Recyclable printing device with tamper protection
First Claim
Patent Images
1. A recyclable device comprising a chassis supporting:
- an image sensor for sensing an image;
a pagewidth print head for printing the sensed image;
an ink supply cartridge for supplying ink to the print head;
a supply of print media on to which said image is printed;
a cutting mechanism for cutting the print media so as to separate the printed images from the supply of print media;
a counter mechanism coupled to the cutting mechanism so as to decrease a counter upon each operation of the cutting mechanism thereby indicating a number of images printed by the print head;
a controller for controlling the device, the controller having high current drive transistors for driving a media transport motor for transporting the print media past the print head and a cutting motor for operating the cutting mechanism, the controller being configured to never operate the high current drive transistors and the image sensor simultaneously; and
a casing surrounding and encasing said chassis so that the ink supply cartridge is unable to be accessed without destruction of the casing, the casing having a slot through which the counter is viewable.

Abstract
A recyclable device comprising a chassis supporting a pagewidth print head for printing an image, an ink supply means for supplying ink to the print head, and a supply of print media on to which said sensed image is printed. A casing surrounds and encases said chassis so that the ink supply means is unable to be accessed without destruction of the casing.
