Printhead Maintenance, Procedures | HP 98SI, 72SI specs

Printhead Maintenance

The printer uses air pressure to both fill and evacuate ink and cleaning solvent from the printheads. The following functions are available from the menu at Maintenance - Printhead

Procedures:

◆Cleaning Solvent Soak — empties the printheads of all ink, fills all heads with cleaning solvent, and prompts you to cap the printheads. Reverses this process after the printheads have soaked (for example, overnight). See page 5-10 for instructions.

◆Prep for Storage/Shipping — empties the printheads of all ink, fills all heads with cleaning solvent, then empties the printheads. See “Extended Power Down and Restart” on page 5-21 for instructions.

◆Load Ink In All Heads — when installing ink for the first time, or when restarting the printer after an extended power down period, this function fills the empty printheads with cleaning solvent, empties the printheads, and fills the heads with ink. See “Extended Power Down and Restart” on page 5-21 for instructions.

◆Fill Heads with Solvent — fills the printheads with cleaning solvent, one color set of four printheads at a time. Should only be done with empty printheads.

◆Fill Heads with Ink — fills the printheads with ink, one color at a time. Should only be done with empty printheads.

◆Empty Heads (Fill With Air) — empties all printheads by purging the ink and cleaning solvent with air.
