Image transfer element with leverage

An image transfer mechanism for a printer having a frame and an imaging element attached to the frame, the image transfer mechanism comprising:

• a load arm movable with respect to the frame;
• a transfer roller arm having a proximal end portion and a distal end portion;
• a transfer roller having an axis of rotation attached to the transfer element arm;
• wherein a proximal end portion of the transfer roller arm is attached to the movable load arm so that the load arm urges the transfer roller toward the imaging element;
• and
• an engaging mechanism for selectively moving a distal end portion of the transfer roller arm in an engaging direction to urge the transfer roller toward the imaging element.

An image transfer mechanism for a printer having an imaging element, the image transfer mechanism comprising:

• a transfer roller arm having a proximal end and a distal end;
• a transfer roller attached to the transfer roller arm between the proximal end and the distal end of the transfer roller arm;
• an engaging mechanism for selectively moving the distal end of the transfer roller arm toward the imaging element;
• a load arm having a proximal end and a distal end;
• wherein the proximal end of the transfer roller arm is attached to the load arm between the proximal end and the distal end of the load arm;
• and
• wherein movement of the distal end of the load arm in a loading direction urges the proximal end of the transfer roller arm toward the imaging element.

An image transfer mechanism for a printer having a printer frame and an imaging drum attached to the printer frame, the image transfer mechanism comprising:

• a roller arm having a proximal end and a distal end;
• a transfer roller having a longitudinal axis, wherein the axis of the transfer roller is rotatably attached to the roller arm between the proximal end and the distal end;
• a load arm having a proximal end and a distal end;
• wherein the proximal end of the roller arm is attached to the load arm between the proximal end and the distal end of the load arm;
• wherein the proximal end of the load arm is pivotally attached to the printer frame;
• a load mechanism for applying a load force to the distal end of the load arm to urge the load arm against the proximal end of the roller arm to urge the transfer roller toward the imaging drum;
• and
• an engaging mechanism for selectively urging the distal end of the roller arm toward the imaging drum;
• wherein movement of the distal end of the roller arm toward the imaging drum causes the proximal end of the roller arm to press the load arm against the load force provided by the load mechanism.
