1.5 Memory Options
1.5 Memory Options
Font memory is an area of printer memory that stores downline-loaded fonts.
Once stored in font memory, the font stays until the printer is powered down.
Print jobs that downline-load many fonts expand the size of font memory until
memory overflow errors occur.
To deal with memory overflow errors, customers can increase font memory by
installing single in-line memory modules (SIMMs) or an optional hard disk
assembly.
1.5.1 Optional Hard Disk
The optional hard disk expands font memory by 127 non-volatile MB. The
downline-loaded fonts remain in the printer through power cycles. Storing
fonts on the disk leaves the RAM free for other needs.
The disk is customer installable and the disk formatting procedure is automatic
and interactive. See the following locations for additional information:
•
Section 4.11 contains the formatting procedure.
•
Section 6.11 contains the hard disk display messages and FIP.
•
Section 9.6 contains the hard disk assembly removal and replacement
procedure.
1.5.2 Expansion Memory
The video controller board has two expansion memory (SIMM) slots. Each
slot can hold a 4-, 16-, or 32-MB SIMM. The additional RAM increases the
available RAM to the video controller board. See the removal/replacement
procedure in Section 9.14 to install a SIMM.

1.8 Resolution/Graphics Enhancements Option Board
1.8 Resolution/Graphics Enhancements Option Board
The optional Resolution/Graphics Enhancements (RGE) board is installed in a
connector on the video controller board. The connector socket is located above
the two SIMM sockets.
RGE image enhancement differs from DECimage enhancement. RGE creates
a 1200 x 1200 bit map in the video controller board memory; DECimage uses
a 600 x 600 dpi bitmap. This memory usage might cause memory overflow or
print overrun errors (described in Section 6.8) when printing complex images
or using many downline loaded fonts.
The RGE enhances the appearance of all PostScript and PCL images. Low
resolution image enhancement begins as soon as the RGE board is plugged in
and power is turned on. It cannot be enabled or disabled. Two high-resolution
features are available:
•
1200 x 600 dpi
•
1200 x 1200 dpi

2.1.1 Video Controller Board and SmartPage
Figure 2–2 shows the video controller board mechanically and electronically
connecting and interfacing to the following standard and optional devices:
Standard devices:
•
The AppleTalk, parallel, and serial interface ports that allow direct
simultaneous connections to three different host computers
•
The operator panel provides users with control and status
•
The DC control board which operates the print engine
Optional devices:
•
One or two font cartridge
•
Optional hard disk drive
•
Optional XLI image enhancement board
•
Optional Ethernet network card
The video controller board accepts PostScript level 2 or PCL5E code files
from either the host or Ethernet interfaces and creates a bitmap image. The
bitmap is fed to the DC controller board as the V DO signal that is described in
Section 2.4.
Traditionally, an entire page is bitmapped into RAM before the printer is
commanded to feed and print. Such a system requires a considerable amount
of RAM memory.
SmartPage is the name of the process that the DEClaser 5100 printer uses to
create the printed image. Instead of bitmapping an entire page, this printer
bitmaps in bands. When one band is complete, it prints while the next band is
bitmapping. The SmartPage process uses about one-sixtieth as much RAM as
a full page bitmap requires.
2–4 Technical Description
2.1 Print Engine Control
Occasionally, a complex image might exceed the capabilities of the SmartPage
process, or memory might overflow due to insufficient memory. When
SmarPage fails, the printer:
•
Displays a memory overflow or print overrun error message
(See Section 6.8
•
Fails to print from the point of error to the end of the sheet
•
Continues to print until the job is finished

2.1 Print Engine Control
2.1.2 Print Engine Modes
Figure 2–3 shows the activity that occurs during the following DEClaser 5100
operational modes:
1. When the printer is powered on, the printer enters the wait mode and:
•
Turns on the fusing heater and monitors the temperature rise.
•
Checks the top door and rear door closed sensors
•
Makes sure the selected feeder is installed and loaded
•
Checks the EP-ED cartridge and toner empty signal
•
Runs the main and scanner motors
•
Turns the high-voltage bias supplies on and off
•
Cleans the transfer roller
2. If all the wait checks pass, the printer enters standby STBY mode
until a print request is received. During standby, fusing temperature
and interlocks are maintained. Standby ends when a print command is
received from the video controller or from the test print switch.
3. After a PRNT signal is received, the printer enters the initial rotation
(INTR mode) which lasts approximately six seconds. During this period
the fusing temperature is raised, the main and scanner motors come
up-to-speed, and the print drum stabilizes.
2–6 Technical Description
2.1 Print Engine Control
4. During print mode, the fusing temperature is maintained, interlocks are
tested, and printing is performed.
5. During the last rotation mode (LSTR) the last page of the job is ejected
and the transfer roller is cleaned. If a PRNT signal is received during this
mode, then initial rotation mode immediately begins.

2.1.3 Low-voltage Power Supply Assembly
Figure 2–4 shows the circuits of the low-voltage power supply assembly
(LVPSA). If a short circuit or other fault draws excessive current from the
+24VA or +5V regulators, the output voltage decreases to a minimal level. To
reset the regulator, power the printer off and then on again.
The circuit breaker reset button is accessible through a hole on the side of the
LVPSA. The circuit breaker opens when a short circuit occurs in the LVPSA.
A shorted power regulator output should not trip the circuit breaker.
Note: A 6.3 amp fuse is used in place of the circuit breaker of power supplies
that carry the Sanken label.
When the top door is closed, the top door switch provides the +24VB to the
motors and high-voltage supplies.
Section 2.1.4 describes the operation of the fusing heater control circuit and
the THOUT , RLD , and FSRD signals.

2.1 Print Engine Control
2.1.4 Fusing Heater Control
Figure 2–5 shows how the fusing temperature varies after power and during
printing and standby operations.
Figure 2–7 shows the circuitry that controls the fusing temperature. The
surface temperature of the upper fusing unit roller is measured by thermistor
(TH1) and adjusted by the DC control board.
The fusing temperature sets the resistance of TH1, establishing the voltage
level for the analog FSRTH signal. The resistance of TH1 decreases as the
fusing temperature increases. The following TH1 resistance readings are
measurable across pins 1 and 2 of the fusing unit connector (J743):
•
Room temperature resistance of TH1 is approximately 239K .
•
Operating temperature resistance of TH1 is less than 2.0K
.

2.1 Print Engine Control
2.1.5 Fusing Malfunction
If a fusing malfunction occurs, dynamic and passive safety circuits disable the
fusing heater current.
The safety circuit opens RL101 and disconnects the fusing current if the:
•
Fusing temperature fails to reach 172°C (341.6°F) within 200 seconds of
power on, the DC control board asserts RLD .
•
Fusing temperature rises above the maximum high temperature
•
Fusing temperature falls below the minimum low temperature.
•
A short circuit occurs in the fusing heater or leads. The LVPSA senses the
increased current and forces the safety circuit to open RL101.
If an uncontrollable temperature rise occurs, the thermoswitch (TP1) opens to
permanently disconnect the fusing current.
When a fusing error occurs, C202 is charged to approximately +5 Vdc,
which prevents the operation of the fusing circuit. C202 discharges only
when the power is turned off. If power is turned on before the charge is
completely drained, C202 fully recharges. The printer must remain off for
approximately 10 minutes.
Caution: If you do the following, be sure to power off the printer and disconnect
the power cord. For service reasons only, C202 can be discharged by touching
the + lead of C202 to the metal chassis ground frame. Failure to power off the
printer can damage the DC control board.

2.2 Paper Feeding System
Paper can feed from the cassette underneath the printer, or from the front tray
or envelope feeder at the front of the printer. The paper feed unit mechanically
and electrically controls all media feeding.
•
The front tray can feed paper, envelopes, labels, and single sheets.
•
The envelope feeder holds about 55 envelopes.
•
The internal or optional LCIT cassettes feed only standard sized cut sheets,
listed in Table 2–1.
2–12 Technical Description
2.2 Paper Feeding System
Before the feed process can start, the user must first load and select a feeder.
When the print job is received, the video controller sends a PRNT signal to
the DC control board. If the engine is in standby mode, a short pause occurs
while the fusing unit warms up and initial rotation (INTR) occurs. Finally, the
feed process can start.

The two oblique rollers drive the sheet forward and sideways into the left side
plate and then into the registration sensor . This action deskews the sheet
squarely aligning it with the axis of the print drum.

When the paper triggers the registration sensor, the paper feed motor pauses
to allow the print drum to rotate into alignment
with the leading edge of the
sheet. When these are aligned, the paper feed motor starts and feeds the sheet
into the transfer point.

The paper is supported by the oblique rollers which move the sheet through the
transfer and static elimination areas and into the nip of the fusing rollers .

The ac and dc biases on the primary

across the Organic photoconductor
(OPC) drum. The ac bias is applied to
keep the primary charge even across the
surface of the print drum.

Density can be adjust to obtain a darker print by concurrently changing both
the primary and development dc bias. The development dc bias is described in
Section 2.3.3.
The primary charging roller is made of a conductive foam rubber-like compound
and is part of the EP-ED cartridge. The foam roller charging system requires
less high-voltage bias and produces less ozone then corona type charging
systems used on other printers.
As the OPC drum turns, the primary charge is subjected to the exposure
process.

Charge
The data modulated scanning laser
beam paints a latent image on the
rotating OPC drum. Where the laser
exposes the drum, the existing primary
charge is neutralized. The primary
charge remains in the unexposed areas.
This exposure system is commonly
referred to as a write black system.
The areas exposed to the laser light
correspond to the black areas of the
printed image. The unexposed areas
retain the primary charge, failing to
attract toner to the drum during the
development process.

On the OPC drum, the highly charged unexposed areas repel the toner. The
lesser charged, or exposed areas are painted with the toner, thus making the
image visible to the naked eye.
The developer dc bias varies from the primary dc bias (see Section 2.3.3).

Roller
In the transfer process, the toner image
is attracted from the OPC drum to the
sheet of paper by the highly charged
transfer charging roller. The transfer
roller is made of a conductive foam
rubber-like compound.
During normal printer operation, the
porous surface of the transfer charging
roller attracts a small amount of toner,
which can degrade the quality of the
image. To purge this toner, a reverse
polarity is applied during initial rotation
(INTR) and between sheets. Frequent
jamming and other malfunctions can
overwhelm the transfer charging roller
purging process and cause image defects.

2–18 Technical Description
After the toner image is transferred
and the sheet travels to the fusing unit,
residual toner is cleaned from the OPC
drum surface.
After the transfer process, the toner
image is loosely held to the paper sheet
by electrostatic and adhesive forces.
At this stage, all of the toner could be
brushed off the page.
As the sheet passes between the upper
and lower fusing rollers, the toner melts
and is pressed into the sheet, thus
making a permanent image.
2.3 Xerographic Process
The two diodes connect the axial shafts to ground and establish a strong
negative cleaning charge on the upper roller. The upper metal fusing roller
accumulates the charge from the residual transfer charge that adheres the
unfused toner to the sheet. This negative charge repels the like-charged toner
particles from the upper roller thus making it difficult for the toner to stick to
the fusing rollers.
The nonstick coating on the upper roller also helps prevent toner from sticking.

2.4 Scanner
2.4 Scanner
Figure 2–10 shows the circuits and components within the scanner assembly.
When the printer is powered on, the DC control board generates the scanner
clock (SCNCLK ) signal that regulates the speed of the scanner motor. The
scanner motor does not run until a print command is received.
When V SY NC is received, the DC control board asserts the following signals
to turn on the scanner and laser:
•
•
•
SCANON to run the scanner motor
ENBL to enable the laser diode
LON to force the laser diode on
When the scanner motor is up-to-speed, the scanner ready (SCNRDY ) signal
is sent to the DC control board. The following conditions cause a scanner
motor error:
•
•
SCNRDY
SCNRDY
fails to assert within 20 seconds of SCON .
negates (goes high) for longer then 2.5 seconds while the
scanner motor is running.
When the scanning beam passes the beam detect (BD) mirror, it reflects the
light into the beam detector, creating the BDI signal. The DC control board
receives BDI and sends BD to the video controller board.
In response to BD , the video controller transmits the video data out (V DO )
signal to the DC control board, which sends it to the laser driver as the
V DAT A signal.
The automatic power control (APC) regulates controls the intensity of the laser
light.
To start the laser the DC control board first asserts the LON signal, then
incrementally increases the value of the APC output (APCOUT ) signal. This
action slowly turns the laser on.
When the laser is on, a portion of the laser light strikes the adjacent photodiode
and creates the APC input (APCIN ) signal. APCIN feeds back to the DC
control board, which uses it to control APCOUT and thus stabilize the
intensity of the laser beam.

2.5 HVPSA
2.5 HVPSA
Figure 2–11 shows the high-voltage bias circuits that are used by the
xerographic processes discussed in Section 2.3. Not shown in Figure 2–11 is
the HVPSA/fuser interconnect that makes connection to the DC control board.
Figure 2–12 photographically shows the locations of the high-voltage terminals.
The HVPSA communicates with the DC control board through the serial SL02
and SLI 2 signal lines. IC402 is a communication gate array that provides
two-channel serial interface to IC202 on the DC control board.
IC401 is a custom integrated circuit that provides the following:
•
The ac bias coupled with dc bias used by the primary and development
processes. The dc component varies according to laser beam intensity
and to the setting of the user assessable density adjustment. The HVPSA
couples this dc component to the development bias.
•
The transfer bias switches from negative for cleaning and to positive for
printing.
•
The static eliminator removes the residual transfer charge from the paper
sheet.
•
TB402 and the contact plate capacitor provide an ac ground path for the
transport entrance guide.
The HVPSA contact plate mechanically connects the HVPSA to the EP-ED
cartridge and contains the transfer roller and static eliminator. The coil
and flat springs of the contact plate press against metal contact pads on the
HVPSA circuit boards. The spring holding pressure comes from the screws and
clips that are used to mount the HVPSA and contact plate.

Before using the start FIP, do the following:
•
Record the symptoms, then recycle/reboot the printer.
•
Do all steps of the start FIP shown in Table 5–1.
•
Follow the FIPs in order. The printer is not fixed until you complete the
start FIP with no errors.
•
After fixing the original malfunction, perform the TCC procedures listed in
Section 5.3 to make sure no other problems exist.
•
Keep the following in mind when the FIP tells you to check a signal or
power supply voltage:
–
Unless otherwise stated, all voltage readings should be within ±5% of
the stated value.
–
Voltage level ‘‘low’’ means 0 to +0.5V.
–
Voltage level ‘‘high’’ means 5V ±0.5V.
–

Error Message FIPs
The TCC procedure involves inspecting
for damage and worn out parts and
involves cleaning the inside and outside
of the printer. Performing the TCC
procedure can reduce the number of
service calls.
To clean the paper path, use a clean lint-free cloth and the special vacuum
cleaner specified in Section D.3. Use a damp sponge to clean the covers and
external components.
While cleaning, look for broken plastic or metal components or for any signs of
damage. Replace any damaged components.
Before ending a service call, make sure you have done the following:
1. Discuss the operation of the printer with the customer.
2. If more then 200,000 sheets have printed, perform the 200K maintenance
procedure (see Section 5.3.1).
The page count appears when you select the Show page count feature from
the Test/fonts key menu. See Figure A–1 for more information.
3. Power on the printer.
4. Either print several test prints or have the customer print a multipage job
to exercise the printer for a prolonged time period (5 minutes or more).
5. If intermittent problems or mixed problems occur, note down the type of
problem. See Table 5–1 start FIP for a pointer to the specific FIP.
6. Inspect all the paper path rollers for:
•
Surface contamination, uneven wear, dirt, or damage
•
Broken or disconnected pressure springs
•
Defective or unsecured bearings

6.1 Bad Power or Control Panel FIPs
Explanation: A power or control panel malfunction can cause a failure of the
normal power up activities. Because the control panel is inoperative, there are
no error messages.
When the printer is working properly, you can see and hear the following
events after the power is turned on:
Sounds
Air wooshing from the exhaust fan, high-pitched whine from the scanner
motor, low-pitched rumble from the main motor and gear train.
Control
panel
Various indicators light as the self test runs, the "Warming Up" message
appears for approximately 200 seconds, and the "READY/IDLE" message
appears at the end of the power-up process.
Action
The main motor turns (rounding) the paper path rollers for approximately
six seconds. If the covers are removed, you can see the fuser heater
glowing.
Review the following two sets of symptoms and choose the one that describes
the malfunction:
Symptom 1: The following symptoms indicate a working print engine with a
malfunctioning control panel circuit:
•
At power up, the rounding cycle completes
•
The fusing unit gets warm
•
The engine board test pattern prints.
•
The control panel message is blank, hung, unreliable, or ambiguous.
Action: Do the following to fix a control panel problem:
1. Make sure that the control panel cable connector is properly plugged into
the J131 connector on the video controller board. See Section 9.2 for the
connector’s location and Section 2.1.1 for a block diagram.
2. Swap the following FRUs:
•
Video controller board
•
Control panel
•
DC control board

6.1 Bad Power or Control Panel FIPs
Symptom 2: The following symptoms indicate a malfunctioning ac power line
or low-voltage power supply assembly (LVPSA):
•
The printer blows the fuse or circuit breaker that supplies the AC line
power.
•
No normal power up sounds, rounding, or roller motion
•
The control panel display and indicators are blank and never turn on.
•
The printer runs for a short time then shuts down or is intermittent.
Action: Do the following to fix a power problem:
1. Try another ac line plug and swap the power cord.
2. If the ac wall power is bad, call the site electrician to restore power.
3. Remove the right side panel and metal card cage.
Refer to Figure 6–1 for connector and pin numbers mentioned in the
following steps.
4. Inspect the 6-wire cable that runs from the DC control board to the J103
connector on the LVPSA. Make sure it is properly plugged in and in good
condition.
5. Remove the video controller board and all optional equipment.
6. Press the test print switch to see if the printer can print or use a VOM to
measure the power supplies from the LVPSA on J103.
7. Skip the following and go to step 8 if the printer fails to print or if the
VOM fails to measure +5 and +24 Vdc.
•
Replace the video controller board and removed options one at a time
to find the bad FRU.
•
If the power failure is intermittent, inspect the two SIMM memories.
The use of nonspecified third-party SIMMs can cause power problems,
but only if the printer is fully equipped with all possible optional
equipment.

6.2 Optional Equipment Non-Error FIPs
6.2 Optional Equipment Non-Error FIPs
When the Test (power up) Page builds in memory, the video control board
checks for installed options. Each option is listed as installed or not installed
on the printed sheet. The sheet also lists the amount of installed memory. See
Section 4.1 for information about the Test Page.
If any of the options that you know are installed, fail to list on the Test Page,
swap or replace the option or the connecting FRUs to diagnose and repair the
problem. The following is a list of the optional equipment:
•
The envelope feeder is powered by and communicates with the paper feeder
control board. Feed failures and paper jams are typical envelope feeder
problems.
•
The hard disk is mounted on, powered, and operated by the video controller
board. Section 6.11 lists all the hard disk error messages.
•
There are two independent SIMM sockets on the video controller board. If
only one SIMM is installed, it can mount in either socket. If two SIMMs
are installed, they can be of different sizes and installed in any order.
Memory is available, from Digital Equipment Corporation, in 4-, 16-,
or 32-Mb SIMM boards. A customer can purchase and install standard
personal computer memory. The SIMMs must comply to the following
requirements:
•
32-bit wide, non-parity, 72-pin SIMMs that conform to JEDEC
Standard 21.
•
36-bit wide, parity, 72-pin SIMMs such as the PC74M-AA/AB/AC
•
The 4-, 8-, and 16-Mb SIMMs are described as single bank, fast-pagemode read/write memory with cas-before-Ras refresh
The Test Page lists the available RAM. 2-Mb is built in and each installed
SIMM adds to this number. For example, if you had installed a 16-Mb and
a 4-MB SIMM, you will see 22-Mb of RAM on the Test Page.
If a SIMM is bad, that entire SIMM’s memory will fail to list on the Test
Page. For example, if you installed 16-Mb and 4-Mb SIMMs and you saw
6-Mb of RAM on the Test Page, you would know that the 16-Mb SIMM is
bad or incorrectly installed.
•
The LCIT mounts under the printer. It is powered by and communicates
with the feed controller board. Most LCIT malfunctions result in feed
failures or jams.

6.2 Optional Equipment Non-Error FIPs
•
The Font (PCMCIA) cartridges plug into connectors on the video controller
board. Try moving the cartridge to the opposite slot. See the insert or
remove FIP in Section 6.3
•
The Resolution/Graphics Enhancements (RGE) board is socket mounted
on the video controller board. Low resolution image enhancement begins
as soon as the RGE board is plugged in and power is turned on. It cannot
be enabled or disabled. The two high-resolution features (1200 x 600 and
1200 x 1200 dpi) are enabled from the host system or through the Setup
key menu. See Appendix A for more information about the key menus and
Section 1.8 for more information about the RGE.
•
The Ethernet network board connects to a socket mounted on the video
controller board.
When power is turned on the Ethernet board’s self-test runs. If the self-test
passes, a status sheet (not shown in this service guide) is printed. On the
status sheet you can find the following:
•
The Ethernet address.
•
The setting of the twisted pair/ThinWire jumpers.
•
Information for the various types of networks.
The rear panel green LED does the following:

6.8 Memory Overflow or Print Overrun
6.8 Memory Overflow or Print Overrun
One of the following messages appears when the SmartPage process fails:
Print overrun
The SmartPage coprocessor failed to complete the current band
before additional data arrived from the host.
Memory overflow
While building the page, the printer ran out of memory.
limitcheck
A PostScript error that prints on a PostScript error sheet but is
not displayed on the control panel.
It is very unlikely that a hardware malfunction could cause these error
messages without some other error message. If you suspect the hardware is
faulty, swap the video controller board or memory SIMMs.
SmartPage failures occur when the customer prints pages that are too complex
for the SmartPage process.
To correct SmartPage errors, advise the customer to:
•
Invoke the page protect mode. This forces the printer to build a full page
in memory before printing occurs and slows down the completion of the
print job.
Page protect is invoked from the PostScript or PCL Set-Up key menu, as
shown in Appendix A.
•
Disable the do jam recovery feature. If enabled, jam recovery uses a large
amount of memory.
•
Reduce print resolution through the host software or through the
PostScript or PCL submenu of the Set-Up key menu, as shown in
Appendix A.
•
Add additional SIMMs to increase the amount of RAM memory.
For additional information see Chapter 7 of the DEClaser 5100 Printer User’s
Guide.

6.9 No Toner Cart or Toner Low
6.9 No Toner Cart or Toner Low
Explanation: The toner sensor circuit detects both the presence of a toner
cartridge and quantity of toner that remains.
The ac signal from the developer roller travels through the toner to the toner
sensor, which acts like an antenna. The strength of the signal received by the
toner sensor varies with the quantity of toner in the EP-ED cartridge.
The HVPSA measures the toner signal and determines the quantity of toner
or whether an EP-ED cartridge is installed. Toner is measured during the
development portion of the xerographic process. EP-ED cartridge checks are
performed during power up, after top door closing, or control panel keying.
Signal diagram reference: See Figures 6–5 and 2–11 for wiring diagrams.
Action: Do the following:
1. The toner might be damp. Remove the EP-ED cartridge and shake it to
loosen up the toner.
2. Swap the EP-ED cartridge with a known good unit.
3. Inspect the toner sensor contacts on the EP-ED cartridge and the connector
block. Replace any damaged parts.
4. Make sure the HVPSA is correctly installed. Both hold down screws must
be tight and the clips must be holding. See Section 9.4 for installation
instructions.
5. Remove the HVPSA and inspect the TB403 spring contact.
6. Swap the following FRUs:
•
DC control board
•
HVPSA
•
HVPSA/Fuser Interconnect
•
HVPSA contact plate guide
Power and Control Panel FIPs 6–13
6.10 Printer Open
6.10 Printer Open
Explanation: This message appears when the top door of the printer is open.
When the top door is closed, a tang attached to the door presses down the
two-pole door open switch. One pole shorts DOPEN to ground. Pole two
connects +24VA supply to the +24VB.
The plastic tang on the closed top door depresses the linkage spring, which
presses the black plastic stud, which depresses the door open switch. The
switch is soldered on the paper feed controller board. The black plastic stud is
mounted on the paper feed unit housing. If the top door fails to properly latch,
the pressure from the linkage and the switch lever springs is strong enough to
hold open the top door.
To clear this error, close the top cover.
Signal diagram reference: See Figures 2–8, 2–4, and 6–2 for wiring
diagrams.
Action: Do the following:
1. Make sure the top cover is installed correctly, as shown in Section 9.20.
2. Open and inspect the top cover and tang. If you see any broken or damaged
plastic, replace the top cover.
3. Use a small screwdriver to manually depress the spring linkage.
•
If the printer rollers start, inspect the top door, top door, and spring
linkage.
•
If the linkage is firmly stuck, inspect the switch and black plastic
stud.
4. Inspect the cabling and connectors that run between J201 on the DC
control board and J601 on the feed unit controller. Make sure both
connectors are securely plugged in and the cable is in good condition.

the DEClaser 5100 printer:
Table 7–1 Types of jams
Terms
Definition
Feed Failure
Paper never left the input device or never fed into the paper path.
Shingle jams
Leading edge of the bottom sheet slides under the tailing edge of the
front sheet. The pattern resembles roofing shingles.
Stalled paper
Paper stops in the paper path. The removed sheet is undamaged.
Phantom jams
A "Paper Jam" message that occurs for no foreseeable reason. The
message can occur spontaneously, intermittently, or continuously.
Phantom jams might occur without any paper feeds. These jams are
commonly caused by a bad sensor, cabling, or control board.
Wrinkled,
Skewed,
Notched,
Dog-eared,
or Shredded
Paper damage caused by a serious paper path malfunction. A
common cause might be obstructions, broken paper path guides,
rollers, or roller pressure springs.
7.2 Identifying the Location of the Jam
This section describes how to indentify where the the jam has occured.
Before you fix a jam, Before you try to fix a paper jam, you must:
1. Print enough copies of the test page to determine the location, frequency,
repeatability, and the type of jam.
2. Using this information, along with Figure 7–1, determine the type and
location of the jam.
3. See Table 7–2 to determine which jam FIP to turn to.

The MODE= Centronics value configures the port to operate as a standard,
unidirectional Centronics printer. Centronics is the most commonly
selected value.
•
The Mode= 2-way 1284 value configures the port to conform to the Institute
of Electrical and Electronic Engineering (IEEE) 1284 standard. The IEEE
1284 standard extends the existing personal computer parallel interface by
adding bi-directional characteristics.
The value you select must match the description of the host system’s parallel

changes by ±1 when you press < or > and by ±10 as you hold down the key.
PCL: Orientation
The ORIEN= landscape or ORIEN= portrait values set the orientation of the
image on the sheet.
PCL: Page protect
The PROTECT= off, PROTECT= Ltr/A4, and PROTECT= Legal values reserve
bitmap memory for full page bitmapping. The page protect operation competes
for memory with font storage, jam recovery, and high resolution values that
significantly slow down the printer, depending on the complexity of the
printing image. For additional information about the page protect feature see
the DEClaser 5100 Printer User’s Guide.
PCL: Pitch
The value you select establishes the character spacing of the selected
monospaced typeface. When selected, the PITCH= 10.00 prompt appears.
The character spacing number spans from 00.44 to 99.99 characters per inch
(CPI). The default is 10.00. The value changes by ±00.01 when you press <
or > and by ±1.00 as you hold down the key.
PCL: Point size
The value you select sets the size of the proportional typeface selected by the
font source and number values. When selected, the PCL: Point size= 12.00
prompt appears. Point sizes vary from 4.0 to 999.75. The default point size is
12.0. The value changes by ±0.25 when you press < or > and changes by
±1.0 as you hold down the key.
PCL: Resolution
For the values associated with this prompt, see the PS: Resolution entry.
PCL: Symbol set
The value you select determines the PCL default symbol set and displays the
SET= Value prompt. The term ‘‘symbol set’’ is also known as a ‘‘character set.’’

The MS–DOS and Windows PC operating system use the parallel and serial
ports to communicate with the printer. The parallel port is the system’s
default. The serial port is used when the parallel port is occupied.
•
Use the parallel port if the printer is less than 3 meters (10 feet) from your
computer.
The parallel port supports IEEE 1284 bidirectional and Centronics
unidirectional communications.
•
•
The DEClaser 5100 printer serial port supports both the EIA-232 and
EIA-422 communication protocols. EIA-323 is universally accepted while
EIA-422 is available on most systems.
–
Choose EIA-232 for distances up to 15 meters (50 feet) and baud rates
up to 19200. Use lower speeds for longer distances.
–
Choose EIA-422 for high baud rates and long distances.
The default serial communications settings are:
