Paper Handling
Selecting Paper Types and Feed Source
One of the most important things you can do to assure the best
possible print quality from your printer is to select the correct paper.
Your printer produces letter quality output on most plain bond paper,
including cotton bond and photocopying paper; it does not require
special paper. However, the print quality varies with different paper
types. Be sure to test a small quantity of paper before you purchase a
large quantity.
You can print on any of the following paper types:

You can stack paper, envelopes, card stocks, labels, or transparencies
in the automatic paper feeder to feed automatically. The automatic
feeder can hold a maximum of 150 sheets of plain paper, and 10
envelopes or other print media. The maximum capacity may be
reduced, depending on the thickness of the paper type selected.
Note: If you experience feeding problems, try printing item at a time from
the manual feeder. See page 9.
1. Pull the extender on the automatic feeder up until it stops.

3. Load the print material in the automatic feeder. Do not load too
much print material. Do not different paper types. See the
following directions on how to load each type of print material.
¥ Load paper or transparencies with the print side facing you.
Place the print side facing you.
¥ Load envelopes with the flap side facing away from you. The stamp
area is on the bottom right corner. The end of the envelope with the
stamp area enters the feeder first.
Notes:
¥ Do not feed stamped envelopes. The stamp is shown for placement only.
¥ Never use envelopes with clasps, snaps, windows, coated linings, or
self-stick adhesives.
¥ These envelopes may severely damage the printer.
¥ Load letterhead paper with the design facing you. The top edge of
the sheet with the logo should enter the printer first.

Notes:
¥ The face-up stacker may not hold the printed materials properly.
¥ The printed pages will not stack in the standard face-down stacker unless
you close the face-up stacker. The face-down stacker can hold up to 100
printed pages. When you finish using the face-up stacker, you must close
it.
Paper Guidelines
When selecting or loading paper, envelopes, or other special media,
keep these guidelines in mind:
¥ Attempting to print on damp, curled, wrinkled, or torn paper can
cause paper jams and poor print quality.
¥ Use cut-sheet paper only. You cannot use multipart paper.
¥ Use only high quality, copier grade paper. Avoid paper with
embossed lettering, perforations, or texture that is too smooth or too
rough.
¥ Colored paper should be of the same high quality as white
photocopy paper. The pigments must withstand the printerÕs fusing
temperature of 392 oF (200 oC) for 0.1 second without deterioration.
Do not use paper with a colored coating that was added after the
paper was produced.
¥ Pre-printed forms must be printed with non-flammable, heat-
resistant inks that do not melt, vaporize, or release hazardous
emissions when subjected to the printerÕs approximately 392 oF (200
o
C) fusing temperature for 0.1 seconds.
¥ Store paper in its ream wrapper until you are ready to use it. Place
cartons on pallets or shelves, not on the floor. Do not place heavy
objects on top of the paper, whether it is packaged or unpackaged.
Keep it away from moisture, or other conditions that can cause it to
wrinkle or curl.
¥ During storage, moisture-proof wrap (any plastic container or bag)
should be used to prevent dust and moisture from contaminating
your paper.
¥ Always use paper and other media that conform with those listed
under ÔSpecificationsÕ on page 33.
¥ When you choose envelopes, use only well-constructed envelopes
with sharp, and well creased folds.
- DO NOT use envelopes with clasps and snaps.
- DO NOT use envelopes with windows, coated linings, self-stick
adhesives, or other synthetic materials.
- DO NOT use damaged or poorly made envelopes.
- DO NOT use envelopes with affixed stamps.

Operating Your Printer
15
Quality Tab
On the Quality tab, you can adjust the print quality of your
document by setting resolution. Higher resolution looks better but
takes longer to print and requires more memory. You can also adjust
the Lighten/Darken and contrast for all graphics in your documents.
Output TypeÕs Quality : Each of the selections on the output quality
correspond to a pre-determined halftone is used by the driver. If text is
selected then a halftone that is optimal for text printing is used by the driver.
The normal option uses the new halftone that we have optimized for your
printer engine. Photographic selects a halftone that is optimized for printing
images at a higher quality.
Lighten/Darken/Contrast : When youÕre printing documents that contain
areas of gray, you may find the results you get from the ML-5050G Series
driver can be significantly lighter than from other printer drivers (especially
laser printer drivers). The ML-5050G Series driver corrects output to render
grays more nearly like those you see on your screen; most other drivers do
not. You can use any of the above settings to alter the output to you liking.
For Help on each item, click ? at the top of the dialog box, and then
click the desired item.
Advanced Tab
The options on the Advanced Tab are designed mostly for
troubleshooting application or file specific problems.
Color Documents : Some applications do not recognize the inherent colorhandling capabilities of your ML-5050G Series printer. It is for these
applications that the option Color Document exists. One application that
requires this setting to be on is Microsoft PowerPoint. If you find that you
are not getting correct grays from an application, you should try toggling
this option.
Graphics : MicrosoftÕs specifications for communicating to Windows
printer drivers are sufficiently ÒlooseÓ that different software developers have
invented (or borrowed) special driver ÒescapesÓ (unusual instruction codes).
The set of escapes invented by Micrografx can provide substantial
performance gains. Applications that either require or work better with
Graphics turned on include Lotus Freelance for Windows and most
Micrografx software. In general, if performance when rendering complex
graphics is either very slow, or yields unsatisfactory output, you should try
toggling this setting.
16
Operating Your Printer
Dither Line : Most output devices rely on dithering to achieve shades of
gray. With the Dither Lines option on (the default), your ML-5050G Series
printer gives you accurate grays even if it has to dither them. You get exactly
what you ask for. However, fine dithered lines appear dashed instead of solid.
With the Dither Lines option off, your ML-5050G Series printer maps text
and lines to the nearest gray. For black & white output, grays that are darker
than about 50% map to black; lighter grays map to white. For color, colors
map to the nearest gray.
Dither Text : Most output devices rely on dithering to achieve shades of
gray. With the Dither Text option on (the default), your ML-5050G Series
printer gives you accurate grays even if it has to dither them. You get exactly
what you ask for. However, small dithered text is difficult to read. With the
Dither Text option off, your ML-5050G Series printer maps text and lines
to the nearest gray. For black & white output, grays that are darker than
about 50% map to black; lighter grays map to white. For color, colors map to
the nearest gray.
Accept Larger Bitmap Pattern : When an application sends a bitmap fill
pattern (also called a Òpattern brushÓ) to the printer, the expected, standard
size is 8 pixels square. Some applications are able to send larger patterns. If
Accept Larger Bitmap Pattern is on, and you encounter output where your
bitmap fills have repeating pattern anomalies in them, try turning it off.
Bitmap fill patterns can be used for any repeated design, or even to simulate
grayscale dithering. Some applications send box tints as bitmap patterns.
One problem that arises with this is that some programs donÕt make
allowances for the difference between screen resolution and printer
resolution. (Another problem is that some do!) The typical result is that
patterns printed to a laser printer get very small, and tints get too dark.
Scale : Your ML-5050G Series has a process that automatically enlarges the
bitmap fill patterns so that the output more closely matches the screen. For
example, with the default, ÒautomaticÓ setting of Scale: 0, patterns that come
from a VGA system (96x96 logical pixels per inch) are enlarged
three times to (almost) match the 300x300 dpi of a laser printer. If you set
Scale to 1, your printer can handle the brush patterns exactly as they come
from the application-no scaling. You can also
force your printer to scale by 2, 3, 4, or more times by entering larger
numbers.
Operating Your Printer
17
Adobe and True Type Font Engine Checkboxes : The primary use of this
feature is for troubleshooting by a process of elimination with a limited
number of applications. If your printing works OK, you should ignore these
settings. In some circumstances, certain applications can cause problems
with your ML-5050G Series printer when the document uses typefaces
installed in Adobe Type Manager software (ATM) or TrueType. If you have
both font engines, you could also run into substitution problems. Turning
the TrueType checkbox on speeds up handling of True Type fonts by sending
them as text. With this option off, fonts are handled as graphics. This can be
useful if you are printing over a network to a server that does not have the
same typeface you are using on your workstation PC. Since the data is sent
as graphics, you do not run into font substitution problems. If you are
printing with characters found in languages like Japanese or Chinese (also
called double-byte characters), the True Type checkbox should be off.
