Cause/Remedy
• There is a possibility that an external signal is being
applied during reading.
• Ensure that the device is protected from external influ-
ences during reading, and perform exposure again.
• This can happen when the lead or shielding material is
in a blank section.
• This phenomenon happens only under very specific
conditions, and it can be resolved by moving the shield-
ing material as far as possible from the subject or by
restricting the exposure field.
• If this continues to occur repeatedly, please contact the
plant or Development.
• Return the plate with warping or peeling to the REGIUS
Console.
• If the problem repeats with different plates, adjust the
peel detector roller.(p.117)
• Plate warping or peeling can lead to contact between
the plate and the detection roller.
• Light may be leaking in the device.
• Reassemble the exterior covering or darken the room,
and then take a solid image to confirm quality
