6) Open the feed rollers by rotating the feed pressure knob counterclockwise.
7) After looping the leading edge of the stock over the decurler slide it through the
web guides. Keep the stock in the center, as the printer is center justified.
8) As the stock exits the web guides, continue to slide the stock through the print
stations.
9) Once the stock reaches the feed rollers it maybe necessary to hold the feed
pressure knob open in order to pass between the rollers.
10) Check that the stock is centered and tracking straight through the printer. Adjust
as needed.
11) Allow feed to close (spring loaded). Close the printheads that are in use. Do not
run a station closed that is not in use. This will cause premature head failure.
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 LKP has been designed keeping the operators need to
change supplies quickly and often in mind. Re threading the stock is quicker than
butt splicing is. 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 the 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 LKP printer has been designed with the operators'
needs in mind. Therefore there are only two 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 require 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
