Troubleshooting Procedure Table lists the troubleshooting tools contained in the printer. The potential at point becomes higher than that at point a , and the energy accumulated in C 11 is released to keep Ib flowing to Q1. A standard front push tractor and straight paper path load up to 6-part forms with zero tear-off for zero waste, zero skewing and zero jams.

Therefore, voltage V 1jn across coil T Surge Voltage Absorbing Circuit When a phase driver changes from on to off, a surge voltage is induced due to reactance in the motor coil. Platen Gap [mm] 0.

Remove the nut HNO M4 securing the side frame support to the left frame. Remove the platen paper guide by turning it toward you.

The main optional interfaces are listed in Table If the paper runs out, the PE sensor detects it Refer to Figures and 5. Path of Sensor Lead Wires Figure Refer to Table A in Appendix for details.

But the paper feed accuracy can not be assured in the area approx. Remove the E-ring RE 8 from the platen shaft at the left frame side. Surge current that flows when the printer power is first turned on is suppressed by the 22250 suppression circuit. A condensed mode for 15 CPI characters is not available.

Connector Descriptions Table Printing Mechanism Figure shows the printing mechanism. When the power supply for the control circuits starts operating normally, voltage is induced in the epsob side of transformer T2. VR 1 is used for bidirectional printing in the LQ mode, and VR2 is used for bidirectional printing in the draft mode. The values are for when CN2 is disconnected.

The adjusted position is stored in the memory and remains effective at the next tear-off even if the power is turned off and on. At this time, make sure that the platen gap gear does not move. Move the carriage to the left. If single sheet paper is loaded, the paper is ejected forward and the fanfold paper is loaded.
