Cleaning printer cartridges with ultrasound – how it works
Who hasn't experienced this: After a long break from printing or after using a third-party ink, the cartridge suddenly dries out. Deposits build up on the print head, degrading the print quality or, in the worst case, rendering the entire print head unusable. Streaks in the print, pale ink application, or no ink at all from the nozzle – these are all classic symptoms. But instead of buying expensive replacement cartridges, the problem can often be solved quickly and inexpensively with an ultrasonic cleaner .
Why ultrasound helps with printer cartridges
Ultrasonic cleaning uses high-frequency sound waves that create millions of tiny bubbles in the cleaning fluid. These bubbles implode and dissolve even stubborn ink residue and deposits on the nozzles – without any mechanical scrubbing. The advantage:
-
Gentle cleaning without damaging the print head
-
Effective solution even for dried ink
-
Fast results after just a few minutes in the water bath
-
Cost-saving as no new cartridge is needed
Step-by-step: Cleaning the printer cartridge in an ultrasonic bath
-
Preparation : Carefully remove the printer cartridge or print head from the device. For permanently installed heads, check whether they are suitable for ultrasonic cleaning.
-
Filling : Fill the ultrasonic cleaner with distilled water. For better results, add cleaning concentrate EM-70 or, for metallic components, Tickopur TR 2 .
-
Positioning : Place the cartridge or print head in the device so that only the bottom with the nozzles is submerged in water. Electrical contacts must not be submerged.
-
Start cleaning : Turn on the device and let it run for 3–5 minutes. Repeat the process if it is heavily soiled.
-
Rinse & Dry : Carefully remove components, rinse with distilled water, and allow to dry completely. Only then reinsert them into the printer.
-
Perform a test print : After installation, start a nozzle test to check the print quality.
Which ultrasonic cleaner is suitable?
-
Emmi-04D : Compact model for private users, ideal for occasional cleaning.
-
Emmi-D21 : With a larger stainless steel tub (2.0 liters) also suitable for more frequent use.
-
Professional models : For printer service stations or repair shops, more powerful devices with heating and timer functions are worthwhile.
Cleaning concentrates for optimal results
-
EM-70 : Specially developed for ink residues, gently removes dried ink.
-
Tickopur TR 2 : For metallic materials in the print head, ideal for thorough deoxidation.
-
EM-080 Universal Cleaner : For light soiling and versatile use.
