The DC12 remains
one of the most respected full color machines to roll out of
Xerox's warehouses to date. The image quality is superb,
especially when it comes to glossy output, and the machine is
particularly suited to handling heavy paper such as card stock.
This article is continued from the last issue and will cover some
fault codes and detailed troubleshooting tips.
* 03-380 IBT Belt Patch not seen by the TR0 Sensor The 03-380 code
means that the machine did not sense the signal from the "TR0"
sensor. That is a sensor which looks for a reflective patch on the
IBT Belt to come around at the right times. The patch is a small
square reflective sticker near the edge of the IBT Belt on the
outside of the belt. You'll want to start by making sure the
square reflective patch on the IBT Belt is clean and reflective.
The patch is located near the edge of the IBT Belt on the outside
of the belt. The Service Manual also tells you to double check to
make sure the Drum Cartridge is properly seated. Then you'd want
to make sure none of the following plugs are loose or
disconnected: P/J 398 on the Half Tone PWB, P/J 345 on the LDD PWB,
P/J 416A on the IOT Drive PWB, P/J 140 on the TR0 Sensor, and the
"Double Plug" P702A. Hopefully one of these things will solve the
problem.
** 09-354 (Black), 09-355 (Cyan), 09-356, (Magenta) 09-357
(Yellow) When any of the 4 "Toner Dispense Broken" Status Codes
come up, it means that the machine detected a toner dispense
problem with a particular color of toner. First, make sure that
the toner cartridge which relates to the code actually has toner
in it, and that the toner dispense coupling which stirs the
cartridge is in good condition. Once you are convinced that there
is toner in the cartridge, here are some things to check out:
1. Check
the following Plug / Jacks (P/J) to make sure that they are seated
ok and there is no damage:
P/J 432 & P/J 433B
on the Dispense Board.
P/J 421B on the IOT Drive Board.
The P/J for the Cartridge Motor of the color you are
troubleshooting.
The P/J for the Low Toner Sensor of the color you are
troubleshooting.
2. Check
the Toner Dispense Auger for damage.
3. Reset
Non-Volatile Memory (NVM) codes 776-063 & 776-371 to '0'. This is
done by entering diagnostic mode (Turn on the power, then press
and hold down the '0' button while pressing 'Start'. The screen
will prompt you for an "Access Number". Use the keypad to enter
'6789' which is the default Access Number). Use the menu to select
"NVM Read/ Write". Enter the first part of the code (the part
before the dash) which is called the "Chain" followed by 'enter',
then the second part of the code (known as the "Function",
followed by 'enter' again. If the value shows up as '1', enter a
'0' and then confirm your selection on screen. Here are the
appropriate NVM values to reset depending on which color you are
dealing with:
Black Toner:
reset NVM 776-063 & 776-371 to '0'
Cyan Toner:
reset NVM 776-062 & 776-374 to '0'
Magenta Toner:
reset NVM 776-061 & 776-373 to '0'
Yellow Toner:
reset NVM 776-060 & 776-372 to '0'
Keep in mind that
resetting these codes will not cure the cause of the problem. If
the problem that triggered the code is still there, the Status
Code will return.
4. The
Toner Cartridge Motor or Toner Dispense Motor might not be
functioning (either due to a motor problem or wiring or board
problem). To test the "Toner Cartridge Motor" and the "Toner
Dispense Motor" for each color, here are the codes to run from
"Component Control" in Diagnostics
Mode:
Black:
009-011 (Toner Cartridge Motor K), 009-031 (Toner Dispense Motor
K)
Cyan:
009-014 (Toner Cartridge Motor C), 009-034 (Toner Dispense Motor
C)
Magenta:
009-013 (Toner Cartridge Motor M), 009-033 (Toner Dispense Motor
M)
Yellow:
009-012 (Toner Cartridge Motor Y), 009-032 (Toner Dispense Motor
Y)
*** 09-363 Rotary Home Position Failure - The machine did not see
the Developer Rotary System come to its home position properly.
There is a rotary system which has the 4 developer units on it. It
rotates to move each color into position adjacent to the drum
cartridge as the machine develops each layer of color. This
problem can be caused by a problem with the Drum Cartridge not
being seated properly, or it can be a sensing problem, or possibly
something binding or broken in the drives which move the rotary
system.
1.) First check that the Drum Cartridge is seating
properly. Make sure that it is latching securely into position (if
a Developer Unit can't move into the correct spot because the drum
cartridge is out of position and gets in the way, this code can
show up).
2. ) Check these Connectors to make sure they are fully
seated:
P/J420, P/J 418A, P/J 412A on IOT DRIVE PWB (Driver Board)
P/J 260, P/J 261, P/J 262 on ROTARY PWB (Rotary Board)
P/J 110 on ROTARY HOME POSITION SENSOR
3.) Make sure the Rotary Home Position Sensor and Rotary
Latch Solenoid are installed properly and test them: Sensor =
Component Control (Dc330) Code 009-220. The display will show "H"
if at the home position.
Rotary Latch Solenoid: Component Control (Dc330) Code 009-018. See
if it actually actuates properly.
4.) Check 2 fuses on the Rotary Board (Rotary PWB). If one
or both fuses are blown, replace as needed. If it blows again,
replace the Rotary Board.
5.) Test the Rotary Motor system (Dc920). Select Yellow,
Magenta, and Cyan. See if the Rotary Motor system turns smoothly.
If not, check the Rotary Drive Components (shown on PL 6.1 & 6.6
in the Parts List) These parts include: Rotary Motor: 127K28490,
Rotary Latch Solenoid Assembly: 121K16400, & Rotary Gear Assembly:
68K86932
One more bit of info before we turn in for the month. Setting up
the machine so it will communicate with the Fiery (network
controller) can prove very important. Below is information about
the memory settings you'll want to know about.
FIERY (Network Controller) Setup Info:
Before you can make use of a Fiery, Cobra, or other Network
Connection equipment, you need to set the DC12 machine up to
enable the printing and scanning options.
Record Existing Settings:
First and most importantly, you should check and record the
existing memory settings. If you look in Drawer #1, there is a
pocket in which you will hopefully find the Log Book for the
machine. Go into the diagnostics (read below) and look at the
settings in the NVM (Non Volatile Memory) Read / Write to make
sure they all match what's shown in the Log Book. If you don't
find a Log Book, then make one. Because the NVM Settings are not
in a scrollable menu, you will want to have a list of the Memory
Setting codes with you.
To get into the NVM settings, first enter the User Interface (UI)
Diagnostic Mode. Turn on the power then while holding down the '0'
button, press 'Start'. The screen will prompt you for an "Access
Number". Use the keypad to enter '6789' which is the Default
Access Number. Choose "NVM Read / Write" from the menu.
Set the Configuration of the machine:
Enter NVM code 752-008. By default the setting is "0" for copier
only. Change it to "2" for "Copier, Printer, Scanner" or "4" for
"Printer".
Timeout Settings for Network Controller Communications:
Check these settings to help prevent "No Print" problems caused by
communication time-outs.
759-004 Configuration Page setting: For a Fiery set it to "0"; for
a Cobra set it to "1".

Fiery Setup
/ Diagnostics:
X12 Fiery: Find the 4 buttons in a vertical row on the right. Hold
down the bottom button in that vertical row while turning on the
power.
XP12 Fiery: Hold
the top and bottom buttons in the right vertical row of buttons
while turning on the power. The default password for setups, etc.:
"Fiery.1" (capital "F" in Fiery).
Note: One of the more useful functions is "Restore from Backup".
Use this if you suspect any corruption in the Fiery's memory. If
the Fiery comes back to life but is noticeably sluggish, beware
that the Fiery's Hard Disk Drive may be beginning to fail.
Finding Drivers for Printing and Scanning:
On the Xerox website (www.xerox.com), choose "Support and Drivers"
from the home page menu. Choose "Color Printers", and then "DocuColor".
Then in the right column, find "DC12" and choose the appropriate
Fiery version's link to its "Support and Drivers". For the Scanner
Drivers, scroll down to a separate heading for "Utilities &
Applications" for the scanner drivers.
All right then… that should do it for the time being. I hope it
will prove helpful to many of you. Happy New Year everyone!
