Title:
ADJUSTMENT METHOD FOR FLUID EJECTION ENERGY AND IMAGE FORMING DEVICE FOR EMBODIMENT OF THE METHOD
Document Type and Number:
Japanese Patent JP2005199719
Kind Code:
A
Abstract:

To adjust a fluid ejection energy to yield fluid drop masses having a consistent ratio.

The adjustment method includes steps 402 and 404 for determining a plurality of calibration factors for a fluid ejection mechanism capable of ejecting a plurality of differently colored fluids and a step 410 for adjusting the energy used to eject fluid for each of at least one of the plurality of fluid colors from the plurality of calibration factors so that fluid drop ejections of the fluid colors yield fluid drop masses having a consistent ratio.
