Most people around the world are not technologically savvy. They buy a printer and do not know much about printer ink cartridges or about troubleshooting problems that might appear. It is very important that every single printer owner out there reads articles like this one and that research as much information as possible about how to fix problems that appear. I say this because most problems can actually be fixed. You would lose a lot of money if you just buy a new cartridge every single time that something wrong happens.
The dirty printhead can appear due to many different reasons and the fix is actually a lot simpler than what you might think. All that you need to do is use warm tap water. Run the printhead through it for a few minutes. After you are done, use a cloth to dry all the excess water that appears before you put the cartridge back in the printer. The ink that is discharged in the nozzles can be dissolved. Such a fix should be considered whenever cartridges are removed from the printer and are exposed to air for too much time.
Partial Printing And Streaks
When most people see partial character printing and streaks, they think that there is a need to change the cartridge since it is run out of ink. This belief is false. In reality, something like this happens when the electrical contact between cartridges and printers is poor. You will need to basically clean all the contacts inside the printer carriage and on the actual cartridge. The contacts of the cartridges have to be cleaned with lint-free, soft, dry, clean cloth while the other contacts stated should be cleaned by wiping contact pins with a swab that has a cotton-tip and that was dampened in water. All the cotton fibers that might remain should be removed.
This happens because an ink build-up appeared on wiper blades. This is quite common with HP deskjet printers. When this is something that you see, just clean your wiper blades and the problem will most likely be fixed.
Software Display Errors
There are many situations in which you will receive some sort of error message on your computer screen. Most of these problems are solved by looking at the troubleshooting section of the printer's manual that came with your purchase. If you do not have the manual, go online and visit the site of the manufacturer. You will surely find what you are looking for there. As an extra piece of advice, it is a good idea to remove the cartridge and re-install it. This solves most problems that appear.
