5.3 .......Feed Belt - Adjustment<br />
The feed belt must be correctly tensioned for correct operation. If<br />
under tensioned, the belt will 'track off' the rollers and if over<br />
tensioned, the sidelay will be difficult to position across the feed<br />
bed when changing paper size.<br />
The adjustment must be set equal on each side, gauged by<br />
checking the gap in each bracket as indicated in fig. 5.21.<br />
The feed belt tension is checked by raising the feed bed on the gas<br />
strut and measuring the distance from the middle of the belt to the<br />
bed,which when correctly tensioned, is typically 41mm.<br />
To adjust the tension, use a 10mm wrench on the adjusting nuts but<br />
ensure that each side is adjusted equal amounts as the gap in the<br />
adjusting brackets as indicated by the arrows in fig. 5.21 must be<br />
equal both sides of the machine.<br />
