Handling of The Machine
z z z z Do not turn off the Main Power Switch or unplug the electrical (power) cord during operation.
z z z z Do not open any covers during operation.
z z z z Do not move the machine.
z z z z The machine has precision parts and driving parts inside. Do not handle the machine in other ways than described in this
manual.
z z z z Contact your service representative before moving the machine.
z z z z Do not place heavy objects on or apply shocks to the machine.
z z z z Be sure to open and close any cover gently.
z z z z When turning off the Main Power Switch of the machine and then turning it on again, wait more than 10 seconds before turning
it on.
z z z z If the machine will not be used or has not been used for a long time, be sure to perform Ink Head Maintenance (normal
cleaning). Otherwise, deterioration or drying of ink occurs in the ink transfer path inside the machine, resulting in clogging at
the head. To prevent this problem, periodic use is recommended.
z z z z Never touch the print head because a failure or deterioration of images may occur.
z z z z Be sure to use always the machine with the four ink cartridges mounted. Even if some ink cartridge is not used, do not leave
the machine with an ink cartridge removed.
Handling and Storage of Ink Cartridge
z z z z Do not shake the Ink Cartridge before use. Air bubbles may occur, resulting in defective printing.
z z z z Do not add ink into the Ink Cartridge.
z z z z If ink remains for a long time after the cartridge is opened, the ink may be deteriorated because of various components
contained in the air. Use of deteriorated ink may cause a failure of the print head or the ink transfer path.
z z z z The injection characteristic of the ink jet printer varies with viscosity of the ink. At a low temperature, particularly, the
viscosity increases and clogging of the print head may occur. Observe the operation environment and storage temperature, and
use the ink earlier checking the date of manufacture.
z z z z The adequate operation temperature of the machine is 15°C - 30°C (59°F to 86°F) Use of the machine out of the adequate
temperature range may cause defective printing (decrease of discharge).
z z z z Do not release the ink left in the cartridge into a sewer.
z z z z Do not keep Ink Cartridge with its nozzle downward.
z z z z Store under conditions which avoid freezing or direct sunlight, and temperatures of 5°C (41°F) or lower, and 35°C (95°F) or
higher. Also use the ink earlier checking the date of manufacture.
Handling and Prints of Paper
z z z z Be sure to load paper that is not curled.
z z z z Be sure to store unused paper to avoid humidity by wrapping it with packing paper.
z z z z In duplex printing, the edges of paper may be stained depending on the original.
z z z z Prints are discoloured by influence of various components in the air and light. If prints are dried sufficiently and then put in a
frame with glass or is laminated for storage, discolouration becomes small.
z z z z When storing prints in a clear file, use a file made of PET.
z z z z Prints are decolourized by moisture or sweat. Avoid storage in a location exposed to waterdrops. Also writing with an oil-based
pen may cause bleeding.
z z z z The printing density differs between prints immediately after printing and those 24 hours after printing. Note that the density
decreases as the time elapses.
z z z z Do not stack prints on other prints that are output with a laser printer or a copier that uses toner. Paper may be stuck to the
portions printed with toner or toner may be transferred to the prints.
z z z z Store paper flat avoiding high temperature, high humidity, and direct sunlight. Note that the curled paper cannot be used.
