    IMPORTANT SAFETY NOTICES PREVENTION OF PHYSICAL INJURY 1. Before disassembling or assembling parts of the printer and peripherals, make sure that the power cord is unplugged. 2. The wall outlet should be near the printer and easily accessible. 3. If any adjustment or operation check has to be made with exterior covers off or open while the main switch is turned on, keep hands away from electrified or mechanically driven components.
  • Page 18 SAFETY AND ECOLOGICAL NOTES FOR DISPOSAL 1. Dispose of replaced parts in accordance with local regulations. 2. Used ink and masters should be disposed of in an environmentally safe manner and in accordance with local regulations. 3. When keeping used lithium batteries (from the main processing units) in order to dispose of them later, do not store more than 100 batteries (from the main processing units) per sealed box.

  • Page 48: Separation Mechanism (Adf)

    When the feed roller feeds a sheet of paper, both the feed and the separation rollers rotate in the feed-in direction. However, if two or more sheets are between these rollers, the separation roller rotates in the feed-out direction to prevent the lower sheet from being fed into the scanner. C231...

  • Page 218: Introduction

    INTRODUCTION The Priport Controller is an external raster image processor designed to add a computer interface to Priport Digital Duplicators. Since it is separate from the Priport, the designers were able to use high-speed techniques making it one of the fastest add-on processors available. The Controller uses a high-speed 25-megahertz Intel 960-CA RISC microprocessor chip to achieve its high speed processing.

  • Page 219: Hardware Installation

    HARDWARE INSTALLATION The Controller connects the Priport to the computer using cables. (The computer and Priport are not directly connected to each other.) The inputs to the Priport Controller replicate those of a standard printer, including Parallel and AppleTalk® inputs. For the PC, the required cable is a standard IBM-PC parallel printer cable that is not included with the Controller.

    WINDOWS 3.1 AND WINDOWS 95 CONFIGURATION Step 1. Insert the Utility Disk in drive A. Step 2. In Windows 3.1 Program Manager, under File, select Run. In Window 95, go to Setting, Control Panel and double click on the Add/Remove Programs icon. Type or confirm "a:\setup" when prompted for the Program name and click OK.
  • Page 222 Step 9. Using the right or left arrow, highlight the "Install" pull-down menu and <ENTER>. Use the down arrow key to select "Save Configuration Changes" and <ENTER>. When all the configuration changes are completed, you must decide if you want to make them permanent. If you do not complete this step, any changes you have made during this session will be lost the next time the Controller is turned off.

  • Page 223: Configuration For Macintosh Computers

    CONFIGURATION FOR MACINTOSH COMPUTERS The “DigiPrint Utility” and several small configuration files are found in a folder named “DigiPrint Utility” on the PCRIP-EZ1 Controller Macintosh Disk. These small files contain the commands for changing the output page size, printing the diagnostic status page, saving configuration changes permanently and naming your Controller. (Naming your Controllers is necessary to distinguish between multiple Controllers connected to the same AppleTalk network.) Copy the entire DigiPrint Utility folder onto your hard disk for ease of access.

  • Page 224: Application Software Set-Up

    APPLICATION SOFTWARE SET-UP Each desktop publishing or word processing application needs to use the custom printer drivers for Graphic Device Interface (GDI) and QuickDraw (QD) printing provided on the utility disks with the Controller. These DigiPrint drivers are installed into the Windows 3.1, Windows 95 or Macintosh system folder using the following procedures: GDI Printing under Windows 3.1 Customized Driver Installation for Windows 3.1:...

Insert the floppy disk labeled Windows 3.1 Drivers in the floppy drive. The "Install Driver" window will provide a prompt for drive A:\.
  • Page 226 When the install process is completed, the printer name will appear in the "Installed Printers" dialog box on the upper half of the screen. Check to see that the new printer(s) just installed is hooked to the correct output port. If not, click on Connect to select the correct output port from the computer. You should verify that "Fast Printing Direct to Port"...
  • Page 227 For example, if you compose a document using the Ricoh VT1800 driver (300 dpi), for example, and then change to the Ricoh VT3800 driver (400 dpi), the page displayed on the screen WILL be reformatted due to a variation in font metrics at the different resolutions.
  • Page 228 Special note for Model VT3600 and VT3800 who use the Short Drum: Choose the standard Letter or A4 page size instead of Ltr (SD) or A4 (SD) page size in the page setup of your application software. If the paper is loaded correctly for the Short Drum (wide edge feed), the Priport's page size sensing will tell the Controller to rotate the image correctly to match the paper.

  • Page 237 The Video Interface board installed inside the Priport, which receives output data from the Controller, also receives status reports from the Priport itself. The DigiPrint Monitor polls the Video Interface board for status and receives back a status code. Each different status code reports a different condition of the Priport. Ready means that the Priport is ready to accept a print job.

  • Page 238: Commonly Asked Questions

    COMMONLY ASKED QUESTIONS How far can I have the Controller from the computer? The official specification for parallel cables recommends a length not greater than 10 feet (approximately 3 meters), however you can probably use a cable up to 25 feet (approximately 8 meters) without encountering any line communication problems.
  • Page 239 12. Will the PCRIP-EZ1 Controller work on a network? Yes, only with simple Macintosh "printer networks" AppleTalk/LocalTalk AppleTalk/PhoneTalk are supported. 13. What fonts are built into the Controller? None! Windows 3.1 and Windows 95 can use any True Type font. Macintosh can use all system fonts and True Type fonts.

    TROUBLESHOOTING The following are symptoms you might encounter and the appropriate solution for each: There is a quick flash of the ready light. An error condition has been detected in the Priport. First, check for a loose or missing cable between the Controller and the Priport.
  • Page 241 Make sure that the Controller is powered on and the Priport is on-line. If only one Macintosh is connected to the Controller, contact your local sales/service organization for additional help. The Controller's ready light starts blinking slowly as if it is processing a print BEFORE I have even sent a print job down.
