Ultrasonically Clean a Nozzle Plate

An Ultrasonic Bath should be used to clean a Nozzle when a backflush does not resolve a fault with the
Nozzle.
Tools/parts:
Ultrasonic Cleaner (not heated)
Microscope (optional)
MEK
Ethanol
Water
Clean dry air (canned air recommended)
CAUTION: Do NOT use a heated ultrasonic bath – damage will result to Nozzle and Nozzle body.
Stage 1:
1. Clean substantial deposits of Ink or other debris with MEK (using a squirt bottle).
2. Place the Nozzle in a small beaker of the proper solvent for your Ink type. Place the beaker in the
ultrasonic bath, lightly floating in water for 3 to 6 minutes.
3. Remove the Nozzle and dry it with clean air.
4. Inspect the interior of the Nozzle using a microscope. If debris remains, continue to Stage 2.
Stage 2:
1. Place the Nozzle in a small beaker of PHETCH (Citronix part number 016-1016-001). Place the
beaker in the ultrasonic bath, lightly floating in water for a maximum of 5 minutes.
CAUTION: Use a clean beaker (free of MEK) for this process. Mixing of solvents and/or water may clog
the Nozzle beyond recovery.
2. Remove the Nozzle and dry it with clean air.
3. Inspect the interior of the Nozzle using a microscope. If debris remains, continue to Stage 3.
Stage 3:
Replace the Nozzle as described in previous procedure.
