  • Control of photoreceptor belt detensioning cycles using extended slower belt rotation
    Patent number: 8768216
    Abstract: A processor places a printer apparatus in a reduced activity mode after printing requests have not been received for an “inactivity” time period. A belt support device rotates a photoreceptor belt at a reduced speed when the printer apparatus enters the reduced activity mode and for a “delay” time period after the printer apparatus enters the reduced activity mode. The belt support device returns the rotational speed of the photoreceptor belt to the original speed if a new printing request is received during the delay time period. However, the belt support device stops rotation of the photoreceptor belt and reduces the belt tension if the delay time period expires without receiving a new printing request.

  • Methods for in situ applications of low surface energy materials to printer components
    Patent number: 8690288
    Abstract: In an inkjet printer, a low surface energy material is applied to a printhead face and a drip bib during a printhead maintenance operation. The low surface energy material forms a thin layer on the printhead face and drip bib to resist adhesion of ink to the printhead. The low surface energy material can be a layer of silicone oil.

  • Drawer latch flexure mechanism
    Patent number: 8032053
    Abstract: A latch apparatus has a latch base, a latch frame, and at least one flexible bracket connecting the latch frame to the latch base. Connectors are used to connect the flexible bracket to the latch frame and connect the flexible bracket to the latch base. The connectors prevent the outer surface of the flexible bracket from moving along the surface of the latch frame or the surface of the latch base. A biasing member is connected to the latch base and the latch frame. The flexible bracket maintains a gap between the latch base and the latch frame and prevents the latch base from contacting or sliding along the latch frame.
