Condition The machine does not print. Some color images come out all black. Some color images come out in unexpected color. The machine does not print whole pages and its output is half page printed. I encounter error "Cannot open port device file" when printing a document. Suggested solutions The CUPS (Common Unix Printing System) version distributed with SuSE Linux 9.2 (cups-1.1.21) has a problem with ipp (Internet Printing Protocol) printing. Use the socket printing instead of ipp or install later version of CUPS (cups1.1.22 or higher). This is a known bug in Ghostscript (until GNU Ghostscript version 7.05) when the base color space of the document is indexed color space and it is converted through CIE color space. Because PostScript uses CIE color space for Color Matching System, you should upgrade Ghostscript on your system to at least GNU Ghostscript version 7.06 or later. You can find recent Ghostscript versions at www.ghostscript.com. This is a known bug in Ghostscript (until GNU Ghostscript version 7.xx) when the base color space of the document is indexed RGB color space and it is converted through CIE color space. Because PostScript uses CIE color space for Color Matching System, you should upgrade Ghostscript on your system to at least GNU Ghostscript version 8.xx or later. You can find recent Ghostscript versions at www.ghostscript.com. It is a known problem that occurs when a color printer is used on version 8.51 or earlier of Ghostscript, 64-bit Linux OS, and reported to bugs.ghostscript.com as Ghostscript Bug 688252. The problem is solved in AFPL Ghostscript v. 8.52 or above. Download the latest version of AFPL Ghostscript from http:// sourceforge.net/projects/ghostscript/ and install it to solve this problem. Please avoid changing print job parameters (via LPR GUI, for example) while a print job is in progress. Known versions of CUPS server break the print job whenever print options are changed and then try to restart the job from the beginning. Since Unified Linux Driver locks port while printing, the abrupt termination of the driver keeps the port locked and therefore unavailable for subsequent print jobs. If this situation occurred, please, try to release the port. Condition The printer does not print PDF file correctly. Some parts of graphics, text, or illustrations are missing. Suggested solutions Incompatibility between the PDF file and the Acrobat products: Printing the PDF file as an image may solve this problem. Turn on Print As Image from the Acrobat printing options. NOTE: It will take longer to print when you print a PDF file as an image. Common Macintosh problems Condition The printer does not print a document from Acrobat Reader. The document has printed, but the print job has not disappeared from the spooler in Mac OS 10.3.2. Some letters are not displayed normally during the Cover page printing. When printing a document in Mac OS with Acrobat Reader 6.0 or higher, colors print incorrectly. Suggested solutions You should change the Print Method option to Print as Image when you print from Acrobat Reader. Update your Mac OS to OS 10.3.3 or higher. This problem is caused because Mac OS can not create the font during the Cover page printing. English alphabet and numbers are displayed normally at the Cover page. This problem is caused because the resolution setting in the printer driver may not be matched with that in Acrobat Reader. Make sure that the resolution setting in your printer driver matches that in Acrobat Reader. 9.17
