  • Toner conservation by PEL modulation with operator control
    Patent number: 5986681
    Abstract: Toner is conserved in printer (1) under operator control by changing the final modulation for each bit in a bit map depending on whether the bit is an edge bit or an internal bit in the character being printed. Since only the final modulation is affected, processing speed and efficiency are not degraded. The operator can select various degrees of internal gray and internal white. Some levels of gray may be satisfactory for some final correspondence.
    Type: Grant
    Filed: September 24, 1997
    Date of Patent: November 16, 1999
    Assignee: Lexmark International, Inc.
    Inventors: Phillip Byron Wright, Dale Randal Danner, Martin Victor DiGirolamo, Gary Scott Overall, John Parker Richey
