Chapter 1: Printer Setup

This chapter contains important information on setting up your printer. Be sure to read this chapter carefully before using the printer for the first time. In this chapter you will learn about:

☐ Choosing a place for the printer
☐ Unpacking and setting up the printer
☐ Installing the ribbon cassette
☐ Connecting to a host computer
☐ Inserting paper

Choosing a place for the printer

Before actually unpacking the printer, you should take a few minutes to think about where you plan to use it. Remember the following points when doing this.

√ Choose a firm, level surface where the printer will not be exposed to vibration.
√ The power outlet you plan to connect to for power should be nearby and unobstructed.
√ Make sure that the printer is close enough to your host computer for you to connect the two.
√ Make sure that the printer is not exposed to direct sunlight.
√ Make sure that the printer is well away from heaters and other sources of extreme heat.
√ Make sure that the surrounding area is clean, dry, and free of dust.
√ Make sure that the printer is connected to a reliable power outlet. It should not be on the same electric circuit as copiers, refrigerators, or other appliances that cause power spikes.
√ Use a power outlet that matches the power rating noted on the label affixed to the bottom of your printer.
√ Make sure that the room where you are using the printer is not too humid.

Unpacking the printer

Check to make sure that the carton contains each of the items shown in the following illustration.

Important!

We recommend that you unplug the printer from the power outlet whenever you do not plan to use it for long periods. Because of this, you should locate the printer so that the power outlet it is plugged into is nearby and easy to access.

At this point you may want to perform a test of the printer to make sure it is working properly. See page 15 for details on how to test the printer.

Connecting to your host computer

The computer sends data to the printer through a cable to the printer's interface (Serial Interface Connector Type: D-sub 25-pin or Parallel Interface Connector Type: 36-pin Centronics compatible). This printer does not come with a cable, so it is up to you to obtain one that suits your needs.

Important!

- The following instructions apply to the cable that is used with an IBM-compatible personal computer. Note that they do not apply to all types of computers and cables. If you are unsure about what type of cable you should use to connect with your computer, consult your dealer.

- Make sure that the printer is turned off and unplugged from the AC outlet and that the computer is turned off before connecting them.

☐ Affix the larger ferrite core onto the cable as shown in the illustration below.

Pass the fastener through the ferrite core.

5 cm maximum Fastener

Loop the fastener around the cable and lock it. Use scissors to cut off any excess.

Pull and cut

For a serial cable:

☐ Plug one end of the serial cable into the serial port of your computer, and the other end of the cable into the socket on the back of the printer. Secure both connectors in place with the screws that are provided.

For a parallel cable:

☐ Attach a ferrite core in the same way that one is attached to a serial cable.
☐ Plug one end of the parallel cable into the parallel port of your computer. The parallel port should be labeled “Printer”, “Parallel”, “PRN”, “LPT1” or something similar.
☐ Plug the other end of the parallel cable into the socket on the side of the printer and secure it in place with the clips.

Connecting to a peripheral unit

You can connect a peripheral unit to the printer using a modular plug. The following describes how to install the ferrite core and make the actual connection. See “Modular plug” on page 137 for details about the type of modular plug that is required. Note that this printer does not come with a modular plug or wire, so it is up to you to obtain one that suits your needs.

Important!

Make sure that the printer is turned off and unplugged from the AC outlet and that the computer is turned off before making connections.

☐ Affix the smaller ferrite core onto the modular wire as shown in the illustration below.

Ferrite core (20 mm diameter) Connector Cable

Pass the fastener through the ferrite core.

5 cm maximum Fastener

Loop the fastener around the cable and lock it. Use scissors to cut off any excess.

Pull and cut

☐ Plug one end of the modular cable into the modular jack of the peripheral.

☐ Remove the modular jack cover from the back of the printer and plug the other end of the modular cable into the jack of the printer.

Inserting the paper into the printer

Use only the specified type of paper for this printer. Do not use inappropriate types of paper, or it could cause malfunction or damage of the printer.

The following procedure describes how to print on paper. Before trying to print, be sure to install a ribbon cassette into the printer using the procedure under “Installing the ribbon cassette” on page 4.

☐ Make sure that the printer is plugged in and turned on.

☐ Check that the RELEASE indicator on the control panel is lit. If the indicator is not lit, press the RELEASE button until the indicator lights up.

Important!

Insertion and removal of paper should be done only when the printer is released condition (the paper is not held by paper feed roller).

Place a piece of the paper onto the printer's document table and slide its right edge into the printer. Printing will be performed on the side of the paper that is facing up (the one you can see), starting from the top of the paper.

Important!

Do not use wrinkled or curled paper. In case of multiple paper, neatly align the sheets.

Though paper can be inserted either from the front or side of the printer, front paper insertion may result in paper jams, depending on the condition of the paper. Because of this, it is recommended that you always insert paper from the side.

AutoSide Loading™

This printer is equipped with paper sensors, so you do not have to perform any special procedure to align the location from which printing should start. Simply insert the paper into the printer and the sensor locates the top of the paper. The paper will be moved automatically into position for printing.

Important!

When inserting the paper into the printer, make sure that there are at least 3 cm between the top edge of the paper and the print start position mark on the printer. Otherwise the paper sensor may not be able to correctly locate the top of the paper.

At least 3 cm Print start position mark

☐ Push the right edge of the paper into the printer until it stops. At that time, the PAPER OUT indicator will go out, and the printer mechanism will automatically align the paper for printing from the top.
☐ Send data from your host computer to be printed on the paper.
☐ After printing, press the RELEASE button to automatically release the paper.

Chapter 2: Control Panel Operations

The control panel gives you some push-button control over the slip printer operation. It also includes indicator lights, which tell you the current status of the printer at a glance.

POWER RELEASE PAPER OUT FORWARD REVERSE RELEASE

Indicator lights

The following table describes the meaning of indicator lights when it is on, off, or flashing.

Indicator Light Off	On Flashing
POWER	Power off Power on		Dot Alignment Adjust Mode
PAPER OUT	Paper inserted No paper insert paper prompt
RELEASE	Slip paper engaged Slip paper released Mechanical error

Buttons

The following table describes the function of the three control buttons of the control panel.

Button Description
FORWARD	Feeds the slip paper forward, toward the back of the printer. One press feeds one line, holding down performs continuous feed.
REVERSE	Feeds the slip paper back, toward the front of the printer. One press feeds one line, holding down performs continuous feed.
RELEASE	Activates the printer's paper release (the paper is not held in place by the paper feed roller).Clears recoverable errors.

Producing a test print

The following procedure can be used at any time to test the printer.

☐ Turn on the printer and insert a piece of paper (page 6, 11).
Turn off printer power.
☐ While holding down RELEASE, turn printer back on. Keep RELEASE depressed for a few moments until the printer beeps and the printer test print starts.

The printer test will continue until it reaches the end of the paper.

Adjusting the dot alignment

You may never have to use the procedure described in this section, but after you have been using your printer for some time you may find that the dots of some graphics do not align correctly. For example, what should look like:

may come out looking like one of the following:

or like this

This is caused when mechanical parts of the printer get out of alignment. This happens only rarely and you may never experience it at all throughout the life of the printer. If you do have problems, use the following procedure to correct it.

☐ Turn on the printer and insert a piece of paper.
Turn off printer power.
While holding down the control panel's FORWARD and REVERSE buttons, turn the printer back on to enter the Dot Alignment Adjust Mode, which is indicator by a flashing POWER indicator flashes.

Entering the Dot Alignment Adjust Mode causes seven blocks to be printed, each of which indicates a dot alignment setting, as shown below. An asterisk to the left of the blocks indicates which block is currently selected.

Dot Alignment Adjust Mode *

☐ Use FORWARD to specify the block that appears to have the best aligned characters. Press FORWARD once to specify the first block, twice to specify the second block, and so on up to seven times to specify the seventh block.

Warning beep will sound if you press FORWARD more than seven times.

☐ After specifying a block, press REVERSE to register your selection and exit the Dot Alignment Adjust Mode.

The dots alignment adjustment setting you selected is stored in printer memory and a pattern is printed using the selected setting followed by the message “Adjust Complete!” The printer ejects the paper after printing is complete.

* Adjust Completed!

Note:

You setting is not registered if you turn off printer power before pressing REVERSE to exit the Dot Alignment Adjust Mode. If a paper feed error occurs during this mode, the printer ejects the paper and this mode is cancelled.

Hexadecimal dump

This procedure prints in hexadecimal format all codes (character codes and control codes) that are sent to the printer by the computer. The printer does not execute any control codes (such as 0A - linefeed), it just prints them out. The hexadecimal dump is useful when you are writing programs for printer control.

Turn on the printer and insert a piece of paper.
Turn off printer power.
While holding down the control panel's FORWARD buttons, turn the printer back on to enter the Hex Dump Mode.
☐ To exit the Hex Dump Mode, turn the printer off.

Note:

The printer will not responde to any commands you send it while it is in the Hex Dump Mode.

Errors

There are three types of errors: recoverable errors that require some action by you before they clear, non-recoverable errors that require servicing by an authorized service provider, and a data receive error. Errors are indicated by and audible buzzer and the indicators.

Recoverable Errors

Error Type	Indicators			Recovery
	POWER RELEASE PAPER OUT
Paper jam		Flashing		Correct the cause of the problem and then press RELEASE.
Carriage motor lockup
Abnormal home position signal
Abnormal timing signal

Non-recoverable Errors

Error Type	Indicators			Recovery
	POWER RELEASE PAPER OUT
RAM read/write	Off On On			Turn off the printer, then after waiting a few minutes, turn the printer back on. If the printer does not recover, contact your nearest service provider.
CPU lockup

Data Receive Error

This type of error is caused whenever a problem is encountered during data receipt. The method used by the printer to recover from a data receive error depends on the current command mode.

Command mode Data Receive Error Recover Procedure
Star mode The printer prints a question mark.
ESC/POS mode	Memory switch 4-0=0 : The printer prints a question mark.Memory switch 4-0=1 : The printer discards the received data.

Paper Sensors

The following paper sensors are available.

TOF Sensor

This top-of-form sensor detects the leading edge of the paper.

When enabled, the TOF sensor detects when there is no paper present and stops printing.

BOF Sensor

This bottom-of-form sensor detects the trailing edge of the paper. When enabled, the BOF sensor detects when there is no paper present and printing is interrupted.

When the TOF or BOF sensor detects that no paper is present, the printer stops its motor after printing of 0 to a maximum of two more lines.

The BOF sensor detects a paper out condition whenever the distance between print head pin #9 and the trailing edge of the paper becomes 38.1 mm or less. In the Star Mode, this enters the print stop operation, but in the ESC/POS Mode, the print stop operation is not entered until the distance between print head pin #9 and the trailing edge of the paper becomes 27.3 mm or less.

When the auto clamp is enabled with Memory Switch 5-1, the auto clamp operation is performed about 0.7 second (initial default in Star Mode; ESC/POS Mode initial value is approximately 1 second) after the presence of paper is detected both by the TOF and BOF sensors, following a paper out condition. The auto clamp function is not affected by whether the TOF or BOF sensor is enabled or disabled.

The top of form positioning function is enabled with Memory Switch 5-0. Even if the auto clamp function is disabled, auto top of form positioning is performed if the paper is clamped when printing starts.

The PAPER OUT lamp flashes to request insertion of paper when the sensors detect there is no paper (when a sensor enabled by command detects no paper) after data is received by the printer. At that time, the user inserts paper, and printing begins after the sensor detects that paper is present.

Chapter 3: Command Summary

This printer supports two different command modes: the Star mode and the ESC/POS mode.

The Star mode emulates previous Star printers. The ESC/POS mode emulates the Epson TM-295 or TM-290 slip printer.

This chapter provides you with all of the commands supported by this printer.

Appendix B: Making DIP Switch Settings

The printer's DIP switches let you specify communications parameters, receive buffer size, and emulation. This Appendix explains the settings you can make and tells you how to actually change DIP switch settings.

Accessing the DIP switches

The DIP switches are located inside the printer, underneath the document table. Use the following procedure to remove the document table so you can operate the DIP switches.

☐ Make sure that the printer is turned off and unplugged from its wall outlet.
☐ Remove the printer cover.
☐ While using a screwdriver or other similar instrument to press down at the location marked (a) in the illustration below, carefully slide the document table in the direction indicated by the arrow until it is out of the way.

Technical line drawing of a mechanical assembly with a tool inserted, showing internal components and a directional arrow (no text or symbols)

It is not necessary to remove the document table completely, just move it enough so you can get at the DIP switches inside.

ON ↑ ↓ OFF 1 2 3 4 5 6 7 8 9 1 0 (For Serial Interface) ON ↑ ↓ OFF 1 2 3 4 5 6 7 8 (For Parallel Interface)

Note:

If the document table seems to be getting caught on the rollers, it means that you are not pressing down at point (a) enough. Pressing at point (a) should separate the rollers to the document table can slide freely.

☐ After the document table is opened sufficiently, use a thin flat-blade screwdriver or some other similar object to change DIP switch settings.

Note:

See the following section for details on available DIP switch settings.

After making the settings you want, slide the document table back into place while pressing down at point (a). Make sure that the document table is correctly seated in place before releasing point (a).
Replace the printer cover.

Available DIP switch settings (Serial Interface)

The following table shows all the possible settings for the DIP switch. The factory default settings are ON for switches 1 through 7 and OFF for switches 8 through 10.

Note: 1. The prefix “n” on the signal name refers to low active signals. If the host does not have any one of the signal lines listed above, two-way communication fails.
2. For interfacing, signal lines should always use twisted pair cables with the return sides connected to the signal ground level.
3. Cautions when resetting the printer using the nInit signal (#31 pin). Reset can be made from #31 pin (nInit signal) of the interface when the DIP switch 1 is set to on. (Factory setting is on.) In addition, when reset has been enabled by #31 pin (nInit signal), it can be set to reset when the following conditions have been established: DIP switch 2 has been set to off, #36 pin (nSelectIn/1284 active signal) is low, and #31 pin (nInit signal) is low.
4. During factory output, IFEE 1284 printer device ID reply will be “Invalid.” To get the device ID, change DIP switch 6 to “OFF (Valid).”

Function for compatibility mode

Pin No.	Signal Name IN/OUT Function
1 nStorobe IN			Signals when data is ready to be read. Signal goes from HIGH to LOW (for at least 0.5 microsec.) when the data is available.
2-9 Data0-7 IN			These signals provide the information of the first to eighth bits of parallel data. Each signal is at HIGH level for a logical 1 and at a LOW level for a logical 0.
10 nAck OUT A 9 microsecond LOW pulse acknowledges receipt of the data.
11 Busy OUT			When this signal goes to LOW, the printer is ready to accept data. When the printer is in one of the conditions below, “HIGH” is set.1. Data is being entered2. Off line3. Error condition
12 PError OUT			This signal indicates the status of the paper sensor.[In Star mode]This signal goes to HIGH when either the TOF or the BOF sensor detects that there is no paper. The signal will go to LOW when both the TOF and BOF sensor detect that there is paper installed.[In the ESC/POS mode]This signal outputs the status of the sensor selected using the“c3” command.
13 Select OUT This signal is HIGH when the printer is online.
14 nAutoFd IN Unused
15 N/C	Unused
16 GND	Signal ground
17 Flame GND			Chassis ground, isolated from logic ground
18 Logic High			3.9 kΩ pull-up
19-30 GND	Twisted pair return the signal to ground level.
31 nInit	IN		This becomes a reset signal when DIP switch 1 is set to ON. (See page 128 for details.) When this signal goes to LOW (for at least 0.5 microsec.), the printer is reset to its power-on condition.
32 nFault OUT			This signal is normally HIGH. This signal goes to LOW to signal that the printer cannot print due to an error condition.
33 EXT GND			External ground
34	Compulsion Status	OUT Compulsion signal (See page 138.)
35 +5	V 2.2 k		Ω pull-up

Notes

- Peripheral Units 1 and 2 cannot be driven simultaneously.

- For continuous driving, do not use drive duty greater than 20% .

- The status of the compulsion switch can be known from the following. Star mode: The status of the compulsion switch can be known by using the automatic status function or commands. In the case of ENQ status, bit 7 will be "1" when pin No. 6 of the peripheral unit drive circuit is high (switch on).

ESC/POS mode : The status of the compulsion switch can be known by using the automatic status function, n, and "u"n commands.

Parallel interface: The status of the compulsion switch can be known by pin No. 34 on the parallel interface connector. When the compulsion switch is on, pin No. 34 will be low. This can be checked by using the compatibility mode.
