Abstract: A serial recording apparatus is disposed for recording onto a recording medium while moving relatively a recording head with a plurality of recording elements arranged and the recording medium in a main scan direction and a sub scan direction which are orthogonal to each other. The apparatus includes a receiving unit for receiving a recording signal, and a recording controller means for enabling the recording head to record in one-way or two-way movement depending on the information of pixel density which the receiving unit receives.

Abstract: There is disclosed a color facsimile apparatus capable of communication of a color image, utilizing plural colorants in the printing unit, wherein, when one of the colorants runs out in the printing unit, such colorant is replaced by another colorant and the image printout is conducted with a varied resolution, for example with a reduced image size, in order that the operator can immediately recognize the absence of the colorant.

Abstract: A recording apparatus performing image recording on a recording medium by driving a recording head having a plurality of recording elements. The recording apparatus has a storing device and a driving device. The storing device prestores a drive condition for each respective one of blocks which are formed by dividing the recording elements into a plurality of groups. The driving device simultaneously drives the recording elements in the same block according to the drive condition read from the recording device. In a preferred embodiment, the recording apparatus has recording portions each of which prerecords a pattern representing an index of energy to be fed to the electrothermal transducers of each respective one of the blocks, and a read device for reading out the index of energy from the recording portion via driver circuit.
