BJC-7100

Part 4: Technical Reference

2) Wiper

After the purge operation, the rotation of the purge drive gear is switched so that, when the cap lowers, wiping is performed. The wiper of the BJC-7100 printer's purge unit operates in the direction of the rows of nozzles to wipe any ink from the head face plate.

The ink removed by the wiper from the head face plate is absorbed by the cleaner unit on the back face of the platen chassis and the cleaner on the cap unit.

In addition to vertical wiping by the purge unit, there is an additional wiper on the left of the printer for the ink optimizer head. This special wiper operates horizontally in relation to the rows of nozzles.

The wiper for the ink optimizer head is operated by the carriage travelling back and forth. The effect of removing ink optimizer and ink aggregates is improved by combining the operations of the purge unit wiper and the wiper for the ink optimizer head.

3) Caps

The purge unit of the BJC-7100 printer has four caps: two for ink purging and capping, and two for capping only.

After the carriage moves to the capping position, the caps are pressed against the print head faces.

The two caps for ink absorption and capping are attached to the pump and purge ink from the BJ cartridge in the cleaning operation.

The purged ink is sent to the ink absorber on the bottom cover unit.

After the ink has been purged, the carriage moves to the left of the capping position to absorb any waste ink stuck in the cap. So that this waste ink does not mix in the waste ink absorber with the ink optimizer and form aggregates, the absorber is equipped with a wall to separate the ink and ink optimizer.

4) Pump

The pump is a tube pump in which a rotating roller is pressed against the ink tube to create a negative pressure so that the ink is purged. The ink and ink optimizer ink tubes are, respectively, attached to the caps.

5) Slide lock lever

The slide lock lever is linked to the transmission arm and switches the power from the paper feed motor.

After the carriage moves further to the right of the capping position, the hook on the back of the carriage slides the slide lock lever to the right to release the transmission arm lock. Depending on the direction of rotation of the paper feed motor when the transmission arm lock is released, the driving force of the transmission arm gear drives either the purge unit or the sheet feeder.

6) Carriage lock lever

The carriage lock lever is unified with the cap unit and locks the carriage in the capping position to prevent it from moving horizontally when the caps are pressed against the faces of the print heads.
