Dell Laser 3760N
My Dell C3760n color laser printer has been having a few problems recently that I assume are related to a common cause:
Experienced technical support provide their insights in answering this question :
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.
How to Identify and Fix Common printer Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced technical support :
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.
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.
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.
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.
A printing defect characterized by elongated blotches of ink in non-image areas, commonly caused by mechanical problems with the press, such as damaged rollers (in lithography), or by improper wiping of a gravure cylinder by the doctor blade (due to dried ink fragments attached to it, or other such problems).
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.
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.
Adjust the application settings and the printer settings to the highest possible resolution. Both of these features can typically be accessed from the “Print” menu. Dpi settings can range between 72 dpi and 2400 dpi. Choose the highest dpi setting available for best results when using a laser printer.
Paper Jams
This is a common laser printer problem. Primary causes include grime, dust, worn rollers, or incorrect paper weight. The most basic way to prevent paper jams is simply through regular cleaning of your printer. Also, replace parts as needed.
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.
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.
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.

Print Quality Issue (Streaks and Ghosting)

Laserjet 4250 print quality issue (see image)
ANSWER : It looks like a fuser problem. One way to prove it is with the half-stop test. Put a sheet in the drop down manual feed tray. Send a print job and watch the paper. When the end of it is about to enter the printer, open the lid and take out the toner cartridge. Look at the printed image. If it looks OK, then it is a fuser problem. If not, then it is a toner cartridge issue since it hasn’t gone through the fuser.

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.
