2.2.2 Instructions for Installation

The TM-L90 can be placed vertically (paper outlet in front), horizontally (paper outlet at the top), or attached to a wall (using the optional wall hanging set WH-10).

With the TM-L90 Peeler Model, you can use it vertically or wall mounted with either peeling issuing or with continuous issuing (not using the peeler).

Note:

For the TM-L90 Peeler Model, horizontal installation is prohibited to avoid jams caused by re-sticking of backing paper and a label.

The illustration below shows the vertical installation for the TM-L90 Peeler Model.

Note:

To hang the printer on the wall, see the Wall Hanging Bracket Set Installation Manual provided with the WH-10 for instructions.

It is recommended to take some measures so that the printer will be stable when paper is being loaded or a drawer is being used. The DF-10 (affixing tapes) for fixing the printer is provided as an option.

When using the printer with the peeling issuing mode, be sure to install the printer so that a peeled label will not contact the used backing paper. Re-sticking of a peeled label to the backing paper will cause jams.

For the TM-L90, when changing the way of installation, you need to adjust the following items:

• Control panel label used for horizontal installation

• The location of the Roll Paper Near-End Detector

The following figure shows the TM-L90 placed both vertically and horizontally.

34 Setup

TM-L90/TM-L90 Peeler Model Technical Reference Guide

2.5 Autocutter Settings (TM-L90 only)

The TM-L90 has an autocutter attached for cutting the paper. The autocutter can perform 2 cuts, "partial cut," in which a small part is left uncut on the left edge, and "full cut" (default setting), in which the paper is cut completely. By adjusting the attachment position of the cutter unit, you can select between "partial cut" and "full cut."

Note:

You can't configure the autocutter setting (Partial cut/Full cut) through a software command.

You can't change from partial cut setting to full cut setting after using the printer with partial cut setting. Since the partial cut doesn't use the tip of the blade, it might have deteriorated. Contact the nearest Epson service center if you'd like to do the above change.

To disable the autocutter, change the memory switch (MSW2-2) settings. (Refer to "Memory Switch Settings" on page 42).

Performing full cut without the paper exit guide when the printer installed horizontally may cause a doublecut, paper jam or autocutter error because a cut sheet may drop in the paper path. Be sure to attach the paper exit guide when performing a full cut in the horizontal installation. (Refer to "Instructions for Installation" on page 23 for instructions on attaching the guide.)

2.5.1 Cautions on the Lengths of the Receipts/Labels to Issue

• To prevent the cut receipts or labels from getting stuck in the paper path, causing paper jams.

• To make the cut receipts or labels easy to remove

The lengths of the receipts and labels to issue is recommended as shown in the table below.

Use condition Recommended issuing length

Horizontal installation (full cut)*

Horizontal installation (partial cut)*

Vertical installation

Note 1: Install the paper exit guide packed in the box with the printer when the autocutter is used with a full cut, with the printer

positioned horizontally.

2: Partial cut (one point left uncut) is available only when using receipt paper or continuous label paper without black marks.

Also, do not perform cutting and reverse feed together.

Note:

If the lengths of receipts or labels are specified shorter than the recommended lengths, the issued receipts or labels may be hard to remove. Users must make a thorough evaluation of the lengths to specify before using the printer.

protrusion

The TM-L90 / TM-L90 Peeler Model uses a roll paper 80 mm wide in the default state. When using a roll paper 38 to 70 mm wide with this printer, attach the roll paper spacer in accordance with the following procedure.

Note:

If a printer has already been used, the paper width cannot be changed from narrow to wide. This is because the part of the head that made direct contact with the platen may have been damaged when narrow roll paper was used. The paperless part of the cutter blade may also have worn. Only when the printer is not yet used can the paper width be changed from narrow to wide.

The following explains the procedure for setting the roll paper width for the TM-L90.

1. When using 61 mm to 70 mm roll paper, break off the two tabs of the roll paper spacer.

Note:

You can still use widths from 38 mm to 60 mm after breaking the tabs off.

Note:

When you set the baud rate with the memory switch, you can set faster communication than with the DIP switch. (Refer to "Memory Switch Settings" on page 42, "Error Code" on page 111)

In serial communication, intermittent printing* may occur. This is because when the communication speed is low, a data transmission waiting state occurs frequently since the printing mechanism speed is high. Increasing the communication speed may reduce this symptom. * Intermittent printing: White streaks as large as one or two hairs appear horizontally in a printing result.

When [Msw 8-2] is Off, the paper layout is automatically measured and saved into the non-volatile memory of the printer after recovery from the error.

If [Msw8-2] is On, the printer paper layout is not changed after error recovery. If the correct paper is not inserted, the paper layout error will occur again.

The [Msw 8-4] setting influences initialization at power-on when “label paper” or “receipt paper with black mark” is specified for the paper layout. Refer to "Setting Paper Layout" on page 57 for the paper layout.

When [Msw 8-6] is set to "Feeding paper to the print starting position at power on is disabled", the printer does not execute the operation of feeding paper to the print starting position at power on (the printer executes the operation when its cover is opened and closed). Hence, the user should note the following points since the printer operates on the assumption that the paper has already been fed to the print starting position at power on.

a) Turn off the power supply after feeding of paper to the print starting position.

b) Do not open the cover while power is off.

c) If you have opened the cover while the power is off, open and close the cover once while the power is

on to feed the paper to the print starting position. If printing is performed without the operation described above, the paper layout error (recoverable error) may occur. If the error occurs, recover from the error by the operation selected with [Msw8-2].

If the print starting position has not been set at power-on, the printing position of the first sheet may shift, or a paper layout error may occur.

2.9 Paper Loading Method

WARNING:

Do not open the roll paper cover (for the TM-L90 Peeler Model, do not open the peeler cover and the roll paper cover) during the operation. Doing so may damage the printer.

Do not touch the manual cutter with your hands when installing or replacing roll paper. Touching the manual cutter may result in injury.

For the TM-L90, when the printer is placed horizontally, the raised roll paper cover may close suddenly depending on the inclining angle of the printer. Take care not to get your finger caught in it.

Note:

Be sure to use roll paper that meet the specifications.

2.9.1 With TM-L90

1. Open the roll paper cover, using the cover open lever.

2. Pull out roll paper with little paper remaining and insert new roll paper, aligning the paper with the guide, as shown below.

3. Close the roll paper cover; then cut off the paper with the manual cutter.

WARNING:

Be careful that your finger is not inside the printer when you close the cover because you can get your finger caught inside.

Setup 53

2.9.2 With the TM-L90 Peeler Model

With the TM-L90 Peeler, the paper loading method differs depending on whether peeling issuing or continuous issuing is used. They are explained as follows.

Paper setting with peeling issuing

1. Pull the peeler open lever forward, and open the peeler cover.

2. Pull the cover open lever, and open the roll paper cover.

3. If there is a roll paper with little paper remaining inside the printer, take it out.

4. Check that the printer is on. If it is not on, turn it on.

5. Put a new roll paper in the printer. Make sure that the roll paper is oriented as shown in the following figure.

6. Slide the mode switch to the right (peeling issuing mode).

54 Setup

TM-L90/TM-L90 Peeler Model Technical Reference Guide

7. As shown in the following figure, pull the end of the paper to the bottom of the square hole above the manual cutter (label peeling sensor), and close the roll paper cover.

Note:

Matching the leading edge of the roll paper with the printed marks on the printer ensures that the fewest possible labels are ejected automatically.

WARNING:

Do not close the roll paper cover with your finger still inside the roll paper cover. Doing so may lead to injury.

8. A few labels are fed automatically and the PAPER OUT LED starts flashing.

9. Pass the backing paper that you pulled out to the other side of the peeler cover as shown in the following figure, and close the peeler cover.

10. Press the FEED button. The printer automatically feeds the paper to the start position, and the PAPER OUT LED goes off.

Note:

If the paper is not set properly when the FEED button is pressed, there may be label adhesive on the rollers of the peeler. Peel off one label, and remove the adhesive from the roller by lifting it off with the adhesive side of the label. For the cleaning method, refer to page 108. Paper setting with continuous issuing (not using the peeler)

Setup 55

Paper setting with continuous issuing

1. Pull the peeler open lever forward, and open the peeler cover.

2. Pull the cover open lever, and open the roll paper cover.

3. If there is roll paper with little paper remaining inside the printer, take it out.

4. Put new roll paper in the printer as shown in the following figure.

5. Slide the mode switch to the left (continuous issuing mode).

56 Setup

6. As shown in the following figure, pull the end of the paper to the bottom of the square hole above the manual cutter (label peeling sensor).

Note:

Matching the leading edge of the roll paper with the printed marks on the printer ensures that the fewest possible labels are ejected automatically.

7. Pressing down the end of the paper, close the roll paper cover. The printer automatically feeds the paper to the start position.

WARNING:

Do not close the roll paper cover with your finger still inside the roll paper cover. Doing so may lead to injury.

8. Close the peeler cover and cut off the excess paper with the manual cutter.

2.9.3 Setting Paper Layout

Before printing, it is necessary to set the layout information for paper type and size in the printer. Doing paper feeding or printing without this layout setting may result in a paper out (no paper left) or an error. In all of the following cases, therefore, make layout settings before use.

❏ When using label paper for the first time (except when replacing label paper of the same type)

❏ When you change the paper type (full-surface label paper/receipt paper, label paper, receipt paper

with black mark)

❏ When changing the size of the label paper

❏ When you change the liner for one of different transmittance.

There are automatic and manual layout settings. The setting procedure is as follows.

Setup 57

If you use the printer without making a layout setting and a paper out (no paper left) or an error occurs as a result (refer to page 111), opening and closing the cover automatically sets a new layout.

Note:

The above automatic layout setting by opening and closing the cover is available with firmware version

1.05 or later. It enables you to make layout setting by intentionally generating an error in paper feeding on printing. This function can be turned off using the Memory Switch Setting Utility.

Automatic paper layout setting

Automatic paper layout setting sets a paper layout on the basis of the black mark or label position detected by the printer.

This method is available for label paper, receipt paper, and receipt paper with black mark.

Note:

When using label paper with black mark, it is necessary to make manual setting of paper layout (set using the Memory Switch Setting Utility or ESC/POS command).

This automatic paper layout setting can be used with any of the following three methods.

• Use the automatic paper layout setting mode provided for the printer.

• Use the Memory Switch Setting Utility.

• Directly control the printer using ESC/POS commands.

Note:

For the Memory Switch Setting Utility and ESC/POS commands, refer to "Introduction of Control Methods" on page 83.

When using Advanced Printer Driver (APD) or ESC/POS commands, set the print area as required. The print area position influences the paper layout.

Described below is a procedure for automatic setting of paper layout that allows you to independently set the paper layout on the printer.

It is also possible to cause an error intentionally so that the printer will feed several labels and remember the label paper size. See the instructions below.

❏ TM-L90 setting procedure (Procedure for setting the paper type and size to the printer)

1. Install the printer.

2. Connect the power and other cables.

3. Open the roll paper cover.

58 Setup

4. Set the roll paper in the printer.

TM-L90/TM-L90 Peeler Model Technical Reference Guide

5. With the roll paper cover open, turn on the power while pressing the FEED button inside the

printer. (Keep pressing the FEED button until the ERROR LED comes on.)

6. Check that the ERROR LED is on, and release the FEED button.

7. Press the FEED button 6 times.

8. Then, close the roll paper cover.

The printer feeds several labels and remembers the label paper size. This completes the task.

❏ TM-L90 Peeler Model setting procedure (procedure for setting the paper type and size in the printer)

There are the following 2 cases.

1. Open the peeler cover.

2. Open the roll paper cover.

3. Set the roll paper in the printer.

4. With the roll paper cover open, turn on the power while pressing the FEED button inside the

printer. (Keep pressing the FEED button until the ERROR LED comes on.)

5. Check that the ERROR LED is on, and release the FEED button.

6. Press the FEED button 6 times.

7. For peeling issuing, set the end of the roll paper in the peeler, and for continuous issuing, set it in

the ejection path, and close the roll paper cover. The printer feeds several labels and remembers the label paper size. This completes the task.

8. For peeling issuing, after setting the paper, the PAPER OUT LED flashes. To print, insert the label

into the peeler path, and press the FEED button.

Parameters Calculated for Automatic Layout Setting

❏ Manual paper layout setting

Manual paper layout setting is to directly enter paper data into the non-volatile memory of the printer to execute the "paper layout setting" function. As compared to automatic setting, manual setting enables finer adjustment of the paper layout. You can set the paper type, mark-to-mark distance, mark length, paper width and print area.

This "manual paper layout setting" can be used in either of the following two methods. Refer to the corresponding manuals for how to use these methods.

• Use the Memory Switch Setting Utility. (Manual: Memory Switch Setting Utility, User's Manual)

• Directly control the printer using ESC/POS commands. (Manual: ESC/POS Command Reference For details on how to obtain this manual, see "Introduction of Control Methods" on page 83).

Setup 61

Note:

For the Memory Switch Setting Utility and ESC/POS commands, refer to "Introduction of Control Methods" on page 83.

When using the Advanced Printer Driver (APD) or ESC/POS commands, set the print area as required. The print area position influences the paper layout. When using label paper with black mark, always make a manual setting of paper layout.

2.9.4 Clearing Paper Layout Setting

This printer has a function to reset the paper layout set in the automatic paper layout setting mode or by manual setting to the factory setting.

Note:

This function may be unavailable depending on when you purchased your printer. You cannot use this function if the firmware version of the printer printed in a self test ("Memory Switch Settings" on page 42) is

1.04 or earlier. For more information, please contact your sales representative.

The method of clearing the paper layout settings in the printer is as follows.

1. Open the peeler cover.

2. Open the roll paper cover.

3. Load roll paper.

4. Until the ERROR LED is on, hold down the FEED button (on the inside of the roll paper cover: see page 42) and turn on the power supply.

5. When the ERROR LED comes on, release the FEED button (inside the roll paper cover).

• Serial, Parallel, USB, Ethernet, Wireless LAN

Supported OSs (with confirmation of system operation)

For details on the supported operating systems, see the release note of the driver for the latest information.

Supported development languages

For details on the supported development languages, see the release note of the driver for the latest information.

Supported devices

(Refer to the release note of the driver for details of available equipment.)

• Epson receipt printer

• Epson customer display

•Epson cash drawer

Note:

The USB interface models require USB device driver. The Ethernet or Wireless LAN interface models require IP setting utility. For the details, refer to the packaged APD manual.

When the TM-L90 is connected via a serial interface, it is recommended to use the printer resident font since use of the TrueType font will decrease printing speed due to the transfer speed of the serial interface. For how to use the resident font, refer to the PDF User's Manual of APD. The other interfaces (parallel, USB, Ethernet) do not pose problems in terms of the transfer speed but may have some influence on customer applications. In that case, use the printer resident font. When OPOS is used, this problem does not arise because only the printer resident font is available.

5.2 Sensors

5.2.1 Paper Sensors

The printer has two paper sensors.

5.2.1.1 Roll paper near-end sensor

The roll paper near-end sensor is to detect the condition when the remaining amount of the paper is getting low and it is located on the roll paper supply unit. It detects the near-end of the roll paper by detecting the roll paper diameter. You can adjust the sensor position. See page 25 for details for adjustment.

The normal printing task will be performed even in the near-end status.

Note:

The detecting the near-end status of the sensor does not necessarily indicate the complete end of the roll paper. Use the sensor as an indication of replacing a roll paper.

Application Development Information 89

5.2.1.2 Roll Paper End Sensor

The roll paper end sensor is located in the paper path. It detects the presence of paper through the roll paper in the paper path.

When there is no paper in the path (paper end status), the ERROR LED and the PAPER OUT LED indicator will light and it will be in the error status.

If the sensor detects the roll paper end, the printer will stop printing even in the process of printing. It is recommended that you mainly use the roll paper near-end sensor and use the roll paper end sensor secondarily.

5.2.2 Printer Cover Sensor

5.2.2.1 Roll Paper Cover Open Sensor

The cover-open sensor monitors the roll paper cover. When the sensor detects an open cover while printing, the printer stops printing immediately and automatically goes offline. Depending on the Msw 88 setting, an open cover error is handled as either a recoverable error or unrecoverable error as described below.

❏ Msw 8-8 off: Automatically recoverable error. The ERROR LED flashes. When

the printer cover is closed, the ERROR LED goes off, and the printer goes online and starts printing at the beginning of the line it was printing when the cover was opened.

❏ Msw 8-8 on: (Default) Recoverable error. The ERROR LED flashes. Since the ERROR LED

still flashes after the cover is closed, send the error recovery command to recover from the error.

When the printer recovers, it feeds paper to take up the slack, and starts printing from the beginning of the line where the error occurred. In this case, double printing and printing position shift may occur. It is recommended to set the memory switch Msw 8-8 to ON, clear the printer buffers by a command from the driver, and resend the print data. Whether the cover is open or not does not affect the status reported by the roll paper end sensor.

Note:

When OPOS or Advanced Printer Driver is used, do not change the default setting of the memory switch.

5.2.2.2 Offline

This printer is not equipped with an online/offline switch. The printer goes offline under the following conditions automatically.

• When the power is turned on (including reset using the interface) and while the printer is ready to receive data.

• During the self test.

• When the roll paper cover is open.

• During paper feeding using the FEED button.

90 Application Development Information

TM-L90/TM-L90 Peeler Model Technical Reference Guide

• When the printer stops printing due to a paper-end (in cases when an empty paper supply is detected by roll paper end detector or when it has been set to stop printing by the driver when the roll paper near-end sensor detects a paper end.)

• When an error has occurred.

• During macro executing standby status.

• Waiting for FEED status when inserting the roll paper (to complete the task of inserting the roll paper by pressing the FEED button)

Note:

The off-line status also happens infrequently when the pulse of the drawer kick is sent.

5.2.2.3 Busy state

Selecting conditions that invoke a BUSY State

The conditions that invoke a BUSY condition are selected with memory switch setting mode or memory switch Msw1-3 as follows.

❏ When the receive buffer is full

❏ When the receive buffer is full or the printer is off-line

Note:

In either case indicated above, it will be a BUSY status when turning on the power (including resetting with the interface), while the printer is in the state of receiving data and when executing a self-testing.

You do not need to change this item during the use of OPOS or Advanced Printer Driver.

Application Development Information 91

5.2.2.4 Receive buffer

The capacity of the receive buffer is set using memory switch setting mode or memory switch Msw1-2. The definition of a receive buffer full is described in the following table. The printer ignores the data received when the remaining space in the receive buffer is 0 bytes.

Memory switch Msw1-2

ON 45 bytes From when the remaining space in the receive buffer drops to 16 bytes, to

OFF 4 KB From when the remaining space in the receive buffer drops to 128 bytes, to

Receive buffer capacity

Buffer full definition

when the space increase to 26 bytes.

when the space increase to 256 bytes.

Note:

When using OPOS or Advanced Printer Driver, you don't need to change the receive buffer.

5.2.3 Label Peeling Sensor (Peeler Specification Only)

This detects whether or not there is a peeled label. If a label is removed, the next label is moved to the printing start position.

Note:

If the printer is used in a location with direct sunlight, even when a label is removed, it may be determined as being present due to misdetection, and the printer continues waiting for label removal status. In this case, press the FEED button once to return the paper to the next label printing start position.

5.3 Barcode Printing

The TM-L90 / TM-L90 Peeler Model can print the types of barcode shown below.

5.4 CODE 128 Barcode

The CODE 128 barcode allows a single barcode character to represent one character of a full-ASCII 128character set or two-digit number from among the combinations of 103 different barcode characters and three different code sets.

• Code set A: Can represent ASCII characters 00H to 5FH.

• Code set B: Can represent ASCII characters 20H to 7FH.

• Code set C: One character can represent a two-digit number (100 numbers from 00 to 99).

In addition to the above characters, CODE 128 also provides the following special characters.

• Shift character (SHIFT) The code set A handles the character right after SHIFT as a character of the code set B. The code set B handles the character right after SHIFT as a character of the code set A. SHIFT cannot be used in the code set C.

• Code set selection character (CODE A, CODE B, CODE C) Changes the subsequent code set to A, B or C.

• Function character (FNC1, FNC 2, FNC3, FNC4) The purpose of the function character changes depending on the application. The code set C accepts only FNC1.

5.5 Precautions for Two-Dimensional Code Printing

This printer can print two-dimensional codes. The following two-dimensional codes can be printed.

❏ PDF417

❏ QRCode

❏ MaxiCode

❏ Composite Symbology*

❏ DataMatrix*

*: Available only for TM-L90 4** models

Note the following for two-dimensional code printing.

❏ The two-dimensional code recognition ratio changes depending on the module width, print density,

environmental temperature, roll paper (thermal paper) type, reader performance, etc. Therefore, precheck the recognition ratio and set the operating conditions to satisfy the restrictions of the reader.

❏ For PDF417 (two-dimensional code) printing, it is recommended to set the height of one symbol to

three to five times greater than the module width. It is also recommended to set the overall height of the code to more than 5 mm (approximately).

5.6 NV Memory

NV memory is embedded in the printer. Please use NV memory with attention to the following:

❏ The following restrictions apply when performing nonvolatile memory operations (including data

store and delete).

• The paper feed switch must not be used to feed paper.

• The real time command must not be executed.

• The ASB status will not be sent, even when the ASB function in ESC/POS command is set to enable.

❏ The printer will sometimes enter the Busy state when data is being written to nonvolatile memory. It is

important not to send data from the host computer while the printer is in the Busy state as it will be incapable of processing any received data.

❏ Frequent use of the functions for defining data to and deleting data from nonvolatile memory can

damage the memory. As a rule, in using the various commands to write to NV memory, avoid writing more than an average of 10 times per day.

Application Development Information 97

5.7 FAQ List

The questions shown in the list below begin with "Q" and their replies with "A"

1. Look through sentences beginning with "Q" to find information relating to your question or problem.

2. Then follow the instructions described in the "A" sentence below it.

Q: Print data dropout occurs.

A: Check the handshake process.

Data dropout can occur when the handshake between the host computer and the printer is not performed correctly. This can result in errors related to print buffer capacity.

Confirmation procedure

Use the following steps to check the handshake process.

1. Select a comparatively large volume of data for printing and send it to the printer.

2. Enable the on-line state by opening the printer cover while the printer is printing.

3. Check the data send operation.

• If data send terminates: Handshake process is normal

• If data send continues: Handshake process is abnormal

4. In cases where the handshake process is found to be abnormal, follow the steps listed in Corrective Procedure shown below and re-enter host unit and printer settings so that they match.

Corrective procedure

1. Confirm the serial communication cable. Confirm the specification of cable connection. "Connecting the Cable" on page 63.

2. Confirm serial communication condition. Confirm serial communication condition of printer and host.

Serial communication conditions

•Baud rate

•Parity

•Flow control

•Data length

Confirmation and setting of printer are as follows.

1. Confirm serial communication condition of the printer by self-test (See page 42).

98 Application Development Information

TM-L90/TM-L90 Peeler Model Technical Reference Guide

2. Confirm DIP SW 1-2. Printer serial communication condition can be set by DIP SW and memory switch. When the printer is powered on, DIP SW 1-2 selects DIP SW setting or memory switch setting as initial communication condition. Selected setting is printed by self-test.

DIP SW1-2 OFF: Used communication condition set by memory switch.

ON: Used communication condition set by DIP SW.

3. Set communication condition When DIP SW1-2 is ON Follow the procedure (page 40) and set.

When DIP SW1-2 is OFF Follow the serial communication conditions (page 42). There are two ways to set it. Refer to "Memory Switch Settings" on page 42 or "Memory Switch Setting Utility" on page 89.

Note:

TM-L90 4** models or TM-L90 Peeler 39* models do not have the DIP switches; however, various functions can be set with memory switches. For detailed information about the memory switches, see "Memory Switch Settings" on page 42.

Q: Drawer Kick does not operate properly.

A: Drawer specifications differ depending on the manufacturer and the part number.

Refer to "Connecting the Cash Drawer" on page 72 and check that the cash drawer meets the required specifications.

Q: Unable to print a part of Page 0 (for example ) in Visual Basic.

A: When programming with Visual Basic, limitations prevent data from 81h through 9Fh and E0h through FEh from being sent as characters. However, you can use the following procedure to send this data.

Dim Send_ data(0) As Byte Send_data(0) = &h81 ’1 byte of sending data MSComm1.Output = Send_data

Q: Does USB 2.0-compatible equipment accept the USB interface printer?

A: Yes, but note that the speed of communication between the USB2.0 equipment and the printer is “USB full speed mode.”

Note:

USB2.0 defines three speeds: High speed (480 Mbps), Full speed (12 Mbps) and Low speed (1.5 Mbps). This printer supports only Full speed (12 Mbps) and Low speed (1.5 Mbps).
