Question about HP LaserJet 3600n Printer
HP LJ3600 Constantly Calibrating SOLVED.
Hope this helps. I have nine HPLJ3600 printers. Four of them developed this fault. After much head scratching I decided to strip one down. I found the fault to be a thin layer of dust on the laser scanner mirror for the red and yellow images. There are four mirrors in the scanner two of which are upward facing and where dust settles. You will have to strip the scanner unit out to get at the scanner. and physically remove the dust. This proceedure also resolved the fault on the remaining three printers. The factor of dusty environment for these printers was the cause. The office printers are all fine. The forced air ducting seems to take the dust laden air across the scanner unit which is not sealed thereby causing the problem. After six months the problem has not returned as yet but all I will do next time is a strip and clean. (there are a couple dozen screws to come out and replace.)

Could be a bad toner cartridge. What did you do prior to the constant calibrations?

If the calibration is taking a long time that can be related to the ITB belt. If the printer doesn't think that the calibration is correct it will keep trying until it sees a correct image(color)

No guarantee this will fix your problem, but the last time I experienced this problem it ended up being one of the toner cartridges. I replace her refurb. toners to OEM brand.
