Recently, I replaced the black imaging unit on a 4520 and a couple weeks later a code c2557 occurred. We are maintaining this machine as a favor to the business owner as this is a one off and the remainder of the machines fall under our dealership. As such we currently do not have manuals for this machine. I'm beginning to realize that we do not have the proper resources and will have to communicate this to the client.
At any rate can someone please walk me through the procedure to enter service mode,reset the imaging unit counter and calibrate.
Any help would be greatly associated.
