c654 Original Size Detection clarification & success story (me thinks)

[Synaux]

Hi, I have two Questions of curiosity:

"11.14.6 Original Size Detection
Copy Glass
(a) Use
• To change the size detection table for the document glass.
(b) Default setting
• The default setting varies depending on the marketing area.
(c) Setting item
• 'Table1'
• Table2"

Ok that is nice, but what is Table 2 for? There does not appear to be any further elaboration. There is a bulletin: "Detecting A4 and Letter size original from the glass" KBA00028946 which is also sufficiently vague.

"ADF Size Detection
(a) Use
• To set whether or not to give a priority to the detection of 8K/16K size when DF is used.
(b) Default setting
• K Size
(c) Setting item
• 'K Size'
• B series"

I assumed "B series" is the ISO standard, but doesn't make sense being in the US. And perhaps I am crazy, but I have never heard of a K size paper type. I just want to be able to understand what these two items actually mean.

Anyways, this machine was cutting off copies (when not using auto tray) and scans. Changing it to the default "K size" seems to have fixed the issue. The scans were particularly insidious as the screen does not show what the machine thinks the paper size is (as far as I can tell). Therefore, the user cannot determine if the scan is garbage until opening the scan.

Also (not huge concern), I cannot seem to find an option to make custom scan file names like on the older models??

Don't have manual handy but as for second question here:
Common Metric and Imperial Paper Sizes - Expedite

Thanks, but to only have two options, one being a an European ISO and a mystery "k size" is odd. If "K" is some esoteric code for US standard sizes (ANSI) that makes sense. The only other thing I can think of is 8k and 16k which makes no sense.

Ok, it is defined further in the Admin Settings section.

8.11.4 ADF Size Detection
• This setting is available only when “Others3” is selected in [Service Mode] -> [System 1] -> [Marketing Area].
(1) Use
• To set whether or not to give a priority to the detection of 8K/16K size when ADF is used.
(2) Default setting
• K Size (Taiwan)
(3) Setting item
• “K Size (Taiwan)”
• B Series (China)

Then I searched my entire database (fairly extensive) and this came up for the BH361

Sets the size detection of the bypass tray and those other than the bypass tray in B series or K size (8K/16Ksize).

So in practice:
7.67 x 10.5(8k) = 8.5x11 &
10.5 x 15.5(16k) = 11x17
Who woulda thunk it...

Lastly, I find it odd that the C364/C284/C224 manual claims that the default is “B series”

A mistake in a service manual? Impossible!

I've seen 8K and 16K paper sizes as standard on some Kyocera printers, but never knew what they were. =^..^=

haha, same here never really thought about it until now. Here is some light reading that I am sure will be fantastic subject material for your significant other:

Chinese extensions

The Chinese standard GB/T 148–1997,^[11] which replaced GB 148–1989, documents the standard ISO series, A and B, but adds a custom D series. This Chinese format originates from the Republic of China (1912–1949). The D series is not identical to the Swedish D series. It does not strictly follow the same principles as ISO paper sizes: The aspect ratio is only very roughly √2. The short side of a size is always 4 mm longer than the long side of the next smaller size. The long side of a size is always exactly – i.e. without further rounding – twice as long as the short side of the next smaller size.
