Frequently Asked Questions
What is the difference between
LTR and A4 paper?
LTR paper is commonly used in North America.
The size is 8.5 inches x 11 inches (216 mm x 279 mm).
A4
paper is commonly used in Europe, Australia,
New Zealand, Asia, and South America. The size is
210 mm x 297 mm.
How should paper be loaded into
the printer?
First, switch the paper size lever on the left bottom
corner to the correct paper setting, either LTR or A4.
Then insert the paper into the paper tray until it can
go no further. Finally, move the paper width guide,
located on the tray, so that it presses lightly against
the paper stack.
Is the sound the printer makes
when it starts working normal?
Yes, when the printer functions properly, a sound
occurs when you turn the printer on and also when it
picks up paper. The sound when you turn the printer
on is the print cartridge finding its starting position.
The sound when the printer picks up paper is due to
the activation of the printer mechanism.
What print cartridges can I use
with the printer?
Use the HP black cartridge (HP part no. 51626A) for
great looking black output. Purchase the optional HP
color cartridge (HP part no. 51625A) for color output.
How do I print in color using
Microsoft Windows software?
Use the optional HP color cartridge (HP part no.
51625A) for color printing and use the HP black print
cartridge (HP part no. 51626A) for black printing. If you
print in black, remember to check the Print in
Grayscale
setting in the printer setup menu.
How can I get the best print
quality?
To ensure the highest print quality from the HP DeskJet
400 series printer, use original HP print cartridges
together with HP’s Premium InkJet Paper or Premium
Glossy Paper.
The HP printer software gives you optimal results
when you select the Best printing setting in the printer
setup menu.
How do I print envelopes, labels, or
thick paper (heavier than 24 lb)?
You must feed envelopes, labels, and thick paper one
sheet at a time from the back of the printer. Be sure that
you have selected Manual Feed and the appropriate
Paper Size
in the printer setup menu. Then open the
printer door and switch the envelope lever to Envelope.
Close the printer door and print one page.
What do I do if I get a paper
path error?
To clear the paper path error:
1. Turn off the printer.
2. Remove the paper from the paper tray.
3. Remove the printer door by grasping it by its
sides, then pulling the door up.
4. Carefully pull the paper out of the printer.
To avoid paper path errors, be sure to set the paper size
lever to the correct setting and to move the paper width
guide so that it presses lightly against the paper stack.
Also, be sure to feed paper that is heavier or lighter than
16 to 24 lb from the back of the printer manually.
