If dots or streaks of a specific color appear at intervals of about 75 mm, the green tube of the image drum is scratched or dirty. Please replace the image drum. If dots or streaks of various colors appear at intervals of about 94 mm, the fuser unit is scratched or dirty. Replace the fuser unit.
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.
Try removing all of the printer`s ink cartridges and replacing them. Print out a few test pages to see if the issue has been resolved. If you are still experiencing skipped lines, try to remove the ink cartridge and replace it with a brand-new cartridge, as this can sometimes alleviate concerns.
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.
Printer`s marks are special marks that are added to your PDF files and to the edge of your parent sheets to assist the offset printing press in proper alignment, trimming, and color values. These printer`s marks are trimmed off once printing is complete. Center Marks. Trim Line.
What Is Banding? Banding is a defect in inkjet printing that will appear as horizontal or vertical lines, streaks or bands in the printed output. Everyone will eventually experience some type of banding with their inkjet printer.
A very small amount of dust or a speck of grime can easily cause lines, streaks, or smudges on your copies or document scans. If you have an MFP (most likely known as, “the copier” in your office), print a blank page first. If there`s still a smudge, you may have an issue with the print assembly on the copier.
These types of lines are typically caused by dirt or white out (correction fluid) on the scanner unit, or one of the corona wires for printing is dirty. This problem is usually resolved by cleaning the scanner glass, scanner glass strip and white plastic bar with a soft lint-free cloth, or cleaning the corona wires.
Faulty and loose connections are the most common cause of horizontal lines on a TV. If you recently moved your TV, you might not have properly connected the cables. This is especially true if you`re using HDMI cables. Loose cables can easily slip out of their ports.
Ghosting is usually considered the presence of a faint image of a design in solid printing areas that is not intended to receive that portion of the image. This print defect is always in the machine direction and usually is a repeated pattern.

ANSWER : At first, try printing the internal demo page of the printer. You will find this under the “Information” Menu. If this page prints ok, the problem is on your computer. Maybe the driver or some application settings. Almost impossible to diagnose from far. Look for a “Reset to Default”-Setting in your driver. You may delete the printer and re-install it with the most up-to-date Driver from OKI. Since the printer is an old one, you may have to look for a “Vista-Driver”, when you’re running Windows 7/8. OKI does not not supply any drivers beyond Vista. I could not find anything about mac drivers …
