Marking speed
The default marking speed for the ink jet
printer is 2000 mm/min. The quality of
the marking depends on the speed and
air pressure. If the speed is too high, the
marking will be fainter, if the speed is too
low, too much ink will be used and the
chances of the nozzles clogging up will be
increased. The speed can be adjusted in
the settings. Faint markings could also be
due to other causes such as insufficient
ink, insufficient pressure or blocked
nozzles. More information about checking
and maintaining the systems follows.
Hardware settings
The hardware consists of a printer head,
a controller and an ink reservoir. There
are two pressure systems, the software
controls which pressure is used for which
function. The default settings are shown
in the table below:
Printer function Pressure system
Mark line Low pressure system
Footprint Low pressure system
Mark text High pressure system
The REA ink jet printer controller and reservoir
Turn the knobs to adjust the low and
high pressure to between 0.2 and 0.5
bar, read the actual working pressure
from the gauge. Increase or decrease the
dot size to achieve the desired printing
result.
Always check the ink level in the
reservoir before printing. Always keep
the level between the minimum and
maximum level markers, never overfill
the reservoir.
Cleaning and maintenance
Always make sure the printer head is
clean before starting to print. Wipe the
nozzle plate with a lint-free cloth soaked
in the cleaning fluid that was supplied
with the machine (CL-TKDK). Check the
reservoir, is there enough ink to complete
the job? Check that the nozzles are not
clogged. Pass a piece of paper under
the printer head and push the purge
button on the top of the printer head.
The dots should all be the same size. If
some are smaller or missing altogether,
then these nozzles are probably clogged
and will need cleaning. Take the printer
head out and turn it upside down, so
that the nozzles are facing upwards.
Spray cleaner on the clogged nozzles and
allow it time to react. Wipe clean and try
testing again. If there is no improvement
the nozzle plate will have to be cleaned,
the procedure is explained later in this
chapter. If the top nozzles do not print,
there may be air in the system, the
procedure for venting the system is also
explained in this chapter.
