Abstract: When a laser printer is turned on or awakened from a sleep state and detects a sheet of paper on the paper conveying path, the laser printer performs a process to display a paper jam error upon determining that the sheet of paper should be removed. However, if the laser printer determines based on the detection results from a trailing edge sensor that the sheet of paper was inserted through a manual feed opening, the laser printer determines that the paper need not be removed and, hence, does not perform the process to display a paper jam error.

Abstract: An apparatus for forming an image on a recording medium is disclosed which includes: a first drive source; a photoreceptor driven for movement by a driving force applied thereto from the first drive source; a support member supporting the recording medium to be fed toward the photoreceptor, displaceable between a receiving position allowing reception of the recording medium on the support member, and a feeding position allowing feeding of the recording medium from the support member toward the photoreceptor; and a drive mechanism operable by a driving force applied thereto from the first drive source to displace the support member from the receiving position to the feeding position.

Abstract: An apparatus is disclosed which is for forming an image using a fuser unit, including: a fuser roller; a heater heating the fuser roller; a temperature sensor detecting a temperature of the fuser roller; and a controller controlling the heater to substantially achieve a desired temperature of the fuser roller, wherein the controller includes a desired-temperature setting device. The device is operated during a cold start of the fuser unit, so as to set the desired temperature to a second standby-temperature which is lower than a fusing temperature and higher than a normal standby-temperature, so as to maintain the desired temperature at the second standby-temperature during a heat-storing period during which heat is stored in the fuser unit, and so as to set the desired temperature to the normal standby-temperature upon termination of the heat-storing period.

Abstract: An apparatus for forming an image is disclosed which includes a scanner motor rotatably driving a polygon mirror; a laser light emitter emitting laser light; a generator detecting the laser light reflected off from the polygon mirror, thereby generating a first periodic signal; a generator detecting rotation of the scanner motor, thereby generating a second periodic signal; and a controller performing speed control of the scanner motor, based on at least one of the first and the second periodic signal. The controller makes a first determination as to whether a pre-selected one of the first and the second periodic signal is abnormal. Upon the pre-selected signal being abnormal, the controller makes a second determination as to whether a remaining one of the first and the second periodic signal is normal, and based on a result of the second determination, the controller identifies at least one failed element of the apparatus.

Abstract: A thermal fixing device for fixing toner images onto recording sheets includes a heat member, a pressing member, a temperature sensor, a clock, and a control unit. The control unit performs a toner fixing control and a high-temperature heat-up control. During the toner fixing control, the control unit controls the heat member to heat up to a fixing temperature required to melt toner on a recording sheet disposed between the heat member and the pressing member. During the high-temperature heat-up control, the control unit controls the heat member to heat up to a high-temperature fixing temperature that is higher than the fixing temperature. The control unit sets length of the high-temperature heat-up control in accordance with length of the start-up time measured by the clock.

Abstract: An image forming apparatus includes: an image forming unit that forms an image on both surfaces of a recording medium; and a control unit that controls the image forming unit to form an image so that the image expresses information of a user who uses the image forming apparatus or a job, on a rear surface of a recording medium that includes an image of a first page or a last page of the user's job.

Abstract: A laser printer forms images on a recording sheet fed from a paper cassette. A conveying gap between consecutively fed recording sheets is adjusted such that a conveying gap between consecutively fed thin sheets is larger than a conveying gap between consecutively fed thick sheets.

Abstract: A sheet transporting device includes: a sheet feeding cassette; a transporting unit that transports the sheet from the sheet feeding cassette; a swing member including a swing position, which changes among a first state in which the sheet feeding cassette is separated, a second state in which the sheet feeding cassette is mounted and the sheet is not transported, and a third state in which the sheet is transported; a detecting unit that detects whether the swing position of the swing member is in the second state; and a control unit, wherein when the detecting unit detects that the swing position of the swing member is in a state other than the second state within a predetermined time interval from the time that the transporting unit extracts the sheet from the sheet feeding cassette, the control unit determines that the swing position is in the third state.

When the remote facsimile machine 61 detects circuit connection in S12, the remote facsimile machine 61 transmits in S14 a transmission request signals and a facsimile number of the subject remote facsimile machine 61 to the facsimile device 1. The facsimile device 1 receives in S34 the transmission request signal and the remote facsimile number. The facsimile device 1 calls in S50 the remote facsimile machine 61 based on the remote facsimile number received in S34, and transmits stored image information to the remote facsimile machine 61.

Abstract: Disclosed is a direct dialing number registering method and apparatus including a parent station (facsimile) connected to a communication line and a plurality of child stations (telephones) capable of two-way communication with the facsimile, wherein due to specific identification numbers pre-set for the individual telephones, transmission/reception between the facsimile and a specific telephone can be performed. A direct dialing number for a telephone is registered into the facsimile, before or after the telephone is caused to indicate to a user that the telephone corresponds to the direct dialing number. In another method, the facsimile is set to a dialing number registering mode by operating the facsimile. Then, a telephone for which a dialing number is to be set is caused to transmit its identification number to the facsimile, by operating the telephone. The dialing number of the telephone corresponding to the identification number received by the facsimile is registered into the facsimile.
