Please read this disclosure before proceeding.

The printer should be stabilized before performing the followingadjustments. If the printer has not been operating for a period oftime, it is recommended that at least 50 sheets of 11x17 images beprinted before starting the adjustments. Determine if it is possiblefor your customer to manage jobs so that a non color cri tical jobcan be run before performing the following procedures. This shouldsuff iciently stabilize the printer and reduce any additional cost tothe Customer.

In the RIP calibration process, step 16-23, CUSA suggests using the21 sorted patches for the measurement page. Overall this should

provide satisfactory image quality. If your customer is still notsatisfied with the printer output using the 21 sorted, performing thecalibration procedure using the 34 sorted or either of therandomized measurement pages may provide more satisfactoryoutput.
