1.3 Cautions on Service Operations

1) Be sure to remove the power cord unless otherwise required.

While the printer is powered ON, never touch the conductive parts unless
otherwise required.
Never touch the conductive parts of the power switch and inlet of the LVPS,
because they are live even while the printer is powered off.

2) When checking some parts with covers removed and with the interlock, safety, and power switches
ON, disconnect the connectors (P/J411 and P/J412) on the ROS ASSY except unless otherwise
required.

When checking some parts with covers removed and with the interlock, safety, and
power switches ON, laser beams may be irradiated from the ROS ASSY. For your
safety, be sure to disconnect the connec tors (P/J411 and P/J 412 ) unless otherwise
required.

3) When checking some parts with the Front Cover removed and the printer powered ON, be sure to
remove the connector (P/J16) on the PWBA MCU unless otherwise required.

When checking some parts with the Front Cover removed and the printer powered
ON, be sure to remove the connector (P/J16 ) on the MCU. Otherwise, a high voltage
may be output from the HVPS.
When connecting the connector (P/J16) on the MCU according to the instructions
in the FIP, never touch the HVPS and high voltage parts.

Revision B

4) When outputting a high voltage using the Diag Tool, etc., keep all the covers on unless otherwise
required.

When outputting a high voltage using the Diag Tool, etc., ensure that:

- The high voltage carrying parts must never be touched.

- The instructions in this manual must be followed.

5) When operating the drive unit using the Diag Tool, etc., keep all the covers on unless otherwise
required.

When operating the drive unit using the Diag Tool, etc., ensure that:

- The drive unit must never be touched.

- The instructions in this manual must be followed.

6) When touching hot parts, be careful not to get burnt.

7) While working, be sure to wear a wrist band or the like to dissipate static charges from your body.

Chapter 1 Troubleshooting

1.4 Cautions on Using FIP

1) When troubleshooting according to the FIP, have on hand a normal MCU, LVPS, HVPS, Fuser
Unit, TRANSFER ASSY, etc., for possible fault isolation.

2) In the initial check according to the FIP, check only items which can be simply checked.

3) In the initial check according to the FIP, check the constitutive parts of the major check parts and
related parts, as well as major check parts.

4) When working with the printer, be sure to remove the power cord unless otherwise required. Never
touch live parts if not required, while the power cord is connected.

5) Connector condition is denoted as follows:
[P/J12]
[P12]

[J12]

 Connector (P/J12) is connected.
 Plug side with the connector (P/J12) removed (except when attached directly to the

board).

 Jack side with the connector (P/J12) removed (except when attached directly to the

board).

Revision B

6) [P/J1-2PIN <=> P/J3-4PIN] in the FIP means measurement with the positive side of the measuri ng
instrument connected to [2PIN] of [P/J1] and the negative side to [4PIN] of [P/J3].

7) [P/J1<=> P/J2] in the FIP means measurement for all terminals corr espondin g between [P/J1] and
[P/J2] based on “Wiring Diagrams”.

8) In [P/J1-2PIN <=> P/J3-4PIN] in the FIP where voltage is measured, [P/J3-4PIN] on the rear
negative side is always at the AG (analog ground), SG (signal ground), or RTN (return).
Therefore, after checking of proper conductivity between AGs, SGs, or RTNs respectively, the rear
negative side can be connected to the PIN of AG, SG or RTN instead of [P/J3-4PIN].
However, care should be taken not to confuse [AG], [SG], and [RTN] because they are not on the
same level.

9) When measuring the voltage at small connectors, use the dedicate d tool. Handle the tool with ca re
because its business end is pointed.

10) When measuring the voltage, set the TRANSFER ASSY, toner cartridge and sheet feeder, close
the COVERs and power ON unless otherwise required .

11) Numerical values in the FIP are only for guideline. Approximate values are acceptable.

12) In each step of the FIP, parts removal and other procedures implicitly required for the ste p are
omitted.

13) In the FIP, "Replacement" means the replacement of the parts that are consider ed to be the cause
of the trouble. Replacement of those parts means the replacement of the assembly part (HIGH
ASSY) that contain them.

14) In the FIP, the sheet feeder immediately below the printer main body is called "Tray 1", and the
cassette below it is called "Tray 2".

15) Some of the instructions in the FIP are branched off depending on the specifications. Follow the
applicable instruction.

16) For some optional components, you may have to refer to the manual of the relevant compo nent for
troubleshooting. Have the relevant manual at hand as needed.

Print Media Guidelines

Print media refers to paper, labels, envelopes, and coated paper among others. Your printer provides
high-quality printing on a variety of print media. Selecting the appropriate print media for your printer
helps avoid printing troubles. This section describes selecting print media, caring for print media, and
loading the print media in the standard 250-sheet tray.

Paper

For the best print quality in color, use 75 g/m
quality in black and white, use 90 g/m

you perform trial print before purchasing large quantities of print media.
When loading paper, identify the recommended print side on the paper package, and load the paper
accordingly. See "Loading Print Media in the Standard 250-Sheet Tray and the Optional 2 50-Sheet
Feeder" and "Loading Print Media in the SSI" for detailed loading instructions.

Paper Characteristics

The following paper characteristics affect print quality and reliability. It is recommended that you follow
these guidelines when evaluating new paper stock.

2

to 216 g/m2 (16 lb to 80 lb

Curl

Curl is the tendency of print media to curve at its edges. Excessive curl can cause pape r feeding prob­lems. Curl usually occurs after the paper passes through the printer, where it is exposed to high tem­peratures. Storing paper unwrapped, even in the paper tray, can contribute to paper curling prior to
printing and cause feeding problems regardless of humidity. When printing on curled paper, straighten
the paper and then insert it into the single sheet feeder.

Smoothness

The degree of paper smoothness directly affects the print quality. If the paper is too rough, the toner
does not fuse on to the paper properly, resulting in poor print quality. If the paper is too smooth, it can
cause paper feeding problems. Smoothness between 150 and 250 Sheffield points produces the best
print quality.

Moisture Content

The amount of moisture in the paper affects both the print quality and the ability of the printer to feed
the paper properly. Leave the paper in its original packaging until you are ready to use it. T his limits the
exposure of the paper to moisture changes that can degrade its performance.

Grain Direction

Grain refers to the alignment of the paper fibers in a sheet of paper. Grain is either grain long, running
the length of the paper, or grain short, running the width of the paper. For 60 g/m
36 lb bond) paper, grain long fibers are recommended. For paper heavier than 135 g/m

2

to 135 g/m2 (16 lb to

2

(36 lb bond),

grain short is preferred.

Fiber Content

Most high-quality xerographic paper is made from 100% chemically pulped wood. Paper containing
fibers such as cotton may lead to degraded paper handling.

Revision B

Recommended Paper

To ensure the best print quality and feed reliability, use 75 g/m

2

(20 lb) xerographic paper. Business
paper designed for general business use also provides acceptable pri nt quality. Only use paper able to
withstand high temperatures without discoloring, bleeding, or releasing hazardous emissions. The laser
printing process heats paper to high temperatures. Check with the manufacturer or vendor to dete rmine
whether the paper you have chosen is acceptable for laser printers.
It is recommended that you perform trial print before purchasing large quantities of print media. When
choosing any print media, you should consider the weight, fiber content, and color.

Unacceptable Paper

The following paper types are not recommended for use with the printer :

• Chemically treated paper used to make copies without carbon paper, also known as carbonless

paper, carbonless copy paper (CCP), or no carbon required (NCR) paper.

• Preprinted paper with chemicals that may contaminate the printer.

• Preprinted paper that can be affected by the temperature in the fuser unit.

• Preprinted paper that requires a registration (the precise print location on the page) greater than

±0.09 inches, such as optical character recognition (O CR) form s.

Epson AcuLaser C2900N

1 - 8

Confidential

Chapter 1 Troubleshooting

In some cases, you can adjust registration with your software program to successfully print on these
forms.

• Coated paper (erasable bond), synthetic paper, and thermal paper.

• Rough-edged, rough or heavily textured surface paper, or curled paper.

• Recycled paper containing more than 25% post-consumer waste that does not meet DIN 19 309.

• Multiple-part forms or documents.

• Print quality may deteriorate (blank spaces or blotches may appear in the text) when printing on talc

or acid paper.

Selecting Paper

Proper paper selection helps prevent jams an d en su re s tro u ble-free printing.
To help avoid jams or poor print quality:

• Always use new, undam a ge d pa p er .

• Before loading the paper, identify the recommended print side of the paper.

This information is usually indicated on the paper package.

• Do not use paper that you have cut or trimmed.

• Do not mix print media sizes, weights, or types in the same source. This may result in a paper jam.

• Do not remove the tray while printing is in progress.

• Ensure that the paper is properly loaded in the tray.

• Flex the paper back and forth, and then fan them. Straighten the edges of the stack on a level sur-

face.
