Using the operator panel

This section contains information about understanding the operator panel, changing printer settings,
and understanding operator panel menus.

You can change most printer settings from your software application or printer driver. Settings you
change from the application or printer driver apply only to the job you are preparing to send to the
printer.

Changes made to printer settings from a software application override changes made from the printer
operator panel.

If you cannot change a setting from your application, use the printer operator panel or the remote
operator panel available from MarkVision™. Changing a printer setting from the printer operator panel
or from MarkVision makes that setting the user default.

Understanding the operator panel

The printer operator panel has a 2-line by 16-character liquid crystal display (LCD), five buttons, and
one indicator light.

Using the Print and Hold function

When sending a job to the printer, y ou can specify in the driver that you want the printer to hold the job
in memory. When you are ready to print the job, you must go to the printer and use the operator panel
menus to identify which held job you want to print.

Note: Print and Hold functions require a minimum of 16MB available printer memory . W e

recommend a minimum of 32MB available printer memory and a hard disk.

Printing and deleting held jobs

Once held jobs are stored in printer memory, you can use the printer operator panel to specify what
you want to do with one or more of the jobs. You can select either Confidential Job or Held Jobs
(Repeat Print, Reserve Print, and Verify Print jobs) from the Job Menu. If you select Confidential Job,
you must enter the personal identification number (PIN) you specified in the driver when you sent the
job. See Confidential jobs for more information.

From either the Confidential Job or the Held Jobs menu items, you have five choices:

• Print All Jobs

• Print A Job

• Delete All Jobs

• Delete A Job

• Print Copies

15

Accessing held jobs from the operator panel

1 To access held jobs from the operator panel:

– If the printer is Busy, press Menu and the Job Menu appears.
– If the printer is Ready, continue to step 2.

2 Press Menu until you see Held Jobs or Confidential Job on the operator panel display,

depending on the type of job you want to access.

3 Press Select.

User Name appears on the first line of the operator panel. The second line displays the names
of users currently associated with Print and Hold jobs.

4 Press Menu until you see your user name.

Note: If you are looking for a Confidential Job, you are prompted to enter your PIN. See

Confidential jobs for more information.

5 Press Select.
6 Press Menu until the action you want to take is on the second line of the operator panel (Print

A Job, Delete A Job, and so on).

7 Press Select.

– If you are looking for a particular job, press Menu to scroll through the list of available jobs,

and press Select when the correct job is displayed. An asterisk (*) appears next to the job
name indicating you have chosen to print or delete that job.

– If you are prompted to enter the number of copies you want to print, use the Menu button

to increase or decrease the number on the display, and then press Select.

8 Press Go to print or delete specific jobs you have marked.

The printer briefly shows messages indicating what Print and Hold functions it is performing.

Recognizing when format errors occur

If the symbol appears on the display, it indicates that the printer had trouble formatting one or more
of the held jobs. These formatting problems are most commonly the result of insufficient printer
memory or invalid data that might cause the printer to flush the job.

When a symbol appears next to a held job, you can:

• Print the job. Be aware, however, that only part of the job may print.

• Delete the job. You may want to free up additional printer memory by scrolling through the list

of held jobs and deleting others you have sent to the printer.

If formatting errors are a recurring problem with held jobs, your printer may require more memory.

16

Repeat Print

If you send a Repeat Print job, the printer prints all requested copies of the job and stores the job in
memory so you can print additional copies later. You can print additional copies as long as the job
remains stored in memory.

Note: Repeat Print jobs are automatically deleted from printer memory when the printer

requires extra memory to process additional held jobs.

Reserve Print

If you send a Reserve Print job, the printer does not print the job immediately, but stores the job in
memory so you can print the job later. The job is held in memory until you delete it from the Held Jobs
menu. Reserve Print jobs may be deleted if the printer requires extra memory to process additional
held jobs.

See Printing and deleting held jobs for information.

Verify Print

If you send a Verify Print job, the printer prints one copy and holds the remaining copies you requested
from the driver in printer memory. Use Verify Print to examine the first copy to see if it is satisfactory
before printing the remaining copies.

See Printing and deleting held jobs if you need help printing the additional copies stored in memory.

Note: Once all copies are printed, the Verify Print job is deleted from printer memory.

Confidential jobs

When you send a job to the printer, you can enter a personal identification number (PIN) from the
driver. The PIN must be four digits using the numbers 1–6. The job is then held in printer me mo ry unti l
you enter the same four-digit PIN from the printer operator panel and choose to print or delete the job.
This ensures that the job does not print until you are there to retrieve it, and no one else using the
printer can print the job.

When you select Confidential Job from the Job Menu and then select your user name, the following
prompt is displayed:

Enter PIN:
=____

17

Use the buttons on the operator panel to enter the four-digit PIN associated with your confidential job.
The numbers next to the button names identify which button to press for each digit (1–6). As you enter
the PIN, asterisks are displayed on the operator panel to ensure confidentiality.

Choosing print material

The print quality and feed reliability of your printer and options can vary with the type and size of print
material you use. This section provides guidelines for each type of print material. For information on
card stock and labels, refer to the Card Stock & Label Guide located on Lexmark’s Web site at

www.lexmark.com.

Always print samples on the print material you are considering before buying large quantities.

Paper characteristics

The following paper characteristics affect print quality and reliability. We recommend that you keep
these guidelines in mind when evaluating new paper stock.

For detailed information, refer to the Card Stock & Label Guide located on the Lexmark Web site at

www.lexmark.com.

Weight

The printer can automatically feed paper weights from 60 to 176 g/m2 (16 to 47 lb bond) grain long.
Paper lighter than 60 g/m
best performance, use 75 g/m
mm (7.2 x 10.1 in.), we recommend that the weight be greater than or equal to 90 g/m

2

(16 lb) might not be stiff enough to feed properly, causing paper jams. For

2

(20 lb bond) grain long paper. To use paper narrower than 182 x 257

21

2

(24 lb bond).

Curl

Curl is the tendency of paper to curve at its edges. Excessive curl can cause paper feeding problems.
Curl usually occurs after the paper passes through the printer, where it is exposed to high
temperatures. Storing paper unwrapped in humid conditions, even in the paper tray, can contribute to
paper curling.

Smoothness

The degree of smoothness of paper directly affects print quality. If the paper is too rough, the toner
does not fuse to the paper properly, resulting in poor print quality. If the paper is too smooth, it can
cause paper feeding problems. Smoothness needs to be between 100 and 300 Sheffield points;
however, smoothness between 100 and 175 Sheffield points produces the best print quality.

Moisture content

The amount of moisture in the paper affects both print quality and the ability of the printer to feed the
paper properly. Leave the paper in its original wrapper until you are ready to use it. This limits the
exposure of the paper to moisture changes that can degrade its performance.

Grain direction

Grain refers to the alignment of the paper fibers in a sheet of paper. Grain is either grain long, running
the length of the paper, or grain short, running the width of the paper.

2

For 60 to 176 g/m
than 176 g/m
36 lb bond) paper, grain long fibers are recommended. For the multipurpose feeder, papers heavier
than 135 g/m

(16 to 47 lb bond) paper, grain long fibers are recommended. For papers heavier

2

(47 lb bond), grain short is preferred. For the multipurpose feeder, 60 to 135 g/m2 (16 to

2

(36 lb bond), grain short is preferred.

Fiber content

Most high-quality xerographic paper is made from 100% chemically pulped wood. This content
provides the paper with a high degree of stability resulting in fewer paper feeding problems and better
print quality. P aper containing fibers such as cotton possess characteristics that can result in degraded
paper handling.

Recommended paper

To ensure the best print quality and feed reliability, use 75 g/m2 (20 lb) xerographic paper. Business
papers designed for general business use may also provide acceptable print quality.

Always print several samples before buying large quantities of any type of paper. When choosing any
papers, consider the weight, fiber content, and color of the paper.

The laser printing process heats paper to high temperatures of 225°C (437°F) for Magnetic Ink
Character Recognition (MICR) applications, and 205°C (401°F) for non-MICR applications. Use only
papers that are able to withstand these temperatures with out disc olo ring, bleeding, or releasing
hazardous emissions. Check with the manufacturer or vendor to determine whether the paper you’ve
chosen is acceptable for laser printers.

22

Unacceptable paper

The following papers are not recommended for use with the printer:

• Chemically treated papers used to make copies without carbon paper, also known as

carbonless papers, carbonless copy paper (CCP), or no carbon required (NCR) paper

• Coated papers (erasable bond)

• Multiple-part forms or documents

• Preprinted papers that require a registration (the precise print location on the page) greater

than ±0.09 in., such as optical character recognition (OCR) forms
In some cases, you can adjust registration with your software application to successfully print

on these forms.

• Preprinted papers with chemicals that may contaminate the printer

• Preprinted papers that can be affected by the temperature in the printer fuser

• Rough-edged or curled papers

• Synthetic papers

• Thermal papers

• Less than 60 g/m

2

(16 lb) recycled paper

• Recycled papers containing more than 25% post-consumer waste that do not meet DIN 19

309

Choosing preprinted forms and letterhead

Use the following guidelines when selecting preprinted forms and letterhead paper for the printer:

• Use grain long papers for best results.

• Use only forms and letterhead printed using an offset lithographic or engraved printing

process.

• Choose papers that absorb ink, but do not bleed.

• Avoid papers with rough or heavily textured surfaces.

Use papers printed with heat-resistant inks designed for use in xerographic copiers. The ink must
withstand temperatures of 225°C (437°F) without melting or releasing hazardous emissions. Use inks
that are not affected by the resin in the toner. Inks that are oxidation-set or oil-based should meet these
requirements. Latex inks might not meet these requirements. If you are in doubt, contact your paper
supplier.

23

Choosing prepunched paper

Prepunched paper brands can differ in the number and placement of holes and in manufacturing
techniques.

Use the following guidelines when selecting and using prepunched paper:

• Test paper from several manufacturers before ordering and using large quantities of

pre-punched paper.

• Paper should be punched at the paper manufacturer and not drilled into paper already

packaged in a ream. Drilled paper can cause paper jams when multiple sheets feed through
the printer.

• Prepunched paper can include more paper dust than standard paper. Your printer may require

more frequent cleaning and your feed reliability may not be as good as that of standard paper.

• Weight guidelines for prepunched paper are the same as for nonpunched paper.

Choosing paper

Proper paper loading helps prevent paper jams and ensure trouble-free printing.
To help avoid paper jams or poor print quality:

• Always use new, undamaged paper.

• Before loading paper, know the recommended print side of the paper you’re using. This

information is usually indicated on the paper package.

• Do not use paper that you have cut or trimmed yourself.

• Do not mix paper sizes, weights, or types in the same paper source; mixing results in paper

jams.

• Do not use coated papers.

• Do not forget to change the Paper Size setting when you use a source that does not support

auto size sensing.

• Do not remove paper trays while a job is printing or Busy is displayed on the operator panel.

• Make sure the Paper Type, Paper Texture, and Paper Weight settings are correct. (See Paper

Menu for detailed information about these settings.)

• Make sure the paper is properly loaded in the paper source.

• Flex paper back and forth. Do not fold or crease the paper. Straighten the edges on a level

surface.

24

Choosing envelopes

When printing on envelopes:

• To achieve the best possible print quality, use only high-quality envelopes that are designed for

use in laser printers.

• Use only new, undamaged envelopes.

• Load only one size of envelope at a time in the envelope feeder.

• Make sure the glue is not exposed.

• A combination of high humidity (over 60%) and the high printing temperatures may seal the

envelopes.

• Be sure to select Env Feeder or MP Feeder as the paper source in the Paper Menu and set

the correct envelope size.

The laser printing process heats envelopes to a temperature of 205°C (401°F). Use only envelopes
that are able to withstand these temperatures without sealing, excessive curling, wrinkling, or releasing
hazardous emissions. If you have any doubts about the envelopes you are considering using, check
with the envelope supplier.

(20 lb bond) paper. You can use up to 105 g/

To minimize jams, do not use envelopes that:

• Have excessive curl or twist

• Are stuck together or damaged in any way

• Contain windows, holes, perforations, cutouts, or embossing

• Use metal clasps, string ties, or metal folding bars

• Have an interlocking design

• Have postage stamps attached

• Have any exposed adhesive when the flap is in the sealed or closed position

• Have nicked edges or bent corners

• Have rough, cockle, or laid finishes

Choosing labels

The printer can print on many labels designed for use with laser printers. These labels are supplied in
letter size and A4 size sheets.

When printing on labels:

• Be sure to select Labels in the Paper Type menu item in the Paper Menu. (See Paper Ty pe for

detailed information about these settings.)

• Do not load labels together with paper or transparencies in the same paper tray; mixing print

materials can cause feeding problems.

25

• Do not load partial sheets with areas exposed by missing labels; this can cause labels to peel

off during printing, jam, and contaminate your printer and your print cartridge with adhesive. It
can also void your printer and cartridge warranties.

• Avoid using labels that may release hazardous emissions when heated.

Note: Labels are one of the most difficult print materials for laser printers. The T620 and

T622 printers require a special fuser cleaner for label applications in order to
optimize feed reliability. See Ordering supplies for information on obtaining a
label fuser cleaner.

After continuously printing approximately 10,000 page sides of labels (or each time you replace the
print cartridge), complete the following steps to maintain printer feeding reliability:

1 Print five sheets of paper.
2 Wait approximately five seconds.
3 Print five more sheets of paper.

For detailed information on label printing, characteristics, and design, refer to the Card Stock & Label
Guide, available on Lexmark Web site at www.lexmark.com.

Choosing card stock

Card stock is single-ply and has a large array of properties. The orientation of paper fibers, moisture
content, thickness, and texture can all affect printing on card stock. See Paper specifications for
information on the preferred weight for the grain direction of print materials.

When printing on card stock:

• Be sure to select Card Stock in the Paper Type menu item in the Paper Menu. (See Paper

Type for detailed information about these settings.)

• Be aware that preprinting, perforation, and creasing can significantly affect the print quality and

cause paper handling or jamming problems.

• Avoid using card stock that may release hazardous emissions when heated.

After printing approximately 10,000 page sides of card stock (or each time you replace the print
cartridge), complete the following steps to maintain printer feeding reliability:

1 Print five sheets of paper.
2 Wait approximately five seconds.
3 Print five more sheets of paper.

For more information, refer to the Card Stock & Label Guide, available on the Lexmark Web site at

www.lexmark.com.

26

Choosing transparencies

The printer can print directly on transparencies designed for use in laser printers. Print quality and
durability depend on the transparency used. Always print samples on the transparencies you are
considering before buying large quantities.

The Paper Type setting should be set to Transparency to help prevent jams. (See Paper Type for
detailed information about this setting.) Check with the manufacturer or vendor to determine whether
your transparencies are compatible with laser printers that heat transparencies to 212°C (414°F). Use
only transparencies that are able to withstand these temperatures without melting, discoloring,
offsetting, or releasing hazardous emissions. For detailed information, refer to the Card Stock & Label
Guide, which is available on the Lexmark Web site at www.lexmark.com.

Transparencies can be fed automatically from the multipurpose feeder and all standard and optional
trays, except the 2000-sheet drawer, for all printer models. See Print material specifica tions for
information about transparency compatibility with output options.

Be careful when you handle transparencies. Fingerprints on the surface of the transparency cause
poor print quality.

Storing paper

Properly storing the paper you buy helps ensure trouble-free printing. Use the following guidelines:

• For best results, store paper in an environment where the temperature is approximately 21

• Store cartons of paper on a pallet or shelf, rather than directly on the floor.

• If you store individual packages of paper out of the original carton, make sure they rest on a

Loading the multipurpose f eeder

The multipurpose feeder can hold several sizes and types of paper, such as transparencies, postcards,
note cards, and envelopes. It is useful for single page printing on letterhead, colored paper, or other
special paper.

Keep in mind the following capacities, paper dimensions, and operating tips when loading the
multipurpose feeder.

Capacity

The maximum stack height is 10 mm (0.4 in.). The multipurpose feeder can hold approximately:

• 100 sheets of 75 g/m

• 10 envelopes

• 75 transparencies

2

(20 lb) paper

Paper dimensions

The multipurpose feeder accepts paper within the following dimensions:

• Width—69.85 mm (2.75 in.) to 229 mm (9.01 in.)

• Length—127 mm (5 in.) to 355.6 mm (14 in.)

Trouble-free printing

• Load only one size of paper or envelopes at a time in the multipurpose feeder.

• To achieve the best possible print quality, use only high-quality print media that is designed for

use in laser printers. For more guidelines on paper, see Choosing print material.

• To prevent paper jams, do not add or remove paper when there is still paper in the

multipurpose feeder. This applies to other types of print materials, too.

• Never add print materials to the multipurpose feeder while the printer is printing from the

multipurpose feeder. Doing so may cause a paper jam.

• Print material should be loaded with the recommended print side up and the top of the print

material going into the multipurpose feeder first.

40

• Do not place objects on the multipurpose feeder. Also, avoid pressing down or applying

excessive force on it.

• Do not remove any paper tray while a job is printing from the multipurpose feeder or Busy is

displayed on the operator panel. Doing so may cause a paper jam.

Note: The multipurpose feeder may be used with the optional envelope feeder installed.

The icons on the multipurpose feeder show you how to load the multipurpose feeder with paper, how
to turn an envelope for printing, and how to load letterhead paper for simplex and duplex printing. If a
finisher is installed, it will affect how letterhead documents are loaded for duplexing. See Loading

letterhead for detailed instructions on loading documents printed on letterhead.

Loading the en velope f eeder

1 Gently adjust the envelope support for the size you are loading:

– Fully closed (pushed in toward the printer) for short envelopes
– Extended to the middle position for medium-length envelopes
– Fully open (extended to its full length) for long envelopes

WARNING: Do not place objects on the envelope feeder . Av oid pressing down on it or applying

excessive force.

2 Lift the envelope weight back toward the printer. It stays in place.

49

3

Slide the envelope edge guide to the far right.

4 Flex a stack of envelopes back and forth and then straighten the edges on a level surface.

Press down the corners to flatten them.

Fan the envelopes. This prevents the edges of the envelopes from sticking together and helps
them feed properly.

Note: When you load envelopes, do not exceed the maximum stack height of 64.7 mm

(2.55 in.). The envelope feeder holds a maximum of 85 envelopes (75 g/m
bond).

5

Load the stack of envelopes flap side down with the stamp area and the flap on the left. The
end of the envelopes with the stamp area enters the envelope feeder first. Let the envelopes
at the bottom of the stack slide into the envelope feeder slightly more than the ones at the top
of the stack.

WARNING: Never use envelopes with stamps, clasps, snaps, windows, coated linings, or

self-stick adhesives. These envelopes may severely damage the printer. See

Choosing envelopes for more information.

Note: Do not try to load more envelopes by forcing them under the envelope feeder

weight. This results in jams.

6 Slide the envelope edge guide to the left until it lightly touches the stack. Make sure the

envelopes do not buckle.

7 Lower the envelope weight to the stack.

51

8 Select the paper source, size, and type from your software application.
9 Select the paper size and type from printer operator panel:

a Make sure the Paper Size for the envelope feeder (Env Feeder Size) is set to the correct

envelope size you are loading. (See Paper Size for detailed information about this
setting.)

b Press Go to return to Ready.

Note: Software settings may override operator panel settings.

If envelopes jam, see Clearing paper jams.

Loading the 2000-sheet drawer

For information on loading the optional 2000-sheet drawer, refer to the
2000-Sheet Drawer User’s Guide on the Lexmark PRODUCT Publications CD that came with your
printer.

Tray linking

Tray linking enables the automatic linking feature for trays when you use the same size and type of
print material in multiple paper sources (trays).

For example, let’s say you have loaded two optional trays with the same size print material and both
are set to the same paper type. When one tray becomes empty, the printer automatically selects print
material from the other tray since the printer sees the trays as linked.

If you use different print material in the trays, each source with a different print material must have the
Paper Type set to a unique value to disable the automatic linking feature. If all the trays do not have the
same paper type when they are linked, you could mistakenly print a job on the wrong paper type.

Tips for a v oiding paper jams

By carefully selecting print materials and loading them properly, you should be able to avoid most
paper jams. If jams do occur, follow the steps outlined in Clearing paper jams. If jams occur
frequently, make sure you follow these tips to avoid jams:

• See Loading print material to load paper properly. Make sure the adjustable guides are

positioned correctly.

• Do not overload the paper trays. Make sure the paper is under the paper capacity mark on the

inside of the paper tray.

• Do not remove paper trays while print jobs are in process.

• Flex, fan, and straighten the paper before loading it.

• Fan stacks of labels or transparencies before loading them into trays or the multipurpose

feeder. If jams do occur using the multipurpose feeder, try feeding one sheet at a time.

• Do not load wrinkled, creased, damp, or curled paper.

• Do not mix paper types or paper sizes in one tray.

• Use only recommended print materials. See Recommended paper.

• Make sure the recommended print side is face down for simplex printing when loading all

trays.

• Keep print materials stored in an acceptable environment. See Moisture content.
