Page 44 Ch-C1 Training New Features - 3  Improvement for the Scratch Mark Issue Items Description CH-C1 CH-C1 Office Fusing Belt CH-C1 Pro has a new fusing belt smoothing roller to counter the scratch mark issue. This Smoothing roller gives pressure and rubs against the Roller belt surface to smoothen the rough parts caused by the paper edges.
Page 45 Ch-C1 Training New Features - 4  Printing Quality of Textured Paper Items Description CH-C1 CH-C1 Office AC transfer In order to improve printing quality on textured media, CH-C1 Pro uses AC transfer. This can increase toner transfer to the media by generating better adherence between toner and ITB.
Page 46 Description CH-C1 CH-C1 Office Easy Jam The front cover of the CH-C1 series is like a drawer and operators can directly access the inner unit. Paper Same as the Aries and Taurus, the CH-C1 Pro also has a Paper Library to offer...
Page 47 Ch-C1 Training New Chemical Toner Overview  This new toner allows the following improvements:  Improved color reproduction  Lower toner pile height  Energy saving due to low melting point Slide 47 No additional notes...
Page 48 Ch-C1 Training New Chemical Toner Improved Color Reproduction Ch-C1 series Previous Models  The color gamut for the CH-C1 series is about 10% larger than for previous models of this type. Slide 48 No additional notes...
Page 49 10% less than on plain paper. This prevents excessively glossy output on coated paper and produces suitable glossiness for each paper type.  The toner pile height for the CH-C1 series will be lower than current products, and roughness on printed paper will decrease.
Page 50 Ch-C1 Training New Chemical Toner Energy Saving  The melting point of this toner is about 20 degrees lower than for the Aries and Taurus. Slide 50 No additional notes...
Page 51 Ch-C1 Training VCSEL Laser Technology Overview  The Taurus uses this system also. However, the Taurus has one VCSEL unit for each color and the Ch-C1 only has two VCSEL units.  One VCSEL unit handles K and C, and the other handles Y and M.
Page 52 Ch-C1 Training VCSEL Laser Technology Magnification Correction  In duplex mode, some paper may shrink or enlarge after it goes through the fusing unit, and this change in paper size may result in inaccurate registration between the front and back pages. VCSEL can correct for this. ...
Page 53 Ch-C1 Training VCSEL Laser Technology Bow Skew Correction Main Scan Direction Correction  The two-dimensional VCSEL array of laser diodes allows precise control of image reproduction.  If the MUSIC sensors detect that lines across the image are bent as shown above, the machine can adjust the image signals that are sent to each of the 40 lasers.
Page 54 Ch-C1 Training VCSEL Laser Technology Optical Waveform Correction Without Correction With Correction  VCSEL technology ensures that a constant current is applied to the laser diode.  The effects of this are clear when printing thin diagonal lines. Slide 54 No additional notes...
Page 55 Ch-C1 Training Improved Process Control DEMS  One of the reasons for banding is variations in the distance between the drum and the development roller.  When the gap between development roller and OPC drum changes, inconsistencies in color will occur due to changes in the amount of toner adhering to the latent image ...
Page 56 Ch-C1 Training Improved Process Control Active Toner Supply Control  The Pro version has this feature, similar to the Taurus.  This technology analyzes the data file being printed, and information from the TD sensor. Then, the precise amount of toner is supplied to the development unit at the required time, in order to keep the toner density in the development consistent.
Page 57 Ch-C1 Training Improved Process Control Mechanical Improvements  Small Gap between Drum and Development Roller  In both Pro and Office models, the gap between the drum and development roller is greatly reduced compared with the Taurus.  This means that the gap between the two components is more stable, which means that banding is reduced.
Page 58 Ch-C1 Training Changes to the ITB CH-C1 Taurus/V-C3 Toner High resistance layer  In the Taurus and V-C3, the paper transfer roller (PTR) has a resistive layer on the surface. In the Ch-C1 (Pro and Office), this layer has been moved to the ITB.
Page 59 Ch-C1 Training Changes to the Fusing Unit Fusing Belt Smoothing Roller - 1  When continuously feeding paper with rough edges, the surface of the fusing belt may become damaged. This damage may cause scratches on the following prints, especially if the paper is wider than the paper that had the rough edges.
Page 60 Ch-C1 Training Changes to the Fusing Unit Fusing Belt Smoothing Roller - 2  The fusing belt smoothing roller presses and rubs against the belt surface to smoothen the rough part caused by the paper edges.  With this technology, customers don’t need to use several fusing units for different types of paper.
Page 61 Ch-C1 Training Changes to the Fusing Unit Improved Cleaning Web  The Ch-C1 Pro has the same cleaning web as the Taurus.  In addition, there is a web separation mechanism.  The pressure roller rotates in reverse to move jammed paper back if a paper jam occurs in the fusing unit.
Page 62 Ch-C1 Training Changes to the Fusing Unit Roller Diameter  In both the Pro and Office versions, the diameters of the fusing and pressure rollers are reduced to 50 mm, to improve separation of paper from the fusing roller (especially for thin paper).
Page 63 Ch-C1 Training Support for Textured Media AC Transfer Current Indentation in the Paper  In the Ch-C1 Pro, AC is used for the transfer current. This transfers more toner to textured media and ensures that it adheres better to this type of media. ...
Page 64 Ch-C1 Training Support for Textured Media Elastic Fusing Belt  In the Ch-C1 Pro, the fusing belt has a thicker elastic layer to reach the toner on the indented regions of textured media. Fusing Roller Current Fusing Belt New Elastic Fusing Belt Base Material Fusing Belt Base Material...
Page 65 Ch-C1 Training Support for Coated Media Hot Rollers  In the office environment, most applications are printed on plain paper. But customers in the production printing market use more coated paper.  To meet these requirements, CH-C1 Pro uses a solid hot roller (same as the Taurus-C1).
Page 66 Ch-C1 Training Support for Envelopes Reduced Nip Width  When an envelope goes through the fusing unit, wrinkles may appear due to the thickness of the envelope.  In the CH-C1 Pro, the fusing nip width and pressure is automatically reduced when printing on envelopes in order to reduce wrinkles.
Page 67 Ch-C1 Training Paper Thickness Detection  If the wrong paper weight setting is used, there may be a jam, insufficient fusing, or even damage to the machine.  Both the Office and Pro versions have a paper thickness detector. If the paper being fed does not match the selected paper type (within a certain tolerance), paper feed is stopped.
Page 68 Ch-C1 Training Fewer Paper Jams Heating Roller Heating Roller Roller Roller Reverse Point Reverse Point Ch-C1 V-C3  The reverse feed path has fewer bends in it compared to the V-C3. Jams should be reduced by 25% because of this. Slide 68 No additional notes...
