Introduction

With your PT-90, you can create labels for any application. 

Select from the many frames, character sizes and styles to 

design beautiful custom labels. In addition, the variety of 

tape cartridges available allows you to print labels with 

different widths and exciting colours.

Read this manual carefully before starting and keep the 

manual in a handy place for future reference.

The contents of this guide and the specifications of this 

product are subject to change without notice.

Safety Precautions

 Warning

Follow these guidelines to avoid the risk of fire, burn, 
injury, electric shock, damage, overheating, abnormal 
odours or smoking.

• Always use the specified voltage and the suggested AC adapter 

(AD-24ES) for this machine to prevent any damage or failure.

• Unplug the adapter cord immediately and stop using the P-touch  

during an electrical storm.

• Do not use the machine/AC adapter in places of high humidity such 

as bathrooms.

• Do not overload the adapter cord.

• Do not place heavy objects on, or damage the adapter cord or plug. 

Do not forcibly bend or pull the adapter cord. When disconnecting 

the adapter cord from the power outlet, always hold the plug.

• Make sure that the plug is fully inserted in the power outlet. Do not 

use an outlet that is loose.

• Do not swallow the cutter stopper.

• Do not get the machine/AC adapter/adapter plug wet, such as by 

handling them with wet hands or spilling liquids on to them.

• Do not disassemble or modify the P-touch/AC adapter/batteries.

• Do not use metallic objects, such as tweezers or a metallic pen, 

when changing the batteries.

• Do not throw the batteries into fire or expose to heat.

• Disconnect the AC adapter, remove batteries immediately and stop 

using the machine if you notice abnormal odour, heat, 

discolouration, deformation or anything unusual while using or 

storing it.

 Caution

Follow these guidelines to avoid personal injury, 
battery leakage, burn and heat.

• Do not touch the cutter blade near the print head.

• Remove the batteries and disconnect the AC adapter if you do not 

intend to use the P-touch for an extended period of time.

• Do not use old and new batteries together or mix alkaline batteries 

with other type batteries, or set the positive and negative end in the 

wrong position. 

• Do not drop or hit the P-touch/AC adapter.

• Do not press hard on the LCD display.

• Make sure you do not trap your fingers when closing the cassette 

cover.

General Precautions

• Depending on the location, material, and environmental conditions, 

the label may unpeel or become irremovable, the colour of the label 

may change or be transferred to other objects. Before applying the 

label, check the environmental condition and the material.

• Do not use the P-touch in any way or for any purpose not described 

in this guide. Doing so may result in accidents or damage to the 

machine.

• Use only Brother M tapes with this machine. Do not use tapes that 

do not have the 

 mark.

• Only use a soft, dry cloth to clean the machine; never use alcohol 

or other organic solvents.

• Use a cotton swab to clean the print head; never touch the print 

head.

• Do not put any foreign objects into the tape exit slot or AC adapter 

connector, etc.

• Do not place the P-touch/battery/adapter in direct sunlight or rain, 

near heaters or other hot appliances, in any location exposed to 

extremely high or low temperatures (e.g. on the dashboard or in the 

back of your car), high humidity, or dusty locations.

• Do not apply excessive pressure to the cutter lever.

• Do not try to print if the cassette is empty; it will damage the print 

head.

• Do not pull the tape while printing or feeding; it will damage the tape 

and machine.

• When power is disconnected for more than three minutes, all texts 

settings and any text files stored in the memory will be cleared.

• Any data stored in memory will be lost due to failure or repair of the 

P-touch, or if the battery expires and no adapter is connected.

Power Supply and Tape Cassette

Changeable Faceplates

The PT-90 comes with a variety of different faceplates - enabling users to customize the machine. To change the faceplates, follow the steps below.

Remove the cassette cover by pressing the 

above indicated area.

If a tape cassette is already installed, remove it by 

pulling it straight up. Also, if batteries are already 

installed, remove them.
• Make sure that the power is turned off when 

replacing batteries or tape cassettes.

Insert four new AAA alkaline batteries 

(LR03), making sure that their poles point in 

the correct directions.

• Always replace all four batteries at the same time 

using brand new ones.

• For using optional AC adapter (AD-24ES), refer to 

“Using Optional AC Adapter”.

Insert a tape cassette, making sure that it 

snaps into place.

• Make sure that the end of the tape feeds under the 

tape guide.

• Use only Brother M tapes with this machine.

Insert the two hooks at the bottom of the 

cassette cover into the slots on the machine 

(

1

), and then close the cover securely until 

it snaps into place (

2

).

After you have installed the tape, feed the tape (see 

“Feeding”) once and then push in the tape cutter lever 

to cut the tape.

Remove the cassette cover by pressing the 

above indicated area. Slide the front cover 

back and lift up from machine.

• Make sure that the power is turned off when 

replacing the faceplate.

Remove the inserted faceplate, and then 

replace it with another one.

• Be sure to remove the protective film from the front 

side of the faceplate before replacing.

• Do not insert more than one faceplate at a time. This 

can damage the faceplates and cause the front 

cover to fit incorrectly.

Insert the hooks on the front cover into the 

slots on the machine, and slide the cover 

back into place.

Insert the two hooks at the bottom of the 

cassette cover into the slots on the machine 

(

), and then close the cover securely until 

it snaps into place (
