Introduction
This troubleshooting chapter assumes the reader has a basic understanding of the color
laser printing process. Explanations of each mechanical assembly, printer system, and the
basic theory of operation are found in Chapter 5. Do not perform any of these
troubleshooting processes without fully understanding the function of each mechanism.
This chapter contains the following sections:
www.partshere.com
Ɣ
Troubleshooting process includes a pre-troubleshooting checklist and a
troubleshooting flowchart. These tools contain information about common printer errors
that can inhibit proper operation or create print quality problems. These tools also
include recommendations for solving the cause of the error.
Ɣ
Printer error troubleshooting explains each control panel display message and
suggests recommendations for clearing the cause of each message. When the printer
message indicates a failure for which the root cause is not obvious, use the printer error
troubleshooting section and the troubleshooting tools section found later in this chapter
to solve the problem.
Ɣ
Paper path troubleshooting provides techniques to solve feed problems. Explanations
regarding print media checks, troubleshooting jams, and the differences between jams
caused by media and those caused by the printer are discussed.
Ɣ
Image formation troubleshooting suggests methods for solving print quality problems.
Ɣ
Interface troubleshooting provides techniques for isolating communication problems to
the printer hardware, printer configuration, network configuration, or software application.
Ɣ
Control panel troubleshooting provides procedures for printing a menu map from the
printer control panel. It also describes the control panel menus, the items within each
menu, and the possible values for the menu items.
Ɣ
Troubleshooting tools help isolate the cause of printer failures. This section includes
explanations of the printer configuration page and the event log.
Ɣ
Diagnostics provides instructions on how to access and use the diagnostic tools
incorporated into the printer.
Ɣ

Troubleshooting process
When the printer malfunctions or encounters an unexpected situation, the printer control
panel alerts you of the situation. This section contains a pre-troubleshooting checklist to filter
out many possible causes of the problem. A troubleshooting flowchart helps you diagnose
the root cause of the problem. The remainder of this chapter provides steps for correcting
problems.
Ɣ
Use the pre-troubleshooting checklist to evaluate the source of the problem and to
reduce the number of steps required to fix the problem.
Ɣ
Use the troubleshooting flowchart to pinpoint the root cause of hardware malfunctions.
The flowchart guides you to the appropriate section of this chapter that provides steps
for correcting the malfunction.
Before beginning any troubleshooting procedure, check the following:
NOTE
Ɣ
Are supply items within their rated life?
Ɣ
Does the configuration page reveal any configuration errors?
The customer is responsible for checking supplies and for using supplies that are in good
condition.

NOTE
If the printer’s display is blank, but the power-on checks pass, try printing an engine test
page to determine whether the problem is with the engine/display or with the formatter. See
Engine test page for instructions.
Troubleshooting power-on
When you turn on the printer, if it does not make any sound or if the control panel display is
blank, check the following items:
1. Verify that the printer is plugged into an active electrical outlet with the correct voltage
and not plugged into a surge protector or power strip.
2. Verify that the on/off switch is in the ON position.
3. Make sure the fan is running, indicating the system is operational.
4. Verify that the firmware DIMM (HP 3700 only) and the formatter are seated and
operating properly.
5. Remove any HP Jetdirect or other devices, then try to turn the printer on again.

Printer error troubleshooting
The following tables explain messages that might appear on the printer control panel.
Alphabetical printer messages and their meanings are listed in the Table 7-2. Alphabetical
printer messages table, and numerical printer messages are listed in the Table 7-3.
Numerical printer messages table.
NOTE
Not all messages are described in the tables; those messages that are not listed are selfexplanatory.
Status messages
Status messages reflect the current state of the printer. They inform you of normal printer
operation and require no interaction to clear them. They change as the state of the printer
changes. Whenever the printer is ready, not busy, and has no pending warning messages,
the status message Ready is displayed if the printer is online.
Warning messages
Warning messages inform you of data and print errors. These messages typically alternate
with the Ready or Status messages and remain displayed until the button is pressed. If
CLEARABLE WARNINGS is set to Job status = in the printer’s configuration menu, these
messages are cleared by the next print job.
Error messages
Error messages communicate that some action must be performed, such as adding paper or
clearing a paper jam.
Some error messages are auto-continuable. If AUTO CONTINUE=ON is set in the menus,
the printer will continue normal operation after displaying an auto-continuable error message
for 10 seconds.
NOTE
Any button pressed during the 10-second display of an auto-continuable error message will
override the auto-continue feature, and the function of the button pressed will take
precedence. For example, pressing the STOP button will cancel the job.
Critical error messages
Critical error messages inform you of a device failure. Some of these messages can be
cleared by turning the printer off and then on. These messages are not affected by the auto
continue setting. If a critical error persists, service is required.
The following table lists and describes control panel messages in alphabetical order.

Four color slippage bands occur

tab is out of position. This can
cause interference with the yellow
cartridge, where the cleaning blade
shipping tab contacts the OPC
white plastic hub and the OPC
ground contact adjacent to the OPC
hub. This interference between the
cleaning blade and the yellow
cartridge prevents the proper
engagement between the ITB drive
roller coupler and the engine ITB

Perform the following steps to fix the

yellow toner cartridge for any damage.
If either the yellow cartridge or the ITB

Measure the gap between the ITB and
the metal bracket at the bottom end
(where the ITB makes contact with the
yellow cartridge, below the recycling

A critical firmware error has
occurred that caused the processor
on the formatter to abort operation.
This type of error can be caused by
invalid print commands, corrupt
data, or invalid operations. In some
cases, electrical noise in the cable
can corrupt data during
transmission to the printer. Other
causes include poor quality parallel
cables, poor connections, or homegrown applications. On rare
occasions, the formatter is at fault,
which is usually indicated by a

Replacement parts configuration
When the parts in the list below are replaced, specific tasks need to be performed. These
parts include:
Ɣ
Formatter and DC Controller replaced at the same time
Ɣ
Formatter (new and previously installed in another printer)
Ɣ
DC Controller (new and previously installed in another printer)
Ɣ
Media sensor (PS5)
Ɣ
Color Misregistration Sensor (PS12)
Ɣ
Laser Scanner Assembly
Ɣ
Fuser
Ɣ
Transfer unit (ITB assembly)
Configuration procedures for these parts are described in the following sections.
Formatter and DC Controller replaced at the same time
Do not replace both the formatter and the DC Controller at the same time. Replace one
at a time. If the formatter and DC Controller are replaced at the same time in an HP Color
LaserJet 3700 series printer that has the ability to perform duplex printing, this functionality
will be lost. To determine if the printer can duplex, print a configuration page from the
INFORMATION menu and reference Paper Trays and Options. If Duplex Unit is listed, the
printer is able to duplex and the formatter and DC Controller should be replaced one at a
time.
If the DC Controller and Formatter are replaced one at a time, then the duplex printing
capability will be transferred to the new DC controller or Formatter.
A printer specific PJL file will be needed to re-enable duplexing in the current printer (will not
work on any other printer), if both the formatter and DC Controller are replaced at the same
time. This file will only work in the current printer. Call for assistance from HP Support to
obtain the PJL file. Also, perform the Formatter and DC Controller replacement steps as
required below.
Formatter (New) replacement configuration
The values for Total Mono Pages, Total Color Pages, Serial Number, Service ID, Cold Reset
Paper (if needed), and the Fuser Kit Count will need to be reset using the service menu.
NOTE
The Transfer Kit count will be unaffected by the replacement of a formatter.
Print a configuration page and a supplies status page in the INFORMATION menu to obtain
the page counts, counts for any of the supplies, serial number, and the born-on date. If a
configuration page and a supplies status page cannot be printed, this information can be
obtained from the Service menu prior to replacing the formatter.
To ensure optimum print quality, the printer will need to be calibrated by performing 3
Calibrate Now's using the printer control panel by selecting CONFIGURE DEVICE / PRINT
QUALITY / CALIBRATE NOW.

Formatter (previously installed in another printer)
replacement configuration
When the formatter PCB is being replaced with one that was installed in another printer, an
NVRAM initialization will need to be performed. Before doing an NVRAM INIT, print a
configuration page and a supplies status page in the INFORMATION menu to obtain the
page counts, counts for any of the supplies, serial number, and the born-on date. If a
configuration page and a supplies status page cannot be printed, this information can be
obtained from the Service menu prior to replacing the formatter or performing this action.

Paper path troubleshooting
Jam error messages occur if paper fails to arrive at or clear the paper path sensors in the
allowed time. Dedicated paper sensors detect whether paper is present in the sensor and if
paper is fed normally. When the DC controller detects a jam, it immediately stops the printing
process and displays the appropriate jam message for the sensor that detects the jam. The
location of all paper path sensors is shown in the figure below.

General paper path troubleshooting
Use the following suggestions to isolate the cause of the problem. Once you have identified
the cause, use the tables that follow to find a recommended solution.
NOTE
Use the paper path test in the Diagnostics menu to print pages while troubleshooting. See
Paper Path Test section later in this chapter for information about the paper path test.
Ɣ
View or print the event log and determine if a particular jam error occurs more often than
others. Try to identify a pattern.
Ɣ
From the event log, determine the frequency of a particular jam. If a jam occurs
repeatedly around the same page count, consider this a single jam that the customer
tried to clear.
Ɣ
Try printing from all available input trays to identify whether the problem is isolated to
one tray.
Ɣ
Print the job in both simplex and duplex modes to identify if the problem occurs only in
one mode or the other.
Ɣ
Try printing on paper from an unopened ream that has been stored correctly. If the jam
does not occur with this media, then the customer’s media might be causing the problem.
Ɣ
If the jam occurs from when the printer is turned on, check the paper path for small torn
pieces of paper. Also check for broken sensors or flags, and check for loose or defective
connections.
Ɣ
If the paper is torn, folded, or wrinkled (typically along the leading edge), inspect the
paper path for items that could be causing the damage.
Ɣ
If the customer is using non-HP supplies, try replacing those supplies with genuine
HP supplies to see if the problem goes away.
Ɣ
If necessary, instruct the customer on proper media storage, correct loading technique,
and printer operation. Make sure the customer knows not to grab paper in the output bin
during duplex printing.
Paper path checklist
www.partshere.com
Ɣ
Verify that media is correctly loaded in the input trays and that all length and width
guides are set correctly.
Ɣ
Clean the printer. Toner and paper dust in the paper path can inhibit free movement of
media through the printer and can block the sensors.
Ɣ
Use the paper path test in the Diagnostic menu to vary the input selections of the printer
to determine if the problem is associated with a particular area of the printer.
Ɣ
Worn rollers or separation pads can cause multifeeds. Check the condition of the pickup
rollers and separation pads.
Ɣ
Defective paper sensors along the paper path might signal a false jam.
Ɣ
Scraps of media left in the paper path can cause intermittent jams. Always check that
the paper path is clear when cleaning the printer and when clearing jams. Also, remove
the fuser and carefully check it for jam debris.
Partshere Troubleshooting
Persistent jams
If jams occur repeatedly, use the information in this section to diagnose the root cause of the
problem. The tables in this section list possible causes and recommended solutions for jams
in each area of the paper path. Items are listed in the order you should investigate. In
general, items at the beginning of the list are relatively minor repairs. Items at the end of the
list are more significant repairs.
Basic troubleshooting for paper jams
The basic troubleshooting process for paper jams consists of the following:
1. Gather data.
2. Identify the cause of the problem.
3. Fix the problem.
Data collection
To troubleshoot paper jams, gather the following information:
www.partshere.com
Ɣ
the exact paper jam error code displayed on the control panel
Ɣ
the location of the leading edge of the paper in the paper path
Ɣ
whether paper is in the paper path when the jam occurs, or if paper is stuck in the input
tray
Ɣ
whether the jam occurs at power-up or while paper is moving
Ɣ
whether the paper is damaged, and if it is, where the damage occurs on the paper and
where in the paper path the paper stops
Ɣ
whether the jam occurs when feeding from one particular tray
Ɣ
whether the jam occurs only when duplex printing
Ɣ
whether a particular type of paper is jamming or not jamming
Ɣ
whether any of the supplies are non-HP (non-HP supplies are known to cause paper
jams)
Ɣ
whether the customer is storing the paper correctly, overloading the trays, damaging the
edge of the paper during loading, or using paper that has already been fed through the
printer
Partshere Troubleshooting
Image formation troubleshooting
The section identifies some things that can result in poor print quality. For additional
information, refer to the HP LaserJet Printer Family Print Media Guide.
Print quality problems associated with media
Some print quality problems arise from use of inappropriate paper.
Ɣ
Use paper that meets HP paper specifications. See Supported media weights and sizes.
Ɣ
The surface of the paper is too smooth. Use paper that meets HP paper specifications.
See Supported media weights and sizes.
Ɣ
The driver setting is incorrect. To change the paper type setting, see Type and Size.
Ɣ
The paper you are using is too heavy for the paper type setting you selected, and the
toner is not fusing to the paper.
Ɣ
The moisture content of the paper is uneven, too high, or too low. Use paper from a
different source, from an unopened ream of paper, or dry out the paper (100˚ C for 24
hours).
Ɣ
Some areas of the paper reject toner. Use paper from a different source or from an
unopened ream of paper.
Ɣ
The letterhead you are using is printed on rough paper. Use a smoother, xerographic
paper. If this solves your problem, consult with the supplier of your letterhead to verify
that the paper used meets the specifications for this printer. See Supported media
weights and sizes, in chapter 1.
Ɣ
The paper is excessively rough. Use a smoother, xerographic paper.
Overhead transparency defect
Overhead transparencies can display any of the image quality problems that any other type
of paper will cause, as well as defects specific to printing on transparencies. In addition,
because transparencies are pliable while in the print path, they are subject to being marked
by the paper-handling components.
NOTE
www.partshere.com
Allow transparencies to cool for at least 30 seconds before handling them.
Ɣ
Change the pre-rotation setting in the CONFIGURE DEVICE/PRINT QUALITY/
OPTIMIZE/PRE-ROTATION=ON. This will enhance transparency print quality by
reducing what looks like “fire marks” by heating up the fuser pressure roller closer to the
temperature of the sleeve.
Ɣ
Change the transparency mode in the CONFIGURE DEVICE/PRINT QUALITY/PRINT
MODES/TRANSPARENCY to B TRNSPRNCY (Best Transparency) mode. This change
will optimize transparency print quality and minimize transparency curl.
Partshere Troubleshooting
NOTE
If the printer’s media sensor rejects a supported Color LaserJet transparency, make sure the
transparencies are not from an old box. Try transparencies from a new box.
Ɣ
In the printer driver Paper tab, select Transparency as the paper type. Also, make sure
that the tray is correctly configured for transparencies.
Ɣ
Check that the transparencies meet the specifications for this printer. See Supported
media weights and sizes, in chapter 1. For more information on media specifications and
ordering information, consult the HP LaserJet Printer Family Print Media Specification
Guide. For the HP Color LaserJet 3500/3550 series printer, go to http://www.hp.com/
support/clj3550. For the HP Color LaserJet 3700 series printer, go to http://www.hp.com/
support/clj3700. For downloadable manuals, select Manuals.
Ɣ
The transparencies you are using are not designed for proper toner adhesion. Use only
transparencies designed for HP Color LaserJet printers.
Ɣ
Handle transparencies by the edges. Oil from fingers can cause spots and smudges on
the transparencies.
Ɣ
Small, random, dark areas on the trailing edge of solid fill pages may be caused by
transparencies sticking together in the output bin. Try printing the job in smaller batches.
Ɣ
The selected colors are undesirable when printed. Select different colors in the software
application or printer driver.
Ɣ
If you are using a reflective overhead projector, use a standard overhead projector
instead.
Print quality problems associated with the environment
If the printer is operating in excessively humid or dry conditions, verify that the printing
environment is within specifications. See the getting started guide for this printer for
information on operating environment specifications.
Print quality problems associated with paper jams
Make sure that all paper is cleared from the paper path.
Ɣ
If the printer recently jammed, print two to three pages to clean the printer.
Ɣ
If the paper does not pass through the fuser, which causes image defects to appear on
subsequent documents, print two to three pages to clean the printer. However, if the
problem persists, see Print quality troubleshooting pages.
Print quality problems associated with toner buildup
Over time, toner and other particles can build up inside the printer. This buildup can cause
the following print quality problems:
Ɣ
marks at even intervals on the printed side of the page
Ɣ
toner that smears easily
Ɣ
toner specs on the page
Ɣ
vertical streaks or bands on the page
To correct these types of problems, clean the printer. See Cleaning the printer and
accessories, in chapter 4.

combination of automatic color features to generate excellent color results for the general
office user. Also, the HP Color LaserJet 3700 series printer provides sophisticated tools for
the professional who is experienced with using color.
The HP Color LaserJet 3500/3550 series printer and HP Color LaserJet 3700 series printer
provide carefully designed and tested color tables to provide smooth, accurate color
rendition of all printable colors.
HP ImageREt 2400
HP ImageREt 2400 is a technology that provides the best color print quality without having
to change printer driver settings or make trade-offs between print quality, performance, and
memory.
HP ImageREt 2400 has been improved for this printer. The improvements offer trapping
technologies, even greater control over dot placement, and more precise control of toner
quality in a dot. These new technologies, coupled with HP's multilevel printing process,
result in a 600-by-600 dpi printer that provides 2400 dpi color laser-class quality with millions
of smooth colors.
Paper selection
For the best color and image quality it is important to select the appropriate paper type from
the software printer menu or from the printer control panel. See Selecting paper, in chapter 1.
Color options (available for the HP Color LaserJet 3700
series printer)
Color options automatically enable optimal color output for diverse types of documents.
Color options use object tagging, which allows optimal color and halftone settings to be used
for different objects (text, graphics, and photos) on a page. The printer driver determines
which objects are used on a page and uses halftone and color settings that provide the best
print quality for each object. Object tagging, combined with optimized default settings,
produces great color out of the box.
In the Windows environment, the Automatic and Manual color options are on the Color tab in
the printer driver.
Standard red-green-blue (sRGB)
Standard red-green-blue (sRGB) is a world-wide color standard originally developed by
HP and Microsoft as a common color language for monitors, input devices (scanners and
digital cameras), and output devices (printers and plotters). It is the default color space used
for HP products, Microsoft operating systems, the World Wide Web, and most office
software sold today. The sRGB standard is representative of the typical Windows PC
monitor today and the convergence standard for high-definition television.
www.partshere.com
Partshere Troubleshooting
NOTE
Factors such as the type of monitor you use and the room’s lighting can affect the
appearance of colors on your screen. For more information, see Managing color.
The latest versions of Adobe PhotoShop®, CorelDRAW, Microsoft Office, and many other
applications use sRGB to communicate color. Most importantly, as the default color space in
Microsoft operating systems, sRGB has gained broad adoption as a means to exchange
color information between applications and devices using a common definition that ensures
typical users will experience greatly improved color matching. The sRGB standard improves
your ability to match colors between the printer, the PC monitor, and other input devices
(scanners and digital cameras) automatically, without the need to become a color expert.
Printing in four-colors [CMYK (available for the HP Color
LaserJet 3700 series printer)
Cyan, magenta, yellow, and black (CMYK) are the inks used by a printing press. The
process is often called four-color printing. CMYK data files are typically used by and
originate from graphic arts (printing and publishing) environments. The printer will accept
CMYK colors through the PS printer driver. The printer color-rendering of CMYK is designed
to provide rich, saturated colors for text and graphics.
CMYK ink set emulation (PostScript only)
The printer’s color rendering of CMYK can be made to emulate several standard Offset
Press ink sets.
Ɣ
Default. This selection is good for general purpose rendering of CMYK data. It is
designed to render photographs well, while at the same time providing rich saturated
colors for text and graphics.
Ɣ

Partshere Troubleshooting
Managing color
Setting color options to Automatic will typically produce the best possible print quality for
color documents. However, there may be cases when you want to print a color document in
grayscale (black and white) or wish to change one of the printer's color options.
Using Windows, print in grayscale or change the color options using settings found on the
Color tab in the printer driver.
Using a Macintosh computer, print in grayscale or change the color options using the Color
Matching pop-up menu in the Print dialog box.
Print in Grayscale
Selecting the Print in Grayscale option from the printer driver prints a document in black and
white. This option is useful for printing color documents that will be photocopied or faxed.
When Print in Grayscale is selected, the printer goes into monochrome mode (regardless of
what the COLOR/BLACK MIX setting is). This mode will reduce wear on the color cartridges.
Automatic or manual color adjustment
The Automatic color adjustment option optimizes the neutral gray color treatment, halftones,
and edge enhancements used for each element in a document. For more information, see
your printer driver online Help.
NOTE
Automatic is the default setting and is recommended for printing all color documents.
The Manual color adjustment option allows you to adjust the neutral gray color treatment,
halftones, and edge enhancements for text, graphics, and photographs. To access the
Manual color options, from the Color tab, select Manual, and then Settings.
Manual color options
Manual color adjustment allows you to adjust the Color (or Color Map) and Halftoning
options individually for text, graphics, and photographs.
NOTE
Some applications convert text or graphics to raster images. In these cases, the
Photographs settings will also control text and graphics.
Halftone options affect the resolution and clarity of your color output. You can select
halftone settings for text, graphics, and photographs independently. The two halftone options
are Smooth and Detail.
For the HP Color LaserJet 3700 series printer, the following options are available for the
Halftone setting:
www.partshere.com
Ɣ
The Smooth option provides better results for large, solid-filled print areas. It also
enhances photographs by smoothing out fine color gradations. Choose this option when
uniform and smooth area fills are top priority.
Ɣ
The Detail option is useful for text and graphics that require sharp distinctions among
lines or colors, or images that contain a pattern or a high level of detail. Choose this
option when sharp edges and details are top priority.
Partshere Troubleshooting
The Neutral Grays setting determines the method used for creating gray colors used in text,
graphics, and photographs.
For the HP Color LaserJet 3700 series printer, the following options are available for the
Neutral Grays setting:
Ɣ
Black Only generates neutral colors (grays and black) using only black toner. This
guarantees neutral colors without a color cast.
Ɣ
4-Color generates neutral colors (grays and black) by combining all four toner colors.
This method produces smoother gradients and transitions to non-neutral colors, and it
produces the darkest black.
The Edge Control (for the HP Color LaserJet 3500/3550 series printer) setting determines
how edges are rendered. Edge control has two components: adaptive halftoning and
trapping. Adaptive halftoning increases edge sharpness. Trapping reduces the effect of color
plane misregistration by overlapping the edges of adjacent objects slightly.
NOTE
Selecting this setting may significantly slow down the HP Color LaserJet 3500/3550 series
printer’s speed.
For the HP Color LaserJet 3700 series printer, the following levels of edge control are
available:
Ɣ
Maximum is the most aggressive trapping setting. Adaptive halftoning is on for this
setting.
Ɣ
Normal is the default trapping setting. Trapping is at a medium level and adaptive
halftoning is on.
Ɣ
Light sets trapping at a minimal level, and adaptive halftoning is on.
Ɣ
Off turns off both trapping and adaptive halftoning.
For the HP Color LaserJet 3500/3550 series printer, the following levels are available:
Ɣ
Maximum is the most aggressive trapping setting.
Ɣ
Normal sets the trapping at a medium level.
Ɣ
Light sets trapping at a minimal level.
Ɣ
Off is the default trapping setting. Trapping is turned off.
For the HP Color LaserJet 3700 series printer, the following values are available for the RGB
Color settings:
www.partshere.com
Ɣ
Default instructs the printer to interpret RGB color as sRGB. The sRGB standard is the
accepted standard of Microsoft and the World Wide Web Consortium (http://www.w3.org).
Ɣ
Vivid instructs the printer to increase the color saturation in the midtones. Less colorful
objects are rendered more colorfully. This value is recommended for printing business
graphics.
Ɣ
Device instructs the printer to print RGB data in raw device mode. To render
photographs properly with this selection, you must manage image color in the
application or operating system.
Partshere Troubleshooting
Matching colors
The process of matching printer output color to your computer screen is quite complex
because printers and computer monitors use different methods of producing color. Monitors
display colors by light pixels using an RGB (red, green, blue) color process, but printersprint
colors using a CMYK (cyan, magenta, yellow, and black) process.
Several factors can influence your ability to match printed colors to those on your monitor.
These factors include:
Ɣ
print media
Ɣ
printer colorants (inks or toners for example)
Ɣ
printing process (inkjet, press, or laser technology for example)
Ɣ
overhead lighting
Ɣ
personal differences in perception of color
Ɣ
software applications
Ɣ
printer drivers
Ɣ
PC operating system
Ɣ
monitors
Ɣ
video cards and drivers
Ɣ
operating environment (humidity for example)
Keep the above factors in mind when colors on your screen do not perfectly match your
printed colors.
For most users, the best method for matching colors on your screen to your printer is to print
sRGB colors.
Swatch book color matching (HP Color LaserJet 3700 series
printer only)
The process for matching printer output to preprinted swatch books and standard color
references is complex. In general, you can obtain a reasonably good match to a swatch
book if the inks used to create the swatch book are cyan, magenta, yellow, and black. These
are usually referred to as process color swatch books.
Some swatch books are created from spot colors. Spot colors are specially created
colorants. Many of these spot colors are outside of the gamut (color range) of the printer.
Most spot color swatch books have companion process swatch books that provide CMYK
approximations to the spot color.
Most process swatch books will have a note on what process standards were used to print
the swatch book. In most cases, they will be SWOP, EURO, or DIC. To get optimal color
matching to the process swatch book, select the corresponding ink emulation from the
printer menu. If you cannot identify the process standard, use SWOP ink emulation.
For best matching of PANTONE® four-color (4C) process colors, use the SWOP or EURO
emulation for CMYK inks in the HP Color LaserJet 3700 PostScript emulation driver when
printing from PANTONE®-certified applications.

the printer’s four toner colors. The available range for each color is from -5 to +5. The default
value is 0.
CAUTION
This procedure should only be performed by your network administrator. Performing this
procedure changes the color balance of the printer by altering halftones and affects all print
jobs.

Repetitive defects troubleshooting
Defects on printer rollers can cause image defects to appear at regular intervals on the
page. Use the repetitive defects ruler, see Figure 7-4. Repetitive defects ruler following the
table on the next page, to measure the distance between defects that recur on a page. Use
Table 7-39. Repetitive defect cause table, below, to determine which roller is causing the
defect. To resolve the problem, try cleaning the roller first. If the roller is still dirty after
cleaning or if it is damaged, replace it.
CAUTION
Do not use solvents or oils to clean rollers. Instead, rub the roller with lint-free paper. If dirt is
difficult to remove, rub the roller with lint-free paper dampened with rubbing alcohol.
NOTE
Defects on the Tray 2 pickup roller or the multipurpose tray pickup roller do not cause a
repetitive defect. Defects on these rollers cause a defect to appear only on the leading edge

This section contains information about printer communication troubleshooting.
Communications checks
NOTE
Communication problems are normally the customer’s responsibility. Time spent attempting
to resolve these problems might not be covered by the product’s Hewlett-Packard warranty.
Refer the customer to the network administrator for assistance in troubleshooting network
problems.
If the printer is not connected to an MS-DOS-based host, proceed to Table 7-40.
Communications check, Communications check.
Table 7-40. Communications check
Check
Action
Is your computer configured
to the parameters described
in the configuration
instructions?
These parameters are required to communicate with the printer.
Verify that the configuration of the computer's communications
port matches these parameters.
NOTE
If these parameters are not set properly, an error might display on
the control panel.
EIO troubleshooting
If the printer contains an optional HP Jetdirect print server, and you cannot communicate
with the printer over the network, verify the operation of the print server. Print a configuration
page. If the Jetdirect card does not appear under “Installed personalities and options” on the
configuration page (indicated by the arrow in ), see the troubleshooting section of the
HP Jetdirect Print Server Software Installation Guide.
If the host system and printer are still not communicating, replace the formatter PCB and the
EIO card and reconfigure the printer. If the problem persists, a protocol analyzer might be
needed to find the source of the problem.

Partshere Troubleshooting
CAUTION
HP LaserJet printers are not designed to work with mechanical switch-box products without
proper surge protection. These devices generate high transient voltages that cause
permanent damage to the formatter PCB. This circumstance is not covered by the HewlettPackard warranty.

Printer Job Language (PJL) commands
See the HP Printer Job Language Technical Reference Manual for a complete description of
PJL commands. This manual is available with the HP PCL/PJL Reference Set on CD-ROM,
part number 5021-0337.
@PJL [Enter]
This command enables the specified printer language. If the printer does not receive this
command it enables the default language. This ensures the correct operation applications
that do not support PJL. The command syntax is:
www.partshere.com
Partshere Troubleshooting
@PJL [Enter] LANGUAGE = {PCL/PostScript} [<CR>] <LF>
UEL (universal exit language)
This command (also referred to as the universal exit language command) terminates the
current printer language and returns control to PJL. It performs the following actions:
Ɣ
Prints all data received before this command.
Ɣ
Performs a reset: <esc>E in PCL, <cntrl>D in PostScript.
Ɣ
Turns control over to PJL.
This command is also a valid HP-GL/2 terminator.
The UEL command must be immediately followed by the “@PJL” command prefix.
Characters or control codes other than @PJL (such as <CR> or <LF>), enable the default
language and process the print job in that language. All jobs must begin and end with the
UEL command. Besides entering PJL, the UEL command has the same effect as the
<esc>E command. However, the <esc>E command should always be included to ensure
backward compatibility.
@PJL COMMENT
This command designates the current line as a comment, which is ignored. The syntax is:
@PJL COMMENT <words> [<CR>] <LF>
@PJL INFO CONFIG
This command solicits a response to describe the installed options and allows the printer to
configure the installed options automatically as the applications require.
@PJL INFO ID
This command identifies the printer type to the host for reference when selecting printer
drivers for automatic installation. The command syntax is:
@PJL INFO ID <CR> <LF>
@PJL INFO USTATUS
This command queries the state of unsolicited JOB status. PAGE and TIMED status are not
supported. The syntax is:
@PJL INFO USTATUS <CR> <LF>
@PJL INFO PAGECOUNT
This command returns the number of pages printed by the engine.
www.partshere.com
Partshere Troubleshooting
@PJL JOB
This command informs the printer of the start of a PJL job and synchronizes the job status
information. The printer counts print jobs, including nested jobs, incrementing the job counter
for the @PJL JOB command and decrementing it for @PJL EOJ.
The printer accepts the NAME= parameter and returns the name string in the unsolicited
JOB start status message (if unsolicited job status is enabled). The printer transmits the
unsolicited JOB status message to every I/O channel that has enabled this function. This
message’s format is:
@PJL USTATUS JOB <CR><LF>
START<CR><LF>
[NAME=<job name><CR><LF>]
<FF>
The printer resets the nested job counter whenever it switches the source to a different I/O
channel. This prevents a corrupt job on one channel from disrupting the activities on another
channel.
@PJL EOJ
This command identifies the end of a print job and is a hint for the I/O switching algorithm.
The printer counts nested jobs and recognizes job boundaries when the counter decrements
to zero. The printer ignores isolated EOJ commands. Each EOJ must be preceded by a JOB
command.
@PJL ECHO
This printer supports the ECHO command which transmits its parameters over the I/O
channel to the host that issued the command.
@PJL USTATUS JOB=ON/OFF
This command enables or disables the JOB status for the I/O channel that delivers the
command.
@PJL USTATUSOFF
This command disables the unsolicited JOB status for the I/O channel that delivered the
command. For this printer, it duplicates the function of @PJL USTATUS JOB=OFF, AND
@PJL USTATUS DEVICE=OFF.
NOTE
www.partshere.com
All commands not supported by this printer’s PJL command set are returned with the
message @PJL XXXX<CR><LF>?<CR><LF>.

Engine diagnostics
This section provides an overview of the engine diagnostics incorporated into the HP Color
LaserJet 3500/3550 and 3700 series printer. The printer contains extensive internal
diagnostics that help in troubleshooting print quality issues, paper path issues, noise issues,
component issues, and timing issues.
Diagnostics mode
Some of the diagnostic tests automatically put the printer into a special diagnostics mode.
The special diagnostics mode allows the printer to perform actions that it normally could not
because the printer would enter an error state. Always follow the control panel directions in
the Diagnostic menu to properly exit the special diagnostics mode and return the printer to a
normal state.
Diagnostics that put the printer into special diagnostics mode
There are four diagnostic tests that put the printer into a special state:
Ɣ
Disable cartridge check
Ɣ
Paper path sensor test
Ɣ
Manual sensor test
Ɣ
Component test
While the printer is in the special diagnostics mode, the display should read:
Ready Diagnostics Mode
To exit press Stop KEY
www.partshere.com
Partshere Troubleshooting
When the printer is in the special diagnostics mode, the four tests listed above appear in the
menu and are available to be run. To access other diagnostic tests or to leave the special
state, press the STOP button, and then select Exit diagnostics. The printer will reset itself,
and then return to the normal state.
NOTE
A good understanding of how the printer operates is required to use the engine diagnostics
successfully. Before proceeding with these diagnostic tests, be sure you understand the
information in Chapter 5 of this manual.
Diagnostics tests
Different tests can be used to isolate different types of issues. For component or noise
isolation, you can run the diagnostics with the left, right, and rear covers removed. Do not
operate the printer with the front door open. Operating the printer with the front door open
will cause the gears on the right side of the printer to become out of sync with the front door.
Upon closing the front door, the gears on the right side and print cartridges can be damaged.
WARNING!
www.partshere.com
Take caution when performing printer diagnostics to avoid risk of injury. Only trained service
personnel should access and run the diagnostics with the covers removed. Never touch any
of the power supplies with the printer turned on.

Disable Cartridge Check – special mode test
This diagnostic test allows you to print internal pages or sends an external job to the printer
with one or more print cartridges removed or swapped. Because the cartridges are not
keyed, the diagnostic test can be run with one to four cartridges removed or swapped to
another location. Consumable supply errors are ignored while in this mode. Once in this
mode, you can navigate the menus and print internal pages or send an external print job to
the printer. This diagnostic test can be used to isolate print quality problems related to
individual cartridges and to isolate individual cartridge problems such as noise.
NOTE
Do not remove or swap cartridges before entering the disable cartridge check diagnostic.
After entering the test, you can remove or swap cartridges.
While performing the disable cartridge check, you can navigate the menus and print internal
pages as desired from the control panel. Use the button to access the menus as you
normally would. You can also send external print jobs to the printer.
To exit this diagnostic, press the STOP button and then select EXIT diagnostics.
Paper Path Sensors – special mode test
This test allows you to test the printer’s sensors for proper operation. Each sensor is
represented by a letter, as indicated in the table below. A one below the letter on the display
indicates paper is present. This test allows you to print internal pages or send an external
job to the printer. This test will also test the new Media sensor (PS5) which senses OHT,
Gloss, Gloss Film, and Plain paper.
Manual Sensor Test – special mode test
This test allows you to manually test paper path sensors and the door open switch. Each
sensor is represented by a letter, as indicated in the tables below.

Clear event log
This item allows you to clear the printer’s internal event log.
Total page count
The page count stored in NVRAM and printed on the configuration page represents the
number of pages that the formatter has formatted (not including engine test prints). If you
install a new formatter when repairing a printer, use this menu item to reset the page count
to the previous value. In this way, the page count reflects the number of pages printed by the
engine rather than starting over for the new formatter. The page count is broken into two
categories: total mono pages and total color pages.
Transfer kit count
This value can be changed in the service menu but it will not change the value of the
transfer kit. This value is initially set to zero at the factory. This value is automatically reset to
zero when a customer installs a new transfer kit and sets NEW TRANSFER KIT to YES in
the Resets menu.
If only the formatter is replaced, the transfer kit page count will not be lost.
Fuser kit count
This item allows you to reset the fuser count if the value is lost, such as when you replace
the formatter. This value is initially set to zero at the factory. Enter a value up to 60,000 for
the hp 3500 and 75,000 for the HP 3700/3550. This value is automatically reset to zero
when a customer installs a new transfer kit and sets NEW FUSER KIT to YES in the Resets
menu.
Serial number
If you replace the formatter, use this item to reset the serial number of the printer.

Service ID
This item allows the date that the printer was first used to be shown through the control
panel, eliminating the need for customers to keep paper receipts for proof of warranty.
Because the printer does not have an internal clock, the service ID date’s availability is
dependent on the printer being connected to a source that can provide the date, such as the
installer, the driver, or the embedded Web server. In cases where the printer is not
connected to a date source, the service ID will not be available, and the control panel will
display 000000.
Restoring the Service ID
If you replace the formatter, the date is lost. Use this menu item to reset the date to the
original date the printer was first used. The date format is YYDDD. Calculate the date as
follows:
1. To calculate YY, subtract 1990 from the calendar year. For instance, if the printer was
first used in 2002, calculate YY as follows: 2002 – 1990 = 12. YY = 12.
2. To calculate DDD, use the following formula: 30(calendar month – 1) + calendar day =
DDD. If the calendar day is 31, use 30 instead. For instance, if the printer was first used
on October 17, calculate DDD as follows:
3. Subtract 1 from 10 (October is the tenth month of the year): 10 – 1 = 9.
4. Multiply 9 by 30: 9 x 30 = 270.
5. Add 17 to 270: 270 + 17 = 287. Thus, DDD = 287.
Converting the Service ID to an actual date
You can use the printer’s Service ID number to determine whether the printer is still under
warranty. Convert the Service ID into the installation date as follows:
1. Add 1990 to YY to get the actual year that the printer was installed.
2. Divide DDD by 30. If there is a remainder, add 1 to the result. This is the month.
3. The remainder from the calculation in step 2 is the date.
Using the Service ID 12287 as an example, the date conversion is as follows:
1. 12 + 1990 = 2002, so the year is 2002.
2. 287 divided by 30 = 9 with a remainder of 17. Since there is a remainder, add 1 to 9 to
get 10, which represents October.
3. The remainder in step 2 is 17, so that is the date.
4. The complete date is 17-October-2002.
NOTE
A 6-day grace period is built into the date system.
Cold reset paper
When you perform a cold reset, the paper size stored in NVRAM is reset to the default
factory setting. If you replace a formatter board in a country/region such as Europe that uses
A4 as the standard paper size, use this menu to reset the default paper size to A4. LETTER
and A4 are the only available values.
