Abstract:
1. A liquid ejecting apparatus comprising: a sheet transfer mechanism including a conveyor belt for feeding a recording medium, and a driving device for driving the conveyor belt, the conveyor belt having a sheet support surface on which the recording medium is placed; at least one liquid-ejecting head configured to eject a liquid onto the recording medium being fed by the conveyor belt; a medium attraction portion disposed in opposition to a surface of the conveyor belt, which surface is opposite to the sheet support surface, and having a first electrode and a second electrode which are spaced apart from each other in a plane parallel to the sheet support surface and to which respective different electric potentials are applied to generate an attraction force for attracting the recording medium to the sheet support surface of the conveyor belt; a memory portion configured to store image data relating to an image to be printed on the recording medium; a variation amount estimating portion configured to estimate, during printing of the image on the recording medium and on the basis of the image data stored in the memory portion, an amount of variation of a volume of the liquid to be deposited in a subject area of the recording medium which includes a gap-opposition area opposed to a gap formed between the first and second electrodes; and a sheet feeding control portion configured to control the driving device, and wherein the sheet feeding control portion changes a drive force of the driving device for driving the conveyor belt, so as to restrict a variation of a feeding speed of the recording medium by the conveyor belt, during an excessive variation period during which the amount of variation of the volume of the liquid estimated by the variation amount estimating portion exceeds a predetermined upper limit.
