Abstract

Disclosed is the use of a high pressure output from a vacuum pump to pressurize a rigid container within which ink is contained in flexible bags. This pressurized ink supply enables the filling of print bar manifolds in thermal ink jet printers. The vacuum pump is an existing pump located in the maintenance system.

FILLING MECHANISM FOR FULL WIDTH ARRAY PRINT BARS (Cont'd)

As shown in the accompanying figure, the high pressure side 12 of a vacuum pump 10 is connected to a plurality of rigid ink supply housings 18, 20, 22, and 24. The low pressure side 14 of the vacuum pump 10 connects to a maintenance carriage 16. Each of the rigid ink supply housings 18, 20, 22, and 24 contains a respective flexible ink bag 38, 36, 34, and 32. The pressure applied to the ink bags 38, 36, 34, and 32 is controlled by the sizing of a respective port 40, 42, 44, and 46 in each of the housings 18, 20, 22, and 24. Alternatively, bleeder fittings (not shown) located upstream from the housings 18, 20, 22, and 24 may be used to apply pressure to the ink bags 38, 36, 34, and 32. However implemented, the desired pressure must be great enough to overcom...
