Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✗

  The toner cartridge is low

  Why it's wrong here

  A low toner cartridge typically results in print output that is consistently faded or light across the entire page, or in specific areas where toner distribution is poor. This occurs because there isn't enough toner available to adhere properly to the electrostatically charged areas of the drum, leading to insufficient coverage. It does not cause ghosting, which is the faint repetition of a previously printed image.

• ✗

  The fuser is overheating

  Why it's wrong here

  An overheating fuser assembly can cause several print quality issues, primarily smearing or toner flaking, as the toner melts excessively and adheres improperly to the paper or the fuser rollers themselves. It can also lead to paper jams due to the paper sticking to the overly hot fuser. However, an overheated fuser does not typically produce ghost images, which are residual images from prior print cycles.

• ✓

  The drum cleaning blade is worn

  Why this is correct

  A worn or damaged drum cleaning blade is a direct cause of ghosting because it fails to adequately scrape residual toner from the photosensitive drum after each print cycle. This leftover toner remains on the drum's surface and is then picked up by the electrostatic charge for the subsequent page, resulting in a faint, repeated image from the previous print job appearing on the current page. The ineffective cleaning allows the previous image to partially transfer again.

• ✗

  The paper is damp

  Why it's wrong here

  Damp paper can significantly impact print quality and printer operation, leading to issues such as frequent paper jams as the moist sheets stick together or warp within the paper path. It can also cause the printed output to appear wavy, curled, or have poor toner adhesion due to the moisture interfering with the electrostatic transfer and fuser bonding processes. However, damp paper does not cause ghosting, which is a specific defect related to residual toner on the imaging drum.
