Printer Prints Unwanted Recurrent Horizontal Lines

[Ahsaniqbalkmc 0]

I have a samsung printer (Samsung Ml-1675) that I have used for quite a while now. I have been quite happy with it and it got the job done brilliantly until there was no more toner in it. Then I faced a problem (as discussed here; http://forums.xisto.com/topic/56929-flashed-custom-firmware-to-my-printer-is-it-legal/
'>Flashed custom firmware to my printer). In short, to avoid recurrent heavy maintenance charges, I flashed a custom firmware which makes me able to just put the toner in myself and continue the printing process without spending anything extra on buying counter chips and stuff...

 

But since I have done the DIY repairing process, the printer started to print unwanted horizontal lines on every print. Below is the picture of the lines:

 

 

 

As can be seen in the image, the page has horizontal lines at regular intervals. And this happens with every page I print, no matter whether empty or full...

A strange thing that might be helpful with the diagnosis is that when I print a completely black page, the horizontal lines appear to be less dark than the rest of the page.

 

I googled a few terms in hope of finding some solution. But unfortunately couldn't find anything valuable about the issue. I also tried cleaning the drum. When I opened it, there were black lines on the drum, which were easily removed by cloth. However, the first print after the cleaning process again contained those horizontal lines. After performing some more printing, I opened the drum again and there were again similar black lines on it. So something is causing the toner to stick to the drum in that specific are in that specific fashion.

 

I also tried to clean the rest of the printer both with cloth and an air blower, but this was of no use.

 

So any sugestions on what is causing these recurrent black horizontal lines and more importantly how to get rid of them would be hightly appreciated.

There is an update to the situation. Yesterday when I had to print about 50 pages I noticed something that I thing can help in diagnosis of the issue so I am sharing it here.

So when I printed the 50 pages, the last pages of them had these lines lightened out. I mean to say that these unwanted lines were very light in these pages. See image below:

 

 

 

As it can be seen in the image, the unwanted lines are very light and not so bothering (but they are still there I would love to get rid of them).

 

However, to confuse the situation further, after printing these 50 odd pages, I gave the printer some rest (about 30 minutes) and then I printed another page. To my frustration, the page again had the similar unwanted lines as the image in the first post of this topic i.e. the unwanted lines were again quite dark and very annoying.

 

So in summary, the lines become light when I do a lot of printing but when I just start printing, the first few pages have again these lines quite dark.

 

Anyone ?????

Clearly your printer needs repair.

A vital component has to be changed.

You should print a text, get the paper having these black lines, and bring the paper to a repair shop, the guy will see immediately what happens and will tell you how much repairing will cost.

Unfortunately, on some printers, repairing costs as much as buying a brand new one

oh.... Its such a bad news..... not only because I will have to spend extra to repair my printer now but also because my experiment with refilling the toner myself is likely to have caused it....

 

I would rather leave it like this for now.........

At least show the printout to a repair shop, in order to confirm my diagnosis...

I am not intending to visit a repair shop (at least as long as the lines are not too troublesome)... I was hoping for some less demanding solution to the problem...

Could be. Or could have been.

However, if I'm right, it's a hardware problem.

And a hardware problem only has hardware solutions.

There is an update to the situation (not un update really but some info that I thought might be helpful to the readers)

 

A few days back, the toner in the printer was finished i.e. the prints started to look shady and light and improper. So I decided to refill it. But keeping in mind this problem of recurrent horizontal unwanted lines, I decided to take benefit of the chance and throughly clean the printer inside out. So I cleaned the printer as much as it could be cleaned at every possible area including inside the cartridge.

 

Then I refilled with new toner (different than the previous one) to nullify the idea that somehow the toner was the culprit. After refilling, I cleaned the cartridge again from the outside again. But when I tried a print-out, the lines were again there.

 

So I am pretty much sure now that the cartridge is damaged in some unseen way. And as @yordan has mentioned, the only solution to it is a hardware one, the best of which appears to replace the current cartridge with a new one.

[yordan 10]

If replacing with a new cartridge solves the problem, that indicates that the problem was due to the cartridge.

However, if the problem is located somewhere else, changing the cartridge will repair nothing.

Of course, on my own printer, I use a new cartridge as soon as the old one has no more toner.

Cartridges are expensive here.. Sometimes to the point that it is better to buy a new printer rather than a replacement cartridge.. And this is the reason I am currently sticking to my current faulty cartridge... When it damages to a point that it can no longer be used, I would be tempred to buy a new printer rather than replacing it....
