5. Service Tables
Service Program Mode
• Before calling for service, first, confirm that there is no print data in the printer buffer (the Data-in LED
should not be lit or blinking). If the LED is blinking, this means there is data in the buffer. Wait until all
data has been printed.
Service Program Mode: Overview
Entering the Service Mode
There are two ways to enter the service mode.
Method 1: Fast Start (Power Off)
Use this method to open the SP mode when you are turning the machine’s power on. This method bypasses
the warm-up time.
1. Hold down [Suspend/Resume] and [Escape] together, then turn the machine on.
2. Hold down both keys until “1. Service Menu” appears on the display.
Method 2: Normal Start (Power On)
Use this method to enter the SP mode with the machine on.
