type) and toothed washer are used in the correct places.
Never create a closed circuit across connector pins except those
specified in the text and on the printed circuit.
When creating a closed circuit and measuring a voltage across
connector pins specified in the text, be sure to use the GND wire.
HANDLING OF PWBS
During Transportation/Storage:
During transportation or when in storage, new P.W. Boards must
not be indiscriminately removed from their protective conductive
bags.
Do not store or place P.W. Boards in a location exposed to
direct sunlight and high temperature.
When it becomes absolutely necessary to remove a Board from
its conductive bag or case, always place it on its conductive mat
in an area as free as possible from static electricity.
Do not touch the pins of the ICs with your bare hands.
Protect the PWBs from any external force so that they are not
bent or damaged.
During Inspection/Replacement:
If it becomes necessary to replace the thermal fuse or any other
fuse mounted on a board, be sure to use one of the rating marked
on the blown fuse. Always note the rating marked on the fuse, as
the rating and mounting site or number used are subject to change
without notice.
Avoid checking the IC directly with a multimeter; use connectors
on the Board.
Never create a closed circuit across IC pins with a metal tool.
Before unplugging connectors from the P.W. Boards, make sure
that the power cord has been unplugged from the outlet.
When removing a Board from its conductive bag or conductive
case, do not touch the pins of the ICs or the printed pattern.
Place it in position by holding only the edges of the Board.
When touching the PWB, wear a wrist strap and connect its cord
to a securely grounded place whenever possible. If you cannot
wear a wrist strap, touch a metal part to discharge static
electricity before touching the PWB.
HANDLING OF THE PC DRUM
* Only for Products Not Employing an Imaging Cartridge.
During Transportation/Storage:
Use the specified carton whenever moving or storing the PC
Drum.
Note that replacement of a PWB may call for readjustments or
resetting of particular items.
HANDLING OF OTHER PARTS
The magnet roller generates a strong magnetic field. Do not bring it
near a watch, floppy disk, magnetic card, or CRT tube.
The storage temperature is in the range between -20°C and
+40°C.
In summer, avoid leaving the PC Drum in a car for a long time.
Handling:
Ensure that the correct PC Drum is used.
Whenever the PC Drum has been removed from the copier,
store it in its carton or protect it with a Drum Cloth.
The PC Drum exhibits greatest light fatigue after being exposed
to strong light over an extended period of time. Never, therefore,
expose it to direct sunlight.
Use care not to contaminate the surface of the PC Drum with oil-
base solvent, fingerprints, and other foreign matter.
Do not scratch the surface of the PC Drum.
Do not apply chemicals to the surface of the PC Drum.
Do not attempt to wipe clean the surface of the PC Drum.
If, however, the surface is contaminated with fingerprints, clean it using
the following procedure.
1. Place the PC Drum into one half of its carton.
3. Soak a small amount of either ethyl alcohol
or isopropyl alcohol into a clean, unused
Dust-Free Cotton Pad which has been
folded over into quarters. Now, wipe the
surface of the PC Drum in one continuous
movement from its rear edge to its front
edge and off its surface one to two times.
2. Gently wipe the residual toner off the
surface of the PC Drum with a dry, DustFree Cotton Pad.
A.Turn the PC Drum so that the area of its
surface on which the line of toner left by the
Cleaning Blade is present is facing straight
up. Wipe the surface in one continuous
movement from the rear edge of the PC
Drum to the front edge and off the surface
of the PC Drum.
B. Turn the PC Drum slightly and wipe the
newly exposed surface area with a CLEAN
face of the Dust-Free Cotton Pad. Repeat
this procedure until the entire surface of the
PC Drum has been thoroughly cleaned.
*At this time, always use a CLEAN face of the dry
Dust-Free Cotton Pad until no toner is evident on
the face of the Pad after wiping.
*Never move the Pad back and forth.
4. Using the SAME face of the Pad, repeat the
procedure explained in the latter half of
step 3 until the entire surface of the PC
Drum has been wiped. Always OVERLAP
the areas when wiping. Two complete turns
of the PC Drum would be appropriate for
cleaning.
NOTE:
Even when the PC Drum is only locally dirtied, wipe the entire
surface.
Do not expose the PC Drum to direct sunlight. Clean it as
quickly as possible even under interior illumination.
If dirt remains after cleaning, repeat the entire procedure from
the beginning one more time.
HANDLING OF THE IMAGING CARTRIDGE
* Only for Products Employing an Imaging Cartridge.
During Transportation/Storage:
The storage temperature is in the range between -20°C and
+40°C.
In summer, avoid leaving the Imaging Cartridge in a car for a

1.4.5 Printer Setting Items (Only with AcuLaser C900)
This section describes setting items for AcuLaser C900.
For setting of the items described below, use the “Printer Setting” dialog box on the
“Optional Settings” of the printer driver.
Since there are no character strings administrated by the printer, the names of setting
items and setting values referred to below are only for explanation. Therefore, these
names may not match the character strings displayed in driver's user interfaces or the
status sheet.
1.4.5.1 Setting Items stored on the Printer Side
Values shown in bold and underlined characters are the factory default setting values.

Paper Source Priority
Set a priority order when Auto Selection is selected by the paper source setting and
the paper sources matches the designated paper size.
This is the same function as the “MP Mode” function of ESC/Page models.
MP Tray : MP tray > Cassette
LC : Cassette > MP tray
LC only : Cassette
However, to continue printing when the paper sources has no paper which matches the
target paper size, papers are fed from the paper sources in the order of MP tray >
cassette.
The default setting differs depending on the destinations: “MP tray” for worldwide
models.
NOTE: The printer can set “LC only”, but the driver cannot select it since the
same function is can be achieved by selecting a cassette from the paper
source.
MP Tray Size
Assign a paper size for the MP tray. If the printing is continued after the “Paper
Set” error occurrence and the paper size designated by the printing data matches
the paper size which is actually fed, the paper size will be stored in memory. The
default value is either “A4” or “LT” depending on the jumper setting (R190/
INPT0) on the controller board.
NOTE: The paper sizes which can be handled by the MP Tray Size function of
AcuLaser C900 driver is limited to:
A4, A5, B5, LT, HLT, GLT, EXE, MON, C10, DL, C5, C6, IB5
LC Size
Specify a paper size for the optional cassette size. The default value is not affected
by the controller configurations and is always set to “A4”.
Toner Out Error

Paper Source
Paper feeders are selected by the paper source setting.
Actually, however, paper feeders are selected in the following priority order, since
the paper type and the paper size settings influence the selection of paper feeders.
Paper Type = Thick paper, Transparency, Coated paper, or Envelope:
The MP tray is selected
Paper Type = Normal, and Paper Size = postcards or envelope:
The MP tray is selected
Paper Type = Normal, and Paper Size ≠ postcards or envelope
• Paper Source =MP Tray or LC:
The designated paper feeders are selected.
• Paper Source=AUTO, when the feeders which match up to the designated
paper sizes are available:
According to the priority order, paper feeders are selected.
• Paper Source=AUTO, when the feeders which match up to the designated
paper sizes are not available:
According to the priority order, paper feeders are selected among the feeders
which have papers.
NOTE: By the driver, when Paper Type ≠ Normal or Paper Size = F4 or
envelope, the MP tray can be selected.
Users can select setting values above with the driver, and the printer operates according
to the selected setting values.
Paper Size
A paper size for printing is selected by the paper size setting.
Like the MP tray Size, paper size permits the setting of paper sizes supported by
the driver.
Undefined means the paper width is 92 to 216 mm and the paper length is 148 to
297 mm. However, for sheets of paper with a length not shorter than 148 mm but
shorter than 210 mm, printing is carried out in the low-speed <2> mode.
Copies
The number of multi-copies is designated by the copies setting.
Resolution
A resolution for internal processing is selected by the resolution setting.
Product Description Control Panel 60
EPSON AcuLaser C1900/AcuLaser C900 Revision A
Duplex Printing
Select Simplex printing or Duplex printing.
Permit Duplex printing only when the paper size is A4 or LT. With any other
paper size, the selection of Duplex printing is invalid, displaying the error message
“Can't print duplex”.
NOTE: The driver also provides the ability to cancel Duplex printing in the
paper size and paper type settings.
RITech
The RITech function can be enabled or disabled in the RITech setting.
Toner Save
Select whether the Toner Save function is enabled or disabled.
Top Offset
Set the print starting vertical position on a sheet.

1-millimeter increments.
Binding margins for Duplex printing with the Top Offset setting value are
limited to 0 ~ 30 mm in 1-millimeter increments.
Page Side
In the manual duplex printing mode, this setting determines whether to use the side
of a sheet being printed first (Front) or the opposite side to the already printed side
(Back).
NOTE: The user must be advised to select the paper side in combination with
paper types. This setting is required at printing on thick paper, coated
paper or postcards. For printing on a postcard (back side), set
“postcard” or “double postcard” as the paper size, “plain paper” as the
paper type and “back” as the paper side.
Size Ignore
Select whether or not to ignore the errors “Paper Set” and “Check Paper Size”.
Avoid Error
Select whether or not to avoid occurrence of any of the followings: “Paper Set”,
“Invalid Size”, “Mem Overflow”, “Duplex Mem Overflow”
ON: The printer continues printing without displaying any of the above
errors. “Paper Set” does not occur, but “Check Paper Size” appears if
the paper size of the fed sheet is not as designated. None of “Invalid
Size”, “Mem Overflow”, and “Duplex Mem Overflow” occurs, but
“Print Failure” appears.
Left Offset
Set the print starting horizontal position on a sheet.
NOTE: The printer permits the setting in the range of about - 30.0 ~ 30.0 mm in
1-dot increments, while the setting by the driver is limited to - 9 ~ 9 mm in
1-millimeter increments.
Binding margins for Duplex printing with the Top Offset setting value are
limited to 0 ~ 30 mm in 1-millimeter increments.

Usually, the transfer voltage is automatically adjusted. However,
you are advised to use the transfer voltage offset setting function
when automatic adjustment does not compensate adequately
(satisfactory image quality is not obtained), especially, when
special paper is used. With the same paper type for which the
setting has been changed, the image quality may be affected
depending on the specifications for the paper which is actually
used. Take due care.

1.6 Handling Precautions
1.6.1 Caution when there is a Power Failure
AcuLaser C1900 / AcuLaser C900 is equipped internally with nonvolatile memory
(E2PROM). This nonvolatile memory preserves the settings for printer functions, and
if the power is cut during writing to the nonvolatile memory, the contents of the
nonvolatile memory can not be guaranteed, with the result that when the power is
turned on again, or when Reset All is executed, the panel setting values will return to
the default settings, or a Service call error will occur.
With AcuLaser C1900, HDD can also be connected to this printer, but if the power is
cut during writing to the HDD, the writing contents can not be guaranteed, so a HDD
error may occur. Accordingly, in the following cases, the power to AcuLaser C1900
should not be cut while writing to the nonvolatile memory or to the HDD.
From the time the power is turned on until the On Line LED lights up
continuously.
While the Ready LED is blinking.
While the printer is printing (while the paper feed motor is operating).
While the Data LED lights up, or when it is blinking.
1.6.2 Caution Regarding High Temperature Parts
Take care not to touch the Fuser unit while the printer, is being opened to remove a
paper jam, etc., since the temperature of the Fuser unit inside the printer becomes high.

with AcuLaser C900 via these protocols. The network setup section in AcuLaser C900
manual describes that users or administrators should set NetBEUI and Netware
protocol to DISABLE.
4: FTP, IPP and NDPS Gateway protocols can not be set to DISABLE and users can send
data to AcuLaser C900 via these protocols. But the Status Monitor can not
communicate with the printer via these protocols, so that protocols are out of

1.11.2 Differences between AcuLaser C900 and AcuLaser C1000
AcuLaser C900 is different from AcuLaser C1000 in the following points:
Usability
The both-way postcard is added to the paper sizes supported (for domestic
models).
The toner cartridge must be replaced while the printer is powered on.
Specify the toner to replace from the driver, when replacing it before it
expires.
The standard paper feed device is just one tray, but you can add one more
optional cassette.
Service
The fuser oil roll is removed, and the service life of Photoconductor Unit and
Transfer Belt are extended.
Improving the AIDC control upgrades the picture stabilization.
Since Waste T Box is not set with Photoconductor Unit, the packing box
becomes compact.
The printing density level, second transfer voltage, and fuser temperature can
be adjusted.
The ESCPAGES-02 command can be used to print Engine Status Sheet.
The life of the Fuser Unit is elongated and also there is no worry about
breakage of belts. Therefore, the “printing impossible” error caused by
expiration of life does not occur and the “near end” warning is not given.
The toner supplied with the main unit has a shorter service life than the one
designated commercially as consumable.
Since Waste T Box is not set with Photoconductor Unit, the Waste T Box has
a shorter service life than Photoconductor Unit.
After Fuser Unit is replaced, the counter must be cleared using the exclusive
tool.

The organic photoconductor can deteriorate by sensitivity change
due to light fatigue if is exposed to light for an extended period of
time. To prevent such deterioration, when the OPC Drum has
been taken out of the printer body, cover it with a clean soft cloth
to protect it from exposure to light.
In handling the Photoconductor Unit, take great care that no dirt
adheres to the surface of the photoconductor.
Grounding of OPC drum
The grounding contact of the OPC drum is located in its rear inside and always in
contact with the shaft. When the Photoconductor Unit is installed in the printer
body, the shaft of the Photoconductor Unit comes in contact with the grounding
plate in the printer body to achieve grounding. Thus, the electric charge on the
OPC drum exposed to light is grounded through the Grounding Contact, the Shaft
and the Grounding Plate to the Frame.

2.4.2.2 Charging Process
Charging is carried out by the needle electrode scorotron charger.
The OPC drum is charged evenly by the corona discharge from the charger via the Grid
Mesh.
Ozone generation is suppressed thanks to corona discharge concentration on the side of grid
mesh by use of the needle electrode type charger.

2.4.3 Exposure Process
The laser beam from the print head creates an electrostatic latent image on the OPC drum
surface.
SUB SCANNING DIRECTION (VERTICAL SCANNING DIRECTION)
When the printer receives the PRINT signal, the polygon motor (M3) and the main motor
(M1) operate, and paper feeding is started.
Printing in the sub scanning direction is started when the belt location detection sensor is
turned on.
MAIN SCANNING DIRECTION (HORIZONTAL SCANNING DIRECTION)
Upon receiving the SOS sensor signal from the Laser Control Board, the printer starts
printing in the main scanning direction.
