Service Safety Summary

Servicing Electrical Components

WARNING

Do not touch any electrical component unless you are instructed to do so by a service
procedure.

Figure 1 Electrical Components Warning

Before starting any service procedure, switch the printer power Off and unplug the power cord
f

rom the wall outlet. If you must service the printer with power app lied, be aware of the poten-

tial for electrical shock.

Servicing Mechanical Components

WARNING

Do not try to manually rotate or stop the drive assemblies while any printer motor is run­ning.

Electrostatic Discharge Pr ecautions

Some semiconductor components, and the respective sub-assemblies that contains them, are
vulnerable to damage by ESD. These co mponents include Integrated Circuits (ICs), Large­Scale Integrated Circuits (LSIs), field-effect transistors and other semiconductor chip compo­nents. The following techniques will reduce the occurrence of component damage caused by
static electricity.

Be sure the power is Off to the chassis or circuit board, and obser ve all other safety precau­tions.

• Immediately before handling any semiconductor components assemblies, drain the elec­trostatic charge from your body. This can be accomplished by touching an earth ground
source or by wearing a wrist strap device connected to an earth ground source. Wear ing
a wrist strap will also prevent accumulation of additional bodily static charges. Be sure to
remove the wrist strap before applying power to the unit under test to avoid potential
shock.

• After removing a static sensitivity assembly from its anti-static bag, place it on a grounded
conductive surface. If the anti-static bag is conductive, you may ground the bag and use
as a conductive surface.

• Do not use freon-propelled chemicals These can generate electrical charges sufficient to
damage some devices.

• Do not remove a replacement component or electrical sub-assembly from its protective
package until you are ready to install it.

• Immediately before removing the protective material from the leads of a replacement
device, touch the protective material to the chassis or circuit assembly into which the
device will be installed.

• Minimize body motions when handling unpacked replacement device. Motion such as
your clothes brushing together, or lifting a foot from a carpeted floor can generate enough
static electricity to damage an electro-statically sensitive device.

• Use tools specifically designed to remove or install IC’s and EPROM’s to avoid bending
pins.

• Pay attention to the direction of parts when mounting or inser ting them on the PCBs.

Figure 2 Mechanical Components Warning

When servicing mechanical components within the printer, manually rotate the Drive Assem­blies, Rollers, and Gears.

Servicing Fuser Components

WARNING

This printer uses heat to fuse the toner image to the media. Th e Fuser is ver y ho t. Turn
the printer power Off and wait at least 5 mi nutes for the Fu ser to co o l before attempting
to service the Fuser or adjacent components.

Electr ostatic Discharge Field Service Kit

The purpose of the Electrostatic Discharge (ESD) Program is to preserve the inherent reliability
and quality of electronic components that are handled by the Field Service Personnel. This
program is being implemented now as a direct result of advances in microcircuitry tec hnology,
as well as a new acknowledgement of the magnitude of the ESD problem in the electronics
industry today.

This program will reduce Field Service costs that are charged to Printed Wiring Board (PWB)
failures. Ninety percent of all PWB failures that are ESD related do not occur immediately.
Using the ESD Field Service Kit will eliminate these delayed failures and intermittent problems
caused by ESD. This will improve product reliability and reduce callbacks.

The ESD Field Service Kit should be used whenever PWBs or ESD sensitive components are
being handled. This includes activities like replacing or reseating circuit boards or connectors.
The kit should also be used in order to prevent additional damage when the circuit boards are
returned for repair.

The instructions for using the ESD Field Service Kit can be found in ESD Field Service Kit
Usage in the General Procedures section of the Service Manual.

The Phaser 5500/5550 printer combines a dual-pass, monochrome laser print engine with an
image processor supporting Adobe’s PostScript 3 description language. The PCL5e, PCL6
and Oak PCL 5.0 printer languages are als o supported. Print speed is 50 pages per minute at
either 600 x 600 or T rue 1200 x 1200 dpi in 1-sided or 2-sided modes. The printer features a bi­directional parallel interface and a USB port. The Phase r 5500/5550 printer provides a 100­sheet Tray 1/MPT from which specialty media, card stock, larger format paper, and envelopes
are fed. Tray 1 also supports manual feeding. Two additional trays, Tray 2 and 3, each provide
500 sheets of capacity. The Standard Output Tray holds 500 sheets face down.

Phaser 5500/5550 printer options add memor y, paper capacity and f unctionality. For models
not originally equipped, an internal Hard Drive is available fo r font storage, storing print files,
job collation, proof print and secure pr int support. A selection of RAM memor y upgrades are
available to raise th e installed quantity to the 1 GB maximum. A 1000-Sheet Feeder is avail­able with two, 500-sheet universal media trays (Trays 4 and 5). A 2000-Sheet Feeder (Tray 6)
brings the maximum input capacity to 4,100 sheets. An Envelope Tray, replacing Tray 2, is
available to feed envelopes. On the output side, a 3,500-sheet, high-capacity stapler/punch/
stacker is available rais ing the output total to 4000 sheets. A Configuration Card op tion adds
Ethernet 10/100/Gigabit baseTx networking to base models.

added to provide reverse drive. Electrical connection to the printer is made by an interface
cable.

Stacker / Finisher

The Stacker/Finisher increases the output capacity of the printer by 3,500 sheets. Printer out­put is directed to the Stacker/Finisher by w ay of Exit 1 and the Horizontal T ransport. With Exit 2
installed, the top surface of the Horizontal Transport serves as the top tray and paper output
capacity remains at 500 sheets. Depending on the level of Stacker/Finisher options and job
specifications, as paper enters the Stacker/Finisher it is punched, stapled, offset and stacked.
Control signals reach the Stacker/Finisher through a single connector. Power is supplied from
the printer’s AC Accessory Panel.

Overview

This chapter describes the printer’s self-diagnostic capabilities and includes methods to iden­tify and remedy reported printer problems. The diagnostic routines report problems using error
messages and fault codes displayed on the Front Panel, logged in the Service Usage Profile,
listed on the Startup Page or by flashing LEDs. These error indications serve as the entry point
into the troubleshooting process. Printer problems not directly indicated by or associated with
an error message or fault code are covered in Section 6, “General Troubleshooting.” Pr int­quality problems are covered in Section 3, “Image Quality.”

Error Message Summary

The Error Message Summary below lists possible error messages, along with, the correspond­ing Service Diagnostic message and Service Usage Profile fault code. The Control P anel Mes­sage column shows the message as is appears on the printer’s display when the error occurs
during normal operation. The Service Diagnostics’ err or message appears when errors occ ur
during testing. The Engine and Jam Errors columns list fault codes logged by the Service
Usage Profile, located in the Service Tools menu. The Go to Page column references the trou­bleshooting procedure related to the error.

Introduction

The error messages and codes generated by the printer’s operating system, the Service
Usage Profile, and Service Diagnostics are the lead-in to the troubleshooting procedures that
follow in subsequent pages. This section correlates the output of these three diagnostic aids
and provides the troubleshooting procedure to locate and correct reported errors.

Error Message Abbreviations

Due to limited display space, some error messages include abbreviations. The most common
abbreviations used throughout this section are listed here.

Using the Troubleshooting Procedures

1. Applicable Error Code(s) lists the error message(s) addressed by each troubleshooting
procedure.

2. Applicable Parts and References assist you in locating all the information avai lable for a
particular part or procedure. Remember that disassembly procedures, parts lists, and wir­ing diagrams for printer options appear in the Phaser 5550 Printer Options Service Man­ual.

3. Follow each Step in a troubleshooting procedure sequentially in the order given until the
problem is fixed or resolved.

4. The Actions and Questions box instructs you to perform a certain action or procedure.
Also included are precautions and/or additional procedures you must follow to isolate the
problem.

5. When a procedure instructs you to test a component using Service Diagnostics, see Ser­vice Diagnostics in section 6 for the detailed steps and functions for testing par ts of the
printer.

6. Each action is followed by a question. If your response to the question is “Yes”, then fol­low the instructions for a “Yes” reply. If your response to the question is “No”, then follow
the instructions for a “No” reply.

7. Note that two types of photo sensors are used: photo-reflective and photo-receptive.
Photo-reflective sensors use light reflected back from an object to detect its presence or
absence. Photo-receptive sensors use an actuator or the object itself to block the light
path to detect an object or condition.

8. Troubleshooting procedures frequently ask you to take voltage readings or test for conti­nuity or resistance at certain test points. The Reference table provides pointers to the dia­grams that provide this information.

9. Troubleshooting Procedures often ask you to replace a printer component. When
instructed to replace a non-spared com ponent and that component is part of a parent
assembly, replace the entire parent assembly.

Measurement Techniques

1. Unless indicated otherwise, the instruction “switch On printer main power” means for you
to switch On printer power and let the printer proceed through POST to a ‘Ready’ condi­tion.

2. When instructed to take voltage, continuity or resistance readings on wiring harness, pro­ceed as follows: Check P/J 232–1 to P/J 210–5 by placing the red probe (+) of your meter
on pin 1 of P/J 232, and place the black probe (–) of your meter on pin 5 of P/J 210.

3. When instructed to take resistance readings between “P/J 232 <=> P/J 210” (without
specified pin numbers), check all pins. See “Wiring Diagrams” for the location of all wiring
harnesses and pins.

4. Before measuring voltages make sure the printer is switched On, the Drum Cartridge and
the paper trays are in place, and the interlock switches are actuated, unless instructed
otherwise.

5. All voltages given in the troubleshooting procedures are approximate values. The pur­pose of voltage readings is to determine whether or not a component is receiving the cor­rect voltage and if gating (a voltage drop) occurs during component actuation. Gating
signals may be nothing more than a pulse, resulting in a momentar y drop in voltage that
may be difficult or impossible to read on the average multi-meter.

Unless otherwise specified, these voltage tolerances are used within this section:

T able 3 Volta ge Values

Stated Measured

+3.3 VDC +3.135 to +3.465 VDC
+5.0 VDC +4.75 to +5.25 VDC
+24.0 VDC +21.6 to +26.4 VDC

0.0 VDC Less than +0.5 VDC

Jam at A or F - F4-n H-Transport Exit Sensor ON

Paper activated the Horizontal Transport Entrance Sensor but did not reach the Horizontal
Transpor t Exit Sensor on time.

Intermittent “Jam At A” (F4-22) errors that occur on printers with a Finisher/Stacker installed,
that are characterized by the leading edge of the jammed sheet being in contact with the Hori­zontal Transport Belts may occur as a result of electrostatic discharges being generated as
paper passes through the Horizontal Transport. This sudden discharge interrupts t he Horizon­tal Transport Motor drive logic causing the motor to stall resulting in the jam.

For these special cases, a gasket kit has beed developed to provide a ground path from the
Horizontal Transport to the Finisher. This ground path eliminates static build up in the Horizon­tal Transport. Order part 604K28950, installation instructions are included in the kit
