Title: Printer
Inventor: YOSHIDA MINORU
IPC: G03G15/01
Filed: 1995-12-21
Abstract: PROBLEM TO BE SOLVED: To eliminate the interference of a suction means with a transfer area so as to perform satisfactory printing by providing a control means for making a suction bias, applied by a suction means, floating potential immediately before paper reaches a transfer means. SOLUTION: Paper aligned by an aligning roller 12 is impressed with a suction bias by a suction roller 10 and sucked to a transfer belt 5. The paper is conveyed by the travel of the transfer belt 5 and fed in between a photoconductor 1 and a transfer roller 6. A control means 21 is connected to a voltage applying means 16 for applying the suction bias to the suction roller 10, and the control means 21 controls the application of the suction bias to the suction roller 10. It is so controlled that the suction bias becomes floating potential immediately before the paper reaches a transfer area. The timing of making the suction bias floating potential is based on aligning timing. Even in the state of the paper becoming conductive in high temperature and high humidity environment or the like, there is therefore no generation of a transfer failure influenced by the suction bias.

After the modulation with comparison fluids R1 and R2 by frequencies F1 and F2 using fluid modulation means V1 and V2, the fluid S1 and S2 converted are supplied to a detector D. A signal O outputted from the detector D is separated into signal components O1 and O2 with the modulation frequencies F1 and F2 relative to the fluids F1 and F2 by a signal processing means B and a signal processing is performed to obtain the results of measuring the first and third components. This enables measurement of a single concentration of the second component (non-methane HC) from a difference between the results of measuring both the concentrations.
