47

HP Deskjet 3740 series printer

9.4 Manually cleaning print cartridges

If the printer is used in a dusty environment, a small amount of debris might
accumulate inside the case. This debris can include dust, hair, carpet, or clothing
fibers. When debris gets on the print cartridges and cradle, ink streaks and smudges
might appear on printed pages. Ink streaking is easily corrected by manually
cleaning the cartridges and cradle.

Gathering cleaning supplies

You will need the following items to clean the print cartridges and cradle.

• Distilled water

• Cotton swabs or other soft, lint-free material that will not stick to the cartridges

Be careful not to get ink on your hands or clothing as you clean.

Preparing to clean

1. Press the Power button to turn on the printer, and then raise the printer cover.

The cradle moves to the center of the printer.

2. Disconnect the power cord form the back of the printer.

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

1. Nozzle plate

Caution: Do not leave the print cartridges outside the printer for more
than 30 minutes.

9.7 Removing ink from skin and clothing

Follow these instructions to remove ink from skin and clothing:

Surface Remedy

Skin Wash the area with an abrasive soap.

White fabric Wash the fabric in cold water and use chlorine bleach.

Color fabric Wash the fabric in cold water and use sudsy ammonia.

Caution: Always use cold water to remove ink from fabric. Warm or hot water
can set the ink into the fabric.

9.8 Maintaining print cartridges

The following tips will help maintain HP print cartridges and ensure consistent print
quality:

50

HP Deskjet 3740 series printer

• Keep all print cartridges in their sealed packages until they are needed. Print
cartridges should be stored at room temperature (15 to 35 degrees C or 59 to
95 degrees F).

• Do not remove the plastic tape covering the ink nozzles until you are ready to
install the print cartridge in the printer. If the plastic tape has been removed
from the print cartridge, do not attempt to reattach it. Reattaching the tape
damages the print cartridge.

9.9 Maintaining the printer body

Because the printer ejects ink onto the paper in a fine mist, ink smudges will
eventually appear on the printer case and adjacent surfaces. To remove smudges,
stains, or dried ink from the exterior of the printer, use a soft cloth moistened with
water.

When cleaning your printer, keep these tips in mind:

• Do not clean the interior of the printer. Keep all fluids away from the interior.

• Do not use household cleaners or detergent. In the event that a household
cleaner or detergent is used on the printer, wipe the printer's exterior surfaces
with a soft cloth that has been moistened with water.

• Do not lubricate the support rod that the print cartridge cradle uses to slide back
and forth. Noise is normal when the cradle moves back and forth.

9.10 Printer toolbox

The printer Toolbox contains a number of useful tools to enhance the printer
performance.

Use the printer tools to perform the following tasks:

• Clean the print cartridges

• Align the print cartridges

• Print a test page

12.2 Environmental statement

Hewlett-Packard continuously improves the design processes of its deskjet printers
to minimize the negative impact on the office environment and on the communities
where printers are manufactured, shipped, and used.

EN 12281:2002).

Recycled paper: All paper documentation for this printer is printed on recycled
paper.

Ozone: Ozone-depleting chemicals such as CFCs have been eliminated from
Hewlett-Packard's manufacturing processes.

Recycling

Design for recycling has been incorporated into this printer. The number of materials
has been kept to a minimum while ensuring proper functionality and reliability.
Dissimilar materials have been designed to separate easily. Fasteners and other
connections are easy to locate, access, and remove using common tools. High­priority parts have been designed to gain access to quickly for efficient disassembly
and repair.

69

HP Deskjet 3740 series printer

Printer packaging: The packaging materials for this printer have been selected to
provide maximum protection for the least cost possible, while attempting to minimize
environmental impact and facilitate recycling. The rugged design of the HP Deskjet
printer assists in minimizing both packaging materials and damage rates.

Plastic parts: All major plastics and plastic parts are marked according to
international standards. All plastic parts used in the printer housing and chassis are
technically recyclable and all use a single polymer.

Product longevity: To ensure the longevity of your HP Deskjet printer, HP provides
the following:

• Extended warranty: Details can be found in the reference guide that came with
your printer.

• Product take-back: To return this product to HP at the end of its useful life, go
to www.hp.com/recycle. To return empty print cartridges to HP, see print

12.3 Print cartridge recovery

Customers interested in recycling their genuine HP print cartridges can participate
in HP's Planet Partner's Program for inkjet cartridges. HP offers this program in more
countries/regions than any other inkjet cartridge manufacturer in the world. This
program is provided as a free service to HP customers as an environmentally sound
solution for these products at end-of-life.

To participate, simply follow the directions provided on the HP Web site at this
address: www.hp.com/recycle. This service is not available in all countries/regions.
Customers may be asked for their name, phone number, and address.

70

HP Deskjet 3740 series printer

Because HP's unique recycling processes are very sensitive to material
contamination, we cannot take back and recycle cartridges from other
manufacturers. The end products of the recycling process are used in the
manufacture of new products, and HP must ensure the composition of the material
is consistent. To do that, we recycle only HP original cartridges. This program does
not extend to refilled cartridges.

Returned cartridges are separated for purification into raw materials for use in other
industries to manufacture new products. Examples of products made from recycled
HP print cartridge materials include automobile parts, trays used in microchip
fabrication processes, copper wire, steel plates, and the precious materials used in
electronics. Depending on the model, HP is able to recycle up to 65% of the print
cartridge by weight. The remaining parts that cannot be recycled (ink, foam, and
composite parts) are disposed of in an environmentally responsible manner.
