8) As the stock exits the sensor area, continue to slide the stock through the print
stations.
9) Once the stock reaches the feed rollers it may be necessary to hold the feed
pressure knob open in order to pass between the rollers. After exiting the feed
rollers enter the aux. feed and then through the knife into the stacker.
10) Check that the stock is centered and tracking straight through the printer. Adjust
as needed.
11) Close the feed roller and only the print stations needed for the format.
12) Rewind any loose stock back onto the supply roll.
13) Adjust the web guides on the decurler down to the edges of the stock without
deforming the stock.
Butt Splice
NOTE: DO NOT RUN BUTT SPLICES THROUGH THE PRINT STATIONS
The AVERY DENNISON 676 has been designed keeping the operators need to
change supplies quickly and often in mind. Re-threading the stock is quicker than
butt splicing. If however you have determined a butt splice is necessary, after
loading a new roll of stock onto the unwind tape the free ends together. Remove all
slack by rotating the supply roll counterclockwise. To prolong print head life it is
highly recommended that all hand splices be advanced beyond all three print stations
before printing is resumes. This can best be accomplished by using the stock
presently in the print stations to manually pull the new stock through and into the
stacker. Once the butt splice is in the stacker close the feed rollers and those print
stations needed for the format.
NOTE: Whenever stock of a different type or width is put on the printer, a sample
run should be performed. If the print quality / position is acceptable, you
can immediately begin your production run. If the print quality / position
needs to be optimized, refer to the Adjustments section and perform the
procedure needed to make the necessary improvement.
Web Guides
The AVERY DENNISON 676 printer has been designed with the operators needs in
mind. Therefore there are only three sets of web guides in the printer that need to be
changed as the width of the rolls change for various width stocks. Neither of these
adjustments requires a tool.
The first guide is on the unwind itself. A knob located on the front of the unwind
adjusts the width of the guides on the unwind while maintaining center justification.
To increase the width - turn the knob counter clockwise. To decrease the width - turn
the knob clockwise. Adjust the unwind width wider than the roll of stock to be
loaded. Set the stock roll on the unwind between the guides with the stock
unwinding from the top clockwise. Adjust the unwind width down to the stock size
without clamping the core.
The second set of guides are located on the decurler just to the left of the stock
registration funnel. Once a stock is loaded and tracking straight through the machine
adjust this set of web guides down to the edges of the stock without deforming the
