Xerox 5945 Drum Cartridge<\/p><\/div>\n

Xerox\u00ae<\/sup> WorkCentre\u00ae<\/sup> 5945 \/ 5955 Drum Cartridges\u2014<\/strong><\/p>\n

Repairing and Rebuilding the Print Cartridges for the WC-5945 & 5955<\/em><\/p>\n

The WorkCentre 5945 styles are new comers on the Xerox copier scene.\u00a0 These guys are black & white multifunction copiers.\u00a0 I got my paws on one of the drum cartridges and thought they looked intriguing. Some of the parts of this cartridge have already begun to become available, so that\u2019s always helpful. This month, we\u2019ll start with an overview of the cartridge, especially where the CRUM chip is situated. Then let\u2019s take one of these babies apart and see how to rebuild the upper half.\u00a0 We\u2019ll leave the lower half (the developer station) alone for the time being.<\/p>\n

The WC-5945\/5955 print cartridge is sold under the part number 013R00669 (13R669).\u00a0 It can be found online currently for between $115 and $140 for a new OEM cartridge.\u00a0 Not bad considering it has a stated yield of 200K according to the machine\u2019s brochure.\u00a0 The cartridge has an upper half which has the drum, blade, charge roll, and a cleaning roll (a white foam roll).\u00a0 The lower half has a developer station including an ATC Sensor (Automatic Toner Concentration).<\/p>\n

A first glance at the front end of this print cartridge would remind you of the C123 or WC-5225 drum cartridge.\u00a0 The lower half being a developer station is also reminiscent of a C123 or 5225 drum cartridge.\u00a0 That\u2019s where the similarities end.\u00a0 The parts in the upper half are longer than the C123, so nothing really crosses over up there.<\/p>\n

The drum reset CRUM chip looks more like one of the C35 style drum CRUMs.\u00a0 It can be found just behind the right side of the front end cover (see Photo #1).\u00a0 It is easily replaced (one screw, T-10 Torx bit).\u00a0 Replacing the CRUM chip will reset the drum count and allow you to extend the life of the cartridge considerably.<\/p>\n

Keep in mind that because the cartridge has developer in it, it\u2019s important that it be hand-delivered and not turned upside down during handling.\u00a0 This is because if it gets flipped over, the developer material can migrate up into the upper half where the drum and charge roll are at.\u00a0 This means that for now at least, you\u2019d not be able to ship a rebuilt cartridge.\u00a0 Unless you have replacement developer material, you will not want to clean out anything inside the lower half (developer station).\u00a0 Eventually replacement developer and a new developer pull-seal will no doubt become available and then a true full rebuild will be possible.<\/p>\n

Now let\u2019s get into the procedure of taking off the upper half and replacing the drum, charge roll, cleaning roll, and drum blade.\u00a0 This can get pretty messy, so make sure you are working over a drop-cloth. You\u2019ll also need a Torx T-10 sized driver bit.<\/p>\n\n\t\t
