Manually Cleaning the Print Cartridges and Print Cartridge Cradle

In order to properly clean the print cartridges and cradle, you will need distilled or
bottled water and cotton swabs or a similar lint-free absorbent material that will
not stick to the cartridges.

Manually Cleaning the Print Cartridges

1

Lower the Fold-Up tray and press the Power Button

to turn the printer on.

Then lift the top cover.

2

After the print cartridges move into an accessible position, unplug the power
cord from the back of the printer.

Keep new and used print cartridges out of the reach of children.

3

Remove the print cartridges and set them on a piece of paper with the ink
nozzle plate facing up.

Do NOT

touch the print cartridge ink nozzles or copper contacts. Touching

these parts will result in clogs, ink failure, and bad electrical connection.
Also,

do NOT

remove the copper strips; these are required electrical

contacts.

4

Dip a clean cotton swab into distilled water and squeeze any excess water from
the swab.

5

Clean the

face

and

edges

of the

print cartridge as shown.

Do NOT

wipe the nozzle plate.

6

Inspect the cartridge for fibers on
the face and edges. If fibers are
still present, repeat the cleaning
process.

7

Repeat the cleaning process for the other print cartridge.

Once you’ve removed the print cartridges, make sure that they are not
outside of the print cartridge cradle longer than 30 minutes.
