1 Correction of Section “6.5 End of Paper Detector”
This section has been corrected as shown below:
6.5 End of Paper Detector
The printer uses a mechanical switch for detecting paper out with continuous or single sheet paper. When paper is loaded in the
printer, the lever is down, and the condition of the mechanical switch is on. This sends a signal to the CPU indicating paper loaded
in the printer. When paper is out, the lever is up, and the condition of the mechanical switch is off. This removes the signal from
the CPU indicating no paper is in the printer.
2 Correction of Section “8.2.5 Carriage Motor Drive Block”
The schematic diagram in the section 8.2.5 Carriage Motor Drive Block has been corrected as shown below. Replace the original
