1 Overview
C911/C931/C941/Pro9541WT is a tandem type LED electrophotographic A3Nobi color page printer
having four or five tandemly arranged color image drum cartridges in it.
C911/C931 : 4 color (YMCK）
C941 : 5 color (YMCK+Spot Color : White or Clear)
Pro9541WT : 5 color (YMCK+White)
The printer converts single-color images extracted from original computer text and graphics images
into optical pulses to write them on the surfaces of its optical drums. Dry toner selectively adheres on
the surfaces of image drums. Thus toner image forms on it. The toner images on the drum are
transferred to paper for printing.And toner image on paper is fused by the fuser in printer.
The light sources of C911/C931/C941/Pro9541WT are light-emitting diode (LED) arrays.
1.1 Scope of Application
This specification applies to the C911/C931/C941/Pro9541WT LED A3Nobi color page printers (PDL
type) aimed at world-wide sales markets.
1.2 Use for

1.3 Description
Definitions of terms
(1) Control Unit (PUCU)
The control unit (PUCU) of C911/C931/C941/Pro9541WT, receives and analyzes PS/PCL
commands sent from host computers to draw images. Rasterized images are sent to
process control part and printed. Also controls input and output through an operation panel.
Notices, such as instructionsand warnings are issued to the operation panel and
higher-level host computers according to printer’s operation status information provided by
PUCU. The process control part controls the printing operations performed by the
electrophotographic process of the printer. The PUCU performs the control of the entire
functions of the printer, such as issuing the printer’s internal timing signals to monitor the
printer’s paper path status to print the images.
(2) Print Engine
In C911/C931/C941/Pro9541WT, the parts controlled by the PUCU, mechanism part, image
producing part and various sensors.
(3) PPM (Pages per Minute)
PPM is a measure of the print speed. Expressed in the number of pages a printer can print
in one minute.
(4) SEF (Short Edge Feed) and LEF (Long Edge Feed)
Feeds paper lengthwise and sideways, respectively.
Functional Overview
(1) High-speed Color Image Printing
C911/C931/C941/Pro9541WT adopt a tandem printing system that uses four or five image
drum cartridges placed in series with one another. With the system, the printer can print
monochrome and color images at superfast speeds.

degraded in print quality, with optical densities of K1.5/YMC1.4 or less in each elementary
color(YMC)and 0.26 or more in white. Referto 2.1.6 for the area coverages.
When printing with coverage of 240% or more including 300% process black and white, PQ
depends on the characteristics of the medium to be used.
(3) Exposure System
The exposure system of C911/C931/C941/Pro9541WT consists of four or five LED array
heads that are assembled into one piece each.
(4) Resolutions
1200 x 1200 dpi, 600 x 600 dpi, and 1200 x 600 dpi x 4bit
(5) Continuous Print Speeds (Engine Performance)
C911/C931/C941/Pro9541WT operates at a normal speed of 239mm per second, when it
prints on plain paper of up to 64 g/m2plain paper. The printer can perform one-sided printing,
and two-sided printing using its duplex unit, almost at the following continuous speeds (the
continuous speeds in the one-sided printing, and those in the two-sided printing, are
expressed in per-minute pages printed and in pages printed, respectively).
