Uses an algorithm to compensate for mechanical incorrect registration in the printer. When small black text or 
fine black lines are being printed, the printer checks to see if they are being printed on top of a colored 
background. If so, rather than remove the color from beneath the black content, the printer leaves the color 
around the edge of the text or line. The hole in the colored region is reduced in size, which prevents the 
characteristic white gap that is caused by incorrect registration.
Values include Off and numbers 1–5 (the default is 2). Values 1 through 5 indicate the amount of color remaining 
beneath the black content. The default is each setting increments by 1/600 of an inch. The more inaccurate the 
registration setting, the higher the setting needs to be adjusted. Selecting Off disables color trapping.

Selections are Off and the values between 100 and 1000 in increments of 50. The default is 500 pages.
If the printer exceeds the set value while printing a job, it completes the current job and any other jobs received 
while printing the current job before it initiates a calibration. The printer does not cancel or suspend an active job 
in order to perform a calibration. If a user is using the menus, including the Configuration Menu and the 
Diagnostics Menu, an automatic color adjust calibration does not occur.
When an event other than page count triggers this calibration, the count that monitors the maximum number of 
pages printed will be reset. For example, if the user replaces an empty toner cartridge, the next time the printer 
is started, it will sense the new cartridge and perform the automatic color adjustment, even though the page 
counter for Auto Color Adj is fewer than required. The Auto Color Adj page counter is then reset.
