Troubleshooting Guide
3-8
Cause Point to check Action
Operation Check to see that the choice of roll or cut sheet is correct. Explain.
C1 Check to see if the leading edge of paper cut is not left. Remove.
C2 Check to see if suction holes are not clogged with paper dust or other foreign matter. Remove.
C2 The end of the roll is so sticky that it won’t be separated from the paper tube. Explain.
C2 Check to see if preprinted or color paper is not used. Explain.
C2 Check to see if the leading edge of paper has been cut correctly.
Check the
cutter.
C2 Check to see if the paper is not cockled, soiled or torn.
Check the
paper.
C2, C3 Check to see if paper do not jams between the platen and LF roller. Flow 3
C2 Does not occur with A4 plain paper → Not a multisensor fault Flow 3
None of the above Flow 1
5. 【200C】Roll paper leading edge detection error,
【200D】Cut sheet leading edge detection error
Occurrence
conditions
The multisensor cannot detect the leading of paper
(multisensor delay jam) when it has been successfully
detected by the LF_PE sensor.
Multisensor
detection errors
C1
Improperly mounted multisensor
Low light intensity (due, for example, to soiling)
Paper with its leading edge cut remaining
Paper problems C2
Reflectance problem (thin tracing paper, semitransparent mat paper, etc.)
Soiled or broken
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
Failure causes
Paper feed problem C3
Insufficient feeding force
Stuck in the groove
Multisensor Illumination Check
iPF5000 Series iPF700 Series iPF8000 Series
Check the paper has reached
under the multisensor, causing
it to illuminate
With the top cover open,
load the same paper
Check the multisensor for illumination and the paper position
Paper has not reached
Flow 2
Have the door switch released beforehand
Not illuminating
Illuminating
Paper has reached
Flow 3
Replace the multisensor after making
sure it is improperly mounted
Flow 4
Replace the multisensor reference plate at the same time
Flow 1
