Code Details
1 One or more of the following sensors detected the presence or absence of paper at a
location other than the paper standby or registration standby position when the machine
was turned on, when a cover was opened and then closed, or when the machine
returned to normal operation from the energy save mode:
• Roll Unit 1 or 2 exit sensor (paper absent)
• Pre-registration sensor (paper absent)
• Bypass sensor (paper present)
• Exit sensor (paper present)
The machine will also signal an initial jam in these cases:
• If a cover is opened during printing
• If an error occurs in edge detection (paper size detection) or skew detection by the
DRESS sensor during the first phase of bypass printing..
2 The carriage does not return to the home position on the right side of the machine during
edge detection or printing due to an obstruction (torn, wrinkled paper).
8 During paper feed from Roll Unit 1, the pre-registration sensor did not detect any paper:
• After paper was fed long enough to feed the paper the distance between the pre-
registration sensor and the registration roller plus 100 mm
• After paper was fed long enough to feed the paper the distance between the paper
standby position and the pre-registration sensor plus 100 mm.
