IMPORTANT SAFETY NOTICES
PHYSICAL INJURY PREVENTION
1. Before disassembling or assembling parts of the printer and peripherals,
make sure that the power cord is unplugged.
2. The wall outlet should be near the printer and easily accessible.
3. Note that some printer components are supplied with electrical voltage even
if the main switch is turned off.
4. If an adjustment or operation check must be made requiring the removal or
opening of the exterior covers while the main switch is on, keep hands away
from electrified or mechanically driven components.
5. The printer drives some of its components when it completes the warm-up
period. Keep hands away from mechanical and electrical components when
the printer starts operation.
6. The interior and metal parts for the fusing unit become extremely hot while
the printer is operating. Do NOT touch these components with bare hands.
HEALTH SAFETY CONDITIONS
1. Never operate the printer without ozone filters installed.
2. Always replace the ozone filters with the specified replacement at the
specified maintenance intervals.
3. Toner is non-toxic, but if it gets in your eyes by accident, it may cause
temporary eye discomfort. Remove it with eye drops or flush eyes with
water. If this is unsuccessful, get medical attention immediately.
SAFETY AND ECOLOGICAL NOTES FOR DISPOSAL
1. Do NOT incinerate toner cartridges, development toner magazine (DTM) or
used toner. Toner dust may ignite suddenly when exposed to an open flame.
2. Dispose of used toner bottle and photoconductor unit (PCU) in accordance
with local regulations. (These are non-toxic supplies.)
3. Dispose of replaced parts in accordance with local regulations.

2.3 PRINT DATA PROCESSING
2.3.1 GRADATION & PRINTABLE DATA
The image can be printed with 1 bit or 2 bits (Default) in 600 dpi. However, a page
cannot be printed and the job is automatically canceled if the memory for image
processing overflows while converting the image data to bitmap format. This may
happen depending on the mode selected or the image data size.
If the memory overflows, gradation settings in the driver require changing by
printing the error message.
The printable size (combination of resolution, gradation and page size) is as
follows:

IPDL-C (Intelligent Page Description Language for Color)
The image data received from an
application is separated into three
elements: text, graphics, and
images. Then, the data for each
element is converted to IPDL-C.
The data converted is not done for
the whole page at once. Each
band (area specified) is
independently processed (banding
processing) for the data
conversion as shown in the figure.
The IPDL-C conversion from each
element is stored in free memory
and converted to bitmap data.
Bitmap data is compressed and
stored into the band pool memory ,
DRAM.
After data processing is complete,
the controller sends the
decompressed data to the printer
engine and the engine starts
printing.

CMS (Color Management System)
CMY realizes to optimize the color print quality by the color profile based on the
characteristics of the printer.
In Rcioh-Script2, CMS functions like the IPDL-C; but RGB conversion is done in
the controller.
CMS is used whenever the color profile setting in the printer driver is set to any
value other than “Off”.
Color Correction by the Driver
The driver adjusts the following parameters in accordance with the driver settings
made by the users: Brightness, Contrast, Saturation, and Color Balance
The driver does not perform RGB to CMYK conversion.
BG/UCR (Black Generation/Under Color Removal)
The RGB data sent to the controller is converted to CMYK data. During CMYK
conversion, some CMY data is replaced with K data by the BG/UCR algorithm.
Gamma Correction
The gamma curve can be adjusted in SP mode. For the adjustment procedure, see
“Section 6:Replacement and Adjustments” in the Controller Service Manual for the
base model (G024).
For CMYK, the density can be adjusted every 15 points from 0 to 100% (0,15, 30,
etc.). The corrected gamma data is stored in NVRAM memory.
The controller performs the gamma correction, RGB/CMYK conversion and
dithering.

Dither Processing
The dither pattern is prepared for the photo, text, graphic and thin lines
independently for 1- and 2-bit modes. These dither patterns creates the illusion of
256 gradations for high quality prints.
The optimum dither pattern is automatically selected based on the Text,
Photographic, and Image elements on the pages.
Maximum Amount Toner Control
The maximum toner amount is controlled in order to prevent toner from being
scattered around texts or lines printed.
The maximum amount values are prepared independently for text and photo. They
can be adjusted by the SP mode
• Default: 300%
• Adjustable range: 100% to 400% (step: 10%)
4 Bit Expansion
When the controller sends the data to the printer engine, the co ntroller expands the
data to 4 bits to meet the image-processing algorithm of the printer engine. When
expanding 1/2 bit to 4 bit, add some of the same data to the original data as shown
in the figure. Even when the data is expanded, dithering remains the same.

S7. Toner Limiter
The maximum toner values can be adjusted from 100 to 400% for both Text and
Photo Modes. The default value for both is 300%.
If this value is set high, the printed image appears more true to the original data.
However, since a greater amount of toner is used, it is easy to scatter the toner
around lines and text areas. If the value is set low, the color balance of low-density
areas varies, however toner does not scatter as easily.
NOTE: The values for the maximum toner amount are fixed for the base model
(G024), but adjustable for the G047/48.
S8. Brand (Default Setting: RICOH.EXP)
Use this mode to specify the brand. The machine will then display the correct
model name on the LCD and in the configuration page header.
NOTE: This must be done before delivering the printer to the customer site.
S9. Meter Click
In this mode, the counting method can be selected depending on the type of
Service Contract.
When the mode is activated:
1. A new user mode, “Show Counter” displays the counter values.
2. The printer will stop printing when toner has run out. In addition, “Toner Empty”
disappears from the Maintenance menu.
3. The configuration sheet includes the value for the counting method selected in
Meter Click mode, not the total counter value. Both counter values are included
in the engine maintenance sheet.
4. After selecting meter clock mode, the counter value for the selected counting
method is automatically set to 0. However, it cannot be reset to 0 after the
machine begins counting.
5. All developments/prints are counted at paper exit.

6.3 SOFTWARE UPGRADE PROCEDURE
The controller, Ricoh-Script 2, and network interface boards have a flash ROM for
storing control software. This allows version upgrades using an IC card.
The engine firmware cannot be upgraded using this procedure. See the engine
service manual for details on how to upgrade the engine firmware.
NOTE: Before starting an upgrade procedure, make sure that the software in the
IC card is newer than the software in the controller, Ricoh-Script 2, or
network interface board.
To check, do one of the following:
• Print out a configuration page (user mode).
• Enter controller SP mode and execute “3. Summary” with the [Media]
key. The software version is shown on the operation panel LCD.
Follow the procedure shown below to upgrade the software:
1. Turn off the machine, and then unplug all cables from the parallel interface
boards and network interface board, if connected.
2. For the duplex model only: Open the vertical transport unit.
3. Remove the controller board cover.
4. Remove the controller board and then install the upgrade IC card in the card
slot.
5. Turn on the machine. The machine automatically copies the software from the
IC card to the appropriate IC (controller, Ricoh-Script 2, or network interface
board).

Replacement
CAUTION: Do NOT turn off the machine while the software is being updated.
Otherwise, the controller, NIB, or Ricoh-Script 2 module may be
damaged.

REPLACEMENT AND ADJUSTMENT 30 June 2000
For the controller or Ricoh-Script 2:
The LCD display on the operation panel changes as shown below as the
rewrite procedure proceeds. (‘MELT’ is displayed during the software upgrade
for Ricoh-Script 2 since it involves a decompression process.)
(MELT ->) ERASE -> WRITE -> VERIFY -> OK!!OK!!
The appearance of the message “OK!!OK!!” indicates that the controller has
received the data from the IC card. However, note that it takes about 30
seconds to rewrite the data in the controller or Ricoh-Script 2 after this message
is displayed.
The message NG!!NG!!” is displayed if an error occurs during the rewrite
process. If this condition occurs, reinstall the IC card and turn the power off and
on again.
For the network interface board:
The appearance of the message “DOWNLOAD OK.” indicates that the
controller has received the data from the IC card. However, note that it takes
about 30 seconds to rewrite the data in the network interface board after this
message is displayed.
DOWNLOAD -> ############ -> DOWNLOAD OK.
The message “DOWNLOAD NG.” is displayed if an error occurs during the
rewrite process. If this condition occurs, reinstall the IC card and turn the power
off and on again.
1. When the rewrite ends, turn off the main unit, and remove the IC card.
2. Close the controller board cover.
3. For the duplex model only: Close the vertical transport unit.
4. Turn the power on again and print the user mode configuration page.
5. Check the new software version listed on the configuration page and make
sure that it matches the version on the IC card.
