Page 42: Paper Delivery Choices
Chapter 4 Paper With the GQ-3500 you can print on many different sizes and types of paper. The printer feeds most types automatically from the paper tray, while special ones -such as envelopes, labels, and overhead projector transparencies - should be fed individually for greater control.
Page 43: Types Of Paper
16- to 34-pound paper. Special paper -You can use colored or three-hole punched paper in the GQ-3500 as long as it meets the weight limits given above. Labels - Labels designed for plain paper copiers can be used in the GQ-3500.
Page 44: Considerations In Selecting Paper
Considerations in Selecting Paper The paper that you use with your GQ-3500 affects the quality of your printed output. The printed image is made up of many tiny dots of toner that are transferred to the paper. If the paper is rough, the edges of the letters become ragged because some of the dots fall into indentations on the paper, while others fall on the ridges.
Page 45: Choosing A Standard Paper Size
Hand-feeding special papers or envelopes is easy with the GQ-3500. You do not have to remove the paper in the paper tray; just follow these steps: Dimensions 8-1Px 11”...
Page 46: Clearing Paper Jams
Clearing Paper Jams Clearing paper jams is easy. There are three types of paper jams, and the GQ-3500 lets you know which kind is occurring by displaying a special code (J0, J1, or J2) on the status indicator. Pages 5-4 through 5-7 tell you how to clear the jams.

If this happens, write down the error code number, turn off the power, and contact a qualified service representative. 1: printer controller error GQ-3500 detects an error in its controller unit or its system memory, the status indicator displays F I alternating with a two-digit error code number.
Page 62: Corrective Or Preventive Maintenance
Corrective or Preventive Maintenance Because the GQ-3500’s status messages advise you when to replace supplies and consumable parts, little additional preventive maintenance is required. If the printing quality should decline, however, it may help to clean the transfer charger wire. Do this whenever you replace to maintain maximum printing quality.
Page 63 Examine the test print, distinct. If it is, place the GQ-3500 in its normal printing mode by pressing the ON LINE in other ways, replace the drum cartridge as described in Maintenance section of this chapter.
Page 64: Software Control Of Printer Features
Chapter 6 Software Control of Printer Features In Chapter 3 you learned how to select many of the GQ-3500’s functions from the control panel. Many more functions are available through the use of software commands. You can send software codes to the printer by writing a program that addresses the printer or by embedding printer comman ds in files printed by your word processing or other application program.
Page 65: Orientation
LPRINT "Don't send CR/LF"; Because the GQ-3500 prints one page at a time instead of one line at a time, no printing takes place until a form feed (FP) command or a full page of data is received.
Page 66: Font Selection
Font Selection If you have any IC font cartridges or user-defined (download) fonts for your GQ-3500, you have a wide variety of typestyles and sizes available to enhance the appearance of your printed documents. Even without these options, however, the GQ-3500 has many print variations.
Page 67 For normal width or height, use a 1; for double-wide or double-high type, use a 2; for triple-wide or triple- high, use a 3. The GQ-3500 can print any combination of standard-, double- and triple-height and width. The program below shows some examples. 100 LPRINT CHR$(27);"z";CHR$(l);CHR$(l) 110 LPRINT "normal size"...
Page 68: Character Attributes
Background patterns Another way to change the appearance of your print is to print a background pattern behind part of your text. The GQ-3500 has six pre- defined background patterns and reverse (white type on a black background). All are shown on the next page. It is also possible to define two of your own background patterns.

Page 72: Graphics Primitives
Graphics Primitives The GQ-3500 has a set of commands called graphics primitives. These commands allow you to create an image, store it in the printer’s memory, and print it. You can print an image as many times as you like once it has been stored.
Page 73 For example, to send the value 100 to the printer in graphics mode, you use LPRINT “100” instead of LPRINT CHR$(lOO). The difference is that three codes (1, 0, and 0) are sent to the printer instead of just one (ASCII 100). To see the difference, study the example programs that follow.

Page 75 The values to use for each of the parameters are covered in Appendix A. Like the ruled line command, all measurements are given in 1/3OOths of an inch. The GQ-3500 printer prints using dots that are 1/3OOths of an inch wide, thus the measurement value equals the number of dots needed to print an image.

Page 151 Push back the reset lever shown on page 5-12 while you close the top of the printer. If you do this carefully, the reset lever will go behind a connector in the bottom part of the printer and will be protected from vibration during transportation.
Page 152: Parallel Interface
Appendix F Parallel Interface The GQ-3500 is equipped with a Centronics compatible parallel interface, described in this appendix. You may purchase an optional serial interface from your dealer. Installation and operating instructions for your serial interface come packaged with the interface card and are not included here.
Page 153 Do not change these jumpers unless you understand what they do and have a specific requirement. To change the jumpers, you need to remove the interface from the printer. Chapter 2 tells you how to remove and replace it. See Table 8 bits...
Page 154: Pin Assignments
The first jumper, labeled AUTO on the left and PS3 on the right, controls the AUTO FEED function. The AUTO FEED signal on pin 14 is ignored unless this jumper is in the AUTO position. The second and third jumpers change the state of two of the signals on the interface.
Page 155 4-4 is OFF, the interface will ignore DATA8, giving an effective data length of 7 bits. After reading each character, the printer drops the level of this signal to LOWfor about 10 microseconds to acknowledge that it has read one character. After this pulse the host computer can output the next character.
Page 156 BUSY AUTO FEED IN CHASSIS GND - Description This signal indicates whether or not the printer is ready to receive the next character. Data input is normally possible when this signal is LOW. However, the phase of this signal can be changed so...
Page 157 Dropping this signal to LOW resets the printer to the power-on state. Any data that has been received bythe printer but not printed is lost. This signal is normally HIGH; it must go LOW for at least 50 microseconds in order to reset the printer.
Page 158 Be sure to complete the connection on the return side. To prevent noise, the cable must be shielded and the shield should be connected to the chassis of the host computer or the printer. All the interface signals are ‘ITL level. Both the rise and fall times of each signal must be less than 0.2 microseconds.
Page 159 GQ-3500 Options The GQ-3500 printer is designed to accept a variety of options. The GQ-3500 accommodates an optional serial interface board, which is available from your Epson dealer. In addition, the two IC (Integrated Circuit) slots in the top cover allow the use of IC cards that can add fonts or identity modes to the operation of the printer.

Page 161 No action is required. The printer is in test mode (described in Chapter 1). In this mode, the GQ-3500 prints a vertical line test pattern when the PAPER FEED button is pressed. No action is required. Same as UC, except that it prints a character test pattern instead of a vertical line test pattern.
Page 162 Turn the printer off for a few seconds, then turn it back on. If the same error recurs, then write down the full number displayed (such as E 1 8LJ), turn off the power, and contact a qualified service representative.
