Job names can be up to 16 alphanumeric characters and 
passwords must contain four numeric characters (0-7). 
PCL does not support leading zeros in the password. The 
printer assigns a default job name if no name or a name 
with a syntax error is used. The job name is displayed on 
the Control Panel Password Menu when the associated 
password is entered. If a password is not assigned or the 
password contains syntax errors, the job is not printed 
and is discarded.
The following example creates a Secure Job named 
“Bond” with a password of 7000:
%-12345X@PJL XSECUREJOB
@PJL XJOBPASSWORD = 7000
@PJL JOB NAME = Bond
@PJL ENTER LANGUAGE = PCL
...PCL file...
%-012345X@PJL EOJ
%-012345X
The printer processes all data following the @PJL ENTER 
LANGUAGE = PCL command as part of the Secure Job 
named “Bond.” The job is stored on the hard disk under 
the name “Bond” with a password of “7000” as defined in 
the @PJL XJOBPASSWORD command. The @PJL EOJ 
command signifies the end of the secure job. The EOJ 
command should be followed by a UEL command.

Creating Proof JobsProof printing lets you print a single copy of a multiple 
copy job. You assign a password and copy count at your 
workstation or computer before printing. The first set is 
printed immediately. You can then go to the printer and 
proofread (proof) the first set. Depending on the outcome 
of the proofing, you can then decide either to continue 
printing the remaining sets or to delete the job by 
entering the password at the printer’s Control Panel.
Proof jobs, if not sent by a driver with the proof job 
feature, may be invoked in both PCL and PostScript by 
preceding the job with the following PJL commands:
@PJL XPROOFJOB 
@PJL XJOBPASSWORD = number
These commands must be immediately followed by a 
standard PJL “JOB” command that includes the 
“jobname.”
The printer continues processing all subsequent data as 
part of the proof job of name “job name.” The proof job is 
stored with name “job name” and associated with the 
password defined in the PJL XPASSWORD command. The 
proof job ends when the PJL End of Job command is 
received (i.e., @PJL EOJ). The “EOJ” command should be 
followed by a UEL.

The job name is limited to 16 alphanumeric characters in 
the range ASCII 30 through ASCII 255,  and . 
The password must contain four numeric characters in 
the range ASCII 48 through ASCII 55. The printer assigns 
a default job name if no name or a name with a syntax 
error is called out. The job name is the name displayed on 
the Control Panel Password Menu when the associated 
password is entered. If no password is assigned or there is 
a password syntax error, the entire job is printed 
immediately and is not stored as a proof job.
The following example generates a PCL proof job with 
name “Sample” and associated with password “7777” 
requesting five collated sets.
%-12345X@PJL XPROOFJOB
@PJL XJOBPASSWORD = 7777
@PJL JOB NAME = Sample
@PJL SET QTY = 5
@PJL ENTER LANGUAGE = PCL
...PCL file...
%-012345X@PJL EOJ

Regular Printer Maintenance
Your DocuPrint NC60 is designed to need very little 
ongoing maintenance other than the replacement of 
maintenance items as they reach their end of use.
To avoid untimely image quality problems, we 
recommend that you replace maintenance items when 
the end of use warnings appear on the Control Panel. 
However, it is always good practice to periodically clean 
any loose toner or foreign matter in your printer. See the 
section “Cleaning the Printer” (page 4-4) for procedures and 
cautions.

Cleaning the Printer
The cleaning procedures described in this section will 
help you maintain the optimum print quality and 
minimize downtime of your DocuPrint NC60. Before you 
begin, be sure that you have a basic understanding of the 
parts of your printer. Also, pay strict attention to the 
cautions given in each process.
Cleaning the Print
Drum ChargerThe Print Drum Charger is a thin wire mesh used to place 
a charge on the Print Drum. If this mesh becomes dirty 
the Print Drum will not obtain a proper charge resulting 
in image quality defects. To clean the Print Drum Charger, 
follow these steps.
1Open the front and top covers of the printer and locate 
the Print Drum.
2On the top left side of the Print Drum you will see a green 
thumb tab. This is the Print Drum Charger cleaner slide. 
3Simply slide this Print Drum Charger cleaner slide back 
and forth several times and return it to its original 
location.

Cleaning the
Grounding Roller and
Feed RollersThe interior rollers, located under the Front Cover, should 
be cleaned only if roller marks appear on prints.

There is a small paper sensor switch in the bottom of the 
printer that is easily broken. Use extreme caution in this 
area to avoid damaging the printer. This switch can 
only be repaired by a service technician.
When cleaning, do not use water or a cloth dampened 
with water. Use a clean, dry, lint free cloth.

Follow these steps to clean the rollers.
1Raise the Front cover.
2Locate the Print Drum.
When removing and inserting the Print Drum, do 
not allow the green drum to touch any parts of the 
printer. Contact may damage the delicate drum 
degrading print quality.
3Release the latches on both sides of the Print Drum.
4Grasp the Print Drum by the handles and slide it up and 
out of the printer, being careful to not allow the drum to 
come into contact with the front cover of the printer.
The Print Drum is sensitive to prolonged exposure 
to bright light. If the drum is exposed to excessive 
light (the average fluorescent office lighting) for 
more than 2 minutes, it may require up to 2 hours 
of darkness to recover. Extended exposure will 
cause permanent damage.
5Set the Print Drum Module aside on several sheets of used 
paper and cover the drum with several layers of paper to 
avoid light contact.
6Locate the paper sensor switch in the bottom of the 
printer. See diagram above. Take care not to damage this 
switch while cleaning.
