Cause:
This may occur if:
• Printing is done at low temperature or humidity
• To adjust the following settings, pre-register the type of paper in use as a custom paper. For details
about registering custom papers, see "Registering a Custom Paper", Paper Settings.
Solution:
Carry out the following sequence of procedures. Terminate the sequence as soon as the problem is
resolved.
Procedure 1: Specifying the area to be adjusted
1. Measure by a ruler or other device the length (in mm) of the area from the leading edge
of the paper where the print is faint or dense.
2. In [Advanced Settings] for the custom paper, specify the area to apply the transfer current
at the leading edge of the paper.
<Printing in black and white>
In 028: [Image Transfer Current: LE Leng.: BW], 040: [Paper Transfer Current: LE Leng.: BW]
and 062: [AC Transfer Mode: LE Leng.: BW], enter the value which is 5 mm higher than the
value measured in Step 1.
<Printing in full color>
In 030: [Image Transfer Current: LE Leng.: FC: K], 032: [Image Transfer Current: LE Leng.: FC:
C], 034: [Image Transfer Current: LE Leng.: FC: M], 036: [Image Transfer Current: LE Leng.:
FC: Y], 046: [Paper Transfer Current: LE Leng.: FC], and 065: [AC Transfer Mode: LE Leng.:
FC], enter the value which is 5 mm higher than the value measured in Step 1.
3. Print the image. Has the problem been resolved?
Yes Finished!
No Proceed to "Procedure 2: Increasing the current".
Procedure 2: Increasing the current
1. In [Advanced Settings] for the custom paper, make a note of the following values:
<Printing in black and white>
027: [Image Transfer Current: LE: BW], 039: [Paper Transfer Current: LE: BW], 060: [AC
Transfer Mode: Voltage: LE: BW], and 061: [AC Transfer Mode: Current: LE: BW]
