10. Troubleshooting Q&A
If you think the machine is out of order, check the following first.
Q1 The display panel and all pilot LED lamps do not light up when you turn on the power switch.
• Is the power cord properly connected?
• Is the outlet live with electricity?
○ If the LED lamps do not light up after you have checked the above, the machine is out of order.
Q2 The machine does not work when you press the Start Key.
• Is an error displayed on the display panel?
• Is the Ready/Clear LED lamp (green) lit?
(Did you forget to release the error by the Ready/Clear Key?)
• Is 0 (zero) displayed as the number of products set under the preset mode of the counter?
○ If the machine does not start even after checking all of the above, the machine may be out of order.
Q3 The machine does not start feeding the paper when you press the Start Key.
• Is the paper too thick? (Paper must be no thicker than 0.30mm and no heavier than 302g/mm
2
.)
• Are the edges or corners of the paper heavily curled?
• Is the paper stained with oil or powdery substance?
• Is the friction on the paper surface too strong or weak?
• Is the pick-up roller or separation pad worn out?
→ In this case, see “8. Maintenance.”
○ If it does not feed paper even after checking and correcting all of the above, the machine may be out of
order.
Q4 Paper stops moving ahead after moving slightly.
• Are you using nonstandard paper (highly transparent paper, dark color paper, paper that reflects light
diffusely)? (The sensor cannot detect the edge.)
○ Use suitable paper.
Q5 The machine has started to feed two sheets or more, even though normal paper is used.
• If the sheets stick together because of static electricity:
→ Fan the stack of sheets and reload them.
• Atmospheric humidity is too low → Increase humidity (using a humidifier, etc.).
• Is the machine properly grounded? → Ground the machine securely.
• Is the separation pad worn out? → In this case, see “8. Maintenance.”
○ If these procedures do not solve the problem, the machine may be out of order.
