Electrical Trouble Shooting / Machine Set Up Sequence
If the printer is mechanically operable, proceed as follows:
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 head should
be cleaned as per the Print Head Cleaning instructions 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 test one and two the front panel
will display READY FOR BATCHES.
4) Arrow down to the setup mode and press enter. Set the print, cut, and strobe to 0.
5) From the host PC download a batch of 1000 labels using the 6X6 setup format 92.
6) Adjust as needed the print head position and then pressure for optimum print
quality. Refer to the Print Head Adjustment section in the manual. If the machine
will not pull stock for this step refer to step number seven.
7) Adjust the feed pressure to pull 11.0" +- .032" of media. Refer to the Stock Feed
Adjustment section in the manual. After the machine is pulling the correct amount
of media, measure the distance between the top of the media and the tracking line.
This distance must be .5" +- .032" through out the label. If it is not, first check and
adjust as needed the unwind core guide, and the web guide, then if needed adjust
the feed pressure from side to side until it is. 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 squareness 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 physical cut to be 1.0" +- .032" from the cut line
on the label. The machine is now ready for production formats at which time the
operator should need only to adjust the print, cut, and strobe via the front panel.
NOTE: If the machine is used to print on multiple media types the print head may
need to be adjusted for optimum print quality on each media as they are ran.
