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.
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.
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.
Regular washing and waxing helps to remove Black Streaks before they get good and stuck. A good regular wax job helps to prevent Black Streaks in the first place. A good layer of wax will help to minimize the way Black Streaks set into the surface. Waxing creates a physical barrier across the surface.
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.
A cartridge may be running out of ink even if the graphic shows ink remaining (see the note at the start of this section). Lines or streaks always appear in printouts when the cartridges begin to run out of ink. Replace print cartridges that are out of ink or low on ink.
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.
Printing is vital to all businesses so ensuring your laser printer is thoroughly cleaned is crucial as it allows your machine to continue working efficiently. Cleaning a laser printer is easy with the correct equipment, however they are prone to dust and debris.
This is when the laser leaves behind a series of lines that spoil the engraving. The cause is usually an incorrect focus or dirty optics. To fix this, simply clean the lenses and adjust the focus until the lines disappear.
Dirt, dust, or toner accumulated on the rollers or transfer belt can cause smears and smudges on the paper as it goes through the paper. Cleaning your printer, especially its rollers, is one of the possible solutions to fix black marks on paper.
A printer printing lines on the page are normally caused by a blocked, dirty, or damaged print head. Blocked ink cartridge nozzles, or not removing protective seals correctly when you installed a new ink cartridge can also cause missing lines of print.

Samsung ML 2165 Error lights
ANSWER : Hi there, I am having the same problem. Stupidly I bought a second replacement (genuine Samsung) cartridge thinking it may have been a faulty cartridge as sometimes it deemed to work after a bit of messing around. SO NOW I HAVE ONE NEARLY NEW AND ONE COMPLETELY NEW ; ABSOLUTELY NO USE TO ME – unless I can get the printer to accept them.
