Abstract

Printer platen radius (the distance from a platen's rotational axis to the cylindrical surface) is a critical dimension for platen wear. When the platen radius drops below a certain minimum effective platen radius, it no longer can operate as well and needs to be replaced. A two-tone platen molded from two differently colored materials could solve this issue. The inner material is a first color and molded from the middle axis out to the minimum effective platen radius. The outer material is a second color, visually distinctive from the first color, and is molded on top of the inner material to bring the total platen radius to desired platen specifications. Then as the platen wears down, the outer material is worn and the inner material will gradually show through, thus letting the user know when the platen needs replacement.

Two Tone Printer Platen

     Currently, it is very difficult for a customer to know when a platen needs to be replaced. There are mechanisms in place within the printer to track the amount of media printed since the platen was replaced ("odometers"). However, the odometers have two issues: the "odometers" need to be manually set by the user when the replace the platen (it is not too uncommon for this step to be forgotten), and the odometers are not able to compensate for differences in print head pressure, media abrasion and other mechanical effects which determine platen life.

Often customers do not know to replace worn platens until they experience print issues.
