Abstract
There is disclosed a carriage control apparatus for a serial, impact computer printer. The carriage control apparatus comprises an encoder disk mounted for rotation on the carriage and having a coded pattern on its periphery, a photo sensor (and associated light source) for detecting the coded pattern and a drive means, preferably a serpentine toothed belt attached at each end to the printer's side frames that engages a sprocket wheel attached to the encoder disk to rotate the encoder disk in a fixed relationship to the carriage's position along the line of print of the printer.
