If you have printed a document or photo and the print is too light, patchy or faded, a common cause is the toner cartridge nearing the end of its life. However, there can be other reasons behind the deterioration in quality such as the toner density, humidity and the type of paper being used.
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.
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.
Laser printers have a reputation for excelling with text-based documents and high-volume printing, compared with inkjet printers which are typically thought of as better with images and smaller batches. Ink can also smudge and may fade over time, while you won`t have this problem with toner from a laser printer.
Unfortunately, there is no way to restore faded ink to its original state. Some chemicals are advertised to darken original inks, but they are often damaging to paper and conservators do not recommend them.
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.
Open a document to print on the computer, and display the setting screen of the printer driver from the print menu in the application. Click [Print Quality:Standard] of the [Detailed Settings] tab. Select [Advanced Settings] in “Adjust Image Quality/Color”, and then click [Details…].
Smears and smudges on the paper can be caused by dirt, dust, or toner accumulated on the rollers or transfer belt as it passes through the paper. Cleaning your printer, particularly the rollers, is one of the options for removing black markings from paper.
Partial prints are a common issue with printers and there are several main reasons it can occur: Problem with the print spooler (on Windows PCs) Overload of the GPU on later model Macs. Dodgy USB cord.
Dust, air, smoke, and chemicals can settle on the surface of an image, and the emulsion will change. This causes the photo to break down and fade. Photo Damage: Silvering, mold, and water damage can all cause a photo to fade over time.
Laser Toners Resist Fading When Exposed to Strong Light
Outdoor signs can fade from exposure to strong sunlight. Indoor signs can also fade when exposed to strong artificial light. Bright light can cause dye-based ink applied by some inkjet printers to fade in a short amount of time.
Receipts are printed on thermal papers, which are chemically coated with heat-sensitive dyes that display text and images when exposed to heat. Thermal papers are susceptible to heat, and extended exposure to heat and other harsh environmental elements lead to gradual fading.
Place a non-fluffy, thin towel on top of the receipt and place a heated iron on top. The heat from the iron will help the ink show up better and become legible again. This tactic is good for receipt paper that has faded ink but is otherwise in good condition. Run the receipt through a laminate pouch in a laminator.
If a fuser unit is not heating the toner powder correctly, ghost images can appear when printing. You can check to see if the fuser unit or drum unit is causing the ghosting by having a look at the ghosted images.
If you`ve had your printer for a while and your print is still not bright or vibrant, it`s probably your time, temperature, or pressure. You need all three in order to sublimate on something – you need the correct time, the correct temperature, and the correct pressure.
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.

Laserjet 4250 print quality issue (see image)
ANSWER : It looks like a fuser problem. One way to prove it is with the half-stop test. Put a sheet in the drop down manual feed tray. Send a print job and watch the paper. When the end of it is about to enter the printer, open the lid and take out the toner cartridge. Look at the printed image. If it looks OK, then it is a fuser problem. If not, then it is a toner cartridge issue since it hasn’t gone through the fuser.

HP Laserjet 1320tn printing grey instead of black
ANSWER : Try this test. Put a page into the manual feeder and do that same test. When the end of the page is just about to enter the printer, open the lid. Take out the toner cartridge and pull back the shutter. Look at the image and see if it is black. The explanation is that there is high voltage going to both the toner cartridge and the charge transfer roller below it. If the image on the drum is black, then the fault is at the transfer roller not getting enough high voltage. The transfer roller pulls the image off of the drum and down onto the paper. It would not be a laser scanner problem as any issue with it would not result in an overall gray image, but combination of gray and black. It will probably turn out to be a bad HV power supply, which will need replacement. I’ve never seen this particular problem on this model.

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.

when printing front and back, the front will print well but the back will fade
ANSWER : It happens because second side voltage is much higher and the board breaks. Are you getting this issue in auto duplex only, or same error you are getting when you print second side manually?

My 2550n Color LaserJet does not want to print in color
ANSWER : That model had issues with the carousel solenoid sticking. That might explain why it works after you let it sit for 10 minutes. The solenoid gets hotter with use which causes the deteriorated foam on it to become sticky and hold down the release plate instead of letting it go. This allows the carousel to spin when it is supposed to stop for each color. The solenoid is located on the right side of the printer. If you open the lid, it is just behind the opening at the top right. You need to remove the top of the printer and scrape off the goo on top of the solenoid body. I put a piece of thin sticky backed felt to replace it. Other people use electrical tape.

Black line printing in the middle of the page from top to bottom
ANSWER : Take out the toner cartridge and look at the drum. If you see the line, replace the cartridge. If you don’t, then you need to replace the fuser assembly.

Prints blank pages, won't print from computer
ANSWER : Don’t know why you replaced the fuser, but assuming you had print before, then it must have been something you did during the procedure. Only thing I can suggest is to recheck your work. Just because you reinstalled a connector doesn’t mean that it is seated firmly enough to work. Any flat ribbon connectors that you removed and reinstalled, check to see that the contacts are all flat and not peeled back.
