Abstract
A feed mechanism for a wide format printer is provided having a supply spool for supplying media web to a printhead, a take-up spool for receiving the web after printing, a take-up motor connected to the take-up spool, a take-up control system for controlling the take-up motor torque, a drive roller system positioned between the supply and take-up spools, a drive motor connected to the drive roller system, and a braking motor connected to the supply spool for generating tension in the web between the supply spool and the drive roller system. The take-up, drive and braking motors are separate motors and are separately connected to the take-up spool, drive roller system and supply spool, respectively. The web fed from the drive roller system to the take-up spool is maintained under substantially constant tension by regulating the torque of the take-up motor using the take-up control system.
