Engine board (printer)
4-1-2 Paper feeding mechanism When a paper feed start signal is received from the engine board of the printer, the paper feed clutch 1 turns on to rotate the pickup roller 2 and feed roller 3, to start the paper feed operation. At this point, multiple paper feeding is prevented by the retard pulley 4. The paper feed motor 5 then conveys the paper through the conveying roller 6 and feed pulley 7 into the printer by rotating the conveying roller 6. The paper feed sensor 8 detects paper jams.

4-2-2 Operation of circuit board (1) Paper feeder board The paper feeder board serially communicates with the engine board of the printer and the paper feeder board of the lower paper feeder to exchange control signals. Upon reception of a paper feed start signal from the engine board of the printer, CPU IC3 controls the paper feed operation by operating the paper feed motor and paper feed clutch. The motor drive circuit consists mainly of motor driver IC5. It drives the paper feed motor based on the control signals (PFM, PWM) from CPU IC3. The reset circuit consists mainly of reset IC1. It monitors the 5 V DC supply voltage. When the power is turned on or when the power supply becomes low, it outputs a RESET signal to CPU IC3, to prevent system malfunction or runaway.

7-1 General guidelines
The paper feeder may not be used to print on paper not satisfying the requirements below. Also, special types of print media such as overhead projection (OHP) film, envelopes, adhesive backed labels, and paper containing watermarks must not be used with printing with the paper feeder. These types can result in jams, misfeeds, and paper waste, and in extreme cases can damage the paper feeder. NOTE Kyocera mita assumes no liability for problems that occur when paper not satisfying these requirements is used with the paper feeder.
Selection of the right paper is important. The wrong paper can result in jams, misfeeds, curl, poor print quality, and paper waste, and in extreme cases can damage the paper feeder and the printer. The guidelines given below will increase the productivity of your office by ensuring efficient, trouble-free printing and reducing wear and tear on the paper feeder and the printer. 7-1-1 Paper availability Most types of paper are compatible with a variety of machines. Paper intended for xerographic copiers can also be used with the paper feeder and the printer. There are three general grades of paper: economy, standard, and premium. The most significant difference between grades is the ease with which they pass through the printer. This is affected by the smoothness, size, and moisture content of the paper, and the way in which the paper is cut. The higher the grade of paper you use, the less risk there will be of paper jam and other problems, and the higher the level of quality your printed output will reflect. Differences between paper from different suppliers can also affect the paper feeder's performance. A high-quality printer cannot produce high-quality results when the wrong paper is used. Lowpriced paper is not economical in the long run if causes printing problems. Paper in each grade is available in a range of basic weights (defined later). The traditional standard weights are 16, 20, and 28 pounds (60 g/m2 to 105 g/m2).
PF-60
7-3
7-1-2 Selecting the right paper Printer printing is a process involving laser light, electrostatic discharge, toner, and heat. In addition, as the paper passes through the printer it undergoes considerable sliding, bending, and twisting motions. A high-quality printing paper matching the requirements withstands all these stresses, enabling the paper feeder and the printer to turn out clean, crisp printed copy consistently. Remember that all paper is not the same. Some of the factors to consider when selecting paper is as following in the next section.
PF-60
7-4
7-2 Paper specifications
The following table summarizes the basic paper specifications that should be applied to the paper used with the paper feeder. Details are given following the table. Table 7-2-1 Specifications Item Weight Thickness Dimensional accuracy Squareness Moisture content Direction of grain Pulp content Specification 60 to 105 g/m2 (16 to 28 lbs./ream) 0.086 to 0.110 mm (3.4 to 4.3 mils) ±0.7 mm (±0.0276 inches) 90° ±0.2° 4 to 6 % Long grain 80 % or more
7-2-1 Points of consideration The following section provides general information which should be considered when selecting paper for using with the paper feeder. (1) Condition of the paper Avoid using paper that is bent at edges, curled, dirty, torn, or contaminated with lint, clay, or paper shreds. Used of paper in these conditions can lead to illegible printing, misfeeding, and paper jams, and can shorten the life of the paper feeder and the printer. In particular, avoid using paper with a surface coating or other surface treatment. The paper should have as smooth and even a surface as possible. (2) Composition Do not use paper that has been coated or surface-treated and contains plastic or carbon. The heat of fusing can cause such paper to give off harmful fumes. Bond paper should contain at least 80% pulp. Not more than 20% of the total paper content should consist of cotton or other fibers.
PF-60
7-5
(3) Paper size The paper feeder is usable with the paper sizes as tabled below. Table 7-2-2 Paper size Paper size ISO A4 JIS B5 ISO A5 Letter Legal Dimension 210 × 297 mm 182 × 257 mm 148 × 210 mm 8-1/2 × 11 inches 8-1/2 × 14 inches
(4) Smoothness The paper should have a smooth, uncoated surface. Paper with a rough or sandy surface can cause voids in the printed output. Paper that is too smooth, however, can cause multiple feeding and fogging problems. (Fogging is a gray background effect.) (5) Basis weight Paper that is too light or too heavy can cause misfeeding, jams, and premature wear of the paper feeder and the printer. Uneven paper weight can cause multiple feeds, print defects, poor toner fusing, blurring, and other print quality problems. The proper weight is 60 to 105 g/m2 (16 to 28 Ibs/ ream). (6) Thickness (Caliper) Thick paper is referred to as high-caliper paper and thin paper as low-caliper paper. The paper used with the paper feeder should be neither extremely thick nor extremely thin. If you are having problems with paper jams, multiple feeds, and faint printing, the paper may be too thin. If you are having problems with paper jams, and blurred printing the paper may be too thick. The proper thickness is 0.086 to 0.110 mm (3.4 to 4.3 mils). (7) Moisture content Moisture content is defined as the percent ratio of moisture to the dry mass of the paper. Moisture can affect the paper's appearance, feedability, curl, electrostatic properties, and toner fusing characteristics. The moisture content of the paper varies with the relative humidity in the room. When the relative humidity is high and the paper absorbs moisture, the paper edges expand, becoming wavy is appearance. When the relative humidity is low and paper loses moisture, the edges shrink and tighten, and print contrast may suffer.
PF-60
7-6
Wavy or tight edges can cause misfeeding and alignment anomalies. The moisture content of the paper should be 4 % to 6 %. To ensure the proper moisture content it is important to store the paper in a controlled environment. Some tips on moisture control are: Store paper in a cool, dry location. Keep the paper in its wrapping as long as possible. Rewrap paper that is not in use. Store paper in its original carton. Place a pallet etc. under the carton to separate it from the floor. After removing paper from storage, let it stand in the same room as the printer for 48 hours before use. Avoid leaving paper where it is exposed to head, sunlight, or damp. (8) Paper grain When paper is manufactured, it is cut into sheets with the gain running parallel to the length (long grain) of parallel to width (short grain). Short grain paper can cause feeding problems in the paper feeder and the printer. All paper used in the paper feeder and the printer should be long grain. 7-2-2 Other paper properties (1) Porosity Refers to the density of the paper structure; that is, to how openly or compactly the fibers are bonded. (2) Stiffness Limp paper can buckle inside the paper feeder and the printer, while paper that is too stiff may bind. Either way the result is a paper jam. (3) Curl Most paper has a natural tendency to curl in one direction. The paper should be loaded so that the natural curl is downward, to counteract the upward curl imparted by the printer. Printed sheets will then come out flat. Most paper also has a top and bottom surface. Loading instructions are usually given on the paper package.
PF-60
7-7
(4) Electrostatic properties During the printing process the paper is electrostatically charged to attract the toner. The paper must be able to release this charge so that printed sheets do not cling together in the output tray. (5) Whiteness The contrast of the printed page depends on the whiteness of the paper. Whiter paper provides a sharper, brighter appearance. (6) Quality control Uneven sheet size, corners that are not square, ragged edges, welded (uncut) sheets, and crushed edged and corners can cause the paper feeder and the printer and the printer to malfunction in various ways. A quality paper supplier should take considerable care to ensure that these problems do not occur. (7) Packaging Paper should be packed in a sturdy carton to protect it from damage during transport. Quality paper obtained from a reputable supplier is usually properly packaged. 7-2-3 Special paper The following types of special paper can be used: Colored paper Preprinted paper Use paper that is sold specifically for use with copiers (heat-fusing type). Since the composition and quality of special paper very considerably, special paper is more likely than white bond paper to give trouble during printing. No liability will be assumed if moisture etc. given off in printing on special paper causes harm to the machine or operator. NOTE Before purchasing any type of special paper, test a sample on the paper feeder and the printer and check that printing quality is satisfactory.
Specifications for each type of special paper are given on next page.
PF-60
7-8
(1) Colored paper Colored paper should satisfy the same conditions as white bond paper, listed in used in the paper must be able to withstand the heat of fusing during the printing process (up to 200 °C or 392 °F). (2) Preprinted paper Preprinted paper should have a bond paper base. The preprinted ink must be able to withstand the heat of fusing during the printing process, and must not be affected by silicone oil. Do not use paper with any kind of surface treatment, such as the type of paper commonly used for calendars.
