Adjustments
- Is the proper ink and stock loaded in the printer for the format downloaded?
- Is the strobe setting(s) on the front panel set according to the ink and stock
loaded in the printer?
- Is the ink and stock of known types?
- Are the correct width platen rollers installed in the print stations for the stock
width loaded in the printer?
To actually adjust the tangent continue as follows:
1) Determine the print station that adjustment is needed.
2) Using the sight hole on the front of that print station, observe the present location
of the print line on the print head in relation to the platen roller.
3) As the printer is printing labels use the adjustment thumbscrew to move the head
left and right. Since this adjustment is very precise, do not turn the thumbscrew
more than 1/4 turn before evaluating the results of your adjustment. (See Note)
4) Continue adjusting the thumbscrew until obtaining optimum print quality. Most
stocks and inks print the best with the tangent adjusted to just before top dead
center.
5) Rerun some label to determine if any further adjustment is required, if so repeat
steps three through seven.
NOTE:
The print head mounting block is spring mounted so that tangent
adjustment can be performed without loosening mounting screws.
squarness
If the test pattern, printed on a wide web (4" (100mm) plus), is lighter on one edge
than the other, it is possible that the printhead is out of square. This can also be
detected by looking at the front edge of the print head in reference to the printhead
holder. To remedy this problem, power off the machine and remove the print head
as outlined in the print head installation information. The printhead adjustment plate
has been manufactured so when properly adjusted the head will be square. The
printhead holder has a locator plate that must be slide up snug against the printhead
mount plate. Reinstall the head and it should be square to the web.
Knife squarness
The knife has an adjustment to square the cut to the stock. To make the adjustment,
loosen the two cap screws, one on top of the knife and one below the knife, using the
3/16" ball driver in the tool kit. Move the knife in the direction desired to square the
cut and retighten the screws.
Stacker
The stacker has four adjustments that can be made without a tool to accommodate
different types of stocks.
