Filed:

Sep 7, 2005

Appl. No.:

11/220945

Inventors:

Gregory Ream - Lexington KY, US
Michelle Morris - Lexington KY, US
William Menk - Lexington KY, US

International Classification:

G03G 15/06
G03G 15/08

US Classification:

399055000, 399284000

Abstract:

A method and apparatus to clear the accumulation of toner particles from a doctor element by periodically reversing a bias field between a doctor element and a developer member. The developer member may be biased to a first electrical potential while the doctor element may be biased to a second electrical potential. The second electrical potential may be higher than the first electrical potential. The doctor element and the developer member may be biased from a single voltage supply and a voltage dividing circuit. A bias reversing circuit may cause the second electrical potential to fall, at least temporarily, below that of the first electrical potential when power from the voltage supply is removed. The bias reversing circuit may also cause the first electrical potential to fall with a longer time constant than that of the second electrical potential when power from the voltage supply is removed.

US Classification:

399088000

Abstract:

A power supply control system for a fuser assembly in an electrophotographic apparatus includes a power supply and a fuser assembly. The power supply includes a first electrical path designated for a fuser assembly that operates at a first voltage and a second electrical path designated for a fuser assembly that operates at a second voltage. The fuser assembly is configured to operate at a select one of the first voltage or the second voltage and is connected to the first electrical path if the fuser assembly operates at the first voltage, and the fuser assembly is connected to the second electrical path if the fuser assembly operates at the second voltage. The first and second electrical paths allow different device features including power limiting devices such as fuses, switches, relays, etc., to be placed in each path.

International Classification:

A45D 1/28
A45D 1/04

Abstract:

A hair iron includes two longitudinally extending arms each having a ceramic heater. Users place hair between the heaters during use. A controller coordinates heating conditions of the heaters. If a line voltage supplied to the hair iron is a high voltage, the controller is configured to alternate heating between the heaters whereby only heating of one heater occurs at one time. To reduce flicker and harmonics, the controller supplies heating current so that one heater remains off for consecutive half-cycles of alternating current while the other heater is powered on variously. The controller then switches the heating. The hair iron further includes a line voltage detector to detect whether a line voltage supplied through a cord to the hair iron is either low voltage or high voltage. During such time, the controller limits heating power to the two heaters.

International Classification:

A45D 1/04

Abstract:

A hair iron includes two longitudinally extending arms each having a ceramic heater. Users place hair between the heaters during use. A controller coordinates timing and voltage conditions to heat the heaters to avoid light flicker and power harmonics. Thermistors provide current heater temperatures of the heaters and a controller calculates a desired heating power. The heating power includes application to the heaters of various half-cycles of AC power from an external AC line voltage.
