(2)Print transfer

The planetary gear turns clockwise and is disconnected from the PU gear,so that the paper is not fed automati cally. In case of hand paper feed the paper is fed directly to the transfer roller.

9. Carriage Motor PRINTER FEED GEAR

The ASIC controls the carriage motor, which is a stepping motor that connects via a 4-pin connector to CN2 on the printer PWB.

10. INK Cartridge Carriage

The carriage connects via a flex circuit that plugs into the 32 pin connectors, CN3 and CN4 on the printer PWB. The ink cartridge contacts connect to the carriage contacts.

The ASIC controls the carriage , and ink cartridge.

11. Paper IN Sensor

The Peper-IN-Sensor exists on printer PWB.

This sensor is an optical sensor.If the optical route is interrupted,Collector PIN(pin-C)of this sensor indicates Hi- Level(5V).If the optical route is opend,pin-C indicates Low-Level(0V).

This sensor provides information of front and end edge location of recording paper and information of paper jam. The change between Hi and Low of this sensor(PC1 pin-C)is used as follows.

1. In the case of manual paper feeds

When the recording paper is inserted from By-pass route,the front edge of this recording paper pushes the lever,and this sensor indicates L.

Paper feed action is happened by this change and recording paper is fed in constant length.

As paper feeds out of paper path,the lever returns,this sensor indicates H and provides information of end edge of the recording paper.

2. In the case of auto paper feeds

When printing action happens and there is no recording paper at By-pass route and there are some recording papers at auto paper providing unit,the feed motor is driven and the recording paper is fed from auto paper provid- ing unit.

At this time,the change from H to L of this sensor provides the front edge of the recording paper.And this sensor provides information of paper jam ,when this sensor DOES NOT change from H to L after some time.

As paper feeds out of paper path,the lever returns,this sensor indicates H from L and provides the infomation of end edge of the recording paper.
