YMCKRGB Solid Fills

Primary Solid Fills 10x

These seven prints show uniformity of fill. If colors are uneven or wrong, see
"Color is Uneven or Wrong" on page 5-9.
Look for: Even, uniform fills throughout each print.
Wrinkles or deformity of the paper itself caused by the print process show up
in duplexed solid fill prints at Standard or Enhanced resolutions. To test for
wrinkling, print the YMCKRGB prints in duplex mode at the Enhanced or High
Resolution/Photo mode. Typically wrinkling appears in the secondary colors.
See the blue and green solid fills in the illustration to the right.
Causes: Weak jets or uneven Drum heating may cause uneven fills.
To solve wrinkling, try different print media. Replace the maintenance kit 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, transfix load module, and transfix load arm.
This item enables you to print 10, CMYK solid fill prints. These prints are used
to determine if the Drum or transfix roller have a defect.
Drum defects do not move in the X-position print-to-print; but it does move into
the Y'-position print-to-print. Drum defects do not repeat down the page.
Transfix Roller defects do not move in the X-direction; but, these defects
repeat every 4.58 in. (11.63 cm) down the length of the page. Many Transfix
Roller defects will be most visible on duplex solid fills
