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.
Samsung will spin off the Printing Business Unit into a separate company as of November 1, 2017 and sell a 100 percent stake of the newly created company and overseas assets related to the business to HP. Under the agreement, Samsung will source printers from HP and continue to market in Korea under the Samsung brand.
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.
The drum unit may need replacing if you notice the printer producing blurry, low-quality images. Black or colored toner spots on printouts also indicates a failing drum unit. In some cases, horizontal lines may develop across the printout every time the paper passes the failing part of the drum.
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.
Great at producing photo quality prints and image-heavy documents, as inkjet printers do a better job of blending and producing vibrant colors than laser printers. The price of an inkjet printer is less than most laser printers. No warm-up time needed before printing.
Printer Business. Palo Alto, Calif., November 1, 2017— HP Inc. (NYSE: HPQ), the world leader in printing, today announced the completion of its acquisition of Samsung Electronics Co., Ltd.`s printer business in a deal valued at $1.05 billion.
If you notice white or dark lines in your prints (also called banding), try these solutions before you reprint: Run a nozzle check to see if any of the print head nozzles are clogged. Then clean the print head, if necessary. Make sure the paper type setting matches the type of paper you loaded.
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.
All laser printers require a toner cartridge and a drum unit to produce a print. However, some printers only need you to replace the toner cartridge, and others require that you regularly replace both the toner cartridge and the drum unit. Most printers use toner cartridges with the drum unit built into the cartridge.
You`ll know the drum is dirty if you notice that the print quality has become blurry and features blank spots or oddly-colored spots despite having full toner cartridges. Horizontal lines across the printout when the paper passes over a dirty area are another sign that it`s time for some maintenance.
While you still should keep your distance from that coughing coworker, you also should avoid sitting near the printer, as its toner could be toxic to your health.
They`re significantly more reliable, too, based on our exclusive surveys of CR members. Laser printers don`t have ink nozzles, which means clogs aren`t a problem, so unlike inkjets, which use ink just to keep those nozzles clean, laser printers don`t waste toner on maintenance.
Thermal printing is almost always faster than laser printing. The process is much simpler for thermal printing, and while print times can vary widely between models, you should still see 5-6x faster speeds with thermal printers. Also, laser printers require a short warm-up time before they can start.
If you want to print a lot of text, a laser printer might be better. If you want clear, high-quality images, go with an inkjet. Overall, you should consider your space and money constraints, as well as other aspects like noise, whether you`ll want to use photo paper, and how much time it takes to print a job.
Laser toner is made up of a dry, ultrafine powder, which has a positive electrical charge so that it sticks to the printer`s drum. Laser toner also contains a compound called carbon black, which the International Agency for Research on Cancer (IARC) calls a Class 2B carcinogen [Source: IARC].
Laser printers don`t suffer from the same performance issue as inkjet printers when left idle for significant periods of time. Inkjet printers often get clogged up with dried out ink when not in regular use. Keeping them maintained requires careful cleaning.

The Samsung Colour Laser Printers range from Printerland is perfectly suited to the demands of both professional and amateur print jobs in the home.

Streaks on your print jobs are a result of your copier glass being dirty. “Dirt” is created by fingerprints, dust, and other forms collected through usage. Often this will be detected by your device before streaks begin to appear, and a display will read that the glass needs to be cleaned.
But the replacement of a drum unit is vital to laser printers` health. A degraded drum unit can cause streaks, smudges, and blank spots on your printed page even if you just inserted a new printer toner. While a broken drum unit won`t break your printer, it will just fail to stop printing at a certain point.
The sponge end of a blocked printer head can be cleaned with only one liquid other than water. This liquid is isopropyl alcohol. Isopropyl alcohol isn`t strong enough to melt the sponge but is still strong enough to dissolve the ink inside the blocked printer head.
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.
One of the most thorough involves soaking the printheads in a solution of water and ammonia for several hours, and then flushing the heads clean by running them under warm tap water. We`ve seen others have success with this method, and it`s cheaper than replacing the printhead assembly.
Fill a bowl with warm water (or a mixture of water and vinegar to clean the printhead) and place the printhead directly in it. Let it sit for five minutes or so. Pull the printhead out of the water and use a lint-free cloth or paper towel to remove the dried ink.
