Docutech dC-951 Initialization 

By Raymond Cote

Ever wonder what happens during dC-951 Initialization?  And have you ever wondered what all those numbers really mean?  Hopefully this information will help you in troubleshooting copy quality issues and make your Docutech perform at its peak performance.  Actually, I was one of those techs that wondered what the heck was happening during dC-951 Initialization and also (secretly) praying that it would run to its completion with no problems or shutdowns.  I can’t remember the number of times I actually had my fingers crossed while this program did its magic in the Docutech, and I think it would be safe to say it happened often. Actually, dC-951 contains a number of programs that will automatically adjust all the parameters that will affect copy quality and performance.     

As you gain experience working on this family of printers, confidence on your part becomes more noticeable and you will even feel better about yourself. I know because it happened to me the same way after several months on the job.  

dC-951 Automatic Xerographic Setup

Before you enter Diagnostics to run dC-951, there are several things you should do to insure that the program runs to its completion.  Open both doors and make sure that all covers and panels are installed properly. Keep in mind that a light leak will affect the process, especially in the patch area, and can cause the machine to set up incorrectly.  Never run dC-951 with the front doors open or with any rear panels removed.      

Check tray 3 to make sure that four reams of white 20 pound 8 ½ x 14-inch paper is loaded and the paper supply is properly programmed. I prefer 14-inch paper because it allows you to see if the dicorotrons are properly balanced (top to bottom).  If this were a new installation or a new customer, it would be in your best interests to check the Dicorotron charge height (ADJ 9.7), balance (ADJ 9.8) and ESV height (ADJ 9.5) before running dC-951. The set-up procedure will be more precise if all the Xerographic components are clean and adjusted properly.     

It’s interesting to note that when you power up the printer, it will automatically run the dC-951 Xerographic set-up procedure
