To understand this, it&#8217;s helpful to review the basic steps in the laser printing process, which includes <strong>charging, exposing, developing, transferring, and fusing<\/strong>.<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Charging<\/strong>: The <strong>primary corona<\/strong> or <strong>charge roller<\/strong> applies a uniform negative charge to the <strong>photosensitive drum<\/strong>.<\/li>\n\n\n\n<li><strong>Exposing<\/strong>: A laser beam writes the image by altering the charge on specific parts of the drum, creating an electrostatic image.<\/li>\n\n\n\n<li><strong>Developing<\/strong>: Toner particles are attracted to the areas of the drum where the laser has reduced the charge.<\/li>\n\n\n\n<li><strong>Transferring<\/strong>: This is where the <strong>transfer roller<\/strong> comes in. It is located directly underneath the drum. As the paper passes through, the transfer roller gives the paper a <strong>positive charge<\/strong>. Since toner particles on the drum are negatively charged, they are pulled toward the positively charged paper.<\/li>\n\n\n\n<li><strong>Fusing<\/strong>: Finally, the <strong>fuser<\/strong> melts the toner onto the paper using heat and pressure, making the image permanent.<\/li>\n<\/ol>\n\n\n\n<h3 class=\"wp-block-heading\">Why the Other Options Are Incorrect:<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Drum<\/strong>: The drum holds the electrostatic image and carries toner but does not charge the paper.<\/li>\n\n\n\n<li><strong>Fuser<\/strong>: This component applies heat to permanently bond the toner to the paper, not to attract toner.<\/li>\n\n\n\n<li><strong>Primary Corona<\/strong>: This charges the <strong>drum<\/strong>, not the paper.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Conclusion:<\/h3>\n\n\n\n<p>The <strong>transfer roller<\/strong> is specifically designed to <strong>charge the paper<\/strong> so it can <strong>attract and hold the toner<\/strong> particles from the drum.
