A method of intermingling images of different sizes on a photosensitive surface and yet avoid the seam of the photosensitive surface and synchronize the transfer of the images to intermingled copy sheets of various sizes by determining the size of each image before projecting the image onto the photo sensitive surface; predicting the relationship of the image to the seam of the photosensitive surface; deciding that a given image would overlay the seam of the photosensitive surface, applying a timing adjustment to project the given image onto the photosensitive surface in avoidance of the seam of the photosensitive surface, and transferring each of the images including said given image from the photosensitive surface to copy sheets whereby images of different sizes are intermingled along the photosensitive surface and copy sheets of different sizes are intermingled along the copy sheet path.

Multi-pitch paper and image handling on seamed belt

A heat and pressure fuser for fixing toner images to substrates. A dual heating lamp arrangement is utilized for elevating the surface temperature of a heated fuser roll. The operation of the dual heat lamps is controlled using dual thermistors for maintain steady state temperature fluctuations to .+-.3.degree. F. The thermistors are positioned, one adjacent the inboard end of the fuse and the other adjacent the outboard end thereof. The outboard thermistor is used to determine the desired on time of the fuser lamp and the inboard thermistor is used to determine which of the two lamps is on. If the inboard temperature is below a predetermined target value a 14 inch lamp is turned on. If the inboard temperature is at or above a predetermined target value an 11 inch lamp is turned.

Dual lamp fuser

An electrophotographic printing machine in which successive electrostatic latent images are recorded on a moving photoconductive belt. Each latent image is adapted to be recorded in a designated region on the photoconductive belt. The designated regions are separated from one another by an inter-image zone. A test patch is recorded in the inter-image zone. The number of designated regions on the photoconductive belt is adjusted so that the size of the inter-image zone is increased enabling a portion of the latent image to be recorded in the inter-image zone without overlapping any portion of the test patch.
