Print cartridges are automatically cleaned at regular
intervals when the printer is on. This operation keeps
print cartridge nozzles unobstructed, to assure the correct
flow of ink. If automatic nozzle cleaning does not provide
a satisfactory print quality, perform the cleaning operation
using the clean function in the Printer Care tab. If the print
quality does not improve then, clean the electrical contacts
and manually clean the nozzles.
Cleaning the Electrical Contacts
To clean the electrical contacts:
1. Click on the Change button from the Printer Care tab.
2. Open the printer cover; then remove the print
cartridge that is causing the problem.
3. Clean the electrical contacts (golden area) of the Print
Cartridge and Print Cartridge Carriage, using a
slightly damp lint free cloth. Make sure not to touch
the print cartridge nozzles.
4. Insert the print cartridge in the printer and close the
Printer Cover.
5. Print test page to verify the quality.
Note: If print quality fails to improve, try cleaning
the Print Cartridge Nozzles.
Cleaning the Nozzles Manually
WARNING! This operation may damage the print
cartridge and should be considered ONLY as a last
resort before replacing the WHOLE print cartridge.
To clean the nozzles:
1. Click Change from the Printer Care tab.
2. Open the printer cover, unlatch and remove the print
cartridge that is causing the problem.
3. Lightly dampen a paper napkin with distilled water
and let any excess liquid drain off.
