Inkjet spittoon

An inkjet spittoon is a component in electronic inkjet printers. Inkjet printers commonly experience a problem of drying out which blocks the flow of ink. To restore flow, it is necessary to clean the inkjet head by spraying excess ink through all the jets to reapply moisture and unblock the adjacent clogged jets. The excess ink used for cleaning needs to be collected somewhere to avoid creating a mess below the printer, so inkjet printers have a "spittoon" hidden inside to collect this ink.
