Abstract
In one example, a printer having a removably-installable platen. The platen has a platen type. A surface of the platen has a feature that is indicative of the platen type. The printer includes a single platen-type-discriminating sensor. The sensor detects a distinguishing characteristic of the feature. A controller determines the platen type from the distinguishing characteristic.
Claims13
A printer, comprising:
- a first platen removably installable in the printer and having a platen type;
- a surface of the first platen having a first feature indicative of the platen type;
- a platen-type-discriminating first sensor, the first sensor to detect a first distinguishing characteristic of the first feature;
- and
- a controller to determine the platen type from the first distinguishing characteristic,
- wherein the first sensor is further to detect whether the first platen is properly installed in the printer, and
- wherein the controller is further to prevent operation of the printer unless the first platen is properly installed in the printer.

- a surface of the first platen having a first feature indicative of the platen type;
- a platen-type-discriminating first sensor, the first sensor to detect a first distinguishing characteristic of the first feature;
- a controller to determine the platen type from the first distinguishing characteristic;
- a second platen removably installable in the printer, the second platen having a same platen type as the first platen;
- a second feature indicative of the platen type disposed at a surface of the second platen in a location that is the same for all platen types;
- a platen-type-discriminating second sensor, the second sensor to detect a second distinguishing characteristic of the second feature of the second platen, the second distinguishing characteristic indicative of the platen type;
- and
- wherein the controller prevents operation of the printer unless the first platen and the second platen are of the same platen type.
