40930701TH DRAFT Vesion 47 /2.4 Paper Jam DetectionThe paper jam detection function supervises the paper state at power-on time and during printing.In the event that the following state occurs, this function interrupts the printing process. If any ofthe following errors is presented, recovery printing will be performed by removing the jammedpaper (namely by opening the upper cover, removing the jammed paper and closing the uppercover).ErrorPaper input jamPaper feed jamPaper exit jamPaper size errorDuplex input jam re-move the paperDuplex feed jam1 re-move the paperDuplex feed jam2 re-move the paperDuplex feed jam3 re-move the paperDuplex open jam re-move the paperError 83Cause of error• 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 notreach the inlet sensor.• 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 predetermineddistance after the paper has reached the inlet sensor.• The traiding part of the paper does not pass over the paper sensor within a predeter-mined 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 predetermineddistance after the paper has reached the paper sensor.• At power-on time, the paper is placed on the outlet sensor.• The paper does not pass over the outlet sensor within a predetermined after the leadingpart of the paper has reached the outlet sensor.• The paper size check with the manual feed specified considers the reference size as freesize.• The size of the paper is supervised by the inlet sensors 1. It is detected that the paperdoes 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 smallerthan 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 freesize.• Informs that a jam occurs in feeding papers to the Duplex Unit.• Informs that a jam occurs in retracting papers into the reverse roller within the DuplexUnit.• Informs that a jam occurs in reversing papers in the reverse roller within the Duplex Unit.• Informs that a jam occurs in impinge-feeding papers within the Duplex Unit.• Informs that the 1st tray is pulled out in paper-remaining state when feeding paperswithin the Duplex.• Informs that an I/F time-out occurs between the printer and Duplex.
