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.
Printer Faults – Faded One Side of a Print. Fading at a margin generally suggests: an imbalance of the toner, all of it is unshiftably at one side of a cartridge. The toner agitators or stirrers should move the problem but don`t invariably succeed.
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.
Faint, streaky or spotty prints are all common signs of a clog but a simple cleaning can usually get your HP ink cartridges working again. Printheads clog due to infrequent cartridge use. If you regularly go a few weeks without printing, your cartridges will eventually dry out and need to be replaced.
The problem may be due to a simple issue like printer paper quality or ink/toner cartridge wear, or it could be a more serious problem that requires professional repair.
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 the problem is isolated to one color, set the printer to Disable Cartridge Check and swap cartridges. If the problem disappears, the old cartridge was obviously bad. If the problem persists, something associated with the cartridge is to blame: its high voltage contact, high voltage circuit, or laser scanner.
Streaks, smears and stripes on your printout are all signs of a bad cartridge, as is a lack of a particular color or a color appearing very faint. Sometimes the printer refuses to print if a cartridge is faulty.
The replacement toner is already used in another printer

A used toner cartridge will have the reset lever. But because it has been used in another printer already, its reset lever will not be in the right position to activate the printer to reset the toner level. Please use a new, unused replacement toner cartridge.

Air exposure causes your prints to fade by a process called oxidation and, short of sorting your photos in a perfect vacuum, you can`t stop it. Assuming you don`t have access to a perfect vacuum, your photographs resistance to air will depend on the type of ink it uses.
In the [Advanced Settings] dialog box, select [List of Settings] [Toner Density] [Adjust] → click [Details]. Adjust the density for each color → click [OK].
You can visually inspect the remaining cartridge levels on your printer. If they are full but you still cannot print properly, check the cartridge`s expiry date. Expired ink cartridges often dry up which causes problems in the print results.
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.
Dirty printheads

Dirty nozzles, leftover toner, debris, or dust can interfere with your printer and cause ghosting. Run the printer`s built-in cleaning function multiple times, and print a test page between each. Repeat this process until the ghosting issue disappears.

A ghost printer is a deleted printer that keeps appearing and reappearing even though you`ve tried to delete it and then done a server reboot.
Binocular double vision is the result of misaligned eyes. This can cause the images you see to be off, resulting in ghost images.
A ghost image occurs when the object or anatomic structure is located between the X-ray source and the center of rotation, and has a density that is sufficient to attenuate the X-ray beams.
Ghost imaging, often called cloning, is a software-driven data backup process that copies the contents of a computer hard disk in a single compressed file or set of files, referred to as an image.
Clean the printheads: Sometimes the issue why you are unable to print in color is because our printheads are clogged with ink. Clean the printheads and then print a document to check if color printing works. Some printers also have in-built programs that can clean themselves so remember to check for that.
Color laser printers use colored toner (dry ink), typically cyan, magenta, yellow, and black (CMYK). While monochrome printers only use one laser scanner assembly, color printers often have two or more, often one for each of the four colors.
The most obvious sign of low toner cartridge is poor print quality. Streaking, lines or missed prints are all possible signs that cartridge replacement is imminent. If you have tried rocking the toner cartridge and are still getting poor prints, it is likely time to replace your cartridge.
When an indicator shows low ink levels, consider having a replacement ink cartridge available to avoid possible printing delays. You do not need to replace ink cartridges until you are prompted to. In general, low ink levels should not impact print quality.
Printing in “draft” or “economy mode” uses less ink and is a great way to preserve your cartridge life and prolong cartridge replacement. If you are printing out a document like an email where print quality isn`t an important factor, switch your printer to this setting!
If the cause of your problem is a wired or Bluetooth keyboard, then the simplest solution is to replace this keyboard with one that is specifically designed to be anti-ghosting. These keyboards get around the problems that cause ghosting in different ways.

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.

HP Color Laserjet blank pages – only jetdirect page
ANSWER : What about the engine test? To do that, drop down the front tray. Feel around on the left side at the top and you’ll feel a little plastic dongle. If you lift up on that it will initiate an engine test page. That will be a page containing lines of each color.
