Xerox Disclosure Journal
An improvement to a prior art printer is disclosed which provides a cost improvement and a solution to the static shift problem. With reference to the prior art of Figure 1, the cables are coupled to the printer carriage (not shown) through a pulley arrangement 18 which is mounted on an axle 17 which, in turn, is mounted for rotation on the printer carriage. Cable segments 13 and 14 are wrapped around the grooves of pulley 18 in opposite directions with their remaining free ends coupled to the frame 40; in the case of segment 13 to spring 19 and in the case of segment 14 to fixed fastener 38. Spring 19 provides for the take-upof any slack in either of the cables which might occur due to long-term temperature drift. Cable segments 13 and 14 are changed in direction by idler pulleys 13 and 16, respectively. Cable segments 13 and 14 are also wrapped around the grooves of pulley 11, with pulley 11 being mounted on shaft 12 of motor 10.
