If SC76 occurs, take the following action:

1. Install the machine on a stable and level surface.

2. Place the three wedges that have been packed together with the machine under each
of the three feet.

3. If SC76 still occurs, attach the spacer to the machine according to the following
procedure.

Procedure for attaching the spacer:

1. Remove the belt cartridge.

2. Measure the gap L between side plate and OPC belt as shown in diagram 1.

3. Do one of the following actions depending the length of gap L:

Gap L (mm) Required action

0 – 3 Attach one spacer to the bearing on side A as shown in diagrams 2

& 3.

3 – 7 No action necessary

7 - 10 Attach one spacer on the bearing on side B as shown in diagrams

2 & 3.

Note: Clean the area of the bearing where the spacer will be attached with a cloth.

4. Install the belt cartridge and the turn on the machine.

5. Measure gap L after the machine has finished warming up.

6. If gap L is 3 mm to 7 mm, this procedure is complete. If gap L is less than 3 mm or
more than 7 mm, repeat this procedure from step 3 (attach one more spacer).
Note: Do not attach more than 2 spacers.

Early problem with Ricoh NIBs when using IE 5.x

Technical Services Dept., GTS Division

When you browse the Pomelo and FresaWIN printers with Microsoft Internet
Explorer 5.x (IE 5.x), IE 5.x requires installing a Japanese font even if the HT ML
does not have a Japanese font.
i.e., if browsing http://

Maybe the message is different because of a minor variation in the IE version or
Windows OS. The above message appears when using IE 5.00.2920.0000 with
Windows 2000. In this case, IE requires a Japanese font every time.

IE 5.00.2314.10003 with Windows NT 4.0 is shown below. In this case, IE requires
a Japanese font once after browsing the Ricoh NIB (network interface board).

Note:

The NIB works properly by canceling messages stating that a Japanese font

is required.

Problem NIB version

Problem printers

Pomelo

The HTML in the older version Ricoh NIB has the following line:

<META HTTP-EQUIV="content-type" CONTENT="text/html;
CHARSET=x-sjis">

This line means that HTML declares this file’s code is Japanese. Therefore IE 5.x
requires installing a Japanese font even if all HTMLs do not have a Japanese font.

The problem Ricoh NIB versions are 3.8.7 or earlier. The latest Ricoh NIB does not

include the problem line. Th e lat est one has the foll owing line:

<META HTTP-EQUIV="content-type" CONTENT="text/html">

This problem only happens with Pomelo and FresaWIN. However, the latest
Pomelo and FresaWIN do not have the problem. It depends on the time when the
NIB was produced.

Other printers and MFPs, such as Stinger-C, Russian-C/P, and Win-A, do not have
this problem because these Ricoh NIB versions are 3.8.8 or later.

Countermeasure 1

First check the Ricoh NIB version by printing the configuration page (Menu button

<Menu> List Print à <List Print> Config. Page). The configuration page shows

à

the Network Version line as follows:

Network

Version ELAND98 3.7.5 (0003)- 3.60f9

This line shows NIB version is 3.7.5.
If the NIB version is 3.8.7 or earlier, please get the latest Ricoh NIB firmware and

install the new one in the NIB.

Countermeasure 2

Install a Japanese font in Windows. There are a few ways to install Japanese fonts.

1) If IE 5.x is pre-installed in Windows 2000, the Windows 2000 CD-ROM has
Japanese fonts. The customer should insert the CD-ROM and click the OK
button.

2) Use Windows update from the Start up Menu in Windows and install the
Japanese font.

The MCTL board firmware has been modified in order to minimize the following. In
addition, the development drive unit was modified to minimize item #3.

1. Insufficient transfer in a band near at leading edge equivalent to one turn of the
development roller.

2. Dark lines on the printout at intervals of one development roller rotation.

3. Jitter at about 50 mm from the leading edge

Solutions:

1. For both #1 and 2 above:
The firmware has been changed so that if a large amount of prints are made using
only one DTM, the machine will rotate the development rollers in the unused DTMs at
the end of the job.

2. For #3 above:
The development drive unit has been modified so that the DTM drive speed is reduced
to about half speed. Also, the MCTL board firmware was modified in order to
synchronize the color switching timing with this new drive speed.

Notes concerning firmware solutions:

Old development

This RTB explains the OPC modification related to SC76 (belt tracking) as well as some
notes for servicing in the field.

Modification:

The OPC has been modified from the serial number mentioned below, but not as a direct
countermeasure for SC76. The modification simply made the occurrence conditions of
SC76 more strict, allowing the machine to continue operating on some surfaces that are
not perfectly level. So although there is still a limit, the machine's tolerance of inclined
surfaces has increased.

Action in the field:

SC76 normally does not occur if the machine is installed using three wedges on a sturdy,
level surface. Therefore, if SC76 occurs, take the action described in RTB #RG033004
first. The spacer for this countermeasure has been registered as a service part
(#G0449000).

NOTE: This service part is actually one set of 200 spacers.

Production Units:

The OPCs have been modified from the following cut-in serial numbers:

G033-17: P0690800001
G033-27: P0690900001
OPCs: Lot # xxxxxD or later (the lot # is written on the side plate of the OPC cartridge.)

Wording corrections for the LCD and configuration page
The following two functions have been added to the IPDL-C
menu in SP mode. This is the same as the Fresa Win+.

• Minimum Line Width Adjustment

• Toner Usage Display

The default setting of IPDL-C timeout has been changed from
300 s to 999 s.

If there is no paper of the required size in Auto Paper Select
mode and the "If the required paper size is not available, printing
will not start" checkbox has not been checked in the printer
driver, the printer will feed from the tray specified as the default in
the System Menu, instead of from the Current Tray (previous
method).
