, but also the qualities that we select when we buy. The printer also has ah lot to do with wrong coloring. If we buy a low in cheaper printer and then expect to print these really high dp I extremely,
extremely detailed great color print outs. We're going to be a little bit disappointed.
We need to make sure that we are doing our research. We're checking and see, seeing what the DP I capabilities are for this particular printer. What the color capabilities are for this particular printer before we try to use it to print on jobs that are going to be compatible.
Let's say we're trying to install our printer or we're trying to install a driver, and we're just getting an air that's not letting us even install our driver.
Well, this driver maybe not letting us install it because it may be a incorrect
32 bitter 64 bit version of the driver. If we're running a 32 bit operating system or 64 bit operating system will need to install the corresponding 32 bit or 64 bit driver the incorrect bit driver won't install properly or sometimes won't even let us install it at all.
We'll also need to make sure that we're installing the driver on the correct operating system and that the driver isn't already already installed on our operating system.
Ah, lot of drivers are operating system and hardware specific. So if we're trying to install a driver meant for a window 7 64 bit operating system, it's not gonna let us install on the Windows 7 32 bit operating system or even a Windows X P 64 bit operating system.
Just because it's not on Lee 32 or 64 bit specific.
But it's also operating system specific, so we need to make sure that we select the proper driver. We select the correct driver not only for 32 bit or 64 bit, but but obviously for our printer hardware, but also for our correct operating system that we're using to connect to the printer. And then, lastly, we have air codes
pretty much anything that we've covered
pretty much anything that we haven't covered. As faras printer errors go will have error codes for them now, not all of our printers will have in depth. They're all inclusive air codes. Some of our lower in printers may just have some air codes, which indicate that
there's a paper JM or that they're out of paper out of toner.
Or some of our higher in printers may be very specific that there's a paper jam in this compartment or that there's low paper in this tray. Or that there's some other serious issues with firmware or a network interface card or a particular network setting on our printer.
So we need to make sure that we check these air codes because they depend on the make and model of the printer,
and we
verify them with that particular manufacturer. We check that particular manufacturers, if we can make and model for their air codes to see what those particular air codes mean. These air codes may be a great help when we're used when we're trying to diagnose printer issues because Eric codes are,
I can maybe a bit more specific,
then just general connective ity or printer issues, so we can use those air codes in doing research, checking out forums, contacting the manufacturer in order to figure out what exactly may be going on with the printer. But again, remember, air codes, maybe making model specific. So always check with the manufacturer. Always check with
your manual in order to determine what a particular area code may mean.
