摘要:
A paper conditioner (100) to control image dependent curl in a copier/printer includes a reservoir for storing a quantity of liquid, a pair of rolls (102,104;103,105) in contact with one another so as to define a nip (106;107), and a metering roll (108;109) associated with the reservoir and one of the pair of rolls. The metering roll forms a nip with one of the pair of rolls to direct a controlled flow of liquid from the reservoir to the nip area. Seals (140) located at opposed ends of the metering roll (109) and the roll (103) with which it forms a nip prevent the flow of excess liquid from the ends of the metering roll.
摘要:
A paper conditioner (100) to control image dependent curl which uses one or more counterrotating transfer rollers (102, 103) which are initially spaced from their respective back-up rollers (104, 105) in the intercopy gap, and which come together as the lead edge enters the nip area, and separates when the trail edge is about to pass. This permits the rollers to have a less demanding runout tolerance by bringing the rollers together when the sheet is in the nip, and then articulating the rollers apart in the intercopy gap.
