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
