Printhead Cleaning Procedure
While wearing approved, solvent resistant gloves: Remove the printhead cover tube and hold the
printhead as shown below. Place a suitable container underneath and wash the entire printed circuit
board (PCB) surface with the appropriate solvent. Do not use the wrong solvent; make sure it is the
solvent corresponding to the ink type being used in the printer.
Simply squirt the solvent in short bursts onto the affected parts with a short delay between bursts
to allow ink to dissolve. The surplus solvent will run down the printhead and can be collected in the
container for disposal.
Allow the printhead to dry completely by letting it stand for a few minutes. Do not dry the printhead
with a cloth or towel as this may leave fibres that could interfere with the printed drops. Particular
care should be taken to ensure that the space between the nozzle and charge electrode is free of
solvent. If not, it can usually be removed by inverting the wash bottle and blowing off the excess
solvent.
WARNING: MOST INK BASES ARE FLAMMABLE. IT IS THEREFORE IMPORTANT TO DISPOSE
OF THE WASTE CLEANING FLUID IN ACCORDANCE WITH LOCAL REGULATIONS.
CAUTION: Do NOT be tempted to immerse the printhead in solvent or an ultrasonic bath. THIS
MAY DAMAGE THE PRINTHEAD AND WILL VOID THE WARRANTY.
