Ribbon Advance Mechanism

The ribbon is held between the ribbon advance roller ribbon driven gear and the ribbon pressure roller. When the carriage moves from left to right and vice versa on the CR guide shaft, the timing belt turns the belt-driven pulley. Then the torque is transmitted to the ribbon driving gear through the gear trains. The ribbon driving gear rotates counterclockwise, no matter what direction the carriage moves, because a planetary gear is used in the gear linkage. Table 2-4. Ribbon Advance Gear...

Removing the PW Sensor Assembly

1. Remove the printer cover and ribbon cartridge see Section 3.2.1 . 2. Remove the CB screw 2.5 x 5, F Zn securing the PW sensor to the ribbon mask holder. Then, remove the FFC from the PW sensor connector, mounted onto the CR cover. 3. Remove the PW sensor assembly along with the CR cover by pushing and releasing the 2 clips for the CR cover, as shown in the following figure.

TPE Level Reset

This section describes the procedure to reset the TPE top paper end level. This operation is required when the PW sensor assembly is replaced, and if it is not performed, the printer does not recognize that the PW sensor has been replaced, thus, limiting the ability of the new sensor to operate. This reset operation can be performed only from the Settings Diskette. Note After this operation, the reset value for the TPE LEVEL is printed out automatically. Check that the reset value is FF. 1....

System Reset Circuit

Control circuits IC1 and IC2 are initialized when a RESET signal LOW level is output from port 1 VOUT of IC10. IC10 monitors the 5 V line on port 3, and resets under the following conditions 1. When the power supply is turned on, a RESET signal is output. RESET is canceled when the 5 V line goes up to 4.2 V, and then 100 ms passes. 2. When the 5 V line goes below 4.2 V, a RESET signal is output. RESET is canceled when the 5 V line goes back up to 4.2 V and then 100 ms passes. 2. When the 5 V...
