AR-C170M  PRINTER CONTROLLER SECTION  14 - 8

This connector is USB Type-B 4-pin connector.

OKI ML60852A is used as USB controller. The USB Controller
device is connected with the 32-bit I/O Bus of D8501A, and IOCS0
is used. Moreover, a DMA controller uses DMAC Ch.0 in D8501A.

Built-in 1284 controller in D8501A is used, and 1284 interfaces are
controlled. 

• Supports IEEE1284 Compatible mode, Nibble Mode, Forward/

Reverse ECP mode (without decompression)

• Internal 16 bytes transmit buffer and 16 bytes receive buffer

supports.

• 2 channel DMA support (32 bit packed)

• Transfer data amount has to be multiple of 4-bytes.

This connector is 36 pin Amphenol connector based on IEEE1284. 

Engine Interface is supported in PRTC (Alpha-5) board. There are
a power supply line, Video-related signals, Scanner-related sig-
nals, and signals of communication relation with engine in this
Engine Interface. Moreover, Video-related signals and communi-
cation-related signals are controlled by D8501A. Scanner-related
signals are controlled by SCNIF ASIC on the SCNIF board via PCI
I/F.

AR-C170M  PRINTER CONTROLLER SECTION  14 - 9

Basic setting modifies or cancels factory settings of various printer
functions according to the use conditions. 

This program is set when inhibiting print of the caution notice
page.

Used to inhibit printing of the test page.

When this is set, the printer test page (Test page print) cannot be
printed by the user setting.

This setting allows printing on A4 size paper when letter size is
requested but there is no letter size paper.

∗

Printing on letter size paper when there is no A4 size is not
allowed.

This program is used to delete all data manually from the hard
disk.

When the built-in memory is full of printer data, further printing
cannot be made. Therefore, the contents stored in the memory are
printed. This program sets the print conditions. Factory setting is
"1 set."

This program is used to set the default paper type for paper
loaded in the bypass tray in printer mode. "NONE" (a default paper
type is not selected), "PLAIN", "HEAVY PAPER", or ''TRANSPAR-
ENCY" can be selected. If "HEAVY PAPER" is selected, select
"HEAVY PAPER 1" or "HEAVY PAPER 2". If "TRANSPARENCY"
is selected, select "SPEED MODE" or "QUALITY MODE".

The factory default setting is "NONE".

The interface setting is used to set data monitoring and control of
data sent to the machine parallel port and network port.

Used to select the parallel port and the network port of the
machine. 

This program is used to set Enable/Disable of printing from the
parallel port.

This program is used to set Enable/Disable of printing from the
USB port.

This program is used to set Enable/Disable of printing from the
network port.

After completion of printing, the port is

time-out

When the time set with I/O time-out 
time (item below) is reached, the port 
is set to auto selection.

AR-C170M  PRINTER CONTROLLER SECTION  14 - 10

This program is used to interrupt connection of the port when print
data are not sent  for a certain time to the port which is in standby
for print data reception, and used to set auto selection of port or to
start the next print data in standby for printing.

I/O time-out item means the time interval between print data
reception standby and I/O time-out.

This setting is used to use the  printer as a network printer. [Net-
work setting] allows setting of the following items. After changing
the items, terminate the key operator program and turn off the
main switch. Then turn on the main switch again after a while to
enable the setting.

Used to set the IP address of this machine when is it used under
the network environment using the TCP/IP protocol. (IP address,
IP net mask, IP gateway)

Factory setting is "IP address is automatically acquired (DHCP
Enable)."

When using under the TCP/IP protocol network environment,
[TCP/IP Enable] is set to Enable.

This setting is used when the machine is used under the TCP/IP
protocol network environment.

This setting is used when the machine is used under the NetWare
protocol network environment.

This setting is used when the machine is used under the NetBEUI
protocol network environment.

Used to reset all the setting items of NIC (Network Interface Card)
to the factory setting.

Terminate the key operator program and turn off the main switch.
Then turn on the main switch again after a while to enable the set-
ting.

This program is used to automatically adjust the color tone of each
color (cyan, magenta, yellow, and black). None of these adjust-
ments affect black and white printing.

The auto color calibration program enables automatic color grada-
tion correction when the color is off.

Note: The color gradation may not be sufficiently corrected after

one correction cycle. If so, execute the program again.

When the [AUTO COLOUR CALIBRATION] key is touched, the
following display will appear.

After the [EXECUTE] key is touched and a test patch printed, a
message appears asking you to begin automatic adjustment.
Place the test patch on the document glass as shown below and
touch the [EXECUTE] key.

Notes:

• Correct adjustment will not be possible if you use the test patch

that is printed for "Auto color calibration" for the copy function or
any other document. If you attempt to use the wrong test patch,
you will return to the message screen that asks you to begin
automatic adjustment. Be sure to place only the test patch
printed out above on the document glass.

• Lay approximately five sheets of copy paper that are the same

size as the test patch on top of the set test patch, and gently
close the original cover.

When a message appears informing you that auto color calibration
is completed, touch the [OK] key to end the procedure.

Note: Before using this program, make sure that the registration is

correctly adjusted. If the registration is not correctly
adjusted, perform [AUTO ADJUSTMENT] in "Registration
adjustment".

This program is used to reset the environment setting and the key
operator program printer setting to the default setting and to store
the current setting contents. If the setting contents are changed,
the stored contents can be recalled to reset the machine to the
stored setting contents.

This program is used to reset the environment setting and the key
operator program printer setting to the default setting. After execu-
tion of this program, terminate the key operator program and turn
off the main switch. Then turn on the main switch again after a
while to enable the setting.

This program is used to store the environment setting and the key
operator program printer setting in the memory. The stored con-
tents are not deleted even the main switch is turned off. To recall
the stored contents, use [Stored setting value recall].

This program is used to recall the setting contents stored with the
program of [Current setting storage] and reset the machine to the
recalled setting.

Configuration for 3-pin jumper is shown as follows.

Custom Setting dialog is automatically set with the Original Type as follows:

• When a user changes color dialog settings, "Original Type" is set Custom.

• When Original Type item is set to "Drawing (Thin line)", Screening item is set to "Automatic" on UI. However, in this case the drivers out-

put "Drawing" mode as PJL.
