Over that last months, the problem has become worse.
HP Deskjet 6830 and 6840 - Streaks or Lines in the Printed Image
Each time I print, the first pages are covered with black, horizontal lines. I have changed the toner cartridge, run all cleaning and maintenance functions, and the problem still persists. Good Day. A warm welcome to the HP community.
I understand that you are getting black horizontal lines while printing and you have tried with different toners and done few troubleshooting steps.
Unlike ink printers, laser printers use heat to fuse a plastic toner to the surface of the paper. Decrease the fuser temperature setting. Use the archive print feature to improve toner fusing. If this does not resolve the fuzzy, dark print, or toner scatter issues, use a lower basis weight or thinner paper. Press the Power button to turn on the product. With the product turned ondisconnect the power cord from the rear of the product.
If the product does not turn on by itself, press the Power button to turn it on. Sandytechy20 I am an HP Employee. The explanation provided by Sandytechy20 is I believe the solution to my problem.
However, I work in a Mac environment. I believe I probably caused this problem when I attempted to print some things on card stock.
If you could please reply with instructions for resolving the issue, using a Mac, I would be so grateful.

Did you mean:. It has been a while since anyone has replied.It is particularly noticable on Cyan or Yellow areas of print. I've tried troubleshooting, have installed and followed HP Print and Scan doctor, which included realligning the print heads and cleaning them but the problem persists. The printer is nearly 4 years old and is in moderate use daily.
I use a lot of the Cyan ink because some logos I regularly print on my letterhead are blue. Is this just a case of a printer that needs a service? Is that even a thing? Is it past it's best or is there something obvious I could be missing? Any help would be greatly appreciated as my next step is to start hitting it with a hammer. I've tried turning it on and off. Hi AntW. Welcome to HP Forums.
This is a great place to get support, find answers and tips. As I understand, you're getting horizontal lines while printing. Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:. Does this happen while making a copy? When was the last time it worked fine? Let's try these steps from the link:. Step 1: Reset the printer.
To reset the printer, disconnect the printer from the power source, and then reconnect it. Turn the printer on, if it is not already on. Wait until the printer is idle and silent before you continue. With the printer turned ondisconnect the power cord from the rear of the printer. Unplug the power cord from the wall outlet. Wait at least 60 seconds. Plug the power cord back into the wall outlet. HP recommends connecting the printer power cord directly to the wall outlet.
Reconnect the power cord to the rear of the printer.
Why does my inkjet printer print with horizontal lines?
Turn on the printer, if it does not automatically turn on.Providing Quality Cartridges Since Horizontal lines across prints are most commonly experienced with inkjet printers and are usually down to a partially blocked printhead.
Such an issue can easily be resolved with a bit of basic maintenance. If a slight blockage is present you will notice breaks in your prints as the printhead moves from left to right dispensing ink.
These lines will be in a regular pattern and usually run consistantly down the length of the page as demonstrated below. Looking at this image it may not be evident that the gaps in this text form a regular patten. It is particularly difficult to identify a partially blocked printhead when only printing black and white text as only a single colour ink is being used and gaps also appear naturally. To demonstrate what I mean clearly I have marked in red on the same image where the lines are occurring.
Conversely, printing colour images or photos presents an entirely different issue as it is not always evident which colour is at fault. This is because your printer combines two or more inks when creating almost any colour, making determining or even describing the fault a challenge.
Take a look at the image below for example. However what you are actually looking at with these lines is an absence of cyan and yellow on the print. To determine the affected colours with certainty I would recommend doing a test print or nozzle check depending upon how your manufacturer refers to it from your printer.Fixing Streaks and Lines in Scans, Copies, and Faxes - HP Officejet - HP
If however you are experiencing something similar to either of these two issues it is safe to say that one or more colours is partially blocked within your printhead.
Thankfully the majority of printers available have cleaning facilities built into them which are ideal for clearing such blockages or dried patches from printheads.
Whatever your printer calls it I recommend running the cycle times. This cycle forces additional ink into the printhead and will hopefully flush out any dried ink causing print quality issues. The final step will differ depending upon whether the printhead is part of the cartridge is part of your cartridge or your printer.
If you are not sure for your particular printer please use the image below as a guide. The printhead being attached to the cartridge actually works in our favour here as it can easily be removed from the printer. I now recommend taking the relevant cartridge from your printer and running through the physical cleaning procedure mentioned in the second part of the article you can find linked here. If the blockage remains after the physical clean then it is unlikely you will be able to remove it and I can only recommend replacing the cartridge all together.
Sadly the only option that remains is persisting with more cleans, but I recommend leaving a few minutes between cleans to avoid damaging the printhead your of printer. For the sake of completeness you could always try replacing the cartridge but, print quality problems of this nature are unlikely to be caused by any kind of cartridge defect. Some of these printers have replacement printerheads available as consumables, most printers however will require the intervention of an engineer to resolve a blocked or dried printhead.
Hopefully your printer is in warranty and you can get the printhead exchanged free of charge. I hope you have found this article useful. If however there are any points that need clarification or you have further questions please let me know in the comments below. Matthew Stevenson.

How can I tell if my printhead is partially blocked? How do I clear this blockage?

If you Google this problem or search the HP Support Forums, you will find that this problem also exists in other lines of HP printers: e.
I wasn't using the photo tray it was empty and not selected in the program's I was trying to print from.
After less than 2. Note: I have done all of the printer diagnostics several timesboth, via the HP software on my laptop latest version downloaded from HP's website and via the diagnostic tests built into the printer, with my laptop turned Off. The problem still exists, so it is in the printer, not the laptop or the HP's installed software. My guess is that it is bad printer cartridges though, I doubt it or more likely that the long rubber shaft that moves the printer through the printer via gears, is turning a tad too much every time the printhead sweeps across the paper.
My printer is setup to print at Normal quality The problem is obvious in the Print Quality Diagnostics page and the example from a. I have printed a few photos 4"x6" from the Photo Tray, and they appear to be fine.
Another test. I have to select Index Card 4"x6" to be able to print on 4"x6" Photo paper loaded in the Main tray. You would have to load it into the Main paper tray. There are several design flaws here.
But both of these printers went bad for different reasons.
Test prints are shown below. Please read the additional information that I have provided Print Quality Diagnostics Reports. Something is fundamentally wrong with the mechanics or firmware driving the printhead and roller. The best explanation that I received was from an IT printer maintenance guy, who was well aware of the problem.
Any of these could cause the printout to have a consistent blank white line, evenly spaced every 14 mm. HP should be checking their printer or printhead specs for anything relative to a dimension of 14 mm.
HP continues to ignore all of the data that I have presented to them in their forums, only asks me if I am using original HP paper and ink cartridges, won't provide a real test engineer to speak with mevregarding this problem, and tells me that if they choose to do something to address this problem that they would not be informing me of the fix. Not the company they once were, who I have been dealing with since the early s!!!
