TROUBLESHOOTING Whenever the machine stops or operation is not possible, check the operation panel display for messages.

In cases where this information is not enough, check the list below for more information. This section describes problems concerning copier features. For troubleshooting specific problems related to printer, facsimile, or network scanner features, see the separate manuals provided for them. For problems related to other peripheral devices, see chapter 5 of the "Operation manual (for printer operation and general information)". Problem Machine does not operate.

The exposure level in the AUTO mode can be adjusted using a key operator program. Contact your key operator. (See page 33.) Cancel the PHOTO exposure mode. (See page 15.) Clean regularly. (See page 4-12 of the "Operation manual (for printer operation and general information)".) Clean the original scanning window. (See page 4-12 of the "Operation manual (for printer operation and general information)".) Use a clean original. Rotation copy functions only if the machine is either in the auto paper select mode or in the auto image mode. (See pages 8 and 16.) Set the original properly. (page 7) Use the auto image function to select the appropriate copy ratio based on the original and copy sizes. (See page 16.) Place the original face down in the document feeder tray or on the document glass. (See page 7.) When using the document glass, set the originals from the first page one sheet at a time. When using the automatic document feeder, set the originals with the first page down. Press the [CA] (clear all) key to cancel the current job. If the data amount exceeds the limit when using the pamphlet copy or multi shot copy which requires scanning of all originals, scanning will be canceled and copying will not be performed. If you install a hard disk drive, the storage capacity will increase. 30
