How to Identify and Fix Common Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced technical support :

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.
What`s happening is that the drum or rollers could have a fingerprint or dirt that is smudging the toner on the page as it passes through to the fuser. It is normally caused by the rollers. If the marks are always in different places, then it`s most likely to be the drum.
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.
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.
When your printer leaves black lines, the lines indicate that there are excess toner powders on the rollers or transfer belt within the printer. As the paper is moved along by the rollers and transfer belt, any excess powder left on them can result in lines being left on the paper.
The best way to prevent smearing is to make sure you give the ink time to dry before picking up the copy or copies. It doesn`t take long, maybe 10-15 seconds. If that doesn`t work, try changing your printer settings for a lower quality print job. You generally have a choice, Best, Normal or Draft.
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.
Check the toner level

The first step for light and faded prints is to check that your toner cartridge is not running low or empty. If your laser printer has a built-in LCD screen, you should be able to view the toner levels on screen or via a printed test page accessed in the settings menu.

Sponge rubbing alcohol into the stain.

Pour rubbing alcohol onto another paper towel and use it to sponge around and directly on the stain. If the towel underneath the stain becomes too stained, remove and replace it with a clean one and continue to sponge until no more ink is being removed from the garment.

(smʌdʒ ) verb. If you smudge a substance such as ink, paint, or make-up that has been put on a surface, you make it less neat by touching or rubbing it. […]
To smear something is to smudge or blur it. You might literally smear your pen-and-ink drawing, or figuratively have your reputation smeared by getting caught in a lie.
Streaks and unwanted lines could mean that the printer heads are out of alignment. There`s an alignment tool in the printer`s control panel. If that`s not the issue then the printer is dirty. Printer ink stripes may appear along the edges of the paper, which means there`s ink on the rollers and other parts.
If your laser printer is causing horizontal black lines you either have a problem with the optics or the drum. Cleaning the optics and replacing the drum should fix the problem in most cases.
Streaks and unwanted lines could mean that the printer heads are out of alignment. There`s an alignment tool in the printer`s control panel. If that`s not the issue then the printer is dirty. Printer ink stripes may appear along the edges of the paper, which means there`s ink on the rollers and other parts.
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.
For cleaning, HP recommends using HP Equipment Cleaning Wipes, but you can use an HP-approved lint-free wipe and deionized or distilled water. Note: If dark spots appear on back side of prints, clean drum screen. Note: If minilab prints more than 2000 prints each day, clean drum screen up to twice daily.

Smudges down right side of paper
ANSWER : That doesn’t make any sense. Sheets that feed from the manual feed or the cassette tray both converge before the toner cartridge. That would mean that the smudges would somehow be put on the paper as it was feeding upwards from the tray. There is nothing in the printer that could account for that happening.
