Document loading error

(1) The document rear sensor detects no leading edge of a
document within 10 seconds from the start of document
loading operation.
(The document rear sensor stays OFF even after the
document has been fed when the document front sensor
was ON.)
(2) The loaded document is too short.
(Since the document is shorter than the distance between
the document front and rear sensors, the document front
sensor is turned OFF before the document rear sensor is
turned ON.)
In the scanning compensation data list printed by the
maintenance-mode function code 05 (refer to Chap. V, Section

The ink dot counter (for cyan, magenta, yellow, or black) in the
EEPROM on the head PCB has counted up the specified
number of dots, meaning near empty of ink. Even if any of
these messages is displayed, color printing is still possible.
The ink dot counter (for cyan, magenta, yellow, or black) in the
EEPROM on the head PCB has counted up the specified
number of dots, meaning that the ink has run out. Once any of
these messages is displayed, color printing is no longer
possible. (If black ink remains, printing of the received data
record or monochrome copying is possible.)
NOTE: For checking how much the black ink remains
accurately, the controller compensates the ink dot count with
the black ink empty sensor.
Any one of the four ink cartridge sensors detects no ink
cartridge loaded.
The temperature inside the equipment has dropped to 5.5°C or
below after two hours of powering-on state, or it has dropped to

scanner unit is warming up; that is, for approx. 3 minutes after
the fluorescent light comes on.
The temperature inside the equipment has exceeded 48°C.
