Some color copier configurations require "multi-pass transfer", which means that each sheet is routed a number of times through the same xerographic transfer zone. A different color - separation image is put on the sheet with each pass. The sheets are firmly held by a roll or loop recirculating mechanism to maintain registration between transfer passes. Up to four color transfers are done (cyan, magenta yellow and black), involving a like number of passes for each sheet. After all of the colors have been received, the sheet goes through a fuser station to fix the combined image to the sheet.
