Xerox Phaser 8550 series 05.004 code

Y axis subsystem error. Drum turns which tells me vertical axis motor functions ok. Maint roller kit lifts and engages and disengages normally. Found waste ink under the maint kit and removed it and then the printer started up normally and was fine for one day. Started the printer up again today.......same error code has returned. Since the maint kit lifts normally and based on the fact the printer started normally and worked for one day....I assume that the dm camshaft is ok. Printhead moves freely both vertically and horizontally. When you turn the printer on if it doesn't throw the code in the first 30 seconds, the printer starts up and works great until you turn it off and let it cool down and restart it. If you turn it off and a few minutes later start it back up again it initalizes fine. Only after completely cooling down and restarting does this occur. Any ideas much appreciated.

Inspect the drum pulley, y-axis belt and y-axis motor for oil contamination. Motor and pulley can be cleaned with alcohol. If the belt is contaminated with oil, the belt should be replaced. If the drum assembly is found to be the source of the oil, the drum assembly should be replaced.
