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.

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.
Page 23
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).

Acrylic-based labels are preferred.
Adhesive
the die cuts of the labels, or come in contact with any part of the printer. Labels that do not meet these
guidelines may damage the printer.
Use full label sheets. Partial sheets (with areas exposed by missing labels) may allow labels to peel off
during printing, causing a paper jam.
The label sheet and adhesive must not melt, release hazardous gases, or allow the cover sheet to come
off when the label sheet is exposed to the internal operating temperature or the ink of the unit.
If the unit is powered
using the paper release lever, before the unit is powered ON. This will prevent labels from peeling off of

Transparency
NOTES:
In general, only specially coated transparencies are recommended for use in inkjet printers. Select
transparencies specifically designed for inkjet printers.
The time required for the ink to dry on a transparency may be very long. Special precautions may be
required. The printed surface of the transparency should not be touched when removing the page from the
printer.
Multi-sheet transparencies
When printing multiple sheet jobs, remove each printed sheet from the output tray before the next sheet
enters.
It may be necessary to limit the amount of graphic heavy fill areas used in transparency printing.
Sometimes heavy fill areas cause the printed image to contract as it dries. The contraction causes poor
print quality.
Determine the suitability of transparencies before ordering or printing large quantities.

2.1 ELECTRICAL OPERATION
2.1.01 General Information
The OkiJet 2010 is a fully featured Windows-based, inkjet printer.
This product is a Graphics Device Interface (GDI) printer. Data leaving the computer is "pre-formatted" 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.
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.

2.2 MECHANICAL OPERATION
2.2.01 Paper Feed
Paper feeding is performed by the large and small feed roll assemblies, which are driven by the paper
feed motor assembly and the pick roll assembly.
At the beginning of the paper feed operation, the paper feed motor reverses momentarily to allow the feed
arm pawl to drop off the home position notch in the left side frame.
If the pawl fails to drop off the notch, check the feed arm assembly for binds, worn parts, and or broken
parts.
After the paper exits from the feed rollers, the paper feed motor reverses.
This causes the paper ejectors to move the last sheet of paper into the exit tray.
If the ejectors do not move or restore, check them for worn, loose, or broken parts.
Be sure that the ejectors are connected to the large feed roller shaft.
The pick roll assembly performs the manual feed process.
The large and small feed roll assemblies perform the auto feed process.

The unit is capable of the print speeds listed below.
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.
Page: 50
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.
Page 63
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).

2.2.11 Maintenance Station
The maintenance station has two functions.
1. It cleans the printhead nozzles during the print operation.
2. It seals the printhead when it is not being used. This prevents the nozzles from drying.
Maintenance Station Assembly
The carrier moves to the right over the maintenance station
A slot on the bottom of the carrier engages a tab on the sled of the maintenance station.
This causes the maintenance station caps to rise and seal the printhead.
Carrier movement to the left uncaps the printheads.
Page: 53
The wipers clean the printhead nozzles as the carrier leaves the maintenance station.
The wipers clean the printheads only when the carrier is moving to the left.
No wiping action (of the printhead nozzles) should occur when the carrier is moving to the right.
After the cleaning operation is complete, a tab on the maintenance station engages a slot on the carrier.
This lowers the wipers.
Wiper
A worn wiper causes degraded print quality just after a maintenance cleaning.
Cap
A worn cap causes the printhead nozzles to dry and clog.
