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 on toner.

  Why it's wrong here

  When a toner cartridge is low, the amount of toner available for transfer to the paper is insufficient, leading to prints that appear faint, streaky, or have blank areas. Ghosting, which involves a faint repeat of a previous image, is not caused by a lack of toner but rather by components failing to properly clean or fuse the image. This issue affects the density and completeness of the current print, not residual images from prior pages.

• ✓

  The fuser unit is worn out and needs replacement.

  Why this is correct

  The fuser unit is responsible for permanently bonding the toner to the paper using heat and pressure. If the fuser's non-stick coating wears out or its heating elements become inefficient, residual toner may not be fully transferred and fused to the current page. Instead, some toner can remain on the fuser roller or pressure roller, subsequently transferring a faint, "ghosted" image of the previous print onto the following pages. This indicates a failure in the final stage of the printing process.

• ✗

  The paper is too moist and causing toner to smear.

  Why it's wrong here

  Excessively moist paper can absorb heat differently, potentially leading to paper jams, curling, or uneven toner adhesion, resulting in a splotchy or smeared appearance on the current page. However, moist paper primarily affects the interaction between the paper and the toner during the current print cycle. It does not cause a faint repetition of an entire previous image to appear on subsequent pages, which is characteristic of a component like the fuser or drum not being properly cleaned or releasing toner.

• ✗

  The printer driver is outdated and needs updating.

  Why it's wrong here

  An outdated or corrupted printer driver can lead to various software-related printing problems, such as incorrect page formatting, garbled text, missing elements, or the printer failing to respond entirely. These issues stem from miscommunication between the computer and the printer's hardware. Ghosting, however, is a physical defect where residual toner from a previous print cycle is transferred, indicating a mechanical or electro-photographic process failure within the printer's hardware, not a software configuration error.
