Handling Paper
This chapter explains the following topics: General Guidelines Special Paper Paper Type How to Load Paper

1.2 Paper Specifications

The following table summarizes the basic paper specifications. Details are given on the following pages. Item Weight Specification Cassette: 60 to 105 g/m2 (16 to 28 lb/ream) MP tray: 60 to 200 g/m2 (16 to 53 lb/ream) 0.086 to 0.110 mm (3.4 to 4.3 mils) 0.7 mm (0.0276 inches) 90 0.to 6 % Long grain 80 % or more

1. General Guidelines

The printer is designed to print on high-quality copier bond paper (the kind used in ordinary dry copier machines), but it can also accept a variety of other types of paper within the limits specified below. NOTE The manufacturer assumes no liability for problems that occur when paper not satisfying these requirements is used. Selection of the right paper is important. Using the wrong paper can result in paper jams, misfeeding, curling, poor print quality, and paper waste, and in extreme cases can damage 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 printer.
Thickness Dimensional accuracy Squareness of corners Moisture content Direction of grain Pulp content Table 2-1
Minimum and maximum paper sizes The minimum and maximum paper sizes are as follows. For non standard paper such as cut-sheet, the MP (multi-purpose) tray must be used.

Minimum Paper Size

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 printer.

432 mm 17 inches

Paper Cassette

MP Tray

148 mm 5-13/16 inches 450 mm 18 inches

210 mm 8-1/4 inches

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 jams 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 printers performance. A high-quality printer cannot produce high-quality results when the wrong paper is used. Low-priced paper is not economical in the long run if it causes printing problems. Paper in each grade is available in a range of basis weights (defined later). The traditional standard weights are 16, 20, and 28 pounds (60 to 105 g/m2).

88 mm 3-7/16 inches

148 mm 5-13/16 inches

297 mm 11-11/16 inches

Chapter 2 Handling Paper

1.3 Selecting the Right Paper
Laser 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 printers requirements withstands all these stresses, enabling the printer to turn out clean, crisp printed copies consistently. Remember that all paper is not the same. Some of the factors to consider when selecting paper for the printer are as follows: Condition of the Paper Avoid using paper that is bent at the edges, curled, dirty, torn, embossed, or contaminated with lint, clay, or paper shreds. Use of paper in these conditions can lead to illegible printing, misfeeding, and paper jams, and can shorten the life of 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. 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. Paper Size Cassettes and an MP tray are available for the paper sizes listed in the table below. The dimensional tolerances are 0.7 mm (0.0276 inches) for the length and width. The angle at the corners must be 90 0.2.

1. Parallel Interface

1.1 Parallel Interface Communication Modes
The printer features fast data transmission with the parallel interface. The parallel interface mode can be activated from the operator panel. See Changing Parallel Interface Modes on page 3-19. NOTE Use a parallel printer cable that complies with the IEEE1284 standard. Nibble (high) [default] High speed data communication is used in compliance with the IEEE1284 standard. Ordinarily, you should leave this setting unchanged. Auto The printer automatically changes its communication mode to the one the host computer is currently using. Normal The printer uses the standard communication method prescribed for Centronics interfaces. High-speed This mode enables faster data transmission between the printer and the host computer. (Select this mode if printing problems occur when the printer is connected to a workstation.)

1.2 Interface Signals

The pins of the parallel interface connector carry the signals listed in the table in Parallel Connector Pin Assignment. As-
Appendix B Host Computer Interface
[ ]: Signal names in the Auto mode and Nibble (high) mode (IEEE1284). In the Auto mode and Nibble (high) mode, these signals are bidirectional.

2. USB Interface

This printer supports the Hi-Speed USB 2.0. USB (Universal Serial Bus) interface specifications and interface signals are as follows.
Detailed descriptions of the signals follow. Strobe* [nStrobe] (Pin 1) A negative-going Strobe* pulse causes the printer to read and latch the data on the Data 0 [1] to Data 7 [8] signal lines. Data 0 [1] to Data 7 [8] (Pins 2 to 9) These eight signals form the data byte sent from the host computer to the printer. Data 7 [8] is the most significant bit. Acknowledge* [nAck] (Pin 10) This negative-going pulse acknowledges the previous character received by the printer. Busy [Busy] (Pin 11) This signal is high when the printer is busy and low when it is able to accept more data. Paper Empty [PError] (Pin 12) This signal goes high when the printer has received a print job and run out of paper. Online [Select] (Pin 13) This signal is high when the printer is online and low when the printer is offline. It goes low when the GO key is pressed to set the printer offline. +5 V DC (Pin 18) This line is connected to the printers +5 V DC line (+5 V 0.5 V, maximum 400 mA [Serial and Parallel total], fused). Error* [nFault] (Pin 32) When the high-speed parallel line control is on (FRPO O2=2), this line returns error status. Power Ready (Pin 35) This signal is high when the printer is turned on. NOTE The Paper Empty, Online, and Error signals are not used unless enabled by the FRPO command (O2 parameter).
