LED Display
When an error occurs, the Status LED lights up or blinks (depending on the error type) as follows.
1. No Error Detected:
• Standby
The printer is online and awaiting printing data.
• Initialization
Initialize printer memories. The printer goes offline during initialization. Once initialization is
complete, the printer goes into standby mode.
• Status of Waiting Error Cancellation
Printer changes to this status during certain error conditions (e.g., paper empty, paper cover
open, etc.). Offline status and Status LED remain its status. Printer goes into standby mode
when FEED button is pressed.
2. Error Detected:
• Temperature Error
The print head temperature is increased by continuous, heavy-duty printing. If the print head
temperature exceeds 70°C, operation of the print head is automatically stopped to prevent
overheating. The printer goes offline and resumes printing only when the temperature of the
print head returns to 60°C or below.
• Paper Empty
When the printer detects that paper roll has reached the end, the Status LED lights up and
the printer goes offline.
• Paper Cover Open
When the paper cover is open, the Status LED lights up and the printer goes offline.
