Chapter 2 Setup

Changing the Paper Width

The printer is initially set to print on 80 mm width paper and you can change the printer to print

on 58 mm width paper by installing the roll paper guide and changing the paper width setting

with the customized value.

Follow the steps below to install the roll paper guide.

Once you change the paper width from 80 mm to 58 mm, you cannot change it back to 80 mm.

To set the customized value, see "Setting the Memory Switches (Customized Value)" on

page 63.

Open the roll paper cover.

Install the roll paper guide so that the projection on its bottom is aligned

with the hole at the right of the roll paper holder.

Hole

Tighten the enclosed screw to fix the roll paper guide.

Paste the enclosed 2 small strips along the roll paper guide on the

bottom of the roll paper holder.

Make sure the space between the top edge of the strip and the line of the groove in the roll paper guide is 0.5 mm or less.

Adjusting the Paper Roll Near-End Sensor

Below are two situations where a roll paper NE sensor adjustment is required.

• To adjust the detection position to suit the diameter of the roll paper core used.

• To adjust the detection position of remaining amount of paper.

• Since roll paper cores vary slightly in shape, depending on paper roll design and manufacturing tolerances, it is impossible to detect the remaining paper exactly.

• Use roll paper with a core inner diameter of 12 mm {0.47"} and outer diameter of 18 mm {0.71"} so that the NE sensor can detect the remaining paper as accurately as possible.

Follow the steps below to adjust the roll paper near-end detector.

Open the roll paper cover, and remove the roll paper.

Loosen the adjustment screw fastening the sensor, and align the upper

edge of the positioning plate with the adjustment position.

Chapter 6 Replacement of the TM-T88IV

Replacement of the TM-T88IV

The TM-T88V is designed so that it can smoothly replace the TM-T88IV. This chapter describes

precautions for the replacement.

Compatibility

Printing

The printing and character specifications are the same as those of the TM-T88IV. Without special

configurations, the TM-T88V prints the same results as the TM-T88IV prints.

Print Density

The print density of the TM-T88V can be set with DIP switches (2-3/2-4) as can the TM-T88IV.

Set the density the same as for the TM-T88IV to print in the same print density.

The print density can be set also with a customized value. The default setting of the customized value is “Depends on the DIP switch settings.” If the customized value is changed, the value set with the customized value is enabled. (See "Setting the Memory

Switches (Customized Value)" on page 63.)

Two-Color Printing

You cannot use the paper for two-color printing (P320RB/P320BB) with the TM-T88V, which you

can use with the TM-T88IV.

Number of Head Energizing Parts

For the TM-T88V, the default setting of the number of head energizing parts is “One-part

energizing.” You can change the setting with the customized value (See "Setting the Memory

Switches (Customized Value)" on page 63.); however it does not usually need to be changed.

Number of head energizing part

TM-T88V TM-T88IV

• One-part energizing

• Two-part energizing

• Four-part energizing

• One-part energizing

• Two-part energizing

• Four-part energizing

• Auto energizing

Printable Area (for 80 mm Width Paper)

The printable area (left/right margins, print start position from the autocutting position, print

start position from the manual cutting position) of the TM-T88V is the same as that of the

TM-T88IV.

Cutting Method

The TM-T88V uses the partial cutting method (cutting with one point in left edge left uncut) as

does the TM-T88IV.

Manual Paper Feed

Manual paper feed is not possible with the TM-T88V while it is possible with the TM-T88IV after

printing pauses.

Receive Buffer

You can set the receive buffer of the TM-T88V to 4KB or 45 bytes with DIP switch 1-2 as with the

TM-T88IV. The buffer full condition and buffer full release condition of the TM-T88V are the

same as those of the TM-T88IV.

Memory Capacity

The sizes of the download buffer and NV graphics data of the TM-T88V are the same as those of

the TM-T88IV.

Electrical Characteristics

The operating voltage of the TM-T88V is DC24 ± 7%, the same as the TM-T88IV. The current

consumption differs, depending on the print duty.

The TM-T88V does not have a low power consumption mode, which the TM-T88IV has, so you cannot set DIP switches 2-3 and 2-4 to on. Use the newly added low power load mode instead.

Chapter 6 Replacement of the TM-T88IV

DIP Switches

The functional assignments of DIP switches are the same as those of the TM-T88IV except for

DIP switches 2-3 and 2-4.

Since the TM-T88V does not have a low power consumption mode, do not set DIP switches 2-3

and 2-4 both to ON.

Printer Status

The TM-T88V goes to the same status under the same conditions as the TM-T88IV. You can

replace the TM-T88V with the TM-T88IV without modifying applications.

Logo Registration

The TM-T88V can register logos in the NV memory (NVRAM) with the TM-T88V Utility, while

the TM-T88IV can register logos with the TM Flash LOGO Setup Utility for NVRAM (TM-Flogo).

For detailed information about the TM-T88V Utility, see the TM-T88V Utility User’s Manual.

Driver Compatibility

You can operate the TM-T88V with a driver for the TM-T88IV or the TM-T88III.

You cannot operate the TM-T88IV with a driver for the TM-T88V.

Advanced Printer Driver

When the TM-T88IV was controlled by APD Ver. 4.00 ~ 4.04, you need to change the TM-T88V

printer model name to “TM-T88IV” using the customized value. (See "Setting the Memory

Switches (Customized Value)" on page 63.)

When the TM-T88IV was controlled by an APD other than Ver. 4.00 ~ 4.04, you can replace it

with the TM-T88V without modifying the APD.

OPOS ADK

If the TM-T88IV was controlled by an OPOS ADK, you can replace it with the TM-T88V without

modifying the OPOS ADK.

USB Low Power Consumption Mode

With the TM-T88V, you can enable the USB low power consumption mode with DIP Switch 1-8,

just as you can with the TM-T88IV. (See "For Ethernet/Wireless LAN/USB Interface" on page

60.)

Maintenance Counter

The TM-T88V has a maintenance counter just as the TM-T88IV has.

Buzzer

TM-T88V is available with a built-in buzzer or without the buzzer. Even if you purchase the one

without the buzzer, you can attach an optional external buzzer. You can beep the buzzer with the

pulse signal using a command. (See "Setting the Built-in Buzzer (for Model with a Built-in

Buzzer)" on page 42, "Connecting the Optional External Buzzer" on page 43.)

For detailed information about ESC/POS commands, see the ESC/POS Application Programming Guide.
