When the print signal is active, this transistor turns on. Differences in thickness within printing area must be less than 0. Remove the two screws CPS M3X8 securing the paper tension assembly to the right and left frames, and remove the paper tension assembly. No current It2 flows to coil T3io-i2, and the energy 6 ‘ accumulated in choke coil L4 is output rectified by D , smoothed by C31, C32, and C33, and output. At this time, make sure that the platen gap gear does not move. Cable Remove the printer mechanism.
