Introduction 1

Options
You may choose a cut-sheet feeder, a pull tractor unit, or a roll paper holder to enhance use of your printer. For detailed information on these options, see Chapter 4.
Single-Bin Cut-Sheet Feeder (C806121)
The cut-sheet feeder gives you easier and more efficient handling of single-sheet paper. It automatically feeds up to 150 sheets of standard bond paper into the printer.
Pull Tractor Unit (C800061)
The pull tractor unit improves continuous paper handling. It is especially useful with continuous multi-part forms.
Roll Paper Holder (#8310)
The optional roll paper holder allows you to use the many different types of 21.6 cm or 8-inch roll paper sold for telexes and similar machines.

Interface Boards

Optional interface boards are available to supplement the printers built-in parallel interface. Guidelines for choosing the right interface are given in Chapter 4.

Finding Your Way Around

This manual provides illustrated, step-by-step instructions for setting up and operating your printer.
Chapter 1 contains information on unpacking, setting up, testing, and connecting the printer. Be sure to read this chapter first. Chapters 2 and 3 include important information on paper handling and the day-to-day operation of your printer.
Chapter 6 contains troubleshooting information. If the printer does not operate properly or the printed results are not what you expect, see Chapter 6 for a list of problems and solutions. Other chapters contain information on general maintenance, specifications, and printer commands. There is also a glossary of printer terms and an index.

Choosing a Place

for the Printer
Note: If you plan to use a printer stand, follow these guidelines:
Use a stand that supports at least 11.6 kg (25 lbs), which is twice the weight of the printer. Never use a stand that tilts the printer at an angle of more than 15 degrees from horizontal. If you install a cut-sheet feeder, keep your printer absolutely level. If you position the paper supply below the printer stand, make sure that you allow enough clearance (25 mm or 1 inch) to keep the paper from catching on the underside of the stand. Also see that the distance between the stands supports is at least 280 mm (11 inches), to accommodate any paper size you may use. Position your printers power cord and interface cable so that they do not interfere with paper feeding. If possible, secure the cables to the printer stand.

Assembling the Printer

After choosing a good place for your printer, the next step is to install the platen knob.
Installing the platen knob
You use the platen knob to manually feed paper in the printer when the printer is turned off. You will find the platen knob packed in an indentation in the white foam packaging material. 1. Insert the knob into the hole on the printers side and rotate it slowly until it slips onto the shaft.
Push firmly on the platen knob until it fits against the printer case.
Installing the ribbon cartridge
Before installing the ribbon cartridge, make sure that the printer is not plugged into an electrical outlet. 1. Raise the printer cover to the upright position. Then lift the cover up and off.
2. Slide the print head to the middle of the printer. Then open the paper tension unit cover.
3. Turn the ribbon-tightening knob in the direction of the arrow. This removes slack from the ribbon, making it easier to install.
4. Hold the ribbon cartridge by its handle and push it firmly down into position, making sure the plastic hooks fit into the slots.
Note: Press lightly on both ends of the cartridge to make sure the plastic hooks are properly seated. Setting Up the Printer
Use a pointed object, such as a ball point pen, to guide the ribbon between the print head and ribbon guide while you turn the ribbon-tightening knob to help feed the ribbon into place.
Slide the print head from side to side to make sure that it moves smoothly. Also check that the ribbon is not twisted or creased. Close the paper tension unit cover.
Attaching the paper guide

8. To end the self test, be sure the printer is not printing. Press the LOAD/EJECT or LINE FEED button to eject the paper. Then turn off the printer.
CAUTION: After turning the power off, always wait at least five seconds before turning it back on. Turning the power on and off rapidly can damage the printer.

Note: If the test did not print satisfactorily, see Chapter
Connecting the Printer to Your Computer
If the self test printed correctly, you are ready to connect your printer to the computer. Most computers have a parallel interface. To connect such an interface, use a suitable shielded cable as described in the next section.

The parallel interface

Connect the parallel interface cable as described below: 1. Make sure that both your printer and computer are turned off. Plug the cable connector securely into the printer. Then squeeze the wire clips together until they lock in place on either side of the connector.
Note: If your cable has a ground wire, connect it to the ground connector beneath the interface connector.
2. Plug the other end of the cable into the computer. (If there is a ground wire at the computer end of the cable, attach it to the ground connector at the back of the computer.)
Setting Up Your Application Software
Most application programs let you specify the type of printer you are using so that the program can take full advantage of the printers features. Many of these programs provide an installation or setup section that presents a list of printers.

Slide the edge guides together so that they meet at the center of the papers width. Lower the paper guide onto the back of the printer. Pull the paper release lever forward to the continuous paper position. Press the LOAD/EJECT button to feed the continuous paper to the loading position. Press the ON LINE button to set the printer on line so it can accept data.

Paper Handling 2-9

Printing on Special Paper
In addition to printing on single sheets and continuous paper, your printer can also print on a wide variety of paper types, such as labels and multi-part forms. Before printing on special types of paper, you may need to change the paper-thickness setting. CAUTION: l When printing on labels or multi-part forms, make sure that your application program settings keep the printing entirely within the printable area.
Always return the paper-thickness lever to position 2 when you go back to printing on ordinary paper.
The paper-thickness lever
For normal use, set the paper thickness lever to position 2.
When printing on other types of paper, set the paper thickness lever according to the table below.
Paper type Ordinary paper (single sheet or continuous) Thin paper 24 lb paper (single sheet) Multi-part forms 2-sheet 3-sheet Labels Envelopes Air mail Plain Bond (20 lb) Bond (24 lb) Lever position 4 or 6 7

Multi-part forms

With the pull-tractor installed, your printer can print on continuous multi-part forms of up to three parts (including the original). Make sure you set the paper thickness lever to the proper position using the table above.

Labels

When printing labels, always choose the type mounted on a continuous backing sheet with sprocket holes for use with a tractor. CAUTION: l Never feed labels backward through the printer. Labels can easily peel off the backing and jam the printer.
Since labels are especially sensitive to temperature and humidity, use them only under normal operating conditions. Do not leave labels loaded in the printer between jobs; they curl around the platen and may jam when you resume printing.

Envelope

You can load envelopes just like single-sheet paper. However, you you should pay attention to the special considerations below:

condition.

CAUTION: Only use envelopes under normal operating
Always set the paper-thickness lever to the position indicated for envelopes in the paper-thickness lever section in this chapter. Always feed envelopes by inserting the wide edge into the printer. Make sure your application software keeps the printing within the printable area of the envelopes you are using.

8. Turn on the printer.

Paper handling
1. Pull the left and right rear tabs on the cut-sheet feeder forward until the paper guides retract and lock open to allow for paper loading.
Slide the left paper guide to where the fin on the edge guide aligns with the arrow on the front panel. Next, slide the right paper guide to roughly match the w
Take a stack of paper and fan it. Tap the side and bottom of the paper on a flat surface to even up the stack.
CAUTION: Do not use multi-part forms, carbon paper,
or labels in the cut-sheet feeder.
4. Insert the paper along the left paper guide. Then adjust the right paper guide to match the paper width. Make sure that the paper can move freely up and down. 5. Push the rear tabs on both paper guides backward to clamp the paper against the guide rollers.
A new sheet of paper loads automatically whenever a printable character or line feed command is sent to the printer while the ON LINE light is on.
Note: Run the self test in the cut-sheet feeder mode. The
printer counts the number of lines on the page in l/6-inch line spacing and prints out this number at the bottom of the first test page. Use this number to set the lines-per-page with your software.
Switching between the cut-sheet feeder and push tractor
You can easily switch between continuous paper and cut-sheet feeder operation without removing the continuous paper.
Switching to continuous paper
1. If any single sheets are in the printer, press the ON LINE button to set the printer off line, then press the LOAD/EJECT button to eject. 2. Place the paper-release lever in the continuous paper position.

CAUTION: To prevent paper feeding problem, when printing multiple pages, fold the first printed page forward after the perforation passes the printer cover edge. Switching to the cut-sheet feeder
1. If any printed sheets remain in the printer, press the ON LINE button to set the printer off line, then press the FORM FEED button to advance any printed continuous paper. 2. Tear off the printed pages. 3. Press the LOAD/EJECT button. The printer feeds the continuous paper backward to the standby position. The paper is still attached to the push tractor but is no longer in the paper path.
CAUTION: Never feed labels backward. Labels can easily come off their backing and jam the printer.
4. Place the paper-release lever in the single-sheet position.

Single sheet insertion

Your cut-sheet feeder also has a single sheet loading feature. This feature is especially useful because it allows you to switch to a different type or size of paper (for one sheet only) without replacing the stack of paper in your cut-sheet feeder. 1. Press the ON LINE button to set the printer off line.
2. Align the single sheet to be fed with the mark on the left

T h e ON LINE t i g h t is on but nothing is printed. Check that the software is installed properly for your printer. Check the softwares printer settings. Check both ends of the interface cable between the printer and the computer. Make sure your interface cable meets both the printer and computer specifications.
T h e PAPER OUT tight is on. Load paper into the printer. If paper is already loaded, the paper may be set too far to the right for detection by the paper sensor. Move the paper a little to the left.
The printer sounds like it is printing, but nothing is printed. The ribbon cartridge may not be installed properly. See the section on ribbon installation in Chapter 1. The ribbon may be worn out. Replace the ribbon cartridge. Check the paper-thickness setting.
The printer makes a strange noise, the buzzer sounds several times, and the printer stops abruptly. Turn off the printer and check for paper jams, a jammed ribbon, or other problems and try to print again. If the printer still does not print correctly, contact your dealer or a qualified service person.

If the printer still does not print correctly, try the self test described in Chapter 1. If the self test works properly, the printer is all right, and the problem probably lies in the computer, the software, or the cable. If the self test does not work, contact your dealer or a qualified service person.

Troubleshooting 6-7

The following section guides you through problems in handling single sheets and continuous paper. If you are having problems using the optional cut-sheet feeder, see the section on options starting on 6-10.
Single sheets do not feed properly.
Printing starts too tow on the page, or the bottom part o f one page is printed at the top of the next page. Be sure to choose the correct printer when you choose a printer from your application programs menu. See Chapter 1. If possible, specify single-sheet paper with your application software. Use your application software to reduce or eliminate the top margin and reduce the page length.
When you press the LOAD/EJECT button, the platen does not rotate and paper does not feed. If the ON LINE light is on, press the ON LINE button once to set the printer off line.
When you press the LOAD/EJECT button, the platen rotates but paper does not feed. Check that the paper-release lever is pushed back to the single-sheet position.
The paper feed is crooked or the paper jams. The cut-sheet feeder mode may be turned on. Set DIP switch 2-2 off. Make sure the paper size is within the specified range. See 7-3.
The paper does not fully eject. See that the page-length setting is correct.
Continuous paper does not feed properly.
The paper feed is crooked or the paper jams. See that the paper-release lever is pulled forward to the continuous-paper position. Make sure that the paper supply is not obstructed by a cable or some other object. Make sure that your paper supply is positioned within 1 meter (3 feet) of the printer. The position of your paper supply may be preventing it from feeding straight. See that the holes on the sides of the paper are aligned with each other. Also, make sure the sprocket units are locked and their covers are closed. Check that the paper-thickness lever is set correctly for the paper you are using. Check that the paper size is within the specified range. See 7-3.

Troubleshooting 6-9

This section describes problems you may encounter while using an option with your printer.
When you use the cut-sheet feeder, the paper does not feed properly.
When a print command is sent from the computer, the platen rotates but paper does not feed. Make sure DIP switch l-8 is set on. See the section on DIP switches in Chapter 3. The cut-sheet feeder may be incorrectly installed on the printer. See that the paper-release lever is pushed back to the single-sheet position. You may have loaded too many sheets in the cut-sheet feeders bin. Paper may be jammed near the print head. There may be only one sheet left in the bin. Add more paper.
Two or more sheets feed at one time. You may have loaded too many sheets in the cut-sheet feeders bin. You may have forgotten to fan the stack of paper before loading it into the bin. Remove the paper and fan it.
The paper feed is crooked. The paper may be old or creased. Use only new, clean sheets of paper. There may be too much paper in the stacker. Make sure that the paper guides are set correctly and that your paper is the proper size and quality.
One page of printing has spread to two pages. Check that the page-length setting and lines-per-page setting in your software are correct.
Switching between the cut-sheet feeder and the push tractor does not work properly.
You press the LOAD/EJECT button to toad paper, but the desired paper type does not toad. The paper release lever may not be in the proper position. Pull the lever forward to load continuous paper or push the lever back to load single sheets.
When you change the paper-release lever position, the printer beeps continuously. You may have changed the paper-release lever position while paper was in the paper path. Return the paper release lever to its former position and press LOAD/EJECT button. Then move the lever.
When you press the LOAD/EJECT button to eject continuous paper, the paper jams or does not fully eject. You may have tried to reverse feed too many pages. Before ejecting the paper, always tear off the last printed page. Never press the LOAD/EJECT button more than twice.

Using the pull tractor with the push tractor, continuous paper does not feed properly.
W h e n y o u p r e s s t h e FORM FEED or LINE FEED b u t t o n , t h e platen does not rotate and paper does not feed. The printer may be on line. Before using the control panel buttons to feed paper, always set the printer off line.
Paper feed is crooked or the paper jams. Something may be obstructing the paper feed. Make sure that the paper can feed smoothly into the printer. The supply of paper may be too far from the printer. Position the paper supply so that it is no more than 1 meter (3 feet) from the printer. The paper may be caught on the edge guides. Make sure that the paper guide is installed over the paper and that the edge guides are positioned at the center of the papers width. The pull tractor and push tractor sprockets are not aligned correctly. When using both tractors, be sure that the sprockets on both are positioned evenly. The paper may have too much slack. Adjust the position of the sprockets to take up any slack along the width of the paper. Remove slack lengthwise by pressing in and rotating the pull tractor feed knob on the right. The paper thickness lever may not be set correctly. Set the paper thickness lever to match the thickness of your paper. The paper may not meet the specification for your printer. Check that your paper is of the proper size, weight, and thickness. See Chapter 7.
Several tines of space occur in the printout. Skip-over-perforation may be set. Set DIP switch 2-3 to off.
Skip-over-perforation is set but does not work. You may have changed the DIP switches with the power on. To make new DIP switch settings effective, turn the power off, then on again.
Skip-over-perforation is set, but the skip has shifted from the perforation, or the perforation does not fall in the center of the skip. The page length for one page of the continuous paper may be set incorrectly. Set DIP switches 1-3 and l-4, or use control codes ESC C or ESC C 0 to set the correct page length. The loading position of the paper may be too high or too low. Use the microadjustment feature to reset the loading position.
When printing ends, the paper feeds abruptly, and as it resumes printing, the paper feeds backward and comes off the putt tractor sprockets. You may have selected the short tear-off, which you cannot use with the pull tractor. Be sure to set DIP switch 2-l on.
