General Precautions

• When peeling a DK Die-cut Label, some portion of the label may remain. Remove the remaining 

portion before attaching a new label.

• Do not drop the DK Roll, or damage to the DK Roll could result.
• Do not use CD/DVD labels in a slot loading CD/DVD player, for example a CD player in a car 

where the CD is slid into a slot in the CD player.

• Do not peel off the CD/DVD label once it is applied to the CD/DVD.

A thin surface layer may come off, resulting in damage to the disk.

• When applying CD/DVD labels, use the applicator included with the CD/DVD label rolls. Do not use 

a disk if the labels are not properly applied. Doing so could cause damage to the CD/DVD player.

• Be sure follow the instructions in your CD/DVD player's instruction manual regarding applying CD/

DVD labels.

• User's shall take full responsibility for applying CD/DVD labels. Brother accepts no responsibility 

for any loss or damage of data caused by the inappropriate use of CD/DVD labels.

• Do not apply CD/DVD labels to CD/DVD disks designed for use with ink jet printers. Labels peel 

off of these disks easily, and using disks with peeled labels can result in loss or damage of data.

• Be careful when handling the DK Roll.

Dropping the roll may break the spool and make it unusable.

• Some DK rolls use permanent adhesive for their labels. These labels cannot be neatly peeled off 

once attached.

CD-ROM & Software

• Do not scratch the CD-ROM.
• Do not subject the CD-ROM to extremely high or extremely low temperatures.
• Do not put heavy objects on the CD-ROM or apply force to the CD-ROM.
• The software contained on the CD-ROM is meant for use with the QL-500/550 only. See License 

on CD for further details. This software may be installed on multiple personal computers for use 
at an office, etc.

AC power cord

• Use only the AC power cord included with the QL-500/550.
• If the QL-500/550 will not be used for an extended period, remove the power supply cord from the 

electrical outlet.

• Always hold the plug when removing the power cord from or inserting it into the outlet. Pulling on 

the cord could cause a problem with the power cord.

• The standard electrical outlet shall be installed near the QL-500/550 and shall be easily accessible.

Cutter unit

• To prevent injury from the broken cutter blade and 

unit, follow these points: 
Close the top cover when operating the cutter unit. 
Don’t apply excessive pressure to the cutter unit. 
When the cutter blade becomes dull, replace the 
existing cutter unit with a new one. If the cutter blade 
should break off, unplug the power cord from the 
electrical outlet and remove the cutter unit carefully 
with tweezers so you do not touch the blade.  

• If a paper jam should occur due to a build up of 

adhesive on the paper guide surface, unplug the 
power cord from the electrical outlet and wipe away 
the adhesive buildup on the paper guide surface 
with a cloth dipped in ethanol or isopropyl 
(rubbing)alcohol.  It is recommended that you clean 
the paper guide when replacing the cutter unit. 

• The average number of cuts is 5,000 or more 

depending on the operating environment.  Dull cut, the inability to cut straight, or frequent paper 
jams may indicate that the cutter life is near the end.  Replace the cutter if these conditions occur.
