Chapter 1 Product Specifications
1.1 OVERVIEW
1.1.01 General Information
The OkiJet 2010 is the first thermal inkjet product to wear the Okidata name badge. The unit is a fully featured Windows-based, inkjet printer.
This product is a Graphics Device Interface (GDI) printer. Data leaving the computer is "preformatted" for the printer. Very little printer circuitry is required for data handling. The received data is already formatted for the GDI printer. RAM in the printer is minimized.
There is NO operator panel. The unit is controlled via software in the computer. The units print resolution is 600 by 300 dots per inch. Dual printhead design allows the unit to print color and true black without changing printheads.
The unit utilizes an edge smoothing technique called Print Quality Enhancement Technique (PQET). This technique reduces the "jaggies" seen in slanted (italics) character set printouts.
The OkiJet 2010 printer is a "Windows Based Host Printer". The printer can print from a DOS based program running in a Windows "DOS-based session", but it is not the best possible configuration. DOS is a very non-graphical based operating system. The OkiJet 2010 is a GDI printer.
A parallel interface cable IS NOT shipped with the unit. The end user must purchase the interface cable separately. It must be capable of supporting bi-directional communications to connect the printer to the computer. This cable CANNOT be more than six (6) feet long.

1.6.07 Print Method
Thermal InkJet
InkJet printers work by spraying liquid ink onto the print media. The inkjet printhead-to-media gap is very small. A crease or sharp edge on the paper may damage the inkjet head. Paper dust or other contaminants can clog the inkjet nozzles on the printhead.
Page: 12
Perform the nozzle test to clean the inkjet nozzles.
printheads are delicate and easily damaged .
NOTE:
The printhead is part of the print cartridge. The printhead is replaced when the print cartridge is replaced. Black Print Cartridge: Average Life (Ink Saver OFF): 1000 pages at 5% coverage Color Print Cartridge: Average Life (Ink Saver OFF): 200 pages at 15% coverage of seven color graphics.
CAUTION:
Using a non-Okidata ink cartridge may damage the unit and void any warranties. Always perform the printhead alignment procedure when a print cartridge is replaced.
Guide or Section 3.3 for further information .
WARNING: NEVER
Refilling empty print cartridges with unapproved ink will invalidate the warranty. Incompatible inks can cause damage to the printhead or printer.

3 pages per minute in Black Draft Mode. 2 pages per minute in Black Letter Quality Mode. 2 to 4 pages per minute in Full Color Mode.
Graphics Device Interface (GDI)
When working with a GDI printer, data leaves the computer "pre-formatted" for the printer. Very little printer circuitry is required for data handling. The received data is already formatted for the printer. RAM in the printer is minimized. Because the printer is controlled via software in the computer, the operator panel is minimized.
Printer Speed versus System Speed
As a general rule, the faster the computer, the faster the printout from a GDI printer. Example: Two identical GDI printers are connected to two different systems. One system is a 25 MHz. 80386 based computer with 4 MB of RAM. One system is a 66 MHz. 80486 based computer with 8 MB of RAM.
Question
If both systems being printing the same file at the exact same time, which system will finish first?
Answer
The 66 MHz. 80486 based computer with 8 MB of RAM.
Reason
All of the pre-print data processing is being done in a system with greater "system resources" (more RAM, high level processor at a higher speed). Data is sent to the printer faster.
Windows Printing versus DOS Based Printing
The OkiJet 2010 printer is a "Windows Based Host Printer". The printer can print from a DOS based program running in a Windows "DOS-based session". However, this is not the best configuration. DOS is a very non-graphical based operating system. The OkiJet 2010 is a "Graphics Device Interface" printer. It is better to run the OkiJet 2010 with a Windows system.
Improving Performance
A GDI printer is the only type of printer that improves (up to the printers maximum rated performance) with the host computers improvement.
In the example, a 25 MHz. 80386 system was compared to a 66 MHz 80486 system. Performance gains come from improving the computer, not by adding extras to the printer. Upgrades will improve the customers computer system and the performance of the OkiJet 2010.
Upgrading to Pentium will allow software speeds and print speeds to increase (up to the maximum rated performance).

CAUTION:
For best results when printing with color, use coated paper. Paper types that work well with the color print cartridge may not work well with the black print cartridge. Since the quality of plain paper varies widely, test the print quality before buying large quantities of paper.
