Troubleshooting Printers Part 1 Welcome to Cybrary IT's A+ course. Today's lesson covers printers and how to troubleshoot common printing issues. Some of the most common problems users have with the quality of their print jobs is streaking, which are lines on the print job that are not supposed to be there, fading where the images are not completed, and ghost images where there is no print out put but instead only a hint of the image if anything is there at all. Low toner supply, poor paper quality or incorrect paper type, incorrect user settings, memory or residue on the drum are some example of why users experience fading or ghost images for their print jobs, or the toner wont fuse to the paper. We discuss in great detail how to troubleshoot and identify each of these events and what you can do to resolve it.

Hi and welcome to Cyber Dad. I t. My name's Anthony and I'm your local subject matter expert here for a plus. And today we're gonna be troubleshooting printers. So we're trying to print from a printer. What are some of the issues that we can run into? Well, one of the issues that we may run into with our print
00:18
print quality print out is streaks. Now streaks air when we have a printout and of cross our page or streaks of color or lines that aren't supposed to be there essentially, well, these streaks, maybe just a low printer quality. It may just be a lower in printer, and these the
00:37
doesn't have a very good, high quality print outs.
00:39
Or it may just be a low printer quality that we set in order to try to save some ink, maybe on our printer preferences on our computer. We said that we wanted this to be a low quality print out, and as such, the there's gonna be a little bit of streaking. We may have low are blocked toner on this lower block. Toner is causing these streaking.
00:58
Or we may have some dirty copier strip.
01:00
If This was a document that we placed into our copier tray or in order to copy it, or if this was a document that we scanned, then there may be a dirty copier strip that was causing these streaks to appear that weren't on the original document. And these streaks are actually our printer.
01:19
Our printer itself is functioning properly. Fine is printing what it's seeing
01:25
from it's from the scanning strip, but the scanning strip itself is just dirty. Next we have our faded prints. Now faded prints are when, as as it sounds like, we're printing out a document and the color is faded or the images fade, and it's hard to see well, this
01:42
it's typically an indicator of a low
01:46
ache or toner supply. Now this low ink or toner supply because it's running out, it's putting less on the page, and because it's putting less on the page, we're getting a faded image. This is simple to replace. Will just need to order more toner, order more ink and replace it with our in cartridges. We may also have the dried ink in the nozzles.
02:04
If there's dried ink and our print nozzles, these may be preventing ink from coming out,
02:08
and they simulate what it would look like if we had a low ink supply. But we replace our ink cartridges, and we're still having some issues with dried inks in the novels. This may be because we didn't probably shut down our printer a couple times, and it didn't clean out the nozzles properly, so the ink dried in there.
02:25
But whatever the case, we want to check our manufacturer's specifications for our particular printer model and see how it recommends to clean this out. If this becomes an issue,
02:35
we may also be using the wrong paper, are wrong paper type may produce these faded prints. So we want to make sure again that depending on what type of print we have selected, whether it's a picture or whether it's just gonna be a document that we select, we have the correct paper selected. We don't use the wrong type of paper
02:53
picture paper, Oh, versus regular paper versus high stock paper.
02:58
We may also have a low quality setting, much like when we had some of our streaking. We may have a lower quality setting on our computer for what we're printing. While this may save ink, it does so in a way that simulates as if it was a faded print. So we want to go in and want to make sure that if we want a higher quality setting, we said it
03:16
in our printer options to be a higher quality setting rather than a low quality.
03:23
And then lastly, if we're using a toner Ah, a ah, a laser printer. Rather the laser. Maybe the laser may be failing in our printer. This laser isn't matching the image properly. It isn't preparing the image properly to be transferred over to our paper. So wanna check and make sure that that laser is functioning properly?
03:42
Next, we have ghost images. Now, ghost images on our paper are going to be,
03:46
uh we have images that seem like they're faded, ghostly images in the background that aren't what we printed on our page. These maybe from previous prints that maybe characters and maybe images that looked like a combination of different prints. So we want to figure out why we're getting these ghost images
04:02
now. These ghost images may indicate that we're not getting enough charge for my primary Corona
04:08
our primary corona is a function of our laser printer, which helps to charge our drum. Now, if we're not getting that, we're not getting enough drug charge on our drum. We're not transfer or not picking up and transferring our toner properly. Then we may get some of these ghost images
04:25
now. We also may have residual drum toner left on our drum
04:29
that's not being scraped off properly after our drum has gone and transferred an image to a page, and it's supposed to scrape off and discharge all of the toner from previous prints. If it's not doing this properly, if it's not correctly scraping it off and cleaning off our drum that we may get some of these ghosts images
04:46
similar to our drum, not correctly discharging.
04:49
If our drum goes and it transfers the image to our page and then it doesn't discharge correctly, then we're going to get We're going to get toner and incorrect spots on our next prints, so we want to make sure we go through and we check all of the different components of our laser printer in order. Thio, make sure that we're eliminating these ghost images
05:09
now. We have tone or not fusing to our page.
05:11
Now when we have toner that's not fusing to our page, this could be very obvious. We get a pronoun and we let it sit for a couple seconds, and then we start touching the print out and it's smudging a lot, or it's it's very obviously loose toner on the page.
05:27
Now this tone or not fusing to the page is a big problem because our image isn't going to stay there or what's going to smudge all over the place.
05:33
So when are toner isn't fusing? We may have a future that's not hot enough. Are Fuser Assembly may be getting old? Part of maintenance kits that we'll talk about later typically include a Fuser assembly to replace, because over time this Fuser assembly may not get hot enough, and thus the toner may not fused to the paper properly.
05:53
We may have paper this damp, so because the papers damp, it's not completely dry. Our toner isn't properly fusing to the paper. It's not adhering to the paper like our it's typically supposed to, because our fuser simply works best or laser printers work best when our paper is dry, and it's obviously not dance.
06:12
Then when it goes through a fuser, it'll defuse that
06:15
toner to our page properly. So we want to make sure that we keep our paper we stored in a dry ah dry, cool environment so it doesn't get damp.
06:23
And then, lastly, we have incorrect paper if we're running incorrect paper through our town through our toner laser printer. If we're running incorrect paper, there are Fuser assembly. Then it may not be heating up the toner to the proper temperature. In order to fuse that toner to the page, we may not have pride, the proper paper that a work in a laser toner on the laser printer. So we want to make sure that we're
06:43
our Fuser. Assembly is hot enough. It's working properly.
06:46
Our paper is in damp, and it's not the incorrect paper or running into issues with our tone or not fusing to the paper
