W983 Stacker/W863 Dryer Operating Guide
Stacker Setup Guidelines
The following are guidelines to consider when making your Stacker Job Setup adjustments.
Media Stop, Stacker Height and Distance
The Stacker height and distance adjustments and the media stop adjustment are set so that the leading edge of the mailpiece contacts the conveyor belt as close to the media stop as possible, while the mailpiece is being released from the output rollers of the printer.
If the mailpiece contacts the conveyor belt too soon, skewing will occur. The general rule is that at slower speeds, the longer the mailpiece is, the Stacker is positioned lower and farther away from the printer output. While at higher speeds and with shorter mailpieces, the Stacker is positioned higher and closer to the printer output.
The media stop is set closer to the printer for short mailpieces and farther away for longer mailpieces.
Hold Down Assembly
The function of the large rollers is to provide drive and control of the mailpiece as it transitions to the stacking conveyor. The rollers should be positioned in such a way that they retain the mailpiece but do not come in contact with the address zones. If positioned in the address zones, the rollers will cause smudging.
The function of the springs (retainers) is to control the mailpiece as it lands on the stacking conveyor. The general rule is that with thinner, slower moving mailpieces, the retainers should be positioned close to the deck. In the case of thicker, faster moving mailpieces, the retainers should be positioned higher off from the deck.
Full Arm Fixture and Full Arm Tip
These adjustments need to be made so that the “Stacker full” indicator switch functions correctly while allowing the maximum number of mailpieces to be stacked.
The position of the full arm fixture is dependent on the width of the mailpiece. The wider the mailpiece, the farther up the ramp the fixture needs to be set. The position of the full arm tip is dependent on the length and thickness of the mailpiece. The general rule is that the shorter and thinner the mailpiece is, the less the tip is extended. While the longer and thicker the mailpiece is, the more the tip is extended.
