T80P Operator's Manual

(2) 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 particularly affected by this.

Notes on the power supply

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

supply connector.

• Be sure you don’t 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 flucuates more than this, print

quality will be poor.

Notes on handling the printer mechanism

• Don’t turn the paper-feed knob while the print head is down.

• Don’t pull paper out (forward/backward directions) while the print

head is down.

• The thermal elements of the head and driver IC are easily damaged;

avoid touching them with anything made If metal.

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

during and just after printing; don’t touch directly with your fingers.

• Operate the head-open lever only when necessary.

• Don’t touch the surface of the head’s thermal elements directly with

your fingers. (Dust and dirt can stick to the surface and affect the

thermal elements .)

• Thermal paper containing Na

, K

–

, and Cl

ions will affect the head’s

thermal elements. Be sure to use only the paper specified.

• Label paper cannot be used.

Notes on paper cutting

Roll paper may be pulled out slightly when paper is manually cut.

Dots may have a squeezed appearance in the vertical direction after

cutting.

To prevent this, feed paper for 12 steps (6 dots) or more before printing.
