ImageClass D1150 Internal Storage

pungo120 — Sat, 04 Nov 2023 23:26:14 GMT

Can anyone tell me if the Canon "ImageClass D1150" has any non-volatile internal storage, including either solid state or HDD? I have one that I am going to be selling or giving away, and want to make sure there isn't any of my information (previous prints, copies, etc.) saved on some internal storage medium.

Thanks in advance!

I found the user manual, but it's a pain to use as it will download a ZIP of HTML files. Though in searching that entire set of files (I have special software to do that), I cannot find anything on the following terms: "internal storage", "internal memory", "storage".

Also, I would assume that printers wouldn't have copies of end-user information stored that couldn't be reset via a factory reset.

Hello!

Some models hold the WiFi name and password after resetting them (it looks like yours isn't one). You'll find info on impacted printers HERE.

Greetings,

The printer has both volatile and non volatile memory. You don't need to worry about the volatile memory since its erased when power is cut.

The non-volatile memory is different.

You don't need to worry about the SSID name and passphrase because this printer doesn't have wireless. In addition this information is encrypted and stored in hexadecimal format. So you would not only need pull the chip, read it successfully, decrypt it, but then know where someone lives, and travel there (get close enough) to their network to connect to it. Anything is possible, but the probability is low and if they have ACL enabled, you would need to spoof the MAC address too. Thats a lot of work.

Printed documents stored in non-volatile memory. A couple of things here. Most printers use a circular buffer. Data in, Data out, There is always something stored in the middle. Once again however, someone will need a way to read this information from the memory. It might be encrypted. Its also is not stored in a human readable format. Its going to be in UFRII, PCL, postscript, XML, etc. It might depend on the program they were printing from. Someone with malicious intent might get your taxes (if they haven't been overwritten) or the last 10 recipes from your wife's cookbook, kids book report, etc.

Non-volatile memory cannot be completely erased unless data is written to each and every cel or memory space on the storage. There are standards for securely erasing or wiping data from solid state memory or physical disks. The chances for recovery are diminished or become impossible the more times the storage is over written. For liability purposes Canon has a documented procedure for erasing data. The truth is however, data destruction is not instantaneous. It requires software and time. The steps that a 3rd party would need to take are not worth the time without some guarantee they were going to get something useful. With this knowledge, you can decide the level of risk associated with giving, donating or eWasting your printer.
