Digital photocopiers may save documents

by billso on Thursday, 15 March 2007

The Seat­tle Times reported yes­ter­day that most dig­i­tal pho­to­copiers save images to their hard drives.

These copies are more com­monly seen in large offices, but as their pric­ing drops, small offices and shops have been installing these dig­i­tal models.Now that I think about it, it actu­ally makes sense that the new gen­er­a­tion of copiers use hard dri­ves to make the copy­ing process faster.

After all, these copiers work like a com­puter. The copier takes a mas­sive dig­i­tal pic­ture of a doc­u­ment, and then uses a laser printer to out­put a paper copy that’s much clearer than older copy­ing systems.

The hard drive reduces the cost of the dig­i­tal copier. It would be expen­sive to store the dig­i­tal pic­ture in RAM. Hard dri­ves tend to be more durable than RAM, also.

This copy­ing method is also used in the small “all-in-one” units that I’ve seen in many homes. The scanner/printer uses the computer’s hard drive to store the image. For many home users, this method is very con­ve­nient, and less expen­sive than going to Kinko’s or using their office’s copier.

This tech­nique is also handy in high-volume com­mer­cial copiers — the kinds large busi­nesses use to pro­duce dozens or hun­dreds of copies.

While Sharp has rolled out a kit that will wipe or encrypt its’ copier hard dri­ves, most man­u­fac­tur­ers haven’t done the same with their mod­els. So a clever iden­tity thief could open a copier, grab the hard drive, and have access to hun­dreds or thou­sands of old copies.

If any of these copies show a birth cer­tifi­cate, pass­port num­ber, or account num­ber, the iden­tity thief can use that information.

Bet­ter yet, a police inves­ti­ga­tor could take an unen­crypted hard drive and search it for evi­dence in a case.

As I’ve said before, the only method I know for remov­ing data from a hard drive is to remove the drive, grab a big ham­mer and beat the drive into a man­gled mess of metal.
