%2.5 Paper Jam Detection
2.5 Paper Jam Detection
The paper jam detection function supervises the paper state at power-on time and during printing. In the
event that a jam occurs, this function interrupts the printing process. If any of the following errors is
presented, recovery printing will be performed by removing the jammed paper ( by opening the upper
cover, removing the jammed paper and closing the upper cover).
Error
Cause of error
Paper input jam
• At power-on time, the paper is placed at the inlet sensor.
• After hopping operation is attempted three times, the leading part of
the paper does not reach the inlet sensor.
Paper feed jam
• At power-on time, the paper is placed at the paper sensor.
• The leading part of the paper does not reach the paper sensor within
a predetermined distance after the paper has reached the inlet sensor.
• The trailing part of the paper does not pass over the paper sensor
within a predetermined distance after the leading edge of the paper
has passed over the paper sensor.
• The leading part of paper does not reach the outlet sensor within a
predetermined distance after the paper has reached the paper sensor.
Paper exit jam
• At power-on time, the paper is placed on the outlet sensor.
• The paper does not pass over the outlet sensor within a
predetermined time after the leading part of the paper has reached the
outlet sensor.
• The paper size check with the manual feed specified considers the
reference size as free size.
Paper size error
Paper size error
• The size of the paper is supervised by the inlet sensor
1. It is detected that the paper does not pass over the inlet sensor 1
within predetermined range of distance.
• The inlet sensor 2 detects that the size of the loaded paper is A4 or
larger, or smaller than A4. The detected paper size differs from the
paper size set by command or menu.
• The paper size check with the manual feed specified considers the
reference size as free size.
