A recording apparatus is provided for determining a relative moving speed between a recording head and a recording medium based on application amount information and power information corresponding to power for driving a heating element. In a case of the power amount in a first amount, the moving speed is determined as a first speed in a case where an application amount is equal to a predetermined amount, and the moving speed is determined as a speed higher than the first speed in a case where the application amount is smaller than the predetermined amount. In a case of the power amount in a second amount smaller than the first amount, the moving speed is determined as a speed higher than the first speed in a case where the application amount is equal to the predetermined amount.

In an example implementation, a processor-readable medium stores code representing instructions that when executed by a processor cause the processor to initiate motion of a media web in an inkjet web press, begin printing a print frame based on a start pulse from a metering device, verify that printing the print frame is complete, receive a signal from the metering device that a frame-length of the media web has been measured at the output of the press, and begin printing a new print frame based on the verification and the signal.

Regarding an image forming apparatus for printing an input image and including a print head having a head sensor configured to sense information from the input image printed on a print medium, there is a method of determining a head sensor position parameter in the image forming apparatus. The method includes printing a first swath of the input image on the print medium and determining the head sensor position parameter by performing a sub-method. The sub-method includes capturing, via the head sensor, a target image from the printed first swath, comparing the target image to a reference image for the first swath based upon the input image, and determining the head sensor position parameter based on a relative shift between the target image and the reference image.

A printing control device is for a printing unit that is capable of adjusting a gap g between a recording head and a platen and performs main scanning to move the recording head in the main scanning direction with respect to the print substrate and sub-scanning to move the print substrate in a sub-scanning direction relative to the recording head. The printing control device includes a sub-scanning control unit that controls sub-scanning so that a first sub-scanning distance in a case in which the gap g is a first gap is shorter than a second sub-scanning distance in a case in which the gap g is a second gap broader than the first gap, in the sub scanning which corresponds to pseudo-band printing scheme and which is sub-scanning of a longer distance than a pitch of the nozzles of the nozzle line in the sub-scanning direction.

The control unit is configured to acquire a first current profile based on the reference current when the medium is transported in a first transport speed mode, and to generate a second current profile based on the first current profile.

Disclosed is a recording apparatus for conveying a recording sheet such as a long sheet with high precision without decreasing productivity even if a back tension occurs during conveyance of the recording sheet. The recording apparatus (100) sets a first acceleration period in which the conveying speed is increased up to a first predetermined speed before a leading end of the roll paper (101) reaches a detecting position of the leading end detecting sensor (129) with the roll paper (101) being nipped by the upstream side nip roller (125) and the conveying belt (121). Further, the recording apparatus (100) sets a first constant speed period in which the conveying speed is kept constant at the first predetermined speed before the leading end of the roll paper (101) reaches the detecting position until the leading end of the roll paper (101) is nipped by the downstream side nip roller (126) and the conveying belt (121). Furthermore, the recording apparatus (100) sets a second acceleration period in which the conveying speed is increased up to a second predetermined speed before the recording by the recording head (130) is started after the leading end of the roll paper (101) is nipped by the downstream side nip roller (126) and the conveying belt (121).
