Now the paper path is relieved and you can remove any stuck ticket, and clean the
printhead.
CAUTION! – The printhead is very sensitive to static electricity and to scratches. NEVER
use any tool on the printhead. To clean it, use a soft piece of cloth and pure isopropyl
alcohol.
5.3 Self test
1. Press and hold the front pushbutton at power ON to enter self-test mode.
2. Press again to encode and print one ticket. The printout shows current firmware ver-
sion.

The green indicator lights up at power ON. Should it fail to light up, switch the TTPM2

both in the TTPM2 and in the wall outlet. Also check your main power supply fuse.
