Roller pressure unloading means for a thermal printing mechanism |
摘要 |
A thermal printer having a mechanism for alleviating the pressure between the print head and the resilient roller when the printer is not operational is provided. The printer includes a cam member for camming the print head and resilient roller apart during non-printing in order to prevent a permanent or semi-permanent flat from being formed on the roller because of pressure exerted thereon by the print head.
