2.5.3 Cleaning requirements
Due to their compositions, some inks have limitations concerning their cleaning intervals. Especially
inks that contain soot particles also require a more intensive cleaning. With such inks, rinsing the
electrode block and the deflection plates with cleaning fluid may not be sufficient. With such inks, we
recommended cleaning the deflection plates with a soft tissue in order to remove all stains and
particles.
Attention
Due to the higher printing speed of the JET Rapid printers, the number of printouts per
time unit may be much higher than with the JET3up.
Therefore, it is necessary to check the gutter tube for ink staining on a regular basis.
When required the gutter tube has to be cleaned from any ink stains.
Please see the manual and service documentation for the respective cleaning
instructions.
2.6 Print samples
2.6.1 Print samples: JET Rapid in comparison with JET3up – 2D codes
The print samples show that the JET Rapid provides the same print quality as the JET3up but at a
30% higher production speed. The printouts of the JET Rapid are a shade lighter than the printouts of
the JET3up. However, a quality check of the 2-D code shows that the code has the highest readability
level.
JET Rapid
55 µm nozzle
28 m/min
JET3up
60 µm nozzle
20 m/min
PQA (print quality assessment) for the two printouts
JET Rapid at 95% print height
DATAMATRIX 01234 >> PQA from Hand Held Products <<
DATA MATRIX ECC200: 16 x 16 modules in size
Data Field: 12 data & 12 chks in 1 block(s) of GF(256)
X roughly = 0.017"
[A] < Fixed Patterns: 0 module errors
[A] < Data Safety Margin = 83%
[A] < Horizontal Print Growth = -3% of X
[A] < Vertical Print Growth = +19% of X

The PQA does not show any significant differences between the code readability of the two printouts.
