Abstract
A printing device includes light guides to assist the user in aligning the device with a reference, such as the edge of a page. The light guides emit a beam of light that produces an illuminated visible straight line segment on the page. The light guides can employ a light source such as an LED, an incandescent bulb, or a laser, and they can use a divergent lens to spread the light into a straight line segment that is projected onto the page.
