Open Prepress Interface
A workflow protocol developed by Aldus Corporation used in electronic prepress to link desktop publishing systems and high-end CEPS. Essentially, high-resolution color images are stored on a central network server, to which all the workstations are connected. Low-resolution files are sent by the server to individual computers working on page layout. The low-res images are imported into the page (in a kind of FPO way), positioned, and comments sent back to the OPI server provide specific cropping, scaling, positioning, and color information about the image. The servers PostScript driver inserts the proper instructions into the PostScript code. When the page is ultimately output to an imagesetter connected to the network, the high-resolution image is swapped for the low-res one, and the indicated instructions as to cropping, etc., are executed. The work with layout documents which include big graphic files (high resolution, big size) may become a test for someone’s patience due to the rate of the processing. The dealing with this kind of files, which need a lot of memory in the workflow, can be simplified with an Open Prepress Interface (OPI) System. Although the PCs and networks become constantly faster and powerful, OPI is used for the Prepress workflow in order to minimize the waiting period. It is in use for 10 years now, but only a few people know this application. If a graphic file is placed into a document, layout applications normally integrate the whole graphic file. If the graphic files are big, the processing of the document becomes very slow due to the quantity of the graphic data. The resources needed by the PC and the network (if used) are unnecessary, because low resolution graphic files are sufficient for the work on a monitor in order to create the layout or to judge the colours. Because of this, OPI-programs create low-resolution graphic files with the same dimensions and place them into the layout document instead of the originals. The high-resolution files are integrated by an OPI-server just after the print job is started. The OPI-server finds the data by so called OPI-comments, which are included in the PostScript print file or in a PDF file. These OPI-comments describe, among other things, the memory needed, the sizes, and the position of the graphics in the layout document. Another aspect is the possibility to share the work of one project between the graphics and the layout, because the final graphics are embedded after the print job is started.
OPI is useful for minimizing high-resolution-file travel on networks; their large file size can make traffic screech to a halt. And by utilizing only low-resolution viewfiles on workstations, processing speed is increased. The efficacy of OPI is contingent upon the use on the workstations of OPI-compatible software; many page layout programs are increasingly including support for OPI, although some OPI specifications for color separation havent been effectively nailed down yet. Although OPI is often compared to DCS, the latter is strictly a color separation protocol, while the former is more of a workflow protocol.

How to reset Canon MX318 printer Ink absorber is full Error Code 27 5B00
If you encounter a problem or an error like "Ink absorber is full" or Error Code 27 or "Error Code 5B00". Its mean that the Printer Counter Protection is Full and it required a reset and Ink wastepad replacement, if you want your printer to work again. There are two ways to reset the Canon MP (all in one) printer, One is by using a Software tool and the other is manually resetting the EEPROM of the printer. Below is the step by step procedure on how to reset your Canon MP (All in One) printer.
Please follow the step by step procedure to reset your Canon Pixma MX318 Printer
- Turn off the Printers.
- Press and Hold the "Stop/Reset" button then press POWER button.
- Release the "Stop/Reset" button while keeping POWER button on press.
- Press "Stop/Reset" 2 times and then release all the buttons.
- Note: If the above was properly performed the printer will enter the "Service Mode".
- Press the "Stop/Reset" button 4 times, this will select the clear waste ink counter function. The lamp will alternate (change) color with each key press.
Mode:
1. Service/Factory test printout, including ink sensor check.
2. EEPROM - Info printout.
3. EEPROM - Initialization.
4. Reset the Waste ink counter. - After selecting the desired mode (eg 4), press the POWER button to "set" the change, and return to the top of the function selection menu. Press the POWER button again to restart the printer. Or unplug the printer to turn off.
- On the Canon Pixma MX318 Printers, And your done!
Warning: Getting rid of the error message won’t change that you might end up with ink leaking out of the printer if you don’t either replace or clean the ink wastepad.

Ricoh Aficio SP 5200 SP 5210 configuration page
To see the page count for a Ricoh SP 5200 or SP 5210, you can print out a configuration page. In addition to the page count, the config page also has a lot of useful network information and printer settings. To print the config page:
- Press User Tools/Counter
- On the screen, select Printer Features
- Select Configuration Page
