When the printer goes to the standby (data-waiting) state during printing, the

printer stops printing and feeding paper temporarily. When the printer restarts,

the paper may shift 1 to 3 dots at the start of printing. Graphics printing is

especially affected by this.

Notes on the power supply

l Turn the external power supply on after connecting it to the power supply

connector.

Be sure you do not connect the external power supply with the wrong polarity.

If it is connected incorrectly, the internal circuit fuse may blow or the external

power supply may be damaged.

The power supply voltage should be 24 VDC ±7%. The voltage fluctuation

between no-load and printing should be ±2% or less. If the power supply

voltage fluctuates more than this, print quality will be poor.

Notes on handling the printer mechanism

Do not pull paper out (forward/backward directions) while the print head is

down.

The thermal elements of the head and driver IC are liable to be damaged;

avoid touching them with anything made of metal.

The areas around the print head and motor surface are very hot during and

just after printing; do not touch directly with your fingers.

Do not operate the head-open lever except when necessary.

l Do not touch the surface of the head thermal elements directly with your

fingers.

(Dust and dirt can stick to the surface, which will affect the thermal

elements.)

Thermal paper containing Na¯, K¯, and Cl¯ ions will affect the head thermal

elements. Be sure to use only the paper specified.

Notes on handling thermal paper and label paper

Notes on using thermal paper

Chemicals and oil that come into contact with the thermal paper may cause

discoloration, and can also cause the printing to fade.

Therefore, pay attention to the following:

Use water-based paste, starch paste, polyvinyl paste, or CMC paste when

gluing thermal paper.

b) Volatile organic solvents such as alcohol, ester, and ketone can cause

discoloration.

Some adhesive tapes may cause discoloration, and may also cause the

printed image to fade.
