How to Identify and Fix Common Problems ?

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.
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.
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.
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.
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.
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.
Banding can occur if you use inkjet media that isn`t compatible with your printer and ink. Other possible causes of banding include: (1) using the incorrect media settings in the print software; (2) misaligned printheads; and (3) clogged nozzles in the printhead.
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.
The most obvious is most common on laser color printers and can be detected by a flashing message on the printer display screen. Other signs of a bad printer drum include printing blank pages, printing gray pages and strange sounds coming from the printer as it prints.
Priming. Sanding alone can reduce the appearance of layer lines by shaving off the raised “steps,” but another approach is to fill in the crevices with primer spray then sand down the excess primer afterwards. This method works well because primer is easier to sand than PLA itself.
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.
Most laser printers today have a default resolution of 600 x 600 dpi, which is fine for everyday text printing. For sharper output when printing photographs or documents combining text, photos, and charts, a higher resolution, such as 1200 x 1200 dpi or 2400 x 600 dpi, is preferable.
Why is it important to clean a laser printer? 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.
Hold a piece of lens tissue above the mirror and place a few drops of acetone on the paper. Lower the lens tissue onto the optic and pull it over the surface. Note that the dry part of the tissue helps remove acetone residue. Repeat the above step until the optic is clean.
What maintenance does a laser printer need? To keep your printer running at maximum capacity, you need to maintain its working parts. Dust and wipe it down regularly inside and out with a no-lint towel and rubbing alcohol. Turn off your printers regularly, especially when they aren`t in use for a long while.
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.
Algae commonly cause streaking and staining on roofs. The dark color that appears as a black stain is caused by a specific type of algae called gloeocapsa magma. This growth is a type of bacteria that forms when algae spores group together.
Horizontal smearing shows that the ink tank`s bottom is clogged with fibers. If you discover a problem like this, remove the cartridges and begin cleaning them. Your ink cartridges may have dried out or the print heads may have become clogged with ink residue if they are older than a year.
There are many factors that determine the actual drum life, such as the temperature, humidity, type of paper, type of toner used, number of pages per print job and so on. Under ideal conditions, the average drum life is estimated at approximately 12,000 pages.

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.

the most relevant questions and answers related to your specific issue

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.

lexmark C544 prints yellow streaks
ANSWER : Are the streaks repeating defects or does it run top-down on the right or left side of the paper ?If you have a vertical yellow shade on the paper, it’s probaly the yellow developer unit which causes the problem. You then can either replace the developer only or (depending on the total number of pages printed, check the statistics !) the complete imaging kit which consists of all four developers and the imaging basket with the Photoconductors.If you see a repeating defect, you should at first print out the print defects page (menue\reports\print defects). Compare the yellow streaks with the printed scales. Above the scales it tells you which component should be changed.

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.
