WHAT HAPPENS IF A PRINTER DRUM RUNS OUT

Photosensitive drums are a feature of the printing process used by laser and LED printers. The drum in these printers builds up an electric charge where the light hits it because they flash the page pattern onto the drum. The toner is then transferred to the paper by the drum by picking it up where it is charged. The chemicals in the drum can lose their potency and the surface of the drum can be harmed before an electrical charge in the printer resets them.

  1. Printer Stops Printing

The number of pages that the drum has produced is often monitored by sensors in printers. The sensors often alert you that your drum needs to be replaced whenever they reach a certain threshold and eventually prevent printing until the drum is changed. This makes it less likely that a failing drum would provide output of poor quality.

  1. Faded or Blurry Prints

The constant charging and discharging cycle, together with the electrical charges that printers employ, can eventually cause the chemicals in an image drum to degrade. The drum’s ability to draw toner becomes less as the chemicals degrade, and the boundaries between charged and uncharged regions become increasingly hazy. This results in printouts that have grey instead of black parts and fuzzy borders.

  1. Lines on Prints

The majority of printers feature built-in wipers that remove any remaining toner from the drum since the drum is designed to have a smooth, clean surface. However, certain drums may become scratched or accumulate toner deposits over time. Thin vertical lines caused by these deposits on printouts may be an indication that the drum needs to be changed since it is damaged.

  1. Spots and Blotches on Printouts

Drums can pick up stray dirt flecks as they age and get unclean. These blemishes have the ability to either contribute more toner to the pages or stop toner from being transferred. Both of these problems with print quality may indicate that the drum needs to be changed.
