Test Print Examples (Continued) 8: YMCKRGB Solid Fills These seven prints show uniformity of fill. If colors are uneven or wrong, see "Color is Uneven or Color is Wrong" on page 5-16. Look for: 1. There are even, uniform fills throughout each print. 2. 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: 1. Weak jets or uneven drum heating may cause uneven fills. 2. 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. 9: Drum Seal This print is not supported for this system. 10: Manuf. Paper Path These prints are used by manufacturing and engineering only. 9923-119 5-40 WorkCentre C2424 Service Manual
