INTRODUCTION
This manual explains the operation principles and servicing procedures for the Citizen dot matrix printer DP750 series. It is written for personnel
servicing these printers in the field.
FEATURES
The DP750 series printer are a station printers providing 45 mm x 2 line print capability. Developed for POS/ECR applications, the printers offer the
following features.
• The High-performance 9-pin print head with a print speed of approx 3.0 lines per second ensures high-quality printouts.
• Clamshell design (opening and closing mechanism for the paper feed section) makes paper loading easy and facilitates easier maintenance.
• Pull-type paper transport reduces risk of paper jams.
• Versatile array of options:

CHAPTER 1. Printer Handling and Maintenance
(1) If printer paper other than the recommended
paper is used, print quality and service life
cannot be guaranteed.
Make sure that the paper width and quality
are within specifications.
(2) Protect the head surface from mechanical
shocks and from foreign objects.
(3) Remove any contamination from the print
head surface by lightly wiping with a cotton
swab moistened with ethanol or similar product.
(4) During transport and during extended
periods of non-use, remove the ribbon
cartridge.
(5) If the print head is powered while
condensation is present, the head may be
destroyed.
Make sure that any condensation has been
fully dried before starting to print.
(6) Loading paper
Cut the tip of the paper in a straight line and
make sure that the paper is not frayed, folded,
or creased.
When the paper emerges from above the
print head, grasp it and pull it out slightly, to
verify that it is set straight.
(7) Removing paper
Remove the paper only after printer operation
has ceased.
Pull the paper straight out in the same direction
which it emerges from the printer.
