5Holding a job in the printer
When sending a job to the printer, you 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. We
recommend a minimum of 32MB available printer memory and a hard disk.
To learn more about this function, click a topic:
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 Printing 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
• Printing and deleting held
jobs
• Recognizing when format
errors occur
• Verifying print jobs
• Reserving print jobs
• Accessing held jobs from
the operator panel
• Repeating print jobs at a
later time
• Printing confidential jobs

14
Accessing held jobs from the operator panel
1To access held jobs from the operator panel:
–If the printer is Busy, press Menu. The Job Menu appears.
–If the printer is Ready, continue to step 2.
2Press Menu until you see Held Jobs or Confidential Job on the operator panel display,
depending on the type of job you want to access.
3Press 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.
4Press Menu until you see your user name.
Note: If you are looking for a Confidential Job, you are prompted to enter your PIN. See
Printing confidential jobs for more information.
5Press Select.
6Press 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).
7Press 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.
8Press 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.

15
Repeating print jobs
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.
Reserving print jobs
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.
Verifying print jobs
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.

16
Printing 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 memory until
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
=____
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.
If you enter an invalid PIN, the message No Jobs Found. Retry? appears. Press Go to reenter the
PIN, or press Stop to exit the Confidential Job menu.
When you enter a valid PIN, you have access to all print jobs matching the user name and PIN you
entered. The print jobs matching the PIN you entered appear on the display when you enter the Print A
Job, Delete A Job, and Print Copies menu items. You can then choose to print or delete jobs matching
the PIN you entered. (See Printing and deleting held jobs for more information.) After printing the
job, the printer deletes the confidential job from memory.

6Paper and specialty media
specifications
The following table lists supported paper and specialty media sizes and weights for the standard and
optional trays, as well as for the multipurpose feeder. We recommend that you try a limited sample of
any paper or specialty media you are considering using with the printer before purchasing large
quantities.
The following sections contain guidelines for choosing the correct print media for your printer.
Paper
For the best print quality, use 75 g/m2(20 lb) xerographic, grain long paper. Try a sample of any paper
you are considering using with the printer before buying large quantities.
When loading paper, note the recommended print side on the paper package, and load paper
accordingly. See Loading the trays and Loading the multipurpose feeder for detailed loading
instructions.

The following papers are not recommended for use with your printer:
•Paper with a rough or heavily textured surface
•Coated papers, such as erasable bond
•Preprinted papers manufactured with chemicals that may contaminate the printer
•Multiple-part forms
•Synthetic papers
•Thermal papers
•Recycled paper having a weight less than 75 g/m2(20 lb)
Letterhead
Preprinted papers such as letterhead must be able to withstand temperatures up to 200°C (392°F)
without melting or releasing hazardous emissions. Use inks that are not affected by the resin in toner
or the silicone in the fuser. Inks that are oxidation-set or oil-based should meet these requirements;
latex inks might not.
Printing on letterhead
Check with the manufacturer or vendor to determine whether the preprinted letterhead you have
chosen is acceptable for laser printers.
To load letterhead in the:
•paper trays, see Loading the trays, page 22
•multipurpose feeder, see Loading the multipurpose feeder, page 29
Transparencies
You can feed transparencies from any of the trays. Try a sample of any transparencies you are
considering using with the printer before buying large quantities.
To load transparencies in the:
•paper trays, see Loading the trays, page 21
•multipurpose feeder, see Loading the multipurpose feeder, page 28
When printing on transparencies:
•Be sure to set the Paper Type to Transparency from the printer driver.
•Use transparencies designed specifically for laser printers. Transparencies must be able to
withstand temperatures of 175°C (347°F) without melting, discoloring, or releasing hazardous
emissions.
•To prevent print quality problems, avoid getting fingerprints on the transparencies.
•Before loading transparencies, fan the stack to prevent sheets from sticking together.
•To avoid jams, remove each transparency as it exits into the output bin.

19
Labels
Your printer can print on many labels designed for use with laser printers. These labels are supplied in
letter size and A4 size sheets. Label adhesives, face sheet (printable stock), and topcoats must be able
to withstand temperatures of 205°C (401°F) without melting or releasing hazardous emissions and
pressure of 25 pounds per square inch (psi).
Try a sample of any labels you are considering using with the printer before purchasing a large
quantity.
Card stock
Card stock is single ply, and has a large array of properties, such as the orientation of paper fibers and
texture, that can significantly affect the print quality.
Try a sample of any card stock you are considering using with the printer before purchasing a large
quantity.
When printing on card stock:
•Set the Paper Type to Card Stock from the printer driver.
•Do not use preprinted card stock manufactured with chemicals that may contaminate the
printer. Preprinting introduces semi-liquid and volatile components in the printer.
•Do not use card stock that is perforated or creased. It may cause print media jams.
•We recommend the use of grain short card stock.
For detailed information on label printing, card stock printing, characteristics, and design, refer to the
Card Stock & Label Guide available on Lexmark’s Web site at www.lexmark.com/publications.

7Linking trays
•If you load the same size and type of paper or media in more than one tray, the printer
automatically links the trays. This means that when one tray is empty, it feeds from the next
linked tray.
For example, if you have the same size and type of paper or media loaded in tray 2 and tray 3,
the printer feeds from tray 2 until it becomes empty, and then it feeds from the next linked
tray—tray 3.
•If you load the same size paper or media in each tray, make sure it is also all the same type to
link the trays.
Once the trays you selected are loaded with the same size and type of paper or media, select
the same Paper Type setting in the Paper Menu for these sources.
•To disable tray linking, set the Paper Type to a unique value in each one of the trays.
