I see you are also in Australia - Contact me, if you wish at Cheers, Don't overlook lubing the felt wipers on the print shaft. Thats the one with the groove in it that holds the carrier. Just drop some 3-in-1 oil on the shaft and tab/carriage return it a few times. This should make the carrier escape faster. As was pointed out in an earlier post there are two spring clutches under the plastic cover on the right hand side if the tension spring is broken, the CR is real slow. Don also ex IBM service |
