摘要： A method and apparatus for controlling conditions in a printer that includes a print engine that is operative upon an article to print marks upon the article. Sensors are provided for detecting relative humidity and temperature within a moving air stream in the printer. A controller in the printer determines if the detected relative humidity within the apparatus falls within a range of acceptable relative humidities and the detected temperature within the apparatus falls within a range of acceptable temperatures. The range of acceptable relative humidities and acceptable temperatures defines a predetermined target area. When outside the range of the predetermined target area a determination is made of needed minimal adjustments to bring the temperature and humidity within the target area. Subject to such a determination, mist and/or heating of the air stream are provided to implement the needed adjustments.

摘要： Image-forming apparatus includes a finite length image member such as a seamed photoconductive loop. Images are formed on the image member in one of three different sized image frames, the first image frame being 1/2 the in-track length of the third image frame and the second image frame having an intermediate length. Relatively small size images, for example letter size images are formed in the first size frames while relatively large sized images, for example, ledger sized images are formed in the third size frames. Intermediate sized images, for example images for B-4 receiving sheets are formed in the second or intermediate size image frames. Receiving sheets in duplex are passed through a finite length duplex path which has a speed profile which is substantially the same for receiving sheets bearing images formed in the first and third frame lengths but is different, for example faster, for images formed in the second size image frame while use of the same duplex path for the three frame sizes. Sheets are fed into an inverter in the duplex path at a faster speed than is used for most of the rest of the duplex path. After a delay in the inverter, sheets are fed out of the inverter at a substantially reduced speed more easily handled by the downstream portion of the duplex path.

摘要： A sheet transporting apparatus for transporting document sheets, wherein passive gripper gates, of simplified construction, selectively attach a sheet to the transport belt of the sheet transporting apparatus. The sheet transporting apparatus comprises a transport belt having a passive mechanism for selectively clamping a document sheet thereto. The transport belt is moved along a path, and a sheet is delivered into association with the passive clamping mechanism. The passive clamping mechanism is selectively actuated to clamp a sheet delivered into association therewith to the transport belt for movement with the transport belt. A mechanism, located downstream in direction of movement of the transport belt, selectively deactuates the passive clamping mechanism to release a sheet from the clamping mechanism of the transport belt. Thereafter, the sheet is separated from the transport belt.

摘要： A transfer roller apparatus for use for example in an electrographic copier including a dielectric member adapted to carry electrostatically developed marking particle images on successive image receiving areas. The transfer roller apparatus, is driven to synchronize transfer roller rotation with dielectric member movement for accurate transfer of marking particle images to a receiver member on such roller peripheral surface. The roller transfer apparatus includes a gear train having a first gear coupled to a rotational motive source and a last gear coaxially coupled to the transfer roller. The transfer roller is articulatable to a first position in operative relation with the dielectric member, a second position in operative relation with a cleaning mechanism for the peripheral surface of the roller, and a third rest position intermdiate the first and second positions. Articulation of the transfer roller is effective about an axis which is coincident with an intermediate gear in the gear train whereby the gears in the gear train remain in mesh during articulation of the roller to maintain the synchronous relationship between the roller and the dielectric member.

摘要： An electrophotographic printer/copier comprises a photoconductive drum assembly and an optical writer for projecting a rectilinear line of image information onto the drum's photoconductive surface. Both subsystems share the same pair of mechanical fiducials for precisely positioning these subsystems in the printer frame. According to the invention, the optical writer is movably mounted on the fiducials to adjust the skew of an image line projected onto the drum.
