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 printer is either low in toner, the density is set too low, or the Economode may be turned on. Remove the toner cartridge and shake it. This will redistribute the toner and often will temporarily solve the problem. However, this usually indicates it is time to install a new cartridge.
Like a photocopier, laser printers read the electronic data from your computer and beam this information onto a drum inside the printer, which builds up a pattern of static electricity. This attracts a dry powder called toner onto the paper which is then fused using heated rollers.
Check that the correct paper is properly loaded into the printer and is not jammed. Replacing damaged cables, plugging in loose or disconnected cables, and fixing paper jams as necessary may resolve the issue.
You need to ensure your HP printer has enough paper, ink, or toner, and it is not stuck on paper jam. Also, check the status of your printer cartridge and try replacing it with a new one if it is not good enough. In some cases, your HP printer stops printing after you replace its parts.
Common causes include dust and grime, worn rollers, or inappropriately weighted paper. Prevent paper jams by regularly cleaning your printer and replacing parts as needed. Check the weight of paper that your printer is rated for as well. The printed product is faded.
Reasons why your HP printer has ink but won`t print
This may seem obvious, but it sometimes happens: first make sure your paper tray has paper in it. Misalignment, clogged printheads, faulty data communication or insufficient ink levels can also be sources of the problem.
Your printer should have been packaged with a USB cable regardless of whether it is a wireless or wired printer. Plug the cable into your printer and your computer`s USB port. The direct linking should trigger your computer to recognize the printer and start up the software needed to complete the installation.
Laser printers, unlike inkjet printers, do not use ink cartridges. Instead laser printers use toner cartridges, so be sure to purchase accordingly depending on your printer. Toner is a fine dye power that is melted onto the paper.

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.

I would suspect the fixing film has wear. You can prove the theory by doing a half-stop test. This stops the print before it enters the fixing film assembly. Load paper in the drop down MF tray in the front. Send a print job and when the tail end starts to enter, open the cartridge lid on top to stop it. Then remove the toner cartridge and look at the paper. If you see the marks, it is from the toner cartridge. If you don’t, it would be coming from the fixing film since the paper hasn’t entered it.
