Cleaning Cartridge Nozzles - Solvent Inks
During idle-time nozzles can dehydrate and clog. During printing process ink spray, paper fibers, and dust can
build up on the Nozzle Plate. Nozzle dehydration and particle build-up will eventually block nozzles and
degrade print quality. Maintain good print quality by keeping Printheads clean.
CAUTION : Wear nitrile protective gloves when cleaning ink cartridges.
1. Use a DRY, lint free, cloth to clean Solvent Ink cartridge nozzles.
2. Wipe slowly across the long-axis of the nozzles, with Nozzle Plate
facing down ( as shown ).
Wipe in one direction only.
DO NOT apply excessive force, as this could scratch nozzle area
causing misdirected nozzle firing and fuzzy print.
3. Repeat as needed.
TIP: If cleaning using a dry, lint free, cloth does not improve print
quality, you can attempt to clean Solvent Ink cartridge nozzles using
Isopropyl Alcohol (70% or higher) on a lint-free cloth. This should only
be done as a last resort, on rare occasions. Do NOT use liquids (other than Isopropyl Alcohol) to clean
Solvent Ink cartridge nozzles.
WARNING: Never Shake or Bang Inkjet Cartridges. This can cause air bubbles and or foam to form, within
cartridge bladder, which can result in poor print quality and or Ink Cartridge damage.
Cleaning Storage Clip Pad – Solvent Inks
Before installing an Ink Cartridge into its “Storage Clip”, please be sure to clean the “Pad” within the Cartridge
Storage Clip. If not, Cartridge nozzles may be clogged/damaged by ink/debris on Pad.
When using Solvent Ink Cartridges, “Pad” should be cleaned using Isopropyl Alcohol (70% or higher) and a lint-
free cloth.
NOTE: It is best to clean the Pad at the time the cartridge is removed from the Storage Clip.
