Printer is printing with black bars what to do?
often than not, inkjet printer streaks because of the ink or because of the print head. But sometimes the printer prints stripes due to mechanical damage, failure of some important elements, for example:. the encoder ribbon is not read.
The dark bars are equidistant from each other
It is possible that the toner tank is overfilled. You should check it and the correct refill of the cartridge as a whole. If this does not help, the contact between the magnetic roller and the image drum is most likely broken. This happens because of wear and tear on the parts in the cartridge.
Printer cleaning and software replacement
If the cartridges are installed correctly, you are using the recommended ink, the CISS is installed correctly, and the paper is of suitable quality, you should run a head cleaning and then let the printer stand for about an hour. If this approach is unsuccessful, you should run a deep cleaning and also wait after that.
Replacing and reinstalling the software can make a difference, but this cause is very rarely seen with incorrect color of the printed image. In the case of software failures, the printer will usually either not start or will give you a print error, but will not distort the color.
If the simplest troubleshooting measures don’t yield the desired results, you shouldn’t try to solve the problem by mechanically tampering with the equipment
This will not produce the desired results, but it is possible to completely disable the technique through negligence. Therefore, a much simpler and safer method would be to ask for help from professionals

[solved] How to print without black ink?
Okay, I think this is going to be my last printer tutorial, and the only reason I’m doing this is because yesterday Allan had a situation where his printer ran out of black ink. and he still needed an A3 poster. Kyle Jenner (just kidding, man, I know it was #businessimportantthings).
So, with this story in mind, I wanted to cover one last article, but before we do, let’s check out what else I’ve written in the last few weeks, and maybe one of them can help you further solve your problem, here are the big six : Epson printer doesn’t recognize ink cartridge, How to extend cartridge life, How to reset Epson cartridges?, Memo on HP printer error codes, My HP printer isn’t working, The difference between Canon PGI and Canon CLI inks.
If your problem is not related to the problems described above, let’s try to figure it out another way, because today we’re going to talk about. How to print without black ink.
You shouldn’t print with empty cartridges. Here’s why
I know how it is, don’t tell me, those inks and toner are out of control. It would currently cost you at least 100 to refill your entire machine, so I’m on your side, trust me, but there’s actually a good reason why some companies, like HP, won’t let you print with an empty cartridge, even if it’s just one empty unit.
Basically, your machine consists of several parts, one of which is a little more complicated than the rest, and that is the print head of your device along with its nozzles (I’m going to share an image below so you get the gist ). Once you assign a print job to the device, it will start sucking up ink from all the cartridges, regardless of the color of the print, just to maintain the print head and keep the overall fluid flow inside the device. For example, we all grew up on Capri Sun juices, right? Well, imagine you’ve been sucking on a box through a straw for a while, and at some point you find that you have an empty juice box, and instead of juice, you have a lot of air in your mouth with a few splashes here and there. well, a strange example, but the same thing happens to the printhead when it sucks in an empty cartridge, air gets into it, and this damages it in some cases.
Not only that, depending on the printer, the ink is used for other purposes, not just printing. Thermal inkjet printers also use the ink in the cartridges to cool the device, which in turn keeps the thermal components running. In some piezoelectric vacuum systems, such as Epson printers, air is the worst enemy of nozzles, which contain a small crystal that only works properly when the ink flows through the nozzle. If air is coming in, you have a problem that is not easy to solve. Even if you decide to replace the cartridge, air will still remain and cause print quality problems.
So, to maintain natural ink flow, print jobs and cleaning cycles, you should always have at least some ink in all cartridges. If you see that you are slowly running out of black ink, try implementing some of the solutions below when you still have black ink left, and use other colors as long as the device can support the printhead and cleaning cycles with the remaining ink.
The cartridge is really empty and how does the printer know that?
The funny thing about computers is that sometimes we think there’s really sophisticated technology behind them, but mostly it’s just zeros and ones.An example with printers: when you buy a cartridge, that cartridge comes with a chip on the back. The chip is read by the printer and signals the printer, “Hey, look, I’m new, and here’s a certain number of pages I can print, which, for this article, is 300 pages.”. And now the process goes on. Like this:
- A black ink cartridge (or any cartridge) has a chip
- The chip signals the printer that it has ink for “about 300 pages.”.
- You connect the printer to your computer and install the drivers/ its software.
- The computer sends print jobs to the printer
- Printer software calculates the number of pages of a certain color
- The printer software subtracts the number of “pages printed” from the number of “pages available”.
- When the software determines that you have printed 150 pages of black text, it tells you that there is 50% ink left in the cartridge.
- Finally, as you probably guessed, after the software calculates between 290 and 299 printed pages, it will tell you that there is no ink, but.
- There is ink left over for the few remaining pages that are used for the printhead and normal printer cycles and are not available for actual printing.
To make the whole story even more interesting, HP, which I constantly dismiss because of their business practices, deliberately programmed the chips so that they would offer a certain number of available print jobs, regardless of the amount of ink in them. So you will get a message “: ink cartridge empty, error “, but your cartridge will still be able to print about 50 pages of written content, just because they have programmed the chips in this way. At one time it was a huge scandal that caused the company to lose millions.
So. It’s simple, we just kill the chip that signals the number of pages, right?
Well, not really. There are tens or hundreds of thousands of printer models, and there are thousands of different chips, designs, and cartridge sizes, so it is impossible to get a “universal method” to work with all of them, but there are ways to. I explained how to reset Epson ink cartridges in this article here: How to Reset Epson Ink Cartridges ?, But other manufacturers can make it pretty complicated.
For example, there are many videos on how to mask the chip so the printer can’t read it, one example is Andrew, who showed how to remove the Brother cartridge and mask it so the printer can read it again, you can check the pictures below or watch the video at this link.
Troubleshooting a printer that is printing all black pages
The problem with printing full black pages can occur to any user of a printer or all-in-one printer, but it appears rather rarely. Nevertheless, today we would like to talk about all known causes of this problem and propose some solutions that can be done manually without a call to a service center.
Troubleshooting printer malfunctions with all-black page printing
The problem mentioned above is almost always caused by hardware failures, so not every user will be able to fix it on their own. Below we will tell you exactly what components or other factors cause such a difficulty.
Light on the image drum
The image drum is an element of the cartridge that receives a signal from the computer with information about further printing. Feature of this element consists in sensitivity not only to sunlight, but also to light as a whole, that’s why the removal and repair of the image drum is made under the dim light in a special room.
Sometimes light falls on the drum, which is associated with improper operation of the printer or cartridge replacement, as a result of which there are shadows on it and the part fails. An obvious symptom of malfunction is black printing.
It can be solved by replacing the element or sometimes the sensitive coating restores itself, but it requires a certain amount of time.
Problems with contacts
The printer receives and processes information through an internal control panel with its own internal memory, ROM and processor. It can happen that over time, the contacts on the device begin to loosen or oxidize, which causes various print failures, including the appearance of black sheets. Then you can try to disassemble the device yourself, check the contacts and clean them with an eraser. Read more about this in our separate article at the following link. There is a detailed description of the complete disassembly of the equipment, so all that remains is to deal with the wires.
Using the wrong type of paper
Sometimes unknowingly users put into a regular inkjet or laser printer a fax paper that is not suitable for printing on such devices, and it instantly turns black because of the ink and temperatures. We advise you to choose your sheets carefully, avoiding this non-standard format.
No corotron or charge roller
In laser printers, one part of the cartridge is the short cartridge or the charge roller. These elements have the same function, but a different structure. The corotron is a short stretched wire, and the charge roller is a relatively thick metal rod that takes on AC and DC current when the equipment is running. When repairing a cartridge or replacing ink, the parts mentioned are sometimes taken out. If you forget to reassemble them, printing will not work correctly. Therefore, if you have recently changed ink or received your printer from a repair, it is advisable to check the presence of the corotron or the charge roller.
High voltage unit failure
The high voltage unit is one of the main parts of a printer and all-in-one printer and is responsible for ensuring that the correct amount of electricity is supplied. If you have inserted a cartridge into another printer and printing is normal, it is this component that should be diagnosed. You can not do it yourself, so it is better to contact a service center for the analysis and further repair of the component.
Poor quality cartridge
Some cartridges are leaky, which causes various problems when using them. Usually the first sheets print fine, but eventually some of the toner or ink spills over, resulting in smudges on the paper or getting completely black sheets. There is only one way out in such a situation. cartridge replacement followed by a complete cleaning of the printer internals if any ink has seeped into the components and the take-up roller. Figure it out will help our individual articles, which you can find at the following links.

Above you have been introduced to the most common causes of black sheet printing. If none of these helped you to cope with the problem, feel free to contact the service center for expert help, perhaps the fault lies in a very unobvious place. We’re glad we could help you with your problem. Describe what you have not been able to do.Our specialists will try to answer as quickly as possible.
What to do if your printer prints all-black sheets
The job of the photovalve is to use the printer’s lasers to put an invisible image on it, completely replicating the picture sent from your computer to print. The image drum is very susceptible to excessive light. In those places where under the influence of light the charge will change to the opposite of the charge of the toner, the dye will stick just like to the areas with the invisible pattern. As a result, the finished document will show black spots in the “highlighted” areas.
It is possible to illuminate the image drum if you disassemble or even replace the cartridge in a well-lit room.
All actions with it must be performed in complete darkness, after refilling the image drum must be quickly wrapped in paper, otherwise you will have to change the shaft for a new one.
Wrong type of paper
If the printer prints in black, the cause may be in the wrong choice of paper. You should be suspicious of paper if you bought it recently and haven’t used it before. Sometimes unsuitable paper leads to fires inside the printer. This is especially true for fax paper in laser printers, which turns black at high temperatures.
After refilling, small black print defects may appear immediately, which is normal.
Just print a few more sheets to get rid of them. Black marks appear if toner gets on various parts during refueling and the refueler is too lazy to remove the powder.
If you have already printed more than one document, and the printer is still printing black sheets, it may indicate a cartridge leak. This can be fixed by taking it apart, reassembling it, and installing it properly.
Causes of black sheet printing
Here are the most common causes and solutions to problems with a printer that prints black.
- Unsuitable toner. This is probably the most common situation. You have not found a suitable original toner or you have decided to save money and bought inexpensive toner from a different manufacturer than your printer. However, there is a reason why manufacturers of printing equipment, especially all-in-one printers and printers, do not recommend the use of non-genuine parts and supplies. For obvious reasons, the composition of toner from each manufacturer differs in chemical composition, physical characteristics, melting temperature and other parameters, optimally adapted to the brand of one or another printer. Whether it’s Xerox, Canon, Panasonic, Epson or another manufacturer. What to do: Buy new original toner. Make it a rule not to save on consumables and buy only original cartridges, toners and parts. In the end, you will avoid a lot of problems with buying the wrong toner and save money on recharging/repairing equipment.
- Leaky cartridge. Also a common problem with sloppy refills. If the cartridge can not be repaired, you can always buy a new cartridge for your printer in the online store V-Print.UA in Kiev and Ukraine. Some of the toner powder may have simply fallen out of the hopper because the cover is hermetically sealed or you have not inserted the plug. What to do: remove the cartridge from the printer body, screw the cap tight, or insert the plug (depending on which model of printer you have). Gently wipe off the spilled toner with a soft, dry cloth. Insert the cartridge in place.
- Lighted image drum. If you have done any manipulation in the printer enclosure recently, you may have “lit” the Xerox image drum. This part is sensitive to sunlight, so you should avoid touching the photo roll and exposing it to UV radiation when replacing the cartridge/refilling the toner. The top layer of the image drum may have failed, so the printer prints a black sheet if it is lit or depleted. Solution: the part is not repairable, so you will have to buy a new image drum for your printer model from a specialized store.
- Contacts on the cartridge. If the cartridge is inserted carelessly the contacts can be damaged. Also this part wears over time and the printer prints black. What to do: Remove the cartridge from the body of the printing equipment contacts are often on the left side. The lower contact leads to the magnetic shaft, to the charge roller. The top one, respectively, and that’s where the problem is most common. Both contacts are spring loaded and can be felt to determine if the contact is stuck or in service. If the contact is stuck. Move it carefully into position with your hands or a screwdriver. Insert a Canon cartridge into the printer and try to print.
- Primary charge shaft grease has dried out. Inside the cartridges has a special detail. PCR or primary charge roller. Over time, the shaft lubricant simply dries out and the printer prints a gray or black background. Often, this situation occurs after refilling the cartridges. What to do: Apply a special lubricant to the PCR. You can buy it at a specialized store along with the toner.
- Electronics problems. Like any other machinery, printers can malfunction and print black or gray backgrounds due to malfunctions in the electronics. What to do: if you have no skills you are unlikely to be able to repair the electronic stuffing of your printer at home. We recommend to apply to the service center, where they will quickly identify and repair the problem.
