HP LaserJet M4345 User Manual

							Label construction
When selecting labels, consider the quality of each component:
●Adhesives:
 The adhesive material should be stable at 200C (392F), the printers fusing
temperature.
● Arrangement:
 Only use labels with no exposed backing between them. Labels can peel off
sheets with spaces between the labels, causing serious jams.
● Curl:
 Prior to printing, labels must lie flat with  no more than 13mm (0.5inch) of curl in any
direction.
● Condition:
 Do not use labels with wrinkles, bubbles, or other indications of separa\
tion.
NOTEChoose labels in the printer driver (see Supported printer drivers).
Transparencies
Transparencies used in the printer must be able  to withstand 200C (392F), the printers fusing
temperature.
CAUTION To avoid damaging the MFP, use only transparencies recommended for use in
HPLaserJet printers, such as HP-brand transparencies.
NOTE Choose transparencies in the printer driver (see Supported printer drivers).
Card stock and heavy media
You can print many types of card stock from the paper input tray, including index cards and
postcards. Some card stock performs better than others because its construction is better suited for
feeding through a laser printer.
For optimum printer performance, do not use paper heavier than 157g/m
2 (42lb). Paper that is too
heavy might cause misfeeds, stacking problems, paper jams,  poor toner fusing, poor print quality, or
excessive mechanical wear.
NOTE You might be able to print on heavier paper if you do not fill the input tray to capacity
and if you use paper with a smoothness rating of 100-180Sheffield.
Card stock construction
● Smoothness : 135-157g/m2 (36-42lb) card stock should have a smoothness rating of
100-180Sheffield. 60-135g/m2 (16-36lb) card stock should have a smoothness rating of
100-250Sheffield.
● Construction
: Card stock should lie flat with less than 5mm (0.2in.) of curl.
● Condition
: Make sure that the card stock is not wrinkled, nicked, or otherwise damaged.
● Sizes
: Only use card stock within the following size ranges:
● Minimum
: 76x127mm (3x5in.)
● Maximum
: 216x356mm (8.5x14.0in.)

							Card stock guidelines
Set margins at least 2mm (0.08in.) away from the edges.
Letterhead and preprinted forms
Many manufacturers now offer premium paper advertised as laser-compatible or laser-guaranteed.
Some of the rougher surface finishes, such as cockle, laid, or linen, might require the special fuser
modes that are available on some printer models in order to achieve adequate toner adhesion.
NOTESome page-to-page variation is normal when printing with laser printers. This
variation cannot be observed when printing on  plain paper. However, this variation is obvious
when printing on preprinted forms because the lines and boxes are already placed on the page.
To avoid problems when using preprinted forms, embossed paper, and letterhead, observe the
following guidelines:
● Avoid using low-temperature inks (the kind used with some types of thermography).
● Use preprinted forms and letterhead paper that have been printed by offset lithography or
engraving.
● Use forms that have been created with heat-resistant 
inks that will not melt, vaporize, or release
undesirable emissions when heated to 200C (392F) for 0.1second. Typically, oxidation-set or oil-
based inks meet this requirement.
● When the form is preprinted, be careful not to 
change the moisture content of the paper, and do
not use materials that change the papers electrical  or handling properties. Seal the forms in
moisture-proof wrap to prevent moisture changes during storage.
● Avoid processing preprinted forms that have a finish or coating.
● Avoid using heavily embossed or raised-letterhead papers.
● Avoid papers that have heavily textured surfaces.
● Avoid using offset powders or other materials that prevent printed forms from sticking together.
Select the correct fuser mode
The device automatically adjusts the fuser mode based on the media type to which the tray is set.
For example, heavy paper, such as card stock, might need a higher fuser-mode setting in order to
make the toner adhere better to the page,
 but transparencies need a lower fuser-mode setting to
avoid damage to the device. The default setting generally provides the best performance for most
print-media types.
The fuser mode can be changed only if the media  type has been set for the tray that you are using.
See 
Control print jobs . After the media type has been set for the tray, then the fuser mode for that
type can be changed on the  Administration menu in the Print Quality submenu at the device control
panel. See 
Print Quality menu .
NOTE Using the  High 1 or High 2  fuser mode setting improves the ability of the toner to
adhere to paper, but it might cause other problems, such as excessive curl. The device might
print at a slower speed when the fuser mode is set to  High 1 or High 2 . The table below
describes the ideal fuser mode  setting for supported media types.

							Printing and paper-storage environment
Ideally, the printing and paper-storage environment should be at or near room temperature, and not
too dry or too humid. Remember paper is  hygroscopic; it absorbs and loses moisture rapidly.
Heat works with humidity to damage paper. Heat causes the moisture in paper to evaporate, while
cold causes it to condense on the sheets. Heating  systems and air conditioners remove most of the
humidity from a room. As paper is opened and used, it loses moisture, causing streaks and
smudging. Humid weather or water coolers can cause the humidity to increase in a room. As paper is
opened and used it absorbs any excess moisture, causing light print and dropouts. Also, \
as paper
loses and gains moisture it can distort. This can cause jams.
As a result, paper storage and handling are  as important as the paper-making process itself. Paper
storage environmental conditions directly affect the feed operation.
Care should be taken not to purchase more paper than  can be easily used in a short time (about 3
months). Paper stored for long periods might experience heat and moisture extremes, which can
cause damage. Planning is important to prevent damage to a large supply of paper.
Unopened paper in sealed reams can remain  stable for several months before use. Opened
packages of paper have more potential for environmental damage, especially if they are not wrapped
with a moisture-proof barrier.
The paper-storage environment should be properly maintained to ensure optimum product
performance. The required condition is 20° to  24°C (68° to 75°F), with a relative humidity of
45% to 55%. The following guidelines should be  helpful when evaluating the papers storage
environment:
● Paper should be stored at or near room temperature.
● The air should not be too dry or too humid (due to the hygroscopic properties of paper).
● The best way to store an opened ream of 
paper is to rewrap it tightly in its moisture-proof
wrapping. If the product environment is subject to  extremes, unwrap only the amount of paper to
be used during the days operation to prevent unwanted moisture changes.
● Proper storage of envelopes helps contribute to print
 quality. Envelopes should be stored flat. If
air is trapped in an envelope, creating an  air bubble, then the envelope might wrinkle during
printing.

							Load media
This section contains information about loading standard- and custom-size media into the input trays.
CAUTIONTo avoid a jam, never add or remove paper from a tray while printing or copying
from that tray. To avoid damaging the MFP,  print labels and envelopes from tray1 only. Print
on only one side of labels, envelopes, and transparencies.
Load the flatbed scanner
Place the document face-down on the scanner glass.
Load the ADF
Load the document face-up in the ADF.
Load tray1
Tray1 holds up to 100 sheets of paper  or 10 envelopes. For more information about supported
media, see 
Select print media .
Use the following procedure if tray1 is loaded continually  with the same type of media, and the media
is not usually removed from tray1 between print  jobs. The following procedure can also increase the
MFP performance when printing from tray1.
CAUTION To avoid a jam, never add or remove media from a tray while printing from that
tray.
1. Touch  Copy.
2. Touch  Paper Selection .
3. Touch  Tray 1 Any Size .
4. Touch the correct media size.
NOTE If you select  Custom as the media size, also select the unit of measure and the
X and Y dimensions.
5. Touch  OK.
6. Touch  OK again.
7. Open tray1.
