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.

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
