• Print cartridges should be used up before their expiry date, ideally within six months of being
removed from their packaging.
• Cartridges that are no longer usable for printing reserve a small quantity of ink for maintenance
usage.
• Print cartridges and supplies comply with the manufacturer's safety specifications. To ensure safety
and reliability, use genuine print cartridges and supplies.
• Single-sided copies are printed at higher density than duplex-printed copies.
• Printing hundreds of copies in a single day might cause the print head to clog the following day. If
this happens, perform the head cleaning procedure.
• This machine performs regular automatic maintenance, after and during printing, to ensure
consistent print quality. Maintenance is also performed when printing begins after a period of
disuse.
• Color ink may be used even if you print all-black text or if you specify black and white printing. It
may also be used for print head cleaning and refreshing, which are done to maintain machine
performance.
• If the machine will not be used for a long time, turn its power off, disconnect the USB cable, and
unplug the power cord from the wall outlet. Because the machine consumes a lot of ink for
maintenance and print head cleaning when turned on after a long period of inactivity, we
recommend you use the machine at least once a month.
• Do not move the machine while it is powered. Even when it is off, make sure the machine is on a
level surface and safe from shock and vibration.
• Do not turn the machine off while it is busy. Make sure the machine is idle before turning it off.
• Condensation can form inside the machine if it is moved from a cold place to a warm place. Allow
any condensation to fully evaporate by not turning the machine on for at least an hour after moving
it.
