Cause
Operation Check to see that the choice of roll or cut sheet is correct.
C1 Check to see if the leading edge of paper cut is not left.
C2 Check to see if suction holes are not clogged with paper dust or other foreign matter.
C2 The end of the roll is so sticky that it won't be separated from the paper tube.
C2 Check to see if preprinted or color paper is not used.
C2 Check to see if the leading edge of paper has been cut correctly.
C2 Check to see if the paper is not cockled, soiled or torn.
C2, C3 Check to see if paper do not jams between the platen and LF roller.
Does not occur with A4 plain paper → Not a multisensor fault
C2
None of the above
Flow 1 Check the multisensor for illumination and the paper position
With the top cover open,
load the same paper
Have the door switch released beforehand
Multisensor Illumination Check
iPF5000 Series
The multisensor cannot detect the leading of paper
(multisensor delay jam) when it has been successfully
detected by the LF_PE sensor.
Improperly mounted multisensor
C1 Low light intensity (due, for example, to soiling)
Paper with its leading edge cut remaining
Reflectance problem (thin tracing paper, semitransparent mat paper, etc.)
Soiled or broken
C2 Preprinted paper used
The end of the roll is so sticky that it won't be separated from the paper tube.
Curled leading edge of paper
Insufficient feeding force
C3
Stuck in the groove
Point to check
Check the paper has reached
under the multisensor, causing
it to illuminate
Paper has not reached
Paper has reached
iPF700 Series

Not illuminating
Replace the multisensor after making
sure it is improperly mounted
Replace the multisensor reference plate at the same time
