Chapter 1 SETTING UP THE PRINTER Subjects covered in Chapter 1 include - . Locating the printer . Unpacking and inspection (part names) l Setting up and connecting l Loading single sheets l Loading and parking fanfold forms .
UNPACKING AND INSPECTION Checking the carton contents Now unpack the contents of the shipping carton, and check each item in the box against Figure l-l to make sure that you have everything (there should be six items). If any of these items are missing, contact your supplier.
The optional accessories which you may have ordered with your printer are: l Font cartridges (FC-lZ, FC-2Z, FC-3Z, FC-4Z) l RAM cartridge (RC-32Z) l Serial-Parallel converter (SPC-8K) l Automatic sheet feeder (SF- 1ODQ) l Roll paper holder (RH-IOZ) /den tifying printer parts Make an external inspection of the printer.
SETTING UP Place the printer in the desired location, and remove all packing material from inside the top cover. This packing material is intended to prevent damage to the printer while in transit. You will want to keep all the packing material, along with the printer carton, in case you have to move the printer to a new location.
Figutu T-5. installing the ribbon cartridge Figum 1-4. Removing the top cover 1. Turn the tension knob clockwise on the ribbon cartridge to tighten the ribbon if it is slack.
3. The ribbon should pass between the print head and the print head shield (see Figure 1-6). I Figure I-6. Pass the ribbon between the print head and print head shield 4. After you have installed the ribbon cartridge, install the roller unit. 5. Open the rear cover using the two pits on either side.
Hgure 1-7. Install the roller unit onto the printer To replace the top cover, insert the tabs into the slots on the printer case. Swing the front edge down to close the cover. Leave the top cover closed during normal operation. The cover keeps out dust and dirt and reduces the printer’s operating sounds.
Ins falling the optional cartridge This printer has five built-in LQ fonts, and a 7 K-byte (30 K-byte for color printer) printing buffer. You can add more fonts or expand the printing buffer by installing optional cartridges (Font catridge or RAM cartridge).
Connecting the printer to your computer Connect the printer to your computer using a standard parallel interface cable. On a PC or PC/AT-type computer, this means that you use the 25-pin D-type connector at the computer end, and the Amphenol-type 36pin con- nector at the printer end.
LOADING SINGLE SHEETS This section will take you through the procedures for loading single sheets of paper. If you are using the optional automatic sheet feeder (SF-lODQ), refer to the ASF instruction booklet. Automatic loading Single sheets can be loaded manually with the power off, or automatically with the power on.
4. Make sure that the release lever is back. If fanfold paper is already mounted in the printer, press the ( SETpkEillp button to park the paper in the off-line state, then move the release lever backwards. 5. Place a single sheet between the guides, placing the side on which you want to print towards the back of the printer.
Manual loading It is also possible to load paper manually while the printer’s power is off. The procedure is: 1. Place the paper guide in position by inserting the tabs, located on the bottom of the assembly, into the slots on the rear cover of the printer.
LOADING AND PARKING FANFOLD FORMS Fanfold forms have holes along the sides and perforations between the sheets. They are also called sprocket forms, punched forms, or just plain “computer paper”. This printer accepts forms up to 10” wide. This section will take you through the procedures for loading, parking and unparking fanfold forms.
6. Move the tractor units downwards by gripping the positioning levers on both side of the tractor unit as shown in Figure 1-13. Figure T-73. Move the tractor units downwards for loading the paper from the rear 7. With the tractor covers open, mount the paper by aligning holes with the pins on the tractor unit.
8. Adjust the spacing of the tractor units by sliding them along the bar, using the clamp lever at the back of each unit to release and lock them in position. When the clamp lever is up, the unit is released, and when it is down, the unit is locked. 9.
Loading the paper from the bottom of the printer You can load the fanfold paper from the bottom of the printer with the following procedure. 1. Remove the top cover and the roller unit. 2. Open the rear cover using the two pits at the side, and push backwards.
Figure 7-77. Install the roller unit after mounted the fanfold paper from the bottom of the printer. 7. Now close the tractor covers, again making sure that the paper holes are aligned with the pins on the tractor units.
4. Press the ( 5E’phE&C’ I button on the control panel. The printer will automatically feed the fanfold form backward until the paper is completely free of the platen. 5. Move the release lever to the back. 6. Mount the paper guide in the upright position.
LOADING MULTI-PART FORMS You can print on continuous multi-part forms with the built-in tractor unit. You can use multi-part forms that have up to five parts including the original when the Multi-part mode is selected with the EDS setting. (For details, please refer to Chapter 3.
ADJUSTING THE PRINTING GAP The distance between the print head and the platen can be adjusted to accommodate different paper thicknesses. To make this adjustment, remove the top cover. The adjustment lever is located at the left side of the printer mechanism.
The following table provides the recommended lever positions for each paper types as a reference. Paper Type Single 2-PlY Weight (g/m2) Thickness (mm) (Each paper) (Total) 52 - 82 0.07 - 0.10 83-90 0.11 - 0.12 40 - 58 0.12 - 0.16 Recommended Lever position 2nd 3rd 3rd 3-PlY 4-PlY 40-58 40 - 58 0.
MEMO.
The control panel buttons can be pressed individually to perform the opera- tions indicated by their names. Other functions can be achieved by holding these buttons down when you turn the printer’s power on, or by pressing the control panel buttons in combination.
24 ON LINE button The ( ON LINE ) button sets the printer on-line and off-line. The status changes each time you press the button. When the printer is on-line, it can receive and print data from the computer. When the printer is off-line, it stops printing and sends the computer a signal indicating that it cannot accept data.
If you alSO press the ( ON LINE ) button while you are line-feeding, t.he paper will feed automatically to the top of the next page. This is explained later. If you press this button while on-line, this will alternately flash the QUIET indicator on and off.
FONT button This button selects the font to be printed. Draft font is selected at power-up unless the default settings are changed. To change to HS Draft (High-Speed Draft) or one of the LQ (Letter Quality) fonts, set the printer off-line, then press the CFONt, button repeatedly until the indicators beside the desired selection illuminate.
POWER-UP FUNCTIONS In addition to their normal functions, all the control panel buttons have special functions that operate if you hold them down while switching power on.
I Long test mode t If the printer is turned on while the (PAPER FEED) button is pressed, the printer will enter the long self-test mode. The printer will print the version number of the printer’s ROM and the current EDS settings, followed by the whole character set printed in each font and pitch available.
Since the self-test occupies the full width of the carriage, it is recommended that the printer is loaded with the widest paper possible to avoid damage to the print head and/or platen. In addition, the total number of lines printed is considerable, more than can be accomodated on a single sheet, so fanfold paper is recommended for this test.
Hexadecimal dump This feature is useful for programmers who are debugging printing pro- grams and want to see the actual codes the printer is receiving.
L.. c Most BASICS, however, are not quite that straightforward. For example, the IBM-PC will give you a printout similar to Figure 2-6. 00 01 02 03 04 05 06 07 08 09 OA OB OC OD OA OE . . . . . . . . . . . . . OF 10 11 12 13 14 15 16 17 58 19 1B 1C 1D 1E 1F .
SWITCH COMBINATION FUNCTIONS Several additional functions can be achieved by pressing the control panel buttons in combinations. Top of Form - Figutu 2-7. Switch combination functions of control panel Form feed If you are using single sheets, this operation ejects the current page.
3. Press and hold the ( ON LINE > button. 4. While holding the ( ON LINE )button down, press the (PITCH) button, then release both buttons at the same time. The printer will beep to indicate that the top-of-form position has been set. Forward micro-feed For fine alignment, you can feed the paper forward in very small increments as follows: 1.
This value will remain unless you power off the printer. If you want to retain this value even after you turn off the power, store it using the Macro Definition function, which is described below. Note that you can only change this value immediately after loading paper.
Selecting the print color Normally, the color printer prints with black even if the color ribbon is installed. Without the aid of software, you can change the printing color as follows: 1. 2. 3. 4. Press the ( ON LINE ) button to set the printer off-line.
l Current print color (color printer only) Data to be stored are controlled in Standard mode and IBM mode separately. For example, the data stored in the Standard mode are not effective in the IBM mode, and vice versa.
Chapter 3 DEFAULT SETTINGS Most printers use a bank of DIP (Dual In-line Package) switches inside the printer to achieve various functions. However, this printer can change the power-up default settings by using the Electronic DIP Switch (EDS) mode. This chapter explains how to use the EDS mode.
FUNCTIONS OF THE EDS SElTlNGS The printer is factory-set with all EDS switches in the ON position. These are the standard settings. By changing the settings, you can alter various printer functions to match your requirements. The following questions will help you choose the proper settings.
Switch A-l: Do you want to use the printer in Standard mode or IBM mode? Select the mode compatible with your computer and software. In Standard mode the prinlcr operates like the Epson LQ-860. In IBM mode it operates like the IBM Proprintcr X24E. The ON position selects Standard mode.
Switch B-l: Are you going to print on multi-part paper? You can use up to 3-ply paper when this switch is ON. If you want to print on 4-ply or 5-ply paper, set this switch to the OFF position.
Switches C-3 and C-4: What is the page length of your paper? I j Leave these switches ON if you will bc using 1 l-inch forms. You will need to change the switches if you will be using a different page length as shown ( below: Switch D-l: The action of this switch depends on the mode chosen with switch A-l.
Except in the Standard Italic character set, these switches select the default character code page as shown below: IBM Code Page D-2 D-3 D-4 IBM Code Page D-2 D-3 D-4 #437 U.
BIDIRECTIONAL TEST/ADJUSTMENT MODE This mode is used to adjust the alignment of the print head on successive bidirectional passes. After a period of some months, your printer may work itself out of alignment on left and right printing passes. This will be most evident in graphics printing.
