    BJC-8200 Part 2: MAINTENANCE 2.2 Operation Precautions 2.2.1 Ink paths Be careful not to touch the ink paths. Ink on hands could stain the printer, work table, or clothes. The ink paths include the BJ cartridge ink tank outlet, the BJ cartridge ink filters and nozzles, the maintenance jet receiving section, the head caps, the wipers, and the waste ink absorber.

  • Page 26: Ink Mist

    Part 2: MAINTENANCE BJC-8200 2.2.2 Ink mist The BJ cartridge ejects ink onto the paper during printing. After the printer is used for a long period or used heavily, the ink mist bouncing back from the paper could accumulate and soil the front cover, platen, and the area around the operation panel, purge unit, and paper output tray.

  • Page 27: Precautions For Transporting The Printer

    BJC-8200 Part 2: MAINTENANCE 2.2.4 Precautions for transporting the printer When turned off by the POWER button, the BJ cartridge is capped and the carriage is locked in place at the capping position by the lock arm. When the printer cannot be powered off by the POWER button for transportation, etc., move the carriage to the capping position by hand and secure it with tape before transporting the printer.

The ASF, driven by the paper feed motor, feeds paper automatically.

  • Page 78: Carriage Function

    Part 5: REFERENCE BJC-8200 1.2 Carriage Function The carriage of this printer is moved back and forth horizontally by the carriage belt, which is driven by the carriage motor, a DC motor. This printer has no sensor to detect the carriage's home position. The encoder sensor, mounted on the carriage board, enables control of the carriage position by reading data from the encoder film, assuming the initial position being where the carriage contacts the right hand interior wall of the printer.

  • Page 79: Purge Unit Functions

    BJC-8200 Part 5: REFERENCE 1.3 Purge Unit Functions The purge unit, using the built-in purge motor, carries out the following operations: head-capping, head-wiping, ink-suction, and ASF-driving. The purge unit switches over the drive for these operations by reversing the direction of motor rotation, and also by using the drive selector lever.
