Since we replaced a colour cartridge, the printer
This is an answer to most of the problems of "continuous calibration" in the HP 3600.
When the printer begins to constantly calibrate and falls in line so we have a problem, there are several causes for that problem and must be discarded from the simplest solution to the most complex.
Let's begin:
SOLUTION 1: The first thing to do is turn off the printer, and remove the cartridges, toner dirty or if the internal parts of the printer remove the excess, if there is dirt in the transfer belt clean.then close the front cover and turn on the printer without cartridges. then open the lid, place the magenta cartridge, and close the lid again, and so putting the four cartridges. If the problem persists try the next solution.
Solution 2: We must be alert to any strange noises in the printer, it is likely that one of the sticks is failing, if we are a strange noise came from, and replace the cartridge.
SOLUTION 3: There are times that it is software problem can be solved with a "COLD RESET" to do this we must turn the printer, and press the green button several times in the main menu until you see some options, navigate to the Down Arrow button until COLD RESET appears, press OK. the printer will restart and initialize. then restart and probably reached OK status.
SOLUTION 4: Sometimes by changes in temperature and environment where the printer is out of calibration sensor, to do a need to upgrade the firmware of the printer, usually ends the problem here. To download the firmware of the printer with the improvement due to "Countermeasure for multiple Successive Causing Environmental Sensor Calibrations." is in the following link:

SOLUTION 5: If any of these options serves, it is likely that the mirrors of laser printer are dirty, this requires us to print a sheet to observe defects in print (moved, blurred, misplaced shadows), if any of these defects appear we disassemble the printer for cleaning the laser ... in this link are instructions
