Multiplex Not Working

[Sharne]

Hi,

I have a new printer, a Kyocera TASKalfa Pro 15000c, and I’m struggling to get multiplex to work. The template has two sections, the first set to duplex and the second simplex. But the entire file prints duplex and does not switch from duplex to simplex. I have imported the PPD files and set it up as the following screenshots. It has been a while since I have configured a output preset to use a PPD, so perhaps I have made an error.

Any advice would be appreciated.

Regards,
S

Hi Sharne,
you should first check if the duplex and simplex command could be found in the output spool file. Print to a file, then edit it in NotePad or other and search for the duplex command.
You should be able to find the full command each time you print the first section.

Hi Yann,

Thanks for the assist. Reading a PostScript file is gibberish to me. Here is the first mention of duplex in the PS file.

%%BeginFeature: *EFDuplex TopTop
 userdict /XJXEFIsetpageproperties known
  { << /XJXsetduplex [ true ] /XJXsettumble [ false ] >> XJXEFIsetpageproperties }
  { userdict /XJXsetduplex known
    { true XJXsetduplex } { << /Duplex true >> setpagedevice } ifelse
    userdict /XJXsettumble known
    { false XJXsettumble } { << /Tumble false >> setpagedevice } ifelse
  } ifelse 
%%EndFeature
} stopped cleartomark
%%EndPageSetup

Does anything look incorrect to you? The above code snippet only shows twice in the test PS file, yet the PS file has 6 duplex pages. (and 2 simplex pages)

Hi Sharne, it looks correct. Do you also have some simplex commands in the spool file?

Hi Yann,

I tried searching for “simplex” and don’t get any results. Is there a better term to search for? I assume duplex false would be simplex rather than “simplex true”.

%%PageTrailer
%%Page: (3) 3
%%PageMedia: (Media 2 Green)
[{
%%BeginFeature: *EFDuplex False
 userdict /XJXEFIsetpageproperties known 
  { << /XJXsetduplex [ false ] >> XJXEFIsetpageproperties }
  { userdict /XJXsetduplex known
    { false XJXsetduplex } { << /Duplex false >> setpagedevice } ifelse
  } ifelse 
%%EndFeature
} stopped cleartomark
%%EndPageSetup

yes Sharne, Duplex Off is the right command for Simplex(regarding your ppd).

I can see it is activated for page 3(%%Page: 3).
So the Page 1 and 2 must be duplex I suppose, then page 3 simplex. Which seems to be the result you would like.
You should check if Page 4 get a duplex command, and page 6 a duplex off one. If so the spool file seems to be good.

So maybe the printer cannot accept mixplex (switching from duplex to simplex) or the duplex commands could be wrong. You could try another ppd file.

Hi Yann,

I do see a duplex command for page 4:

%%Page: (4) 4
[{
%%BeginFeature: *EFDuplex TopTop
 userdict /XJXEFIsetpageproperties known
  { << /XJXsetduplex [ true ] /XJXsettumble [ false ] >> XJXEFIsetpageproperties }
  { userdict /XJXsetduplex known
    { true XJXsetduplex } { << /Duplex true >> setpagedevice } ifelse
    userdict /XJXsettumble known
    { false XJXsettumble } { << /Tumble false >> setpagedevice } ifelse
  } ifelse 
%%EndFeature
} stopped cleartomark
%%EndPageSetup

But page 6 just reads:

%%Page: (6) 6
%%EndPageSetup

And so does every other page except page 14 which is the end of my test file:

%%Page: (14) 14
%%PageMedia: (Media 2 Green)
[{
%%BeginFeature: *EFDuplex False
 userdict /XJXEFIsetpageproperties known 
  { << /XJXsetduplex [ false ] >> XJXEFIsetpageproperties }
  { userdict /XJXsetduplex known
    { false XJXsetduplex } { << /Duplex false >> setpagedevice } ifelse
  } ifelse 
%%EndFeature
} stopped cleartomark
%%EndPageSetup

I will see if I can get another PPD file.

Just for clarification, my test file is as follows:
14 pages total.
Page 1-2 duplex
Page 3 simplex
Page 4-5 duplex
Page 6-7 duplex
Pages 8-9 duplex
Pages 10-11 duplex
Pages 12-13 duplex
Page 14 simplex.

ok, that seems to be correct.
To be sure you have to right duplex and simplex command, you can do the following:

• Open Word, create a 2 pages document with just one word on each page
• Print it to the printer simplex. Select Print to file.
• Do the same but with Duplex activated.
• Compare the 2 files. The difference will be the duplex vs simplex command.

If you cannot get the printer activating duplex correctly, please open a Support ticket. We would analyse it.
