The printer sounds like it is printing, but nothing prints
Cause What to do
The ink cartridges may have
a problem.
If the print head moves, but nothing prints, confirm the printer operation.
Print a nozzle check pattern. You can check the printer’s operation and
status without connecting the printer to the computer.
See “Nozzle check” on page 76
If the nozzle check pattern has missing dots, perform a print head cleaning.
See “Head cleaning” on page 78
If you replace the ink cartridges while the printer is turned off, the remaining
amount of ink cannot be detected correctly so that the Ink Check light does
not come on even when the ink cartridge needs to be replaced; otherwise
you cannot print correctly. Be sure to follow the instructions in this manual to
replace the ink cartridge.
See “Replacing Ink Cartridges” on page 66
Has the printer not been used for a long time?
If the printer has not been used for a long time, the nozzles are dried and
may be clogged. See the following section.
“If you have not used your printer for more than six months” on page 87
The print head moves, but
nothing prints.
Is the message Motor Self Adjustment displayed on the control panel's
screen?
The printer adjusts the internal motor. Wait for a while without turning off the
printer.
