Do the stripes look like they are caused by missing ink, or smeared ink? The
fixes are different.
If one or more of the nozzles are clogged, (missing ink) it can sometimes be
fixed by using the 'cleaning' function in the HP windows software. If that
won't work for you, get a new ink cartridge. Usually the first sign of
missing ink means that the cartridge will need to be replaced soon.
If you see horizontally smeared or dragged ink, take the ink cartridges out
and clean under the carriage that holds them. Also check the carriage parking
area (probably to the right) for ink-soaked debris such as cat hair, lint,
paper fibers, etc. You need to be careful when cleaning these parts. There is
help available in the HP windows software.
If you don't have access to the cleaning instructions, here is what you can
do, but be careful.
Open the cover, wait for the ink carriage to move to the center, then shut
off and (important for safety) disconnect all wires and cables from the
printer.
Take out the ink cartridges.
Get some cotton swabs (often sold under the "Q-tip" brand in the US). Dip one
in warm water, then roll it between your fingers to make sure it can't drip
or lose fibers inside the printer. Use it to wipe any collected ink or debris
from around and underneath the ink carriage where the print heads were.
Repeat until the area is clean. Be careful not to touch any of the electrical
contacts. On the right (probably), there is a parking area with four small
rubber parts that may have debris on them. Very gently clean them with the
damp swabs. Avoid touching the rubber parts with your fingers.
If you accidentally get a drop of water in the printer, don't allow it to
remain.

Here's an odd printer service problem that occurred to me last spring - It's
not related to your trouble, but I though I'd tell it here.

My OfficeJet 600 had some kind of problem that caused the paper to jam every
time I tried to use the printer. I barely remembered hearing 'snapping'
noises coming from the printer a couple of days previously, so I was a little
worried.
After pulling out the easily removable parts, I could see the the cause. The
printer was suffering from a 'hardware bug'. Resting against a roller was a
large (by now dead) hard-bodied beetle.
After a cleanup, the printer works fine.
