13.  the Faults which you may run into in your adventures     Ok    Iam told these machines are easy to work on as far as physical mechanics are concerned  How easy   Well there are 3 maintenance drawers  One with the Drum Cartridges and Developer units  a second one with the  Transfer Belt Assembly and Belt Cleaner Assembly  and a third drawer with the 2  BTR  Transfer Roll Assembly   and Fuser Module  A novice can take the DV Unit out if it came down to it  This is unusual and extremely  refreshing  An engineering marvel by all means     The various groups  or let   s call them    families     of machines within this    DC250 style     have many  similarities but naturally there are differences as well  They share very similar fuser modules  toner cartridges and  drum cartridges  so internally they are very similar    read near the end of this write up about the differences  between models  The diagnostics are also very similar from family to family  except that the method to enter the  diagnostic mode changed early on in the WC 7655 group of models  v2 software   We   ll cover the two ways to get  into diagnostics after the fault code list     The Fault Codes and their    RAPs     Repair Analysis Procedures  in the Service Manual take up a  whopping 900   pages    so this list will have to be severely abbreviated  The plan is to stick to the codes which are  more important to field techs  The codes are all laid out as 3 digits  the    Chain        followed by a dash and then 3
14. 00     Next let   s look at the part numbers and differences between various supplies in the DC250 style  the yields  reported in the Service Manuals are not consistent from model to model even if the part number of the supply is  identical    the estimated yields given are taken from the earlier literature on the DC250 model which are lower  stated yields than the newer models    literature  I am told that the yields are dependent on factors such as how many  pages are run in an average job    machines which run lots of copies or prints per job will end up running higher  yields for the drum ctgs before they    tine out    than machines which run only a few pages per job     Supplies    e Toner Cartridges    There are several versions of the toner cartridges  depending on the model of the machine  the DC250  DC242  7655   amp  7755  families share the same ones with one another  but the 550 family has a  unique set as does the DCP700 family    the J75 family shares the same  toner ctgs with the DCP700 family   Also  for the newer models  DCP700   550 560 570   amp  J75 C75   there are also several    markets    which require  different toner cartridge part numbers  If you install the    wrong    version  the  machine will reject the toner  There is a    Metered Plan    which can be found  worldwide on machines which were initially set up to be under Service  Contract  Then there is a    U S  Sold Plan    and a    DMO Sold Plan     It can Toner Cartridge   Yellow  get pretty
