Using The Clean Printhead Button; Manual Printhead Cleaning; Still Experiencing Print Quality Issues - Hasler HJ950C Operating Manual

Using the Clean Printhead Button:

A "Level 1 Maintenance" can be activated by pressing the
"Clean Printhead Button", located on the print engine; as
shown. The wiper roller, in the Service Station, will perform a
quick cleaning of the printhead nozzles.
Tip: The User Maintenance Levels, located under the
Services Tab of the M Series Driver, should be used to do a
more thorough cleaning.

Manual Printhead Cleaning:

NOTE: We recommend the use of disposable gloves for this process.
As a last resort, if running the built-in User Maintenance Levels doesn't help improve print quality; the
printhead cartridge can be removed and cleaned manually.
1. Remove the Printhead Cartridge from the print engine. Refer to Steps 1 through 5 in
the Printhead Cartridge" to remove the printhead.
NOTE: Keep the printhead nozzle area facing down and keep the ink port areas angled back
slightly to help reduce the chance of ink spilling from the ink ports.
2. Clean the printhead nozzles. Once the printhead cartridge is removed; dampen a lint-free cloth (i.e.
Cartridge Wipes, PN 2023-H), with deionized or distilled water. Keep the printhead nozzle area
facing down and gently wipe the printhead nozzle area, from end to end, in one direction and in
one fluid motion. You can repeat this process a few times, but only wipe in one direction.
NOTE: The use of deionized water (reference ASTM D5127-90 Type E-II Electronic Grade
Water) is preferred; however it is acceptable to use distilled water if deionized water is not
available. Do NOT use tap water or paper towels to clean the printhead nozzles. Doing so may
cause damage to the printhead cartridge and possible contamination to the ink system.
WARNING! Be careful not to wet the cartridge contacts during this process. Inserting a printhead
cartridge with wet contacts will result in damage to the printer's electronics. Make sure the
Printhead cartridge contacts are dry before re-installing the printhead.
3. Re-install the Printhead Cartridge. Please refer to the section titled
Cartridge".
