Laser Printing Process

Correct Answer: Clean or replace the paper feed rollers.

The most likely cause of repeated paper jams in a laser printer is worn or dirty paper feed rollers. These rollers pull the paper from the tray and feed it through the printer. If they are worn or coated with dust and debris, they can slip or fail to properly grip the paper, leading to misfeeds and jams. Updating the printer driver, adjusting power saving settings, or calibrating color settings would not resolve a mechanical issue like worn feed rollers. Therefore, cleaning or replacing the paper feed rollers is the best solution to resolve recurring paper jams in a laser printer.

Correct Answer: Toner cartridge is low on toner and needs to be replaced.

The most likely reason for faded prints from a laser printer is that the toner cartridge is low on toner. When the toner level is low, the printed output becomes faded or lighter in appearance. Replacing the toner cartridge with a new one should resolve the issue and restore print quality. A dirty printer drum may also cause print quality issues, but typically results in streaks, spots, or other artifacts on the printed page rather than uniform fading. Restarting the print server or refilling the paper tray would not resolve the issue of faded prints.

Correct Answer: Faulty imaging drum and it needs to be replaced.

Ghosted images on prints from a laser printer are typically caused by a worn-out or faulty imaging drum. The imaging drum is responsible for transferring the toner onto the paper during the printing process. Over time, the surface of the drum can become scratched or damaged, leading to ghosting issues. Replacing the imaging drum should resolve the problem. Incorrect print settings or outdated printer drivers are unlikely to cause ghosting, as they primarily affect print quality or compatibility. Low toner levels may result in faded or light prints, but not ghosted images.
