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.

The ink is not harmful to the human body, but contains some organic solvents. Black, cyan, magenta, photo cyan, and photo magenta ink contain glycerin 56-81-5, isopropyl alcohol 67-63-0, ethylene glycol 107-21-1, and di-ethylene glycol 111-46-6 respectively. Yellow ink contains glycerin 5681-5 and isopropyl alcohol 67-63-0. Be careful not to get the ink into your mouth or eyes. If the ink gets into your eyes, wash with plenty of water and consult a doctor. In case a large amount of ink has been swallowed, consult a doctor immediately. The ink contains dyes. If clothing is stained with the ink, the ink may not be removed completely.

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. Carefully wipe off the ink mist with a soft dampened cloth so that hands or clothing will not be stained by soiled parts during servicing. Also, be careful not to smudge the pick roller when removing the upper cover.

2.2.3 Precautions for damage due to static electricity

Static electricity can be generated by clothing rubbing against each other and may accumulate in the body. If you touch electrical elements, the discharge of static electricity could damage them, or change their electrical characteristics. For this reason, avoid touching the ink sensor contacts or the printer's BJ cartridge contacts.

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. Remove the ink tanks and keep them in a vinyl bag while the printer is being transported.

2.2.5 Precautions on spur tip deformation

Take care not to bend the tips of the spurs. The tips of the spurs make contact with printed paper and are contaminated with ink, but due to their small surface contact area, the tips, cleaned by the spur cleaners, will not stain the printed paper. However, if the tips are bent and their contact surface area increases, they collect more ink and are not easily cleaned by the spur cleaners, and thereby stain the printed paper by making dotted lines on it.

2.3 Precautions for Disassembling and Reassembling the Printer

Note the following when disassembling or reassembling the printer. When disassembling or reassembling the printer, refer to the parts catalog. The numbers in the parts catalog illustrations indicate the disassembly sequence.

2.3.1 Unlocking the carriage

When the printer is shipped from the factory (or when the cartridge is installed and the power has been turned off normally), the carriage is locked in the capping position to secure the cartridge during transportation. When the printer is powered on properly, the carriage is unlocked automatically. If the printer cannot be powered on normally, it will be necessary to manually unlock the carriage. This can be done by turning the gear of the purge unit in the direction of the arrow by finger, as shown in Figure 2-5 Unlocking the Carriage.

2.3.2 Removing/installing self tap screws

The printer unit is secured to the lower case with tap screws. Once the tap screws have been removed, pieces of the molding remain attached to the screw threads. Reinstalling the tap screws in this condition can damage the screw threads. To prevent this, when reinstalling screws, remove the remains in advance or, where possible, use new screws. Also, blow away any remains on the mold before reinstalling the tap screws.

Part 2: MAINTENANCE

BJC-8200

Figure 2-5 Unlocking the Carriage

2.3.3 Adjustable bushings supporting the carriage shaft

The adjustable bushings supporting the carriage shaft are adjusted and secured to the printer frame so that the ideal gap, or head gap, between the BJ cartridge nozzle and platen is maintained for best print quality. The fixing screws are painted red to protect against careless removal. Do not loosen the fixing screws.

2.3.4 Feed gear
