What causes ghosting? The most likely culprit is either the imaging drum unit or the fuser unit, however humidity and the incorrect paper type can all play a role in ghosting. Ghosting is often caused by a malfunctioning imaging drum unit.
Ghost prints happen when the drum or fuser unit within your printer become faulty. Because a fault with this element won`t heat the particles of the toner to a high enough temperature, the marks being made on the paper are much lighter in colour and appear more faded than typical documents.
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.

Usually a quick paper setting adjustment will clear up a ghosting issue right away. Run a cleaning – Most printers have a cleaning function built into the machine. Run this a couple of times to attempt to clear up the printing issue. Inspect the drum – Sometimes excess toner powder can stick to the drum.
To prevent ghosting, it is crucial to be efficient with the speed of the print head and the material. This means slowing down the print head in time and gradually, and printing less material before changing direction. For example, before a sharp turn.
Binocular diplopia occurs when ghost images appear when you have both eyes open. Since it affects both eyes, this condition results in two sets of ghost images overlapping the primary image. In this case, the only way to remove the ghost images from your field of vision is by closing or covering one or both eyes.
Ghost images, like those created by cataracts, usually are seen by only one eye. Ghost images can occur after corneal surgery, such as LASIK, PRK or a corneal transplant. Most of these problems disappear when the problem is resolved, like after cataract surgery or when the refractive surgery heals.
“ While ghost images of some anatomic structures cannot be avoided, most ghost images can be excluded or reduced.”
Dots are typically caused by foreign material inside the machine (for example paper dust, glue from labels or envelopes, paper clips, staples) sticking to or damaging the surface of the drum. Toner builds up on or sticks to these areas on the drum and creates black dots on the printed pages.
Ghost images are light images of pages that were previously printed that are appearing on the currently printed page. This is usually caused by the erasure lamp or cleaning blade. The cleaning blade is part of the toner cartridge and is easier to replace than the erasure lamp. Try replacing it first.
Wipe clean the cartridge carriage where the cartridge connects to remove any dried ink (make sure the printer is off and unplugged). If the printhead is built into the printer, clean where the ink comes out with a damp cloth. Re-install cartridges and run a print head cleaning process.
We know that rather than the migration of any process ink or varnish components through the substrate, ghosting occurs as a result of the oxidation by-products of the first pass sheet`s printed ink film, either altering the surface energy (surface tension) of the substrate – which then impacts on the transfer of ink …
`Ghost mode` is what Snapchat call privacy. Ghost mode will let you keep you location private but you will still be able to search around for your Snapchat friend`s location – if they decide to keep their location public.
When you enable Ghost Mode, your location won`t be visible to anyone else on the Map! You can turn Ghost Mode on and off, or set a timer if you only want to be on the down low for a little while.
People ghost for a variety of reasons. Relationship experts and psychologists agree that people who ghost are avoiding an uncomfortable situation. This evasion, while perceived as a lack of regard, is often because they feel it`s the best way to handle their own distress or inability to clearly communicate.
Toner cartridge issue: The most common cause of black shadow printing is a faulty or damaged toner cartridge. If the cartridge is not seated properly, or if it`s damaged or old, it may produce uneven or incomplete prints. Drum unit issue: The drum unit is responsible for transferring the toner to the paper.
Streaking is usually caused by a worn out drum unit or spent toner cartridge. Drum units are a consumable and only need to be replaced after the use of 3 or 4 toners. Not all printers use a separate toner and drum unit.
This can be caused by debris or contamination on the drum, the transfer corotron, the device not positioned properly on a solid flat, level surface, or by using old or damp paper.

Print Quality Issue (Streaks and Ghosting)
ANSWER : Streaks are mostly caused by internal drum wiper blades that clean left over toner off the drum to prepare it for a new image. Ghosting is caused by a leftover image on the drum. The 6 inches that you mention would be the circumference of the part that is causing it. Fusers will never cause either problem.

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.

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.
