Adjusting the Print Heads Replacing and Adjusting the Print Heads

11. Open the printed material and check if the holes on the same color are
exactly on the line of the print. This will help you determine which of
the four colors’ line is the parallel.
12. If the holes on both sides of the printed material are on the printed
side, the P
RINT HEAD is parallel. Adjust the others using this one as a
reference.
If one is almost parallel, adjust the P
RINTING HEAD until it prints parallel
and similarly, adjust the others using this one as a parallel.
The rest of the colors must be adjusted so that they converge onto the
parallel color at both ends.
13. Set to N
O DELAY and print several copies of the “50 Black” file, using all
the colors, and stop after 10 seconds.
Before each experiment of “50 Black” printing, make sure to set the energy
level to 20 for vinyl and 8 for paper as well as warm the heads to 35°C, in
order to get similar results.
14. Check the P
RINT HEAD quality along its entire length.
15. If the print quality of one of the P
RINT HEADS is unacceptable, move the
P
RINT HEAD forward or backward, exactly half a revolution on each side
(half a revolution is equal to 4 bits), until you obtain the optimal
quality.
16. Print a few images to check for wrinkles.
The adjustments for wrinkles are made by physically moving the P
RINT
HEAD forward or backward.
Most adjustments for wrinkles are made in a forward direction.
17. If there are still wrinkles in one of the colors, move the P
RINT HEAD
forward equally on both sides with one clockwise turn of the
A
DJUSTMENT SCREW, and reduce by 8 bits on this specific PRINT HEAD in
the software.
18. Print the “50 Black” file with N
O DELAY and stop after 10 seconds, to
check that the print quality is maintained.
Check if the wrinkles have disappeared. If they have not, repeat this
procedure.
If there still printing quality problems at the center of the print area of
the P
RINT HEAD, after having adjusting it, contact your local distributor.
19. Once all the adjustments have been made and the printing quality is
acceptable along the complete width of all the P
RINT HEADS, print the
longline file and set the D
ELAY and SHIFT of both the X and Y
coefficient on all four P
RINT HEADS, in the CONFIGURATION dialog box.
