Abstract
A method and apparatus prevents banding defects caused by drop mass variations in an ink jet printer. The ink jet printer uses different pre-pulse sequences for drop ejection depending on print head temperature. Each of the different pre-pulse sequences is associated with a corresponding temperature range. Boundaries between adjacent temperature ranges are separated by critical temperatures. A determination is made as to whether a change in the print head temperature constitutes, or is part of, a temperature change that exceeds a predetermined threshold change amount, prior to determining whether to change the pre-pulse sequence.
