YMCKRGB Solid Fills

This test prints a single-sided, solid-fill print in all seven colors to show uniformity of fill. If colors
are uneven or wrong, see IQ8 - Color is Uneven or Color is Wrong.
Look for:
• Even, uniform fill throughout each print.
• Wrinkles or deformity of the paper.
• Proper ink transfer.
• White striping or banding.

Causes:
• Weak jets or improper Drum heating can cause uneven fills.
• To solve wrinkling, try different print media. Replace the Drum Maintenance Unit to correct
streaking. Check the Drum Temperature Sensor for debris build-up on the sensor. Check
to see if the Sensor is in improper contact with the Drum. See the Reverse Text test print.
As a last resort to fix wrinkling, replace the Transfix Roller
ule (REP 2.16), and Transfix Load Arms
• If there is poor transfer on one side, check to see if the transfix load arm assemblies are
moving easily. Clean any contamination that may be interfering with the transfix arm
assembly movement. If either of the transfix load arm assemblies are worn, replace the
worn load arm assembly.
• If there are repeating white stripes on the print, there may be a problem with the X-Axis
motion, see IQ17 White Stripes (Pinstripes).
