STEP 3: Loading Paper
The HP DeskJet 420 series printer prints on plain
paper and other paper types. Most plain paper used
for photocopying yields good results. See page 17,
“Recommended Printable Weight,” for information on
other paper types you can use. See also page 6 for
information on loading other size paper, envelopes,
labels, and thick paper.
1. Remove the packing tape to release the
paper tray.
2. Open the paper tray.
3. Extend the paper tray to the appropriate mark
(US Letter or A4) for the paper size you are
using.
4. Switch the paper size selector to match the
paper you are using
(LTR
or
A4).
5. Insert a stack of paper squarely into the paper
tray, print side down, until it can go no farther.
Note: If you are loading letterheads or HP transparencies,
insert them print side down, with the top of the page
going into the printer first.
6. Move the paper width guide so that it presses
lightly against the paper stack.
