Here are the most common causes of a printer printing faded text or images: Low ink or toner levels. Toner sticking to the fuser roller or problems with the transfer roller. Low ink or toner density settings.
The most common reason for getting faded prints is having empty or defective toner cartridges. It is unbelievably frequent that people forget to replace their empty toner cartridges and struggle to figure out why their printers print faintly. Another common reason is that people use defective cartridges.
You do not need to replace ink cartridges until you are prompted to. In general, low ink levels should not impact print quality. Your printer stops and displays a message when ink levels get too low. However, the printer might still perform a limited amount of printing in `backup mode` at low ink levels.
In the [Advanced Settings] dialog box, select [List of Settings] [Toner Density] [Adjust] → click [Details]. Adjust the density for each color → click [OK].
Printers may produce poor quality printing if they are exposed to too much heat. Don`t place your printers in a high-temperature area or near other devices that produce excess heat. In addition, keep them away from windows, where heat and humidity can be high.
Issues in your printer`s ink or toner cartridges as well as an empty paper tray can cause your printer to delay your prints. Make sure that your cartridges are not running out of ink and the paper tray is not empty. You can follow HP`s guide on how to check ink or toner levels here.
If your prints are faded or blotchy, it may be time to replace your ink cartridges. When ink levels are running low, it can dry out and clog the ink nozzle. This means your printer will try and produce more ink than it usually would, which could cause your printer to break down.
The quick answer is: Yes, you can (if you own a printer model that allows it) — but you shouldn`t keep printing with an empty cartridge for too long. Why? Because running on an empty cartridge for too long can cause your printhead to overheat resulting in irreversible printer damage.
Ink cartridges can dry out over time. If they are sitting in your machine for an extended period, they will eventually dry up and become unusable. The simplest way to combat this problem is by printing more frequently or running regular cleans and ink tests to ensure the nozzles remain clean.
Print density is the measurement of light reflected off of the substrate, or how dark the print appears after each press strike. When looking at the definition of print density it is easy to see how the materials that come in direct contact with the printing surface play a crucial role in print density quality.
How do you know which developer to use with the toner? 10 volume will allow the toner to deposit more color, 20 volume will deposit less. Once you decide which toner shade and developer you will use, measure using a hair color measuring cup and mix 1 oz.
Most toners can be applied directly to the face with either fingers or a saturated cotton round. One to two pumps is usually enough to cover the entire area. Some toners also come in spray bottles and can be misted over the face.
Achieving good print quality can depend on several factors, including the printer`s maximum resolution, the quality of the original files being printed, and the number of dots the printer can produce. Other components, such as the quality of the toner or ink, can also impact print quality.
If you`re looking for high print quality, you need to make sure your images have a high DPI or PPI. DPI stands for dots per inch, and PPI stands for pixels per inch. The higher the DPI or PPI, the more detail will be visible in your printed image.
A common cause of faded, faint printouts from your inkjet printer is dried ink particles causing a blockage in your printer. The printheads on an ink cartridge can be become blocked if the printer is not used for a period of time, so it is recommended to print a few pages each month to maintain the print quality.

Print file sent but no printing occurs
ANSWER : Been working on these since they first were released. Never seen a problem like yours. If it happens again, try doing an engine test, as it bypasses the formatter board. The engine test is located at the right side of the manual tray opening. Look for a hole in the side wall. Stick something like a paper clip into it to actuate the test button. It will then print a lined test page. If it does that, then it points to the formatter board as the cause of your problem.
