A printhead (1) for a continuous ink jet printer, the printer having an ink channel (22, 32, 33) has a nozzle (4, 34) at one end of the ink channel (22, 32). An oscillator (11, 38) is disposed to cause ejection of ink in the channel (22, 32, 33) through the nozzle (4, 34) in use. Means (14, 15, 35, 36) for closing off the nozzle (4, 34) from the channel (22, 32) are provided to prevent seepage of ink therethrough during periods of non-printing, which prevents agglomerations of ink residues forming around the nozzle exit. |
