1.3.2 Paper Path Jam Detection Circuits

The paper path sensors monitor the progress of a sheet of paper through
the duplex paper path. The sensors are actuated by linkages that protrude
into the paper path and are deflected by the forward-moving paper.

Figure 1–9 shows the location of!the fixing unit exit,"inverter, and

#

second pass sensors. It also shows the duplex paper path, the rollers, and
the facedown fork gate.

MLO-004931

The dc control board monitors the sensors during power-up and at specific
times during the print cycle. During power-up the fixing unit exit and
second pass sensors are checked. If either sensor detects paper, the printer
does not warm up, display READY, or go on line. The printer can be
powered up and display READY with paper in the paper path, but not
if the paper is under either sensor.

1–14 DEClaser 2200 Printer Service Guide

During the print cycle, the dc control board compares the timing and sensor
events to track the paper as it travels through the paper path. The print
cycle is initiated when a sheet of paper is fed into the paper path; the
cycle ends at the selected output stack. If the leading or trailing edge of
the paper fails to actuate a sensor within the expected time period, the dc
control board lights the control panel jam indicators, shuts down the fixing
unit heater, and causes the control panel beeper to sound.

The three jam indicators show the most probable location of a paper jam.
One sheet of paper can cause one, two, or all three indicators to light.
Figure 2–1 shows the three control panel jam indicators.

1.4.1 I/O Board

The I/O board can connect to a host system by a serial RS232C interface or
by a parallel 8-bit Centronics interface. Data passes directly through the
I/O board. See Section A.3 for pin-out and connector information.

NOTE: The switchpack mounted on some I/O boards is not used in the field.
The correct operational setting for both switches is open.

1.4.2 Video Control Board

The video control board receives commands and image data from the host
system through theI/Oboard. The image data is compiled into adotpattern
and stored in the page memory to be output to the laser scanner assembly
through the dc control board.

Figure 1–11 shows the major blocks of the video control board.

• The main central processing unit (M–CPU) is a 32-bit microprocessor
that controls all activity on the video control board.

• The subcentral processing unit (S–CPU) is a 16-bit microprocessor that
operates as a slave to the M–CPU.

DEClaser 2200 Physical and Functional Description 1–17

The S–CPU does the following.
– Controls the host system and video control board communication,

through the logic on the I/O board.

– Reads and operates the keys, display, and all indicators on the

control panel except the jam indicators. (The jam indicators are
operated by the dc control board.)

– Controls read/write access to theelectricallyerasableprogrammable

read-only memory (EEPROM). The EEPROM is referred to as
NVRAM by the control panel display (nonvolatile random-access
memory).

– Operates the dc control board through 14 logic level signals shown

in Figure 1–12 and Figure 1–14.

– Generates refresh clock pulses that maintain data bits stored in

dynamic random-access memory (DRAM).

– Controls all communication between the M–CPU and elements on

the video control board.

• Gate array 1 (GA1) controls the direct memory access (DMA) process
to the DRAM. The DRAM is accessed by the dc control board and by
devices on the video control boards.

• Gate array 2 (GA2) controls the transfer timing of the dot pattern data
to the dc control board.

• The DRAM is divided into the following three fields (the size of which
is adjustable through the control panel setup menu):

– The page or input buffer contains data received from the host

system.

– The page memory contains the image data bitmap or dot pattern

data.

– The font cache memory contains processed fonts.

• The read-only memory (ROM) holds the image data that makes up the
internal fonts and stores the firmware operating programs of the video
control board.

1–18 DEClaser 2200 Printer Service Guide

1.4.3 DC Control Board Signals

The dc control board operates and distributes power to all the electronic and
electromechanical components in the duplex unit and print engine. With
the exception of the scanner assembly, all connections to the dc control
board are made by the following three connectors:

• J214 is a 40-pin connector that carries all print engine connections.

• J215 is a 40-pin connector that carries all duplex and inverter unit
connections.

• J216 is a 9-pin, high current type connector that connects dc power to
the dc control board.

Figure 1–12 and Figure 1–13 show the input signals to the dc control board
from the print engine, duplex unit, and video control board.

The fixing heater current is controlled by ac driver and safety circuits,
whereas the fixing temperature is measured and regulated by the dc control
board. The ac driver and safety circuit are parts of the ac inlet assembly
field replaceable unit (FRU). Figure 1–17 is a diagram of the circuits that
control the fixing unit heater.

MLO-004917

The ac line power is directed through the power switch, noise filter, and
CB101. From CB101 the ac line power is directed to the LVPSA and to the
fixing heater circuits.

The following serial devices control the fixing heater current:

• Relay RL01 is operated by the safety circuit.

• The solid state relay (SSR) is operated by the dc control board.

• The thermoprotection (TP1) switch is actuated directly by the heat
coming off the fixing heat roller.

DEClaser 2200 Physical and Functional Description 1–25

Safety Circuit

The safety circuit consists of a fixing heater current monitor and a timer
circuit that controls relay RL01. The current transformer monitors the
current drawn by the fixing heater and charges C153. If the fixing current
get too high, C153 turns on Q153, which opens the RL01 contact. The

FSRD

signal also causes C153 to fully charge when a fixing unit error (50

SERVICE) has occurred.
Once RL01 has opened, it is kept open until C153 discharges. C153 stays

fully charged until the ac power is turned off, then C153 slowly discharges.
About 10 minutes are required for the discharge. If you turn the power back
on before C153 discharges, C153 recharges and the 50 SERVICE message
is redisplayed.

SSR Circuit

The SSR switches the fixing heater current on and off to regulate the fixing
unit temperature. The resistance of the thermistor (TH1) varies according
to the heat of the fixing roller. The dc control board measures the resistance
of TH1 and turns SSR on to raise the temperature or off to allow the fixing
unit to cool.

• When the printer is at standby, the fixing temperature is maintained
at 165°C (329°F).

• When the printer starts to print, the fixing temperature is quickly
raised to 180°C (356°F).

The dc control board displays the 50 SERVICE error message if the fixing
unit roller temperature:

• Fails to exceed 30°C (86°F) within 18 seconds after power on

• Fails to exceed 165°C (329°F) within 90 seconds after power on

• Exceeds 230°C (446°F)

• Drops below 140°C (284°F) after the Ready indicator goes on

1–26 DEClaser 2200 Printer Service Guide

SW205

Switch SW205 is mechanically actuated by the bottom cover. When the
bottom cover is on, the switch is open and TH1 operates normally. When
the cover is off, the SW205 is closed and a dummy load is connected
across TH1, thus simulating a correctly warmed fixing temperature. The
dc control board never turns on the SSR, and the fixing unit stays cool.
SW205 is not used in the field. The TP1 thermoprotection switch is a
passive temperature-operated switch that is mounted next to the fixing
heater roller. TP1 opens if the fixing unit temperature climbs to 210°C
±10% (410°F).

1.4.6 HVPSA Circuits

The HVPSA assembly consists of the high-voltage power supplies and an
attached connector block that are crucial to the production of the image.
The assembly is replaced as an FRU. You should not attempt to adjust the
HVPSA in the field.

When the top cover is closed, the EP-S cartridge contacts make connection
with the coil and flat spring contacts of the connector block. The coil
spring contacts are used for high-voltage connection. The flat spring
contacts connect the toner sensor signal and high-voltage common return
bus (HVGND) to the EP-S cartridge.

The coil spring connectors are chrome plated and require no maintenance.
Use a soft brush to clean away dust or paper chips, but avoid using
commercially available liquid or aerosol contact cleaners. Replace the
HVPSA if the connector block plastic is broken or damaged, or if the
contacts appear burnt, pitted, or bent. Do not attempt to scrape clean,
bend back, or repair damaged contacts.

The amount of available memory deter­mines which values are displayed.

• If the minimum amount of memory
is installed (1024 KB), you can only
select the Partial value; Full and
Dual are not displayed.

• If the 1-MB optional memory is
installed, you can select Partial or
Full; Dual is not displayed.

• If either the 2-MB or 3-MB optional
memory or more is installed, you can
select Partial, Full, or Dual.

The paint selection allocates the size of
the font cache and page areas of available
memory. As more and more processed
(bitmapped) fonts are cached, more of the
available memory is utilized; this leaves
less room for bitmapped print data and
slows down the printer. More time is
required to bitmap a smaller area, which
eventually causes the 21 COMPLEX
DATA message to be displayed. See
Table 3–3 for additional information.

• When you select Partial, a portion of
a page is bitmapped, then printed.

• When you select Full, one full page is
bitmapped, then printed.

• When you select Dual, two complete
single-page bitmaps are reserved in
memory. This enables the printer to
simultaneously print page one and
bitmap page two.

The selected value of the paper feature
establishes the default size of the image
and the sheet of paper that are requested
for manual feeding.

The printer adjusts the size of the image
to fit on the requested size sheet and
displays the paper feed message to prompt
an operator to load a specific size sheet of
paper. See the PF FEED messages listed
in Table 3–2 for details of the paper feed
message.

The following actions establish the size of
the printed image and the requested sheet
size:

1. Escape sequences transmitted from
the attached host system select any
of the standard sizes or can set a
variable size.

2. If no escape sequences are received
(for example, when you print the test
patterns in offline ready mode), the
cassette size key selects the image
and paper size to the size of the
installed and selected cassette.

3. If no escape sequences are received
and no cassette is installed, the
selected paper value determines the
image size and the paper feed size.

The LOAD<– ROM factory values are in bold.
The equal (=) sign indicates the selected value. When you scroll into a value level, the selected

value is displayed first.

3.4 Troubleshooting Paper Jam and Feed Faults

This section is the fault isolation procedure (FIP) for correcting paper jam
problems in the DEClaser 2200 printer.

Refer to Section 1.3.2 for information about the rollers, sensors, and the
shape of the paper path.

3.4.1 Jam Troubleshooting Start FIP

FIP NOTES: This section of the FIP is used to repair a printer that jams

or displays jam symptoms. Start your troubleshooting at Figure 3–3, which
will direct you to one of the following specific subsections:

• Section 3.4.1 for jam indications that occur at power-up or occur
spontaneously. These indications are sometimes called phantom jams
because there is no sheet of paper in the paper path.

• Sections 3.4.2–3.4.6 for jams that occur in areas 1–4 that are inside the
printer. Figure 3–4 shows the location and boundaries of the four areas.
