The highly popular Xerox DC250 style has proliferated into a whole range of models, each with their own versions of the color drum cartridges.\u00a0 It is high time we revisited this type of drum cartridge and brought all of these new models into the fold. We\u2019ll get into the differences, talk about \u201cbest practices\u201d and revisit the rebuilding instructions.<\/p>\n

Here are the many cartridge reorder numbers and their respective models:<\/p>\n

Many folks have found that you can maximize the yield by cleaning up the cartridge and replacing the CRUM chip and charge roll after the first cycle. In most cases this will nearly double the cartridge\u2019s initial yield.\u00a0 Then when the drum is actually worn out, you can do a full rebuild.\u00a0 Good aftermarket parts (drums, blades, charge rolls (PCR) and CRUM chips, as well as PCR cleaning rolls) are all available these days.\u00a0 Or you can pick up a cartridge rebuild kit which includes all of those parts.\u00a0 Go green!\u00a0 It makes for good common sense to maximize the yields on these cartridges rather than letting them go to a landfill too early.<\/p>\n

The best success stories surrounding rebuilding these drum cartridges tell of setting up a workbench where one or two techs in a dealership can rebuild cartridges for the company. This allows the technicians to deliver the cartridges as ready to go units.\u00a0 It simply makes the tech look good. They don\u2019t have to make a big awkward mess at the customer\u2019s location, complete with vacuum cleaner blaring.\u00a0 Having a few hand-picked techs doing these all the time makes them experts at the process.\u00a0 Most of them do cartridges for a few hours and then hit the field to answer their usual calls.\u00a0 It also proves to be far more efficient to work in a facility.\u00a0 A clear workspace with all of the necessary tools handy is priceless.\u00a0 Odd spare parts and extra used cartridge cores are within easy grasp if something unusual needs replacing.\u00a0 When setting up a workbench, it is important to have a machine nearby to test cartridges before they go out to the field.\u00a0 This allows the techs to catch any mistakes and to solve potential problems without inconveniencing your customers.<\/p>\n

Now let\u2019s see what makes the many versions of the cartridges different from one another.\u00a0 The primary difference which makes each cartridge version unique is the CRUM chips which are found inside the rear end cover of each cartridge.\u00a0 The drum count is kept on the drum cartridge by this RF Connector CRUM (Radio Frequency, Customer Replaceable Unit Monitor).\u00a0 Replacing that CRUM will reset the drum count.\u00a0 Each cartridge version has its own version of the CRUM chip, so make sure you order the correct one for the machine you\u2019re working on:<\/p>\n

DC250CNC (for DC250 version 13R603 cartridges),<\/p>\n

DC700CNC (for DCP 700 version 13R565),<\/p>\n

550CNC (for 550 version 13R664),<\/p>\n

5000CNC (for DC5000 version 13R649),<\/p>\n

J75CNC (for C75 \/ J75 version 13R672).<\/p>\n

There is one other difference which sets the original DC250 version (13R603) apart from all of the newcomers.\u00a0 All of the new versions are shaped slightly different in that they have an additional piece on top. Instead of using a stationary brush to clean the charge roll as was found in the DC250 version, a cleaning roll has been added to the newer designs.\u00a0 This turns out to be a substantial improvement as it helps the charge roll last a lot longer.\u00a0 Fortunately, the drum, blade, and charge roll are interchangeable among all of the versions.<\/p>\n

PROCEDURE:<\/strong><\/span><\/p>\n

    \n
  1. Remove the Rear End Cover<\/strong> (1 Phillips head screw (see Photo #2).\u00a0 The RF Connector CRUM sits in this cover.\u00a0 You\u2019ll need to replace it to reset the drum count (see below for details).\u00a0 The rear finger pull comes right off as does the charge roll contact pin.<\/li>\n
  2. Remove the Front End Cover<\/strong> (1 Phillips head screw).\u00a0\u00a0 Now the front finger pull will fall right off.<\/li>\n
  3. If the cartridge is one of the newer versions, remove the cleaning roll\u2019s cover<\/strong> from the top of the cartridge by pivoting it to the left to lift off (see Photo #3).<\/li>\n
  4. Remove the Charge Roller Assembly.<\/strong> You can release it by simply rocking it to the right and lifting off (see Photo #4).\u00a0 If yours is one of the newer versions, the charge roll assembly will also include the cleaning roll.\u00a0 It will come off similarly to the DC250 version shown in the photo.<\/li>\n
  5. Remove the Drum as follows:<\/strong> Turn the cartridge on its left side so that the drum is presented upwards.\u00a0 Slide the front drum retaining clip forward and off (see Photo #5) and the rear drum retaining clip towards the rear and off.\u00a0 Now the drum with its two bearings can be lifted up and out of its cradles.\u00a0 This drum is very similar in design to the one on the black drum cartridge but the diameter is considerably smaller.<\/li>\n
  6. The Drum Blade comes off next<\/strong>. Remove 2 screws and cut the barcode sticker which is half on the drum blade\u2019s metal bracket and half on the plastic frame of the cartridge.\u00a0 Pry the metal \u2018C\u2019 clip off of the left side of the cartridge if one is present (see Photo #7).\u00a0 It is adhered in place by double sided tape.\u00a0 Now the blade will lift off.\u00a0 There is a thin Mylar piece stuck to the underside of the blade which serves like a chute which guides the waste toner from the blade to the waste toner auger.<\/li>\n
  7. Clean everything gently with a vacuum with a toner-rated filter.<\/strong>\u00a0 Be very gentle around the Mylar guide on the blade and also around the Mylar recovery blade on the frame opposite where the cleaning blade sits.<\/li>\n<\/ol>\n

    Replacing the Drum Reset CRUMs<\/span><\/strong><\/p>\n

    The original CRUM can slide out of its slot but the new replacement CRUMs will not fit in the same way because they have larger components. It is necessary to remove the rear end cover from the cartridge to replace the CRUM.\u00a0 See the photos below.\u00a0 Be very gentle with the replacement CRUM to avoid damaging the components.\u00a0 The replacement CRUM should be positioned as shown in the 3rd<\/sup> photo.<\/p>\n

    That is all you\u2019ll need to know on these guys!\u00a0 Very easy, very rewarding and environmentally friendly too!\u00a0 Happy Reconditioning folks.<\/p>\n
