Current Caution Points

BSI No. F98B180 Page 2

03 ---> 04 When the ADU is used, if the paper exit sensor experiences a

waveshape breakage, the ADU stacking section will mistakenly detect a
jam.

04 ---> 05 When the PFP cassette tray is moving upwards, if the LCF door is

opened, the PFP tray motor will wrongly detect that this is an error.

05 ---> 06 During operation of the LCF tray, if the bypass feed unit is left open for

longer than 112 seconds, even if it is then closed, the LCF will not
restart its operation.
