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 77
If the nozzle check pattern has missing dots, perform a print head cleaning.
See “Head cleaning” on page 79
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 67
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 88
The print head moves, but nothing
prints.
Is the message Motor Self Adjustment displayed on the control panel's screen?
