Title:
INK JET RECORDING DEVICE
Document Type and Number:
WIPO Patent Application WO/2007/080806
Kind Code:
A1
Abstract:
An ink jet recording device uses a plurality of line-type ink jet recording heads for
one-color ink and divides image data so as to correspond to the plurality of recording
heads to form an image. Even if one of the recording heads has a nozzle of defective
discharge, it is possible to perform a complementary recording operation with
a simple configuration without significantly lowering the recording speed.
When one (102) of the recording heads has a nozzle of defective ink discharge, the
recording operation to be performed by the nozzle is complemented by a corresponding nozzle
of other recording head (such as an auxiliary recording head (114)). Here, the
same divided image data is supplied to the one recording head and the other recording
head. For the one recording head, recording operation is disabled only at the
timing when the nozzle of defective discharge is driven and for the other recording
head, recording operation is enabled only at the timing when the corresponding
nozzle is driven.
