Machine Set Up Sequence
1) Power off the printer, remove the media and ink and thoroughly clean it from the
unwind to the stacker using alcohol and a clean soft cloth. The print heads should
be cleaned as per the Print Head Cleaning instruction section in the manual.
2) Load a full roll of an average width media and ink on the printer.
3) Power on the printer. After passing diagnostics tests the front panel should display
READY FOR BATCHES if not resolve any remaining error conditions.
4) Arrow down to the PRINT / CUT POSITIONS mode and press enter. Cycle
through all the prints, cut, and station two-dot shift values to get a feel for their
present settings.
5) Cycle back to the beginning of the Printer Adjustment and press enter at Print
Checkout Format.
6) Adjust as needed the print head tangent for optimum print quality on all print
stations present. Refer to the Print Head Tangent adjustment section in the manual.
If the machine will not pull stock for this step refer to step number seven.
7) Check the feed pull is 11.0" +- .032" of media. If the feed length is short check
for tight unwind and web guides. After the machine is pulling the correct amount
of media, make sure that the tracking line on the back of the label is at the center of
the stock +- .032" through out the label. If it is not, adjust the outer webguide
postion by loosening the thumb screw under the outer mount block. Rotate the
adjustment nut in or out as needed and tighten the thumb screw. Re-verify that the
label is 11.0" in length. If the print quality is inadequate refer back to step number
six.
8) Using two consecutive labels back-to-back check the squarness of the cut. Adjust
the knife module, as needed referring to the Knife Square adjustment section in the
manual.
9) Using the front panel adjust the print positions so that the print lines for each print
station present is 1.0" +- .032" from the leading edge of the label.
10) If both stations two and three are present, adjust station number two-dot shift on
the front panel so that the tracking line on the front of the label becomes one
continuous line.
NOTE: Once a production sense mark format is loaded, the cut position may be
adjusted which will cause the print to move accordingly.
The machine is now ready for production formats at which time the operator should
need only to fine-tune the prints, cut, and strobes via the front panel.
NOTE: If the machine is used to print on multiple media types the print heads may
need to be adjusted for optimum print quality on each media as they are ran.
