How to Identify and Fix Common printer Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced technical support :

If ink is not coming out when you perform printing for the first time, it is possible that ink is not flowing into the printer properly. Make sure each ink tank is filled with ink to its upper limit and perform ink flush. If the problem is not resolved yet, the print head may be damaged.
If the ink level is sufficient, but the printer still does not print black ink, you may need to run a cleaning cycle. A cleaning cycle is a process that cleans the printer heads and removes any clogged or dried ink.
Check if the ink tank for the problem color is empty. If the ink tank is not empty, perform print head cleaning and try printing the nozzle check pattern again. If problem is not resolved after performing print head cleaning twice: Perform print head deep cleaning.
Black-and-white printing may use ink other than black ink depending on the type of printing paper or the settings of the printer driver. So, color ink is consumed even when printing in black-and-white.
Several factors may cause the product to print blank pages, such as print settings, low ink, or the product itself. Check the following: Make sure the product is placed on a flat, stable surface that extends beyond the base in all directions. The product won`t operate properly if it`s tilted or at an angle.
If your PC or the LCD screen on your printer is telling you that your ink cartridges are full but no ink is passing through to the paper, then it`s most likely that you are dealing with a clogged printhead. Blurry documents and images that appear faded are also signs that it`s time to remove the excess ink.
When color ink is expended and black ink still remains, you can continue printing for a short time using only black ink. However, you should replace the expended ink cartridge(s) as soon as possible. See the following section to continue printing temporarily with black ink.
Just above the circuit board on most printer cartridges, you`ll find a small button. You`ve seen these tiny buttons before on cell phones, phone chargers, etc. This is your reset button, and the only way to get in there is either with a paper clip or the tip of a pen (which will leave a tiny ink smudge on the button).
With the printer powered on, select Setup . Select Device settings . Scroll to the bottom of the menu list and select Reset settings.
If your printer is spitting out pages full of strange characters, symbols, or strange formatting, your inkjet printer drivers may be outdated, incompatible with your operating system or corrupt. Drivers are important to the proper function of your inkjet printer and it is best to check for updates regularly.
