Section 1
About the EFP9800 Printer
The EFP9800 printer is a fast, quiet, reliable, and very compact multiple-
function printer. It prints receipts and a journal, validates and prints checks,
and prints on a variety of single- or multiple-part slips. An additional option is
the Magnetic Ink Character Recognition (MICR) check reader with parsing
which reads account numbers on checks for easy verification.
The industry-standard RS-232C and IEEE 1284 bi-directional parallel
communication interfaces allow the EFP9800 to be connected to any host
computer. The EFP9800 provides the following emulations: Epson 370/375
printers (included in the EFP9800 ESC/POS commands), Ithaca Peripherals
Proprinter emulation, NCR 5021 printer, (Serial Interface Only) and the EF4270
printer. These emulations provide easy integration into applications written for
these printers and emulations.

About the EFP9800 Printer
1–2 3255 4073–002
Note: A Running Change acoustic noise reduction enhancement was
released for the EFP9840 and EFP9841 serial interface units. This
Running Change incorporates a new solenoid clamp assembly and a
revised controller PCBA to further reduce acoustical noise. The
change was incorporated into factory production starting at serial
number 5108 67054. All EFP9840 and EFP9841 units with serial
numbers 5108 67054 and above will have the acoustic enhancements.
The new solenoid assembly has a bumper added to the plunger to
reduce noise. This new solenoid requires a new lower case and
therefore cannot be installed in The EFP9840 and EFP9841 units
below serial number 5108 67054.
The revised PCBA incorporates a modified print head pin firing
scheme. The PCBA fires the pins in staggered pairs to reduce
acoustical noise. This new PCBA is fully backward compatible with
previous style EFP9800’s.

Maintaining and Cleaning the Printer
There is no customer maintenance required for the EFP9800 printer. However,
you may occasionally clean the cabinet as needed to remove dust and finger
marks. Use any household cleaner designed for plastics, but test it first on a
small, unseen area. The cabinet finish and materials are durable and are
resistant to cleaning solutions, lubricants, fuels, cooking oils, and ultraviolet
light.
If the receipt paper bucket is dirty, wipe it with a clean, damp cloth.
Caution
Do not spray or try to clean the printhead or the inside of the printer with any
kind of cleaner as this may damage the printhead or the electronics.
