CAUTION:
Wear a grounded wrist band when handling the internal circuit boards to prevent
damage from static electricity.
When removing an internal circuit board, place it on an anti-static rubber sheet or
similar surface to prevent damage from static electricity.
Parts on the circuit board may become hot during operation. Therefore, wait
approximately 10 minutes after turning the power off before touching them.
Be careful not to subject the circuit boards to shock or vibration, because this may
damage them.
Do not touch the circuit board or cable terminals with your hands to prevent
contamination that may result in a malfunction.
Do not use an alcohol, benzine, thinner, trichloroethylene, or ketone-based solvent to
clean the parts. This type of solvent may damage the plastic and rubber parts.
Wipe off any dirt with a dry or slightly moist cloth. Be sure to remove the power cord
from the outlet at this time.
Note that the print head and the paper feed motors become very hot during normal
operation, creating the danger of burn injury. Be sure to wait for about 10 minutes after
turning printer power off before begining the maintenance, repair, or inspection.
