Abstract
A sheet transferring apparatus for use in an image forming apparatus including a sheet transferring mechanism and a controller. The sheet transferring mechanism transfers a recording sheet at a transfer speed to an image forming mechanism in the image forming apparatus. The controller determines the transfer speed based on a transfer speed used for an immediately previous recording sheet.
Claims19
A sheet transfer apparatus for use in an image forming apparatus, said sheet transfer apparatus comprising:
- a sheet transferring mechanism configured to transfer a recording sheet at a transfer speed to an image forming mechanism in said image forming apparatus;
- and
- a controller configured to determine said transfer speed based on a transfer speed used for an immediately previous recording sheet.
An image forming apparatus, comprising:
- an image forming mechanism configured to form a visible image on a recording sheet;
- a sheet transferring mechanism configured to transfer the recording sheet at a transfer speed to said image forming mechanism;
- and
- a controller configured to determine said transfer speed based on a transfer speed used for an immediately previous recording sheet.
An image forming system, comprising:
- an image forming apparatus, including,
- an image forming mechanism configured to form a visible image on a recording sheet,
- a sheet transferring mechanism configured to transfer the recording sheet at a transfer speed to said image forming mechanism, and
- a controller to determine said transfer speed based on a transfer speed used for an immediately previous recording sheet;
- and
- an operation apparatus including a display configured to indicate a warning that the sheet transfer mechanism requires an inspection in accordance with an instruction from said image forming apparatus when said transfer speed is varied out of predetermined limits.
An image forming apparatus, comprising:
- an image forming mechanism configured to form a visible image on a recording sheet;
- a sheet transferring mechanism configured to transfer the recording sheet at a transfer speed to said image forming mechanism;
- and
- a controller configured to control a number of revolutions of a motor for driving the transfer roller to determine said transfer speed based on a transfer speed used for an immediately previous recording sheet.
An image forming system, comprising:
- an image forming apparatus, including,
- an image forming mechanism configured to form a visible image on a recording sheet,
- a sheet transferring mechanism configured to transfer the recording sheet at a transfer speed to said image forming mechanism, and
- a controller configured to determine said transfer speed based on a transfer speed used for an immediately previous recording sheet;
- and
- an operation apparatus including a display configured to indicate a warning that the sheet transfer mechanism requires an inspection in accordance with an instruction from said image forming apparatus when said number of revolutions of the motor is varied out of predetermined limits.
