    1050C Plus - Printing black rectangular blocks

    1050C Plus printing black seemingly random rectangular blocks (pics attached; 1st pic (rectangular blocks). I had this before once except was cyan and problem was bad main pca--a bad DIP chip as I recall. I suppose something could be up with the carriage pca. Printhead is new old stock 5/2010, yeah kinda old. I don't think a bad printhead would lay down ink in such an organized rectangular fashion; I would think it would just drip it out all over the hell.

    And I recall solid black printing at one end of the page or across entire page in relation to an "out of memory" or a "low memory" problem (2nd pic). Thinking "process in computer" (send job as bitmap) would maybe resolve.

    BTW, customer grabbed 5500 printer driver and started using it after being frustrated with an old? 1050C driver not working. I know the 5500 has worked for folks on the 1050C.

    Trying to figure out for customer, but they got tired for the day and quit.

    Any other thoughts?

    Thanks.

      Sorry, I can't seem to find the original post.

      I had an issue similar to this when we delivered a bizhub to this customer of ours for a demo by the IT department. They brought me samples of weird black geometric patterns overlaying the prints. Yes, they were PDFs of technical drawings, just like yours.

      I connected my laptop, and printed just fine. So what driver version are you using? ... oh, an HP laserjet 4 print driver? Somebody here made a reference to vector graphics. I'll see if I can find the original thread. =^..^=

      EDIT: Here are the samples, and it was a Copystar CS-2560:

      I found it in the Archives:
      Crop Circles?

      The short answer is that one of his endusers continued to fiddle with print driver settings, and had selected "vector" printing.

      If you'd like a serious answer to your request:
      1) demonstrate that you've read the manual
      2) demonstrate that you made some attempt to fix it.
      3) if you're going to ask about jams include the jam code.
      4) if you're going to ask about an error code include the error code.
      5) You are the person onsite. Only you can make observations.

          Seems that could be the right track--printer driver related. Again, they could not get working with the old driver I sent them, 1 I downloaded about 7-10 years ago maybe, so they used the 5500 driver.

          I think I will point them to the Vista 64bit HP-GL/2 driver (think that is the latest on HP's site) on HP's site.

          This indicates that it COULD BE the trailing cable as well but on a 750C:

              If printing a PDF try selecting print as image. I have found that has solved alot of issues by selecting the print as image.

                  Would that be: "optimize for images"? I don't think I've ever seen the selection "print as image" in a 1050C driver. Again, I have seen "optimize for images".

                  What 1050C driver would I see that option in or how do I migrate to it to select it?

                      The Print-As-Image function is only available in a PostScript print driver. =^..^=

                          OK, I see it, "print as image", one of the check boxes atop the print dialog. It does lie within the HP-GL/2 driver print dialog.

                          In the meantime, ol' Ralph McGranahan, RMB Services, Corona, CA told me: Yes, the image you sent to me with the all black and the black rectangles I think is a memory problem. Usually a power cycle on the plotter clears this up. I think this usually happens when there is something still in the plotter and possibly a corrupted plot data causes this. I don't think changing to process in computer or sending a bitmap is necessary, but you may have to also reset the computer. I doubt that the printhead is the problem.

                          Customer has not gotten back to me. I am going to "let a sleeping dog lie".

                              If they're printing PDFs and using Acrobat/Reader, have them try Foxit Reader instead. Adobe and Designets have never played nicely since the 450C. Using the 'print as image' option can help but generally only if the PDF is wonky. Sometimes just printing the PDF upside down will fix the problem. PDFs from AutoCAD are especially problematic with Acrobat because of all the layers needing to be flattened. This can take a long time in Acrobat/Reader, and take a fraction of the time in Foxit Reader.

                              Use the HP/GL2 Driver for Windows Vista x64. It's available from HP (still.) Install it as the 1050C or CM, it doesn't matter; the CM came with a hard drive, the C did not but it was optional. It doesn't matter because once you have the driver installed, go into the settings and set it to process the job 'in computer'. This puts the RIP process on the PC and not the printer. The printer will never run out of memory this way.

                              The option to 'optimize for images' or text only has to do with the way the printer puts down the ink. For text it can do bi-directional printing. For images, it's uni-directional in an attempt to hide banding. Either will work, one may look better than the other.

                              Post back with your progress!
