CLEANING THE PRINT HEAD
1. Turn the printer off and remove the power cable.
2. Open the Top and Side Access Doors.
3. Open the Print Head Assembly by rotating the
Head Latch toward the back of the printer. The
Print Head Assembly is spring-loaded and will
automatically open as soon as the Head Latch
is disengaged.
4. Remove the ribbon.
5. Apply
PANDUIT
Cleaner to a cotton swab.
6. The Print Head faces downward along the front
edge of the assembly. Pass the end of the dampened swab along the epoxy ridge that runs the entire width
of the Print Head.
7. Check for any black coloring or adhesive on the swab after cleaning.
8. Repeat if necessary until the swab is clean after it is passed over the head.
9. The head should be cleaned at least every time the ribbon is changed and more often in dusty environments.
PRINT SPEED
The other method of controlling print quality is by controlling the speed at which the label is printed. This
adjustment is made only on an individual label basis using the Print speed command code. Changing the print
speed allows the user to control the amount of time allowed for print element cooling before the media is
stepped to the next print position. It is especially critical when printing “ladder” bar codes (bar codes printed with
the bars parallel to the print line). When printing a “ladder” bar code, it is important to allow the head to cool
sufficiently before stepping to the next position. If it does not have sufficient time to cool, the bar will be
“smeared” on the trailing edge.
The Print Speed can be set using the LCD panel or with the Print speed software command. The software
command will override the any setting entered using the LCD panel. The other method of controlling print quality
is by controlling the speed at which the label is printed. This adjustment is made only on an individual label basis
using the Print Speed command code.
