|T1−T2|/T1<0.15   Expression (1)
where T1 is a temperature [° C.] of a paper end of the paper at the position of the printing part, and T2 is a temperature [° C.] of the paper end of the paper when the paper is transferred from the sheet feeder to the conveyance cylinder.

Printing onto a print medium

In some examples, a first heating stage heats a print medium to a first temperature in a printing region when printing latex ink on the print medium, and a curing heating stage heats, in a curing zone, the print medium to a curing temperature greater than the first temperature to cure the latex ink on the print medium. A cooling stage located between the first and curing heating stages cools the print medium by directing a first part of airflow from the cooling stage to a printing zone, the cooling performed after the print medium has been heated by the first heating stage and prior to heating of the print medium by the curing heating stage. A second part of the airflow is directed from the cooling stage to the curing zone.

Fan assembly for a cut sheet inkjet printer, cut sheet inkjet printer and method for operating a fan assembly for a cut sheet inkjet printer

An air fan assembly includes a suction box including a wall having an open area distributed across the wall. The suction box is configured to contain an underpressure on an inner side of the wall, so as to cause a cut sheet to adhere to a perforated transport belt. An impingement unit is configured to expel air supplied thereto towards the perforated transport belt. An air fan is arranged to create and maintain the underpressure in the suction box and to supply the air to be expelled by the impingement unit via an air outlet of the suction box. A first valve is arranged upstream of the air fan for conditionally admitting an additional air flow into the suction box. An inkjet printer and a method of operating the air fan assembly include the air fan assembly.
