I've Ran Across this several times now with the latest KX driver. Seems that Some information within the PDF to be Printed is just "Lost". Random Charcters will Drop For no Reason what-so-ever. I've Had This Happening Across Different Models also so It Has To Do With The Driver. One customer has a program called Shop Tech that generates PDFs from info that is used to creat the fabrication job they are working on. When you view the PDF on the PC screen, all information is there, but if you print it out, it will drop one letter out of a word and This isn't even consistant. I've Been Playing with the PCLs and different settings in the Driver, but geez, when they say they print it the same PDF to a stupid little Brother or HP printer with no problem, kinda makes the High Priced Fancy MFP look like a turd.

You did not mention what model you are having problems with :

Check the tech bulletins for your model, some of them have a firmware update that could help. I don't remember which models, but I remember something about 'dropped characters'.
Something concerning Adobe & PCL-XL,& KX drivers.

Good Luck

Thanks Eric I just had a customer on a two week old KM-5500i complaining about whole pages from PDF received by e-mail missing. Have not had any time to address problem yet. Is anyone else busy as can be ? Bringing attention to the new print driver is overdue.

I've Had This Problem With two Different Models So Far. On An 1128 and On A Voyager E model. I Didn't Seem To Have Any Problem With The Voyager with The Old 4.xx Version of The KX Driver and I Was Also Able To Make It Output Mixed Originals (11 x 8 1/2s and 11 x 17s)Stacked Properly So That They Would Staple in the upper left corner. With The Latest KX Driver I Can't Get It To Do This No Matter What I Try. I Had To Set It Up In LandScape Mode I Think with Letter Paper Loaded in 11 x 8 1/2 orientation in cassette 1 and 11 x 17 in cassette 2. Now it seems that it rotates the image the other direction so that they can't be stacked properly and stapled. All Firmware is Up To Date on Both Models Also.

I wonder if it would help if you went into the "Advanced" tab (shows up on the print driver screen only when printing PDF's) and selecting "print as image" or "let printer determine colors" (under color management section of the "advanced" tab) might help...??? Both of those checkboxes have worked wonders for fixing strange quality and processing problems in the past for me.

The Most Luck I've Had Is By Selecting The PCL 5x language and selecting CGI Compatible Mode. I've Had Other Customers that use Word Art in the Output they Produce for Realtors and with Certain settings not made right in the driver, the Word Art Character just prints out as a colored box.

Had the same problem with a big engineering firm, ended up using KPDL driver.
The PCL unidriver did a bit better than KX, but again, you could see in print preview that info was missing. Print as image is the only true way to get what you see.

Sounds a little like this:

In the end we just changed the default font.

Just had a customer today complaining of missing characters but from Excel, I believe the latest 2010. Tryied changing from PCL XL, to KPDL or PCL 5 same thing.
Recommended thier IT people upgrade to latest KX drivers.
Any body else seen this with Excel?

Hi guys, new, so be gentile. we have seen this on Sharp Equipment and the culprite seems to be Microsoft XPS printing language trying to be as good as PDF. Sharps fix is to buy an XPS lics upgrade like Postscript from them. The real fix is to make all Microsoft Docs (and others) a PDF then they print fine

Hope this makes sense

OK MarkK, I’ll be gentle. The problem has existed when printing PDF files for several years now. There seems to be no real reason, firmware version, or driver version that is the culprit. We have sent in examples to tech support years ago. We have never resolved teh issuie and it has not completely gone away.

I have seen the same thing, pieces missing from the print, but they show up on the monitor. Selecting "Print as Image" seems to fix the problem in virutally every case. I believe it is something to do with the layers in the PDF file not flattening correctly. I have seen this with both Kyocera and Okidata (Okidata uses Adobe PS3), but strangely never had a complaint with HP, probably because most HP's don't support Postscript, and if they print anything it is just random junk that the customer doesn't recognize as thier file.

Is the pdf set up where they can type on it?

I had a document like this that would leave voids. The problem ended up being if I left the mouse clicked on a line that was edited, the line would be void on the print-out. But if I clicked off the line (on any other part of the pdf) the document would print correctly.

It's a shot in the dark, but it might be what you are experiencing. Good luck.
