15. Reduce the Print Speed value through the QUICK SETUP
or MEDIA CONTROL menu or via host software. (Refer to
the User's Manual .)
16. Power off the printer. Remove the printhead and inspect it
for contamination (adhesive material, ribbon and media
residue line buildup), wear, or damage. A worn printhead
will show obvious impressions or indentations in the light
brown heating element area where ribbon or media made
contact. A damaged printhead may have nicks, scratches,
grooves, or cracks. If no problem is visible, install the
printhead and repeat step 7.
17. Install an alternate printhead if one is available and repeat
step 7.
18. If possible, install the questionable printhead in another
printer and repeat step 7.
19. If the void areas in test print patterns remain in the same
location, replace the printhead.
1. Power off the printer and thoroughly clean the printhead
with a cleaning pen or isopropyl alcohol and a cotton
swab.
2. If problem persists after cleaning the printhead, inspect the
printhead for damage and replace it if necessary.
