Abstract: An apparatus comprises a dryer to force air onto a printed media during use to dry the printed media, and an air collector comprising at least one suction opening throughout which, in use, air from the dryer is collected. The apparatus may guide the collected air back to the dryer. The at least one suction opening may be arranged so as to stop the printed media from rising due to pressure differential.

Abstract: A method of determining calibration values for a media advance system of a page wide array printing device is described. A test pattern is printed on a calibration medium which advances along a media axis through the printing device. The test pattern comprises a plurality of test marks. The test pattern is scanned along a scan axis using a sensor and the calibration medium is advanced along the media axis through the printing device. The dimensions of the scanned test marks are analyzed, and calibration values are determined from the analyzed dimensions of the test marks. The scan axis is orthogonal to the media axis.

Abstract: A method for controlling a print device by generating a firing encoder signal from varying one or more characteristics of a reference signal where the one or more characteristics are varied based on at least the position of a print medium at a reference time. The firing encoder signal is used to synchronize firing of at least one print head of the print device after the reference time.

Abstract: An example apparatus is described which comprises a rotary member supported by a bearing. A rotary encoder is registered with respect to the rotary member to rotate therewith and a sensing arrangement is registered with respect to a surface of the bearing. The sensing arrangement is responsive to rotation of the encoder to generate a signal indicative of a rotational characteristic of the rotary member.

Abstract: A fluid ejection device includes first and second nozzles arranged at a pitch. The pitch for example is based on a substrate advance distance associated with a complete turn of a rotating body for advancing a substrate or a substrate advance distance associated with a period of a periodic error function.
