Avatar Corporation distributes the EP-Connect coax interface for the Epson DFXseries and other Epson dot-matrix printers that use A-type interfaces. This EPConnect coax interface allows a connection to an IBM 3174/3274/3276 control unit
or 4300 series Display Printer Adaptor using standard type A coaxial cable.
When using EP-Connect and the DFX-series printers, there have been some
intermittent operational problems reported. It has been determined that this is
caused by the type of connector used on the EP-Connect interface that plugs into
the printer’s main controller board. There are two types of connectors that have
been used on the EP-Connect coax interface. One type is a “FUJITSU” connector.
The other is a “HONDA” connector. The “FUJITSU” connector has slightly shorter
pins than the “HONDA’ connector. Epson America, Inc. does
use of the EP-Connect interface that has the ‘FUJITSU’ connector unless it is used
on a unit that has the countermeasure described below.
To identify which connector type the EP-Connect interface has, simply look directly
at the interface connector. The “HONDA” connector will have the name “HONDA
printed directly on the black part of the connector.

There are approximately 1,600 of the EP-Connect interfaces on the market that
contain the non-approved “FUJITSU” connector. To accommodate these interfaces
Epson has taken a countermeasure on the DFX series printers. This involves
adjusting the position of the ORII/F circuit board and changing the securing points.
As a result, Epson only recommends the use of the Avatar board with the
“FUJITSU” connector on DFX series printers that have the countermeasure
installed. The starting serial
installed is outlined below.

This PSB provides a quick reference for the paper specifications on Epson’s current
line of 9-pin and 24-pin dot-matrix printers when using continuous paper. The
‘Maximum No. of Copies” is the maximum allowable number of copies when using
continuous multi-part carbonless paper. The “Total” number is the maximum
allowable number of copies including the original. The ‘Maximum Total Thickness”
is the maximum allowable total thickness including the original plus any copies.

Sound intensity is measured in units called Bels (named after Alexander Graham Bell,)
or more commonly in tenths of this fundamental unit: decibels. In making noise
measurements a weighting network is applied in an attempt to match the frequency
response of the instrument to that of the human ear. The most common is the A
weighting network, with resulting measurements expressed in dB(A).
The following is a list of current product’s noise levels tested in accordance with
standards set by the International Standards Organization (ISO). The acoustic noise
levels for the 9 pin printers are averages while printing in Near Letter Quality (NLQ)
mode using continuous paper and are not guaranteed figures. The acoustic noise
levels for the 24 pin printers are averages while printing in Letter Quality (LQ) mode
using continuous paper and are not guaranteed figures. The acoustic noise levels for
the laser printers are averages while using single sheet paper and are not guaranteed
figures.
