Texture of filled image areas appears rough.
Cause:
Paper with a smaller width leaves more of the roller exposed where there is no paper, and this allows leakage of charge from the transfer electrical field thus reducing the efficiency of image transfer. This effect can also occur when:
- Ambient temperature and humidity are low
- Paper is extremely thick
- Electrical resistance of paper is high
- Duplex printing (occurs on Side 2).
- Please remember that before it can be used, paper requires setting by the operator, especially if adjustments for a different type of paper (custom paper) are used.
Solution:
Check duplex prints and determine on which side the problem occurs. If the problem is occurring on both sides, do the adjustment for Side 1 first and then the adjustment for Side 2.
- In Advanced Settings for the custom paper in use, check the settings for Paper Transfer Current Setting: Side 1 (SP2-811-001 to 100: PTR Current:Side1 Custom Paper 001 to 100), or Paper Transfer Current Setting: Side 2 (2-812-001 to 100: PTR Current:Side2 Custom Paper 001 to 100).
Either or both settings at the upper limit?
Yes
Go to Step 6
No
Go to the next step.
Are the white spots on labels allowed for use by the client?
Yes
Go to the next step.
No
Go to Step 6.
- Raise the transfer current setting by 5 points.
Print the image. Is the problem resolved?
Yes
Finished!
No
Repeat Steps 2 to 5.
Can you change the orientation of the paper (SEF to LEF, for example), or change the paper size (A4 SEF to A3 SEF)?
Yes
Go to the next step.
No
Use a different paper.
- Use wider paper.
- Restore the image transfer voltage to its default setting, and then go back to Step 4.
- If the problem is not resolved, consult the product specialist.
- Raising the image transfer voltage can cause white spots to occur in filled areas, so keep this in mind when doing the adjustments. If white spots appear, make some output samples and choose the best from among the test prints and use those settings.
