Title: EEVblog #1100 - Dumpster Photocopier Repair

At work we use a slightly modern variant of this printer. The cable going into the empty space on the front panel is used for a RFID-like card reader so we can print from your workstation to a follow-me printer server. When we present our company badge to one of the many printers your print jobs are available in that printer.

By the way this is another example of our throw-away society. Often the repairs are simple but nowadays the replacement is cheaper or the technical knowledge to troubleshoot and repair is missing.

Oh hells, I've just sent ~150 brand new packs of ink blocks for Xerox printers (including that model) out for disposal.

Probably would have cost too much to send a few over to Aus though

This would be like a modern day "key card", a variant of the old mechanical counter plug in key which tracked the amount of copies printed per department for billing purposes?  Yes I do remember those,  :)

Unfortunately the cost of "disposables" which is a term I think Xerox coined many decades ago is so very expensive. 

I would have probably kept my very small Xerox 1020 (smallest of the Marathon series) as the dry ink and developer was so very dirt cheap.  I decided to get rid of it after reading in Xerox notes that the dry ink was considered a carcinogenic.  Also a small roller turned to goo, and I could never get The Parts Drop replacement to work right.

Not really, follow me printing uses one common print server so you can walk up to any printer in the enterprise, present it with your card and your print job pops out.

My bad, I read your explanation and when you mentioned "badge" my mind went direct to the idea of a Key Card.  Funny there's no port like that on a Xerox 2700 or 3700 network printer...   ;)

Oh it can be used for billing too, I've seen that as well, just not in the place I work now.

Oh, wow. I did not know that a photo copier might have a mechanical harddrive inside.

It is a serious security hole/hazard for people that print paper keys for their crypto-wallet "cold" storage. In some cases huge sums which the unwitting account holder thinks is now offline and not susceptible to any network hacks.

A copier that supports scanning the originals once and then printing out multiple copies collated (and perhaps stapled) needs plenty of storage. A hard drive is cheaper than gigabytes of memory.

Office photocopiers have been "scan first, send later" for at least two decades now.

That implies a storage device.

Mhmm, it can also be used in printers for font storage if you have custom corporate fonts, logos, document templates, page layouts, forms, even cheques etc. which is a godsend for anyone wanting to commit fraud

At my employer, the RFID badge readers are used for:
"Cloud printing" is used where your print job is cached on a server somewhere in the cloud, so potentially classified info is never stored on the printer, and jobs can be automatically deleted after 24 hours (or whatever) if you don't go to a machine to print it out.  Swiping your RFID badge authenticates you to the printer and the print server.  I wish we could do that with out computers...
