3.1.4 Ink drops falling on media from heads during printing
Step 1 : Never remove cartridges out of the printer when it’s uncapped!
If cartridges are removed when the machine is not on it’s capping station, ink will leak out from
heads and air will be sucked through the cartridge-needle.
Step 2 : Once air-bubbles inside the tubing, the risk of smudging and destroying the print is possible!
Step 3 : To solve: proceed with ink load to remove all ink-bubbles from the tubing

Step 4 : Avoid dust particles below the printer heads by any means. 1 piece of dust on the nozzle-plate
will suck out ink from the heads resulting in ink drops.
Avoid placing the printer in dirty and dusty environments. Clean the machine on a regular basis.
Step 5 : Verify if wipers are in good shape. After wipe action, before printing, verify if the nozzle-plate
around the nozzles, is 100% clean. If not, clean the wipers. If the wipers are not straight
anymore, replace wipers.
Step 6 : The printer is a high-precision instrument that needs care and maintenance, this due to the
nature of the solvent inks.
Be sure to respect the recommended daily maintenance procedures according to the ink used, to
assure optimum performance.
Step 7 : Respect the environmental conditions as described in the installation guide. During winter-time
and cold periods, low environmental humidity will decrease print performance.
Step 8 : Place the machine in an antistatic location. Antistatic flooring is recommended.
Step 9 : All electronical equipment (printer + computer) must be properly earthed.
Step 10 : Very Low environmental humidity also causes plastic materials like banner and vinyl’s to charge
statically. Statically charged materials might cause printing anomalies like:
• Ink drops
• Nozzle inaccuracy and deflection
• Bad printing quality
Step 11 : Printing materials need to be climatized in the same environment as the printer for at least 8
hours, before being ready for printing.
Step 12 : Always use the latest released Firmware version.
