Turn off the main power switch before unplugging the power cord. See Turning off the main power.
The area around the vents might feel warm. This is caused by exhaust air and is not a malfunction.
If the machine is moved from a cold to a warm place, condensation may form inside it. After moving the machine, do not use it for at least an hour. The machine requires this time to adapt to its new environment.
Do not turn off the power while the machine is in operation.
Do not open the covers of the machine when it is in operation. If you do, misfeeds or malfunctions might occur.
After turning on the machine, do not open the covers of the machine until two long beeps sound. Doing so might cause a malfunction.
Do not move or tilt the machine when the power is on. Ink may leak and cause a malfunction or damage the hard disk or memory, resulting in loss of stored files.
Do not knock the machine while it is operating (for instance, do not use the machine's surfaces to knock stacks of paper into square).
If you do not use the machine for a long time, remove the paper from the paper input location and place it in its storage bag.
In addition to printing, ink is also consumed when the machine's power is turned on, head cleaning is performed, and print cartridges are installed.
The machine uses more ink when cold or hot.
The print heads will slowly return to their initial positions if the cartridge cover or paper input location cover is opened.
The print heads will stop at the position they are at when the front cover is opened. Do not leave the front cover open.
