Wiping the print nozzles and contacts
If the print quality does not improve after purging the nozzles, the contacts may be dirty or there may be dried ink on the nozzles.
Wiping the print nozzles
Remove the print cartridge from the machine, see "To replace an empty ink cartridge" on page 51.
Dampen a clean cloth with water.
To dissolve any dried ink, hold a damp cloth against the nozzles for about 3 seconds and wipe gently. To avoid mixing colours, wipe from one side to the other, in one direction as shown.
Wiping the contacts
Using a clean damp area of the cloth, gently wipe the entire gold covered area, on the back of the cartridge, from one side to the other, as shown.
Gently wipe dry.
Ensure cartridge is dry before replacing in the machine.
Allow the nozzles to dry.
