A sheet stacking system is disclosed that has improved tolerance for sheets that are not flat. Successive sheets are aligned onto a stack by a plurality of registration belts. The heights of the pivoting registration belts are compared with one another to determine the unevenness of the top of the stack. This unevenness is represented by the difference between the heights of the highest and lowest registration belt &#x394;and is monitored to quantify the planarity of the top of the stack. When the unevenness (&#x394;) exceeds a threshold, the system switches to a modified method to control the elevation of the stack. This method may include stopping the machine from stacking before the unevenness is too large for the registration belts to uniformly drive sheets. This invention prevents the stacker from attempting to stack when sheets are expected to skew thereby preventing jams and unusable stacks.

A printing device, including a fuser section for printing operations and first and second fuser rollers for the fuser section arranged to: displace a plurality of sheets of print material in a process direction; and substantially simultaneously disengage from a trailing edge of a first sheet from the plurality of sheets; and engage a leading edge of a second sheet from the plurality of sheets. A printing device, including: a fuser section for printing operations and including first and second fuser rollers; a motor arranged to rotate the first and second fuser rollers to displace a plurality of sheets of material in a process direction; and a control system configured to measure a torque produced by the motor and according to a value of the measured torque, control a speed at which the first and second fuser rollers displace the plurality of sheets of print material in the process direction.

A paper backed transparency includes a transparency, a paper backing for the transparency and a first adhesive along a leading edge of the paper backed transparency. A second adhesive along a trailing edge of the paper backed transparency is disclosed to limit movement between the transparency and the paper backing during duplexing.

A mechanism for supporting said light-emitting device in said reproduction apparatus in an electrographic reproduction apparatus having a light-emitting device for forming, on a dielectric support member, a charge pattern corresponding image-wise to information to be reproduced. The light-emitting device support mechanism includes a carriage attached to the reproduction apparatus and movable relative thereto to a first operative position and a second remote position. A pivot mechanism is supported by the carriage so as to provide a pivot axis, the light-emitting device being mounted on the pivot mechanism for movement about the pivot axis. A reference feature is located in the reproduction apparatus, the reference feature located in a predetermined relation relative to the dielectric support member. A movable latch member is selectively engagable with the light-emitting device to move the light-emitting device from a first position, remote from the reference feature, movable with the carriage to the first operative position or the second remote position, to a second position in engagement with the reference feature to be operatively associated with the dielectric support member.

A reproduction apparatus including a transfer drum for electrostatic transfer of a toner image from an image bearing member, and a transfer drum cleaning mechanism. The transfer drum cleaning mechanism comprises a member for wiping the surface of the transfer drum to remove residual toner and debris therefrom. The wiper is selectively movable into operative relation with the transfer drum surface. A blade member is provided for removing toner and debris from the wiper. The blade member is resiliently urged into association with the wiper under substantially uniform load.

An apparatus and method for sequence a 'two-up' imaging drum for four color process color is provided. The sequencing provides enough separation between the receivers to operate an image fixing station as a slower throughput speed then the linear speed of the receivers exiting the transfer station and thereby provide more fusing energy and higher image quality without appreciable loss in productivity. The sequence also provides for better registration, by maintaining the receiving member conforming to the transfer drum during the total toning process.
