(This article is continued from the June issue.)
Once you're in UI Diagnostic Mode, choose 'System Settings', then
choose 'Common Settings', followed by 'Maintenance / Diagnostics'.
Here you'll find the most important menu. We'll talk briefly about
each of the menu items afterwards. Here are the things you'll see:
• Software Options (Allows an OEM rep to install upgrades for the
machine using passwords provided by the OEM using the machine's
serial number to generate the password. If a machine has options
installed, make sure to keep a backup of all passwords for that
machine's options.)
• Print Test Patterns
• MAX Setup (for color registration setup, etc.)
• Initialize Hard Disk (Warning… Don't use this without a full
understanding of what the procedure will do. You'll need to have
the full Service Manual on-hand. This will reformat partition 1,
eliminating all fonts & Job Templates)
• NVM Initialization (Warning… Don't use this one either without a
full understanding of what the procedure will do. You should only
use this stuff if you have the full Service Manual with you.)
• Component Control (Allows you to test Input & Output Components.
You will need a list of what each Component's Control Code is to
use this.)
• Sub System (Has a submenu choice: "Belt Edge Learn…" necessary
for whenever the IBT Belt is replaced)
• Delete All Data
• NVM Read/Write (Allows you to change NVM [Non Volatile Memory]
settings. You will need a list of what each NVM Setting Code is
before you can make use of this.)
• Registration (Registration of the image on the paper… read more
below)
• Adjustment / Others (Has a submenu with two choices:
“Machine ID / Billing Data Settings" & "Initialize HFSI Counter")
Obviously, this is quite a nice range of access. This is
refreshing after having seen the special software and computer
tools that some other models need for a technician to work on
them. People don't want to hear an independent tech say, "I can't
do anything for you. You have to call the manufacturer-they're the
only ones who have the equipment to work on your machine." It
sours the customer as well as the technician. These DC250 style
models do not have that problem, thank goodness.
Don't get me wrong; the authorized dealers who have the PWS
Laptops (the Portable Workstation) do maintain some significant
advantages. The main limitation you face without a PWS is that in
"Component Control" and also in "NVM / Read Write" (memory
settings), you can't browse through a list of codes to choose
from. For these two functions, you'll need to know which code you
are going to enter, so you'll be needing lists of these codes
(those code lists are going to mean two more ENX articles before
we're done with this topic). These lists are only viewable from
the PWS's screen.
Now, let's have a more in-depth look at each of the menu choices
from the list above:
Software Options: If you press "Software Options" followed by
"Keyboard", you can then punch in the password for the optional
service you are installing or re-installing. Then select 'Save'
followed by 'Reboot'.
Print Test Patterns: There are many available test patterns which
are useful for troubleshooting copy quality problems and for
isolating which board may be responsible for the symptom you are
troubleshooting. There are a wide range of patterns to choose
from…Each has its own 3 digit code. It appears that the list will
not show up onscreen, so you will need a list of the pattern's 3
digit codes or else you will be choosing blindly.

MAX Setup: The MAX setup menu contains the following stuff:
o
Procon ON/OFF Print
o IIT Calibration
o In/Out Manual Setup
o ATC Sensor Setup
o TRC Adjust
o Tone Up/Down
o Color Balance
Component Control: Here is where you'll go to test Input
Components such as sensors and switches and also Output Components
such as motors, solenoids, lamps, & clutches. You will need the
list of codes and their corresponding components to use this at
all since it does not appear in a menu on the Control Panel. We'll
cover the list in an abbreviated fashion in the next article. It
is a very lengthy list.
Delete All Data:
To quote the Service Manual: "This procedure deletes
user-defined/registered information and information recorded
automatically by the system from the hard disk, the ESS NVM PWB
and Buffer RAM".
NVM Read / Write:
This will need to be covered in a future article because the lists
of NVM codes are not browse-able from the Control Panel. The list
is very long. Until the list is available, you won't be able to
change any NVM Settings (you'd be working totally blind).
Machine ID / Billing Data Settings
There are 3 boards in the machine which all have the Serial
Number, Product Number and Billing Counters: the MCU NVM PWB (the
IOT or main machine logic board), the SEEP ROM (on the ESS or
Network Controller, known as Sys1), and the ESS NVM PWB (Sys2 on
the ESS or Network Controller). These 3 must agree with each other
(otherwise a Fault Code will be called… 124-310, 124-311, 124-312,
124-313, 124-324, or 124-325). This process is designed to
synchronize the three boards when one of them gets corrupted or
needs to be replaced. From "Machine ID / Billing Data Settings",
choose a board that has the correct data on it and select 'Start.'
Enter the correct Serial Number and then select 'Confirm'.
That'll have to be a wrap for this month. We will explore this
series further and get you some of the lists of codes needed to
test components and make memory adjustments.
