Read the following warnings before assembly or disassembly.
Because this printer weighs 30 Kg and is much larger and heavier than existing models, careful
attention should be paid when handling it. It must be carried by two or more persons, supporting
it from the bottom as shown in Figure 3-1. Never lift it by holding the front cover because the front
cover could come off.
Before disassembling, assembling, and adjusting the printer, be sure to disconnect the AC power
cord.
The main board of the printer is equipped with a lithium battery. Before disassembling the main
board, read the following cautions so that you can handle the battery safely. Also be careful of
its storage condition.
a. Do not store lithium batteries stacked together or with other metal parts, to prevent the + and
– sides from making electrical contact, which could cause a short circuit.
(If a battery is shorted, a large current can flow. The battery could ignite or
heat generated.)
b. Do not heat the battery. Do not throw it away into a fire.
c. Do not solder any portion other than the connection terminals.
(The battery might burn or burst if the internal solution leaks out or if it shorts internally. If the
solution in the battery leaks and it is left as it is for a long time, the printer components around
the battery could be damaged.)
d. Do not charge the battery.
(If it is charged, gas would be generated, and it could ignite or burst.)
e. Do not disassemble the battery, or deform it using pressure.
(The gas in the battery could irritate your throat, or the battery might
burst or ignite, and the solution might leak.)
f.
Do not mount the battlery (+ and – sides reversed).
(If the + and –-sides are reversed, the battery might ignite or burst due to a short circuit.)
The printhead reaches very high temperatures, and if you place your hand on it, it could burn you.
Always be sure that the printhead is cool when you handle it.
The power cord and interface cable must be disconnected before moving the printer.
Because the components are larger and heavier than those of previous models, wear gloves to
protect your hands when handling the DFX-8000.
