If it went dead almost immediately after pressing the Start pad, that\'s usually a shorted high-voltage capacitor.

If it went dead a few seconds after pressing the Start pad, that\'s usually a failing high-voltage transformer.

Here are some links you or a friend can use for test help, but read their safety warnings first:

You can probably find an exploded view by entering your FULL model number here: http://www3.sears.com (the 3 is correct)

No numbered touch pad for use setting clock


I think on this one you press the CLOCK/TIMER pad, then enter the desired time using the 10 MINUTES, 1 MINUTE, AND 15 SECONDS pads then press CLOCK/TIMER again.

If that doesn;t work, press STOP / CLEAR then try the above again.

Let us know if it does not work.

Group code


I believe what you want is at the bottom of this list.

If you frequently send faxes to the same group of telephone numbers, you can assign these numbers to a group.
Only Speed Dial and One Touch numbers can be assigned to a group. A maximum of 25 Group Numbers (WorkCentre Pro555) / 50 Group Numbers (WorkCentre Pro575) can be assigned (in the range 1-1999). Preset group numbers can also be used for polling.
The following information is included below:
  • Create a new group
  • Add numbers to an existing group
  • Delete numbers from an existing group
  • Delete an existing group
To print the Group Phonebook, see the Related Items below for additional information.
Create a new Group:
  1. From the Standby Mode, press the [Menu] (up arrow) button on the Control Panel, then press [3], [3].
  2. Use the numeric keypad to enter the Group Dial number (1-1999) you want to assign to this group.
  3. Press the [Enter] button. The screen will display a name.
  4. Use the numeric keypad to enter the Group Name (20 characters maximum), then press [Enter].
  5. Press the One Touch button you want to include in this Group, or enter the Speed Dial number, then press [Enter].

    NOTE: The One Touch and Speed Dial numbers must already be programmed. See the Related Items below.

  6. Repeat step 5 to enter additional numbers.
  7. When you have entered each number you want to include in this group, press [Enter].

    NOTE: Group Transmissions are easier if a group is linked to a One Touch button.

  8. To assign this group to a One Touch button, press the One Touch button. To skip this step, press [Enter].
  9. Press the [Exit] or [Stop] button to return to the Standby Mode.
To add numbers to an existing Group:
  1. From the Standby Mode, press the [Menu] (up arrow) button on the Control Panel, then press [3], [3].
  2. Use the numeric keypad to enter the Group Dial number (1-1999) you want to assign to this group.
  3. Press the [Enter] button.
  4. Press [2] to modify this group.
  5. Use the numeric keypad to enter a new group name, then press [Enter], or press [Enter] to retain the old name.
  6. Press the One Touch button you want to include in this Group, or enter the Speed Dial number, and then press [Enter].

    NOTE: The One Touch and Speed Dial numbers must already be programmed. See the Related Items below.

  7. Repeat step 6 to enter additional numbers.
  8. When you have entered each number you want to include in this group, press [Enter].
  9. Press the [Enter] button.
  10. Press the [Exit] or [Stop] button to return to the Standby Mode.
To delete numbers from an existing Group:
  1. From the Standby Mode, press the [Menu] (up arrow) button on the Control Panel, then press [3], [3].

  7. Press [1] to delete this number.
  8. Press [Enter] to delete the number, or press the [Exit] or [Stop] button to exit without deleting number.
  9. Repeat steps 5 through 7 to delete additional numbers.
  10. When you have deleted each number from this group, press [Enter].
  11. Press [Enter].

User Code


You may want to print this out because it is long.
Adding codes
Adding codes is really pretty simple.
First Add a System Manager code:
  • Press the 'additional functions' button to the right of the touch screen.
  • Press the 'system settings' button ON the touch screen.
  • Press the 'system manager settings' button on the touch screen.
  • Press the 'system manager' button on the touch screen and then use the touch screen to enter the system manager's name. Press 'done' when you have finished.
  • Press the 'system manager id' button on the touch screen and use the numeric keypad located to the right of the touch screen to create the id.
  • Press the 'system password' button on the touch screen and enter a numeric password for the system manager. YOU SHOULD MAKE A NOTE OF THE SYSTEM MANAGER ID AND PASSWORD, AS THIS WILL BE NEEDED TO CHANGE SETTINGSLATER.
  • Press 'next' on the touch screen.
  • Press 'email address' to add an email address for the system manager.
  • Press 'contact information' to add an extension to reach the system manager at.
  • Press 'ok' to complete the process.
  • Press 'done'.
Next add user codes:
  • Press the 'additional functions' button
  • Press 'system settings' button on the touch screen.
  • Press 'department id management' on the touch screen.
  • Press the 'on button' on the touch screen.
  • Press the 'store dept. id / password' button on the touch screen.
  • Press 'store' on the touch screen.
  • Press 'department id' on the touch screen and then enter a numeric code using the keypad.
  • If you want additional security you can also set up a password by pressing 'password' on the touch screen and, using the numeric keypad again, enter the password. The password can be left blank if desired.
  • Additionally you can set an impression limit for that user by pressing 'impression limit' on the touch screen.
  • Press 'ok' on the touch screen to add the user.
  • If you wish to limit impressions then you must press the 'limit impress.' Button on the touch screen.
  • If you want to add more users at this time go back to step 6.
  • Press the 'done' button.
  • Press the 'off' button at the bottom of the touch screen next to 'accept jobs with unknown id.
  • Click 'ok' to complete the process and start using the copier or go back to step 5 to add more users.
After this process users will have to enter a user id to use the machine. At the end of the copying process users should press the 'id' key located at the bottom right of the keypad to logout. The machine will automatically log users out if there has been no activity for a few minutes and this can be changed by pressing 'timer settings' in the additional functions.
While this seems like a lot it actually doesn't take very long to do. There is a far more elegant set of instructions in the 'reference guide' that came with the machine, which includes pictures, and starts on page 4-2.
